Context
What is the Regional Land Transport Plan
5. The
draft Regional Land Transport Plan (RLTP) is the Auckland region’s bid
for national funding for transport in Auckland. It is a 10-year investment
proposal.
6. Auckland
Transport (AT) produces the RLTP on behalf of the Regional Transport Committee
(RTC) which is comprised of members of the AT Board and includes
representatives from New Zealand Transport Agency (NZTA) and KiwiRail.
7. The
draft RLTP includes projects proposed in the national State Highway Investment
Proposal and KiwiRail’s Rail Network Investment Programme. It also
includes projects from the Department of Conservation.
8. After
local boards provide their feedback, the process to finalise and adopt the RLTP
has the following steps.
a) It is
considered and endorsed by the RTC and by Auckland Council’s Transport
and Infrastructure Committee (TIC).
b) The
final RLTP is submitted to the NZTA’s board for consideration no later
than 1 August 2024.
c) The
NZTA Board considers every region’s submitted RLTP and produces the
National Land Transport Plan by 1st October 2024. This sets out the activities
and projects provisionally expected to receive funding from the National Land
Transport Fund (subject to confirmation of business cases).
9. Auckland
Council’s financial contribution to the draft RLTP is set through the
Long-term Plan.
Local board views
10. The
statutory role of local boards within the development of the RLTP is to state
the expectations of their communities. Local boards do not decide whether
transport projects or programmes are included in the draft RLTP, but perform an
important role by providing a community perspective about the proposed
programme.
11. Local
boards are encouraged to present their feedback directly to the RTC during
hearings on 26 and 27 June 2024. Local board feedback is considered by the RTC,
which is the legislated decision-making body for transport matters in Auckland.
12. Local
board views will also inform the Transport and Infrastructure Committee when it
deliberates at its 4 July 2024 meeting.
Information about public engagement
13. Public
engagement was conducted from 17 May 2024 – 17 June 2024. The
engagement met the requirements for a special consultative procedure as
outlined in the Local Government Act 2002.
14. AT’s
engagement included:
· mailing notification of engagement to 550,000 households across
Auckland
· running radio, print and social media notification of engagement
· providing opportunities to engage electronically through the AT
website
· conducting more than 20 community drop-in sessions at which
communities could engage with officers from AT, NZTA and Kiwi Rail
· providing hard copies of the draft RLTP and paper submission forms
at libraries and Auckland Council service centres
· meeting with Auckland Council’s advisory panels
· constituting an RTC hearings panel and hearing submissions from the
public.

Analysis and advice
A summary of the draft RLTP
15. The
draft RLTP responds to the challenges of the region’s growing population
as well as Auckland Council and government transport policy. Specifically, that
the transport network is:
a) Fast and connected. Improvements that make
public transport faster, more accessible, and more reliable
b) Resilient. Investments that ensure our network
is ready for challenges and less vulnerable to storms, flooding and other emergencies
c) Productive. Projects that support regional
growth and productivity like technology to better manage traffic flow and make
journeys quicker and more reliable at peak times
d) Safe. Investments that support a network that
gets everyone home safely
e) Sustainable. Investments that help Auckland
reduce its transport emissions.
16. The
draft RLTP proposes a $63 billion programme of investment in renewals,
maintenance and operations, public transport services and new projects.
However, the costs of this programme are a lot more than Auckland is likely to
receive. Therefore, AT is leading engagement on behalf of the RTC on which
projects are the highest regional priorities for funding. The draft RLTP
proposes that the following items are effectively mandatory and should receive
funding in all circumstances:
a) renewal
and maintenance of local roads, rail and state highway networks, to ensure
these remain fit for purpose into the future and that whole-of-life costs and
disruptions are minimised
b) existing
public transport services, along with improvements such as more rail services
enabled by the City Rail Link and the expansion of the frequent bus network
c) completing
projects already committed to or in progress (for example, Eastern Busway and
City Rail Link).
17. This
leaves choices around which new capital projects should be a priority,
especially over the next three years. The main options are that AT concentrates
on:
a) smaller
projects that can be delivered quickly to improve the speed and reliability of
our bus and ferry network, including dynamic bus lanes, improved stations and
low-emissions options
b) larger
rapid transit projects that will provide new high-speed public transport links
across Auckland but will cost more and take longer to deliver
c) smaller
projects that can be delivered quickly to optimise traffic movement on our road
network and motorways and encourage more sustainable travel from key growth
areas
d) major
state highway projects that will improve resilience, reliability and travel
times on the motorway network and enhance our links to other regions
e) cycling
projects that will increase the size of the cycling network
f) investment
in safety infrastructure to reduce deaths and serious injuries on our transport
network.
18. The
draft RLTP proposes that public transport projects are generally our highest
priority for funding, followed by projects to optimise local roads, address
growth challenges and expand the cycling network. It concludes that delivering
all of the State Highway improvements, while still important, is a lower
priority for available funding.
19. The draft RLTP also includes a proposal for the Local Board
Transport Capital Fund of $62.8 million across all local boards over three
years. For comparison, the fund was $7 million for the 2023/2024
financial year, but in the draft RLTP this increases to $19.8 million for
2024/25, $21.3 million for 2025/26 and $21.7 million for 2026/27. Local boards
are recommended to provide their views on the proposed increase to the fund in
their feedback.
Providing local board views
20. RLTP’s
are developed every three years. This is an opportunity for local board elected
members to influence longer-term transport planning in Auckland.
21. AT
recommends local boards use all the information gathered from their local board
plan, the Long-term Plan and RLTP processes to help inform their feedback.
22. Additionally,
all local boards are supported by an AT Elected Member Relationship Partner
(EMRP) who has provided opportunities for workshops or discussions with subject
matter experts about the draft RLTP. The workshops were also an
opportunity to support local boards to prioritise their feedback.
23. The
Manurewa local board workshopped the draft RLTP on 6 June 2024.
24. Attachment
B provides the workshop presentation with the EMRP’s advice, using their
local knowledge of the area.

Climate impact statement
25. AT
engages closely with Auckland Council when developing strategy. The actions and
measures that support the outcomes sought by the Auckland Plan 2050 and the
council’s directions on climate change through
Te-Tāruke-ā-Tāwhiri: Auckland’s Climate Plan all inform
the priorities. The draft RLTP is informed by these discussions and AT reviews
the potential climate impacts of all projects to minimise carbon emissions.
Ngā whakaaweawe me
ngā tirohanga a te rōpū Kaunihera
Council group impacts and views
26. The draft RLTP is developed with input from Auckland Council, the
Mayor’s Office, officials from Auckland Council and the Transport and
Infrastructure Committee.
27. One of the most important council inputs is the budget expectations
set for AT during development of the Long-term Plan. This process
confirms Auckland Council’s funding offer to AT that is made based on
agreed assumptions about levels of service.
Ngā whakaaweawe

Local impacts and local board views
28. Local
board plans inform development of the council’s Long-term Plan which
identifies levels of transport funding that AT should expect from Auckland
Council. Local board plans are reviewed by AT and provide information that
informs transport planning. Essentially, the draft RLTP is the result of a long
engagement with local boards and the community.
29. The
RLTP team engaged with local boards directly in October and November 2023. The
team discussed current priorities and plans for engagement.
30. During
the same period, local boards received their annual AT Forward Works Programme
briefing that provided an update about AT’s current and planned work
programme. In March 2024, local boards provided feedback about their
priorities, which was shared within AT.
31. The
draft RLTP was endorsed by the Transport and Infrastructure Committee and
approved by the RTC for consultation. This was then circulated publicly on 17
May 2024, initiating a month-long period of public engagement.
32. Local
boards were able to request information about the draft RLTP either by asking
their AT Elected Member Relationship Partner or contacting the project team
directly. Elected Member Relationship Partners organised workshops with local
boards to discuss providing feedback.
33. The
Manurewa local board workshopped the draft RLTP on 6 June 2024. Attachment B
provides the workshop presentation with the EMRP’s advice, using their
local knowledge of the area.
34. Additionally,
local boards are provided with summaries of feedback from public consultation
in their area.

Māori impact statement
35. Auckland
Transport is committed to meeting its responsibilities under Te Tiriti o
Waitangi and its broader legal obligations in being more responsible or

36. Auckland
iwi were engaged during the development of the draft RLTP and were individually
informed of the public engagement.
37. AT’s
Māori Responsiveness Plan outlines the commitment to 19 mana whenua iwi in
delivering effective and well-designed transport policy and solutions for
Auckland. We also recognise mataawaka and their representative bodies and our
desire to foster a relationship with them. This plan is available on the

Financial implications
38. There
are no direct financial implications for local boards in receiving this
report.
Ngā raru tūpono me
ngā whakamaurutanga
Risks and mitigations
39. Broadly,
the key risk associated with this RLTP is increased public expectations for
delivery of projects that may not receive National Land Transport Plan funding.
This will be mitigated by highlighting key parts of the programme that are
expected to be subject to higher risk, based on Government Policy Statement on
Land Transport 2024 activity class allocations. There is also a risk that NZTA
does not fund elements of AT’s programme contained in the RLTP.
40. The
most significant direct risk to local board budgets is a reduction in the
currently proposed Local Board Transport Capital Funding. Local boards
can mitigate this risk by clearly advocating their position on this fund.
Ngā koringa ā-muri
Next steps
41. The RTC will review the feedback from all local boards and consider
it during its deliberations about the RLTP.
42. Local board formal views will be provided to the Transport and
Infrastructure Committee when it resolves on the RLTP at its 4 July 2024
meeting.
43. The
draft RLTP will be considered by the RTC and confirmed by 1 August 2024, after
which the document becomes a confirmed programme for transport work in
Auckland.

Endorsment
of the Pahurehure Inlet Shoreline Adaptation Plan
File No.: CP2024/05500

Purpose of the report
1. To seek ohia /
endorsement for the Pahurehure Inlet
Shoreline Adaptation Plan in Attachment
A.
Whakarāpopototanga matua
Executive summary
2. Shoreline
adaptation plans (SAP) are being developed across Auckland to provide a
long-term adaptation strategy for council-owned land and assets in response to
the impacts of coastal hazards and climate change (including sea-level rise).
3. Development
of plans for Manukau Harbour North, Manukau Harbour East and Pahurehure Inlet
(this shoreline adaptation plan) are being undertaken in parallel (referred to
as ‘Tranche 1’). This tranche will complete shoreline adaptation
planning for the Manukau Harbour.
4. Mana
Whenua engagement with local iwi Ngāti Te Ata Waiohua, Ngāti Tamaoho,
Waikato – Tainui, Ngaati Whanaunga, Te Ahiwaru and Te Ākitai Waiohua
was initiated in May 2023. The values of mana whenua and local iwi have been
applied through the selection of adaptation strategies and development of the
Pahurehure Inlet Shoreline Adaptation Plan and will continue through
implementation.
5. The
Manurewa Local Board provided feedback on the development of adaptation
strategies in 2024 workshops. In particular, the board provided direction on
engaging with local iwi and community groups, while considering the aspirations
of local community and wider coastal users of boats and coastal access at
Weymouth.
6. Community
engagement for Pahurehure Inlet SAP ran in parallel with Manukau Harbour East
and Manukau Harbour North as Tranche 1. This commenced in June 2023 and closed
in August 2023. Community groups, local board members and ward councillors
demonstrated significant interest and support for the community engagement
events.
7. The
Pahurehure Inlet SAP, provided in Attachment A, includes adaptation strategies
for each ‘stretch’ of shoreline, to provide guidance on how
council-owned land and assets can be adapted over time to sustainably manage
the escalating impacts of coastal hazards and climate change.
8. The result of the development of these strategies has demonstrated that, within the Manurewa Local Board’s
area of the Pahurehure Inlet SAP (Units 5 and 6), many areas of the
Wattle Downs and Weymouth shoreline can be managed over the next 100
years through limited intervention.
9. Hold
the line is identified for the Greers Reserve to Weymouth Wharf and Te Pua /
Keith Park (stretches 27 and 29) to maintain existing infrastructure and highly
valued coastal connections and land, while acknowledging an increased risk from coastal inundation
over time. Managed retreat is identified in the long term for Te Pua / Keith
Park due to the increasing risk from both inundation and erosion including the
impacts of climate change and sea level rise. Assets within the western extent
of the Weymouth Peninsula (stretch 30) are also identified as requiring managed
retreat in the long term and planning for both areas will need to respond to
iwi and community values, needs and aspirations.
10. The
strategies selected in the shoreline adaptation plans do not commit council to
any additional investment and no financial investment decisions have been made
at this time. They will be integrated into relevant council documents and plans
including asset management plans and help to inform the appropriate maintenance
and renewal of assets.
11. Staff
recommend that that the Manurewa Local Board endorse the Pahurehure Inlet
Shoreline Adaptation Plan, as a guiding document to manage and adapt
council-owned land and assets to the impacts of coastal hazards and climate
change over time.
12. Following endorsement from the Manurewa
Local Board (along with Franklin
Local Board and Papakura Local Board), the Pahurehure Inlet Shoreline
Adaptation Plan will be presented to
the Planning, Environment and Parks Committee for approval in 2024.
Ngā tūtohunga
Recommendation/s
That the Manurewa Local Board:
a) ohia / endorse
the Pahurehure Inlet Shoreline Adaptation Plan in Attachment A.
Horopaki
Context
13. The
Coastal Management Framework adopted by the council in 2017 (ENV/2017/116)
set the direction for a regionwide shoreline adaptation plan (SAP) programme
and responds to the priority area in Te
Tāruke-ā-Tāwhiri: Auckland’s Climate Plan, that
“communities and individuals are prepared for our changing climate and
coastline”.
14. The SAP work programme is focused on how we manage and adapt
Auckland Council-owned land and assets to the impacts of coastal hazards and
climate change over time. The SAPs are non-statutory
living plans which guide asset management planning and decision making.
15. As SAPs are developed and approved they are added to
the Auckland
Design Manual and are available on the Auckland
Council website as they are approved.
16. Once
the Pahurehure Inlet Shoreline Adaptation Plan (Pahurehure Inlet SAP) has been
endorsed by the associated local boards (Manurewa, Franklin and Papakura),
staff will present the Pahurehure Inlet SAP to the Planning, Environment and
Parks Committee for approval.
17. Once
each SAP plan is approved it will inform regional prioritisation and funding of
implementation actions. They also present an opportunity for iwi and other
programme partners to collaborate in their implementation.
18. Development
of the Pahurehure Inlet SAP has included
engagement with ngā hapū me ngā
iwi o Tāmaki Makaurau, the nineteen iwi of Tāmaki Makaurau and
recognises that each iwi is wholly autonomous, individual and unique.
Engagement also included the Manurewa Local Board, local community and relevant infrastructure providers such as
Auckland Transport and Watercare Services. This engagement identified specific
values and objectives, and in combination with the technical results of a coastal hazards exposure assessment and advice from asset owners, these objectives are
used to determine shoreline adaptation strategies.
19. The strategies provide high-level guidance on how council-owned land
and assets located in coastal areas can be adapted over time to sustainably
manage the escalating impacts of coastal hazards and climate change. The
strategies are covered in Table 1.

Maintain and making safe.
· Works may
be undertaken to repair existing protection structures for the purpose of
extending the asset’s life.
· Works may
support moving back the coastal edge (seawalls) and council owned assets,
such as playgrounds, pathways and amenities.
· Does not
support keeping the coastline in fixed position.
|
|
No active intervention
|
Natural processes are allowed
to continue.
· No
investment in the provision or maintenance of any hazard protection
structures associated with coastal hazards and flood protection (does not
apply to the management of land stability or subsidence or other man-made
hazard risk management).
· Applies
only where council-owned land and assets are not exposed/vulnerable to
coastal hazard and catchment flooding risk.
|
|
Hold the
line
|
The coastal edge is fixed at a certain location.
· Defence of the
coastal edge may be through nature-based options (for example beach
nourishment) or engineered hard structures (for example sea walls).
· Nature-based options
preferred, if possible, but in most cases engineered hard structures would be
required.
· An identified use or
service is maintained within its existing location, for example a road or
parks’ land uses.
· Could result in
losing intertidal areas or beach space due to preventing a landward
realignment of the coast in response to sea level rise.
|
|
Managed
retreat
|
Assets and land uses are relocated or realigned.
· Relocation or
realignment from hazard-prone areas to reduce risk to assets and maintain
identified values (including ecological, cultural, recreational).
· Relocation is planned
and undertaken proactively over time.
· Planning to retreat
or relocate assets and land uses are responsive to community, cultural and
ecological opportunities needs and aspirations.
· Supports opportunity
for nature-based solutions, and maintenance of coastal values.

20. The
process of developing the draft Pahurehure Inlet SAP and resulting
recommendations are discussed below.

Analysis and advice
21. The Pahurehure Inlet SAP (Attachment A) includes the area of the
coastline from the Puhinui Creek in the north culminating at Karaka Point
south. This coastline includes three local board areas. The areas of the coast
or ‘units’ which are located within the Manurewa Local Board area are Units 5 and 6 as identified in Figures 1 and 2
below. The analysis below includes a specific focus on the coastal areas
included within Units 5 and 6.
|
|
|
|
Figure 1: Unit 5 located within the Pahurehure Inlet
SAP area
|
Figure 2: Unit 6 located within the Pahurehure Inlet SAP
area
|
22. Research
and analysis were undertaken to inform an understanding of coastal processes,
coastal hazards and the resulting risk to council-owned land and assets, along
with identified ecological, cultural and historic heritage features. This
assessment influences the selection of adaptation strategies and includes the
following notable findings.
· The Pahurehure inlet is a relatively low wave-energy environment,
sheltered from the prevailing southwest to west sector by the narrow inlet
entrance, and with short wave fetches (the distance over which the wind blows
across the water to generate waves) within tidal basin and narrow creeks. The
shoreline with the highest wave exposure in the Pahurehure Inlet SAP area is along the western margin of Weymouth peninsula.
· The land in the Pahurehure Inlet Shoreline Adaptation Plan area is
in many areas sufficiently elevated to assist in the mitigation of sea-level
rise impacts (refer to Figure 4). However, there are some low-lying areas that
will be exposed to the impacts of ongoing sea-level rise if unprotected,
including Park Estate, Bottle Top Bay, Brylee Reserve, Longford Park and Wattle
Downs. Similarly low-lying areas, such as the upper Waimahia Creek (Weymouth)
and Conifer Grove stormwater ponds will be affected by coastal inundation,
which are likely to increase in extent and frequency when the sea level rises.
There are discrete low-lying areas, some of which include assets such as at Te
Pua / Keith Park in Weymouth and sections of coastal walkway, that are exposed
to coastal inundation that will be made worse with sea-level rise. Other parts
of low-lying peripheral coastal land including areas on the western side of the
Weymouth peninsular are likely to become exposed as sea-level rises, see to
Figure 3 below.
|
|
 |
Figure 3: Coastal
inundation for 1% annual exceedance probability or 1 in 100 year storm surge
for present day and with 0.5m, 1m and 2m sea level rise.
23. The
cliffs and coastal slopes along the Pahurehure Inlet shoreline are prone to
erosion. Due to the complexity of the combination of the forces acting upon the
land, various parts of the shoreline erode at different rates.
24. Coastal
instability and erosion along this shoreline will be greater in areas of
increased exposure, where there is greater wave exposure, and where the
cliff/slope is over-steepened and has little vegetative cover. Climate change
and associated sea-level rise will likely worsen natural processes leading to
slope instability and erosion.
Adaptation strategies support ecological outcomes
25. An
assessment of available information was undertaken to identify important
ecological features and opportunities to support ecological outcomes within the
selection of adaptation strategies. This assessment is summarised in Attachment
A – Section 2.
26. The
Manukau Harbour catchment has undergone significant modification and changes in
land cover over time which has resulted in a significant loss of native habitat
and fragmentation.
27. Specific
ecological considerations that have informed the development of the Pahurehure
Inlet shoreline adaptation strategy are:
· unique ecosystems including intertidal sand and mudflats, beaches,
wetlands, mangroves and grasslands
· coastal vegetation and habitat for roosting shore birds
· eight significant marine ecological areas and 19 significant
terrestrial ecological areas
· one biodiversity focus area, located within Puhinui Reserve which
guides the delivery of conservation activity.
Social, policy and cultural context support adaptation selection
28. An
analysis of the social, policy and cultural context was undertaken and provided
important context for the selection of adaptation strategies. Key elements
which are central to the development, change and use of the Pahurehure Inlet
coastline are identified below.
· The Pahurehure Inlet SAP
area largely covers an established urban area and new residential development which are concentrated along the shorelines of Pahurehure Inlet No.2, Conifer Grove,
Wattle Downs and Weymouth. The area includes mixed use, such as residential and
aged-care facilities, and commercial and industrial land around Pahurehure
Inlet No. 1, Drury and Clendon.
· Coastal access is concentrated in areas close to
residential areas and includes a
network of paths and tracks, and coastal parks. Engagement feedback identified
highly valued coastal walking connections and aspirations to expand such
networks (refer to section 2.5, 2.6 and section 4.0 of Attachment A). Key boat
launching facilities are located at Weymouth
and Bottle Top Bay.
· Engagement with resident groups including the Weymouth and the
Wattle Downs Residents and Ratepayers groups, local board members and the Manukau Harbour Forum is detailed in
Attachment A- section 4.0.
Local input into local issues
29. Community
engagement informs the development of the shoreline adaptation plans by
identifying how the community use and value their coastal areas.
30. The
SAP programme does not include consultation with the community on the selection
of adaptive strategies.
31. Community
engagement was delivered in person and digitally as follows.
· 
Tranche 1 SAPs ran in parallel and included a series of in-person, public out-reach events to inform people
of the SAP programme and receive feedback. Public engagement was open from 23
June - 7 August 2023. Events were
held at local venues as identified in Attachment A – section 4.
· Digital engagement for the Pahurehure Inlet SAP was undertaken using
Social Pinpoint and Engagement HQ. Social Pinpoint, an online engagement
platform, provided 57 comments pinned to an interactive map for the Pahurehure
Inlet SAP. Engagement HQ received a total of 68 surveys. Feedback also included
email submissions and direct
discussion which was presented to local boards.
32. An
analysis of the results was undertaken to develop high level community
objectives for adaptation strategies and includes the following categories as
outlined in Table 2. Engagement with local iwi and asset owners is captured
separately and is discussed in further detail below.

Community objectives for the Pahurehure Inlet Shoreline
Adaptation Plan
|
|
Coastal connections, use
and access
|
1. Community connections to coastal areas are
maintained and strengthened in a manner which responds to the
natural character, features
and ecological outcomes for
different areas of the coast,
providing access and connection for diverse users.
2. Coastal
infrastructure is designed for all coastal users and located
appropriately to support safe and maintained access to
and along the coast, both for land and water-based activities.
3. Priority areas for
access and recreation include Conifer Grove walkway, Karaka Harbourside
walkways, Wattle Downs beaches and the Weymouth beach/wharf.
|
|
Environmental
|
4. Catchment and coastal
habitats and biodiversity are valued, supported and restored, utilising local
knowledge and supporting local communities’ stewardship of their local
coastal areas.
|
|
Cultural
|
5. Coastal management
aims to enhance understanding and recognition of the rich cultural landscape
across the Pahurehure Inlet and wider Manukau Harbour, and in doing so aligns
with the aspirations of local iwi.
|
|
Responding to
risk
|
6. Coastal erosion and other
natural hazard and climatic impacts on coastal areas are identified and
planned for, enabling proactive, management of risks and impacts to support
the resilience of community facilities, assets and valued species and
ecosystems in hazard zones.
|
Developing the adaptation strategy for Pahurehure inlet
33. The
Pahurehure Inlet shoreline has been divided into a number of coastal units,
defined by the driving coastal processes and other key geographical features
(see attachment B). Within those units, stretches have been developed to
reflect the differing distribution of infrastructure and assets and the
approach to management of these areas.
34. The
following two units and respective 11 stretches are located within the Manurewa
Local Board area as identified in Table 3.

|
35. Much
of the Pahurehure Inlet shoreline can be managed over the next 100 years
through limited and no active intervention (refer to table 6.1 in section 6.0
for a summary of the adaptation strategies in Attachment A). Specific areas
have been identified where hold the line is required to maintain existing
infrastructure and highly valued coastal connections and land. Managed retreat
is identified to signal the need for proactive management of land uses and
assets where increasing risk from coastal hazards will impact the long-term
feasibility of maintaining all uses within a specific area.
36. There
are several closed landfills (council managed) located within the Pahurehure
Inlet SAP area. Management of these closed landfills are determined by the
Closed Landfill Asset Management Plan 2021. This plan is renewed every five
years and the Pahurehure Inlet SAP strategies may need to be revised to reflect
the future management of these closed landfills.
Shoreline adaptation strategies and timeframes for the
Pahurehure Inlet
37. The
Pahurehure Inlet adaptation strategies for the Manurewa Local Board area are
discussed by timeframe and summarized below (refer to Attachment A - Table 6.1
and figures 4 above, and 5 and 6 below).
· Short term: next 20 years
(refer to figure 5)
o Limited intervention: much of the
shoreline can be managed through supporting the continued management of existing
defences and maintenance of assets in their current location. Where assets are
renewed or new infrastructure developed within units 4 and 5, the location or
alignment of pathways and design of assets should be carefully considered to avoid hazard
areas and ensure they are resilient to
the impacts of flooding where they
are located in low lying areas.
o No active intervention: for stretch 22,
Kauri Point and 24, Kuurae, (name shared by Ngaati Te Ata Waiohua) locally
known as ‘Kimptons’) within Wattle Downs. This reflects the
presence of minimal or no council owned assets.
o Hold the line: for stretch 27: Greers
Reserve to Weymouth wharf and stretch 29: Te Pua / Keith Park reflect the
highly valued recreational boating access including a boat launching ramp,
Weymouth Wharf, Weymouth Yacht Club and grass reserves with park picnic
amenities. Keith Park has also been identified by the community and through iwi
engagement as having high recreational and cultural value. The esplanade
reserve provides an important connection to the Manukau Harbour.
Figure 5: Short term adaptation strategies by coastal stretch,
Pahurehure Inlet
· Medium term (20-60 years) refer to Figure 5
o Limited intervention: remains the most
prevalent strategy for Units 5 and 6. Noting that in lower lying areas, such as
the Waimahia inlet (stretch 25 and 26) inundation risk may increase and the
management of existing assets, including road ends (such as Stretch 28
Te-rangi-o-te-pua-karaka) will be required to ensure they are safely maintained
to provide access.
o Limited intervention for both Units 5
and 6 includes opportunities for reconfiguration of assets to avoid hazards and
reduce ongoing maintenance requirements from increased exposure to coastal
inundation flooding. Coastal connections such as the coastal walkway can be
realigned to avoid increasing exposure to hazards and areas with wider parks
areas such as St Annes reserve (stretch 23) can be reconfigured by providing space for a coastal ‘backshore’
(the area of a beach above the hightide line) resulting in a wider high tide
beach area for birds and people to utilise.
o Hold the line is retained for stretches
27 and 29 (Weymouth Wharf and Keith Park) where community use and values
support the continued maintenance and investment in assets in these locations.
Figure 6: Medium term adaptation strategies by coastal stretch,
Pahurehure Inlet
· Long term (60+ years) refer to Figure 6
o In the long-term limited intervention is maintained for many
areas including stretch 31 where there are opportunities to promote
restoration planting along the coastal fringe and long-term restoration of
indigenous biodiversity and cultural values with local iwi.
o Managed retreat is required in the long
term for Keith Park to reflect the need to consider the ability to accommodate
all the existing activities located within the park with an increasing risk
from inundation, assuming over 1m of sea level rise, and erosion. Planned
retreat for Keith Park will require wider iwi and stakeholder consultation and
planning.
o Managed retreat is also identified in
the long term for Stretch 30 Weymouth Peninsula, this is due to the increasing
inundation risk to assets and facilities such as the low carparking area.
Alternative locations may need to be explored within the local area to support
the relocation of uses (such as the car park), this will require proactive planning
in collaboration with iwi and community.

Pahurehure Inlet
38. The
Manukau Harbour is of cultural significance to iwi, including the location of
significant sites. These sites are located within esplanade reserves, the
coastal marine area, or in private ownership (for example stretch 24 Kuurae).
Engagement with iwi is ongoing and Ngāti Tamaoho, Ngāti Te Ata
Waihoua, Te Ākitai Waiohua and Waikato Tainui, are anticipated to provide
further cultural statements which will inform and support the implementation of
the SAPs across their rohe.
Request for local board endorsement
39. This
shoreline adaptation plan is community informed, incorporating proactive
guidelines on managing coastal hazard impacts on local ecosystems, recreation
and valued coastal connections, while being inclusive of mana whenua values and
supporting the resilience of local communities.
40. Staff
recommend that the Manurewa Local Board endorse the Pahurehure Inlet Shoreline
Adaptation Plan as a guiding document to manage and adapt council-owned land
and assets to the impacts of coastal hazards and climate change over time.

Climate impact statement
41. The
SAP work programme is funded as part of the council’s climate action
package and is a core climate adaptation workstream. As global temperatures
rise, Tāmaki Makaurau is predicted
to experience between 0.6 m and 1.5 m of sea level rise by 2130, depending on the future CO2 emissions scenario. The impacts of climate change and sea-level rise are
expected to increase the frequency, intensity
and magnitude of natural hazards including coastal erosion, coastal
inundation, and rainfall flooding.
42. To
prepare for the future with climate change, we need to plan adaptively.
Shoreline adaptation plans will help
reduce asset exposure and signal the need to
work with nature by developing natural systems (such as wide beaches, well vegetated
dunes, and tidal marshes) that are more resilient to the impacts of climate
change.
43. Shoreline
adaptation plans assist in educating the public about the impacts of climate change and the need to adapt. Building awareness and signalling the need
to be prepared for coastal
hazard events is an important
part of long-term resilience and
preparedness. For that reason,
shoreline adaptation plans report under
the Community and Coast priority
area of Tāruke-ā-Tāwhiri – Auckland’s Climate
Plan 2020.
44. The
Pahurehure Inlet SAP outlines how council-owned land and assets can be managed
to mitigate the impacts of coastal hazards and climate change. Implementation
of the plans will increase resilience by reducing exposure
and vulnerability of assets in hazards
zones.
45. Greenhouse gas emissions are not
directly considered within the plan, which focuses on the strategic goal of adapting the shoreline to build long-term resilience.

Council group impacts and views
46. Considering
the broad extent of council-owned coastal land and assets and the non-
statutory nature of the shoreline
adaptation plans, implementation will be a
collaborative effort across
council departments. The project team has worked in partnership with
relevant departments to co-develop the Pahurehure Inlet Shoreline Adaptation
Plan.
47. Strategies
will be considered and integrated
into all relevant council plans and documents including reserve
management plans, regional parks management plans, open space network plans and asset
management plans. This will support
associated decision making, such as landowner and leasehold approvals.
48. Shoreline
adaptation strategies will be integrated into all relevant council strategic
and targeted asset management plans to inform appropriate outcomes in the
maintenance and renewals work programmes. For example, assets that provide a
coastal defence or amenity function will be considered through council’s
coastal assets renewals programme.
49. The completion of the 20 shoreline adaptation plans will confirm
regionally consistent themes, challenges and opportunities. This will inform
the development of strategic recommendations around prioritisation, approach
and funding decisions to support implementation.

Local impacts and local board views
50. Initial
engagement with the Manurewa Local Board began in March 2023 through workshop sessions
to inform the planning for community
engagement. Follow-up workshops were held in late 2023 to provide
an update on what was heard through engagement. In March 2024
workshops were held to seek feedback and direction on the development of
adaptation strategies. In discussion
with board members at engagement
events, the board sought that:
· engagement was undertaken with local iwi and key community groups
and their views and the local information they hold was considered in the
development of the Pahurehure Inlet SAP
· aspirations and needs for the community and wider coastal users for
boat and coastal access at Weymouth were represented in the plan’s
development.
51. Community objectives and area specific feedback confirmed the value of
coastal walkways, parks and boat launching facilities and this has been
reflected in the choice of strategies for stretches 27 (Weymouth Wharf) and 29
(Keith Park) where hold the line is identified to maintain facilities and uses
over short and medium timeframes.

Māori impact statement
52. The
wellbeing of tāngata whenua and the ecosystems that support them is
interlinked with the concept of ‘mai te rangi ki the whenua, mai te
whenua ki te rangi’, as it provides for the spiritual / intrinsic
connection to te taiao. Understanding inter-relationships, well-being and
interconnectedness is a fundamental part of addressing climate change and
sea-level rise, the impacts and the response.
53. As
an adaptation workstream within Te Tāruke-ā-Tāwhiri:
Auckland’s Climate Plan, the SAPs seek to respect and acknowledge te ao
Māori by giving effect to the Te Tirti o Waitangi, Kia Ora Tāmaki
Makaurau and Te Ora ō Tāmaki Makaurau frameworks and recognising and
providing for te ao Māori concepts.
54. Engagement
and collaboration with ngā hapū me ngā iwi o Tāmaki
Makaurau have sought to establish partnership with mana whenua through the
creation and implementation of SAPs under the SAP programme. The relevant
programme principles which underpin this approach are included in Attachment A.
These principles are intended to reflect those of the Te Ora ō Tāmaki
Makaurau Wellbeing Framework under which there are three dimensions of
wellbeing that form a holistic approach - Taiao (environment), Whenua (land,
earth), Tāngata (people).
55. Several
iwi expressed an interest in the Pahurehure Inlet SAP development. While the
use of statutory acknowledgement and treaty settlement documents provide a
foundation for understanding documented and statutory interest, it is noted
that Treaty Settlement processes are ongoing, and it is important to recognise
that there are unresolved claims and disputes between the Crown and
iwi/hapū. This can result in iwi who have strong affiliation or whakapapa
to an area not holding a Statutory Acknowledgement. However, the SAP programme includes
all iwi who respond through the engagement programme, inclusive of
overlapping iwi interests.
56. Of
note for the development of this SAP is the Manukau Harbour Claim (Wai 08). In
1985, the Waitangi Tribunal (the Tribunal) reported on a claim on behalf of the
people of the Manukau Harbour. It concerned pollution of seafood resources and
loss of surrounding land from confiscation after the New Zealand wars, and for
public works. This claim is integral in understanding the impact on the
wellbeing of those iwi and hapu who live on and around the Manukau and have
done so for centuries. This report is identified and discussed in further
detail in Attachment A - section 3.3.1.
57. For development of the Pahurehure Inlet SAP, local iwi, Ngāti
Te Ata Waiohua and Ngāti Tamaoho have been activity involved in
discussions and review of the developing adaptation strategies. Te Ākitai
Waiohua, Waikato – Tainui, Ngaati Whanaunga and Te Ahiwaru, have been
actively involved in discussion, regarding the SAP programme and the
development of the Pahurehure Inlet SAP. Values provided by those iwi
identified are included in Attachment A - section 3.0 and have been considered
through the development of the SAP.

Financial implications
58. Delivery
of the shoreline adaptation plan work programme is regionally
funded through the climate action package. No additional
funding is sought from local boards to deliver the Pahurehure Inlet Shoreline Adaptation Plan.
59. Mitigating
coastal hazards will become increasingly
expensive for Auckland and wider Aotearoa. It will not be affordable or
feasible to defend everywhere. Shoreline adaptation plans and the supporting coastal asset management
plan will ensure that coastal
projects consider the escalating
future risk of climate change
and respond in both an environmentally and economically sustainable manner.
60. No financial
investment decisions have been made
through the Pahurehure Inlet SAP. The adaptation strategies will be given effect to
across relevant council decision-making. This includes the future management,
maintenance and renewal of council assets and land located along the coast
through existing work programmes and associated budgets. Over time, this will
result in cost savings as assets are moved out of coastal hazard areas and incur less damage due to coastal erosion
and flooding.
61. Once all shoreline adaptation plans across Auckland are completed, a
regional funding prioritisation approach will be
developed. The framework and process for undertaking this exercise will need to be agreed with the Governing Body.
This will assist in budgetary
requirements and support an
equitable approach for areas where managed realignment or other major coastal works
have been recommended.

Risks and mitigations
62. The risks and mitigations associated with the local boards endorsing the Pahurehure Inlet
Shoreline Adaptation Plan are outlined in Table 4 below:
Table 4: Risk Identification and mitigations
|
Main
Risk
|
Comments and risk management strategies
|
|
Coastal asset
decisions are at risk of being made on an ad-hoc basis and may not adequately consider the
escalating risk
of climate change.
|
The Pahurehure Inlet SAP including
implementation will require multiple departments across council to continue
to work together. As a strategic document,
each shoreline adaptation plan provides a coordinated and holistic approach
to council owned land and assets supporting, alongside other relevant council
policies and regulatory mechanisms, the clear and consistent consideration of
the escalating risk of climate change in relation to coastal hazards.
|
|
Potential
opposition to the proposed
shoreline adaptation plan strategies (noting
a high level of public
interest in council management
of assets in response to climate
change and natural hazard risk).
|
The
development of the Pahurehure Inlet SAP has been undertaken in partnership
with local iwi and includes extensive engagement with
the local community, wider
public and infrastructure providers.
These SAPs
remain living documents, revisions to the SAP can be advanced to respond to
further engagement with iwi and communities.
|
|
Due to uncertainty in emission reductions, coastal hazards may increase in frequency and intensity earlier than
expected.
|
Shoreline adaptation plans have been developed using a conservative, worst-case climate change scenario in
the long term. Further the SAPs
are adaptive and advancement to the
next timeframe can be considered ahead of the indicative timeframe identified
(20/60/100 years).
|
|
As multiple
teams are required to work together to
implement the SAP, there is
potential that the SAP is not applied across all business areas.
|
The project team have worked
collaboratively with departments across
council to develop the SAPs and
will maintain relationships to support implementation.
A
governance group oversees the development and implementation of the SAP work
program and also support strategic relationships.

Next steps
63. Once the Pahurehure Inlet Shoreline Adaptation Plan has been endorsed by the Manurewa, Franklin and Papakura Local
Boards, staff will present the Pahurehure Inlet Shoreline Adaptation
Plan to the Planning, Environment
and Parks Committee for approval.
64. Once approved, the
Pahurehure Inlet Shoreline Adaptation Plan will be released to the public and
to stakeholders across Auckland Council. The adaptation strategies will then be
integrated into key council plans for regional and local implementation.
