Manukau Harbour Work Programme, including options for hydrodynamic modelling


File No.: CP2015/17856






1.       To provide the Manukau Harbour Forum (the Forum) with a programme of work related to the Manukau Harbour.

2.       To provide the Forum with an update on a detailed study being undertaken to determine the feasibility of hydrodynamic modelling for the Manukau.

Executive Summary

3.       As part of its decision making on the Long-term Plan (LTP) 2015-2025, the governing body requested staff ‘identify the current, whole-of-council integrated programme of work related to the Manukau Harbour’, along with recommendations for the future programme of work, including ‘the option of hydrodynamic modelling’ (resolution GB/2015/31). (The full wording of the resolutions is appended as Attachment A for information). It is also noted that the development of such a work programme is one of the objectives of the Forum stated in its 2013 Vision and Strategy.

4.       This report presents the operational and strategic work programme related to the Manukau Harbour to the Forum for its consideration (Attachment B). The Forum is asked to note that the future work programme will be similar consisting of a mix of projects with the addition of a scoping study to determine the feasibility of any future hydrodynamic modelling project for the Manukau.



That the Manukau Harbour Forum:

a)      Notes the current projects of relevance to the Manukau Harbour.

b)      Notes that regional funding has been committed to fund a scoping and feasibility study for hydrodynamic modelling in the Manukau Harbour to be completed this financial year.

c)      Notes that options for the implementation of hydrodynamic modelling will be presented following the completion of the scoping study, and a review of conclusions from that study.



Work Programme

5.       The only agreed vison and strategy for the Manukau is that recently agreed by the nine Forum member boards. As such, the Manukau Harbour Forum Vision – The Manukau Harbour is recognised and valued as a significant cultural, ecological social and economic treasure/taonga – has provided a framework for the development of the work programme. Operational and strategic policy projects of relevance to the Manukau have been noted against the four outcome areas (cultural, economic, ecological and social) included in the vision statement.

6.       The governing body requested the ‘whole-of-Council integrated programme of work related to the Manukau. Although the attached work programme includes a number of projects relevant to the Manukau, it should not be considered an integrated programme of work. Rather, the projects noted in the attached work programme have been developed separately over time to deliver on a number of different Council outcomes, but also have relevance to the Manukau Harbour catchment

7.       The governing body resolution to identify projects ‘relevant’ to the Manukau Harbour allowed for the development of a wide-ranging work programme, including both operational and strategic policy projects. Operational projects include restoration activity in local parks and reserves neighbouring the Manukau, as well as along streams that feed the Manukau. The work programme also includes activity within the wider harbour catchment such as water quality monitoring.

8.       The strategic programme of work relevant to the Manukau includes an upcoming state and trends report on the Manukau Harbour and its catchments, drawing on information collected as part of the regional state of the environment monitoring programme. A review is also being undertaken of the 1990 Manukau Harbour Action Plan to identify what actions from that plan have been completed, or incorporated into existing departmental work programmes.

9.       The work programme includes projects funded at a regional level and through local boards’ locally driven initiatives (LDI) budgets. It also references work programmes managed by Council Controlled Organisations. In summary, there are planned for investments in several activity areas noted under the following headings in the attached spreadsheet;

·         Strategy and Policy;

·         Water Quality;

·         Ecological Restoration;

·         Amenity;

·         Monitoring, and

·         Renewals.

Future Work Programme

10.     The current work programme identifies a range of projects supporting cultural, economic, ecological and social outcomes. It is recommended that in developing their annual work programmes that Forum member boards continue to have regard to projects that impact on the Manukau Harbour.

11.     Council staff recommend that any future programme of work for the Manukau Harbour include the development of a strategic plan. This plan would provide for the development of the integrated programme of work requested by the governing body and referred to in the Forum’s vision and strategy.

12.     At a regional level, there is no up to date strategic plan for the Manukau Harbour. The last action plan for the Manukau Harbour was released in 1990 and was developed over several years, with extensive research programmes undertaken to inform the action plan. Early assessments of this document have determined that it is focused on discharges, with less commentary on reducing sediment entering the Manukau. It is likely that the full review of the 1990 Action Plan will illustrate the need for an updated plan to be prepared for the Manukau Harbour.

13.     At present, the Council’s plan for implementing the National Policy Statement for Freshwater Management (NPSFM) has not yet been finalised.[1]  However, in principle, the NPSFM requirement to identify community uses and values for waterways (which are then translated into water quality and quantity limits and targets) requires consideration of the marine receiving environment, as well as an understanding of the contaminant sources.  The Manukau Harbour is a “Freshwater Management Unit” (FMU) for the purposes of the NPSFM and should be considered a possible tool for integrated planning and action to address the water quality issues in the Manukau. 

14.     Indeed, while officers have recommended a strategic plan for the Manukau, the preference of the Forum is for hydrodynamic modelling to take place either concurrently with the development of a strategic plan, or to be undertaken independently of a plan.

15.     As such, it is recommended that the future programme of work for the Manukau remain similar to that illustrated in Attachment B, with the addition of a hydrodynamic modelling scoping study.

Hydrodynamic Modelling

16.     The concept of hydrodynamic modelling was first presented to the Forum in November 2014 as a key initiative in developing a strategic plan for the Manukau. Hydrodynamic modelling can provide predictions in water levels, tidal currents and waves across the harbour (2 dimensions) but also from the seabed to the watersurface (3 dimensions). This third dimension component is very important to adequately model the complex movement of sediment and contaminants within the harbour (vertical mixing in the water column and resuspension). A copy of that presentation is appended as Attachment C, with additional detailed information on hydrodynamic modelling appended as Attachment D.

17.     Since that presentation, the Forum’s member boards have consistently advocated for hydrodynamic modelling as a means to understand where sediment and other sources of contamination are entering the Manukau, and where it goes.  Data on sediment and other contaminant sources will be required for the model to function.  In itself this will be useful information, but the implications are not yet understood.

18.     The input data on sediment and other contaminants, together with the outputs of a hydrodynamic model would assist the design and delivery of targeted interventions to reduce sediment and contamination. There is no hydrodynamic modelling that covers the whole of the Manukau and most studies are more than 10 years old.

19.     A detailed feasibility study is needed to determine if hydrodynamic modelling will meet the above expectations along with the costs and potential project staging. The scoping study will identify the data requirements for the model and assess that against currently available data.  This will help determine staging, costs and likely effectiveness of the model. It is therefore recommended that the scoping study be completed at a cost of $20,000, prior to any further work, to identify funding sources for this modelling work.

20.     The scoping study will be funded regionally through budgets held by the Stormwater, Environmental Services, Research and Evaluations Unit (RIMU), and Natural Environment and Strategy units.

21.     The scoping study is a critical and informative prerequisite to the development of a hydrodynamic model for the Manukau Harbour.  Given the significant investment and budget re-prioritisation that would be required to fund the model’s development, a thorough business case needs to be established.

22.     It is recommended that the Forum note that a scoping and feasilbility study will be completed, and that options to progress the modelling will be developed following completion of that study.


Local Board views and implications

23.     The work programme includes projects funded by local boards through their LDI budgets. These projects will be in scope if a reprioritisation of budget is required to fund hydrodynamic modelling.

Māori impact statement

24.     No consultation with Maori was undertaken for the purposes of this report. Consultation and engagement with Maori is undertaken on specific projects within the work programme where required. In addition, mana whenua noted support for work to improve water quality in the Manukau as part of their submissions on the LTP.

25.     Any future programme of work for the Manukau, including the development of a strategic plan, would need to have regard to pending Tiriti ō Waitangi discussions with Manukau Harbour mana whenua.

26.     The Forum has agreed to meet with mana whenua up to three times per year. Depending on the scheduling of the first hui, there may be an opportunity to discuss this work programme and the proposed hydrodynamic modelling with iwi at that hui.


27.     The outcomes of the scoping study will be discussed with the Forum prior to any decision making on funding for hydrodynamic modelling.

28.     As per the resolutions of the governing body, feedback received at this meeting will be incorporated into a report on this work programme to be presented to the Regional Strategy and Policy Committee (RSPC). As no new funding is available to support hydrodynamic modelling, the report to RSPC will need to provide recommendations on the re-prioritisation of this work programme to identify funding for the modelling work.

29.     It is noted that the RSPC is not able to reprioritise projects funded through local boards’ LDI budgets and projects taking place on parks in order to fund future hydrodynamic modelling.
