What is a whaitua?

·  Whaitua is a Māori word for space or catchment.

·  Whaitua is a geographical area with hills, mountains, valleys and waterways. Rain falls on earth and then flows over the landscape finding its way through the soil or streams feeding the rivers, lakes, wetlands, freshwater aquifers and the sea\harbour.

·  Catchments are different from one another in size, shape, features and drainage patterns.

How far does Whaitua te Whanganui-a-Tara extend?

·  The boundary of this catchment extends to Upper Hutt in the north, Wellington in the south, Wainuiomata in the east and Makara\Öhāriu in the west.

·  Whaitua Te Whanganui-a-Tara includes several smaller catchment areas such as  Wainuiomata and Orongorongo, Southern coast (suburbs such as Owhiro, Island and Houghton Bays), Western coast (Makara\Öhāriu), and Wellington Harbour stream catchments like Kaiwharawhara, Kumutoto and Korokoro.

Which are the important rivers and streams that flow through these catchments?

·  Wellington Harbour has many streams flowing into it and the main ones are Kaiwharawhara Stream, Ngauranga Stream, Korokoro Stream and Waiwhetu Stream.

·  Wainuiomata River and Orongorongo River are the two main waterways over the eastern hills of the Hutt valley which drain to the south coast

·  There are three main streams -- Makara Stream, Karori Stream and Owhiro Stream -- that flow through the Southern and Western coast catchment.

There are many other streams within the catchment that flow into the harbour or feed the larger rivers and streams, but they are hidden from view for most of their length as they have been piped underground.

Is there a problem with the quality of water in our rivers and streams?

·  The communities of the Whaitua are united with, depend on and have responsibility for the waters of Whaitua Te Whanganui-a-Tara, the health of which is vital to the health and well-being of its people and all the species that lives within it.

·  Due rapid population growth over the past 150 years, the water of Whaitua te Whanganui-a-Tara is under pressure. As the water flows over the landscape it finds its way into streams and down into the soil, eventually feeding the rivers, lakes aquifers and wetlands. 

·  Issues such as stormwater and sewage discharges, and other land use activities greatly affect the health of water in our catchment.

·  Against the backdrop of increasing demand on land for housing and agriculture, we observe our streams and rivers bearing the brunt of the pressure.

·  Metal contaminants such zinc, copper and fine sediment end up in waterways during rainfall through storm water drains. These are harmful for the ecosystem.

·  Faecal contamination from livestock, sewage overflows and runoff from landfills are damaging our ecosystem and degrades the quality of water in the catchment and its ability to sustain life.

·  When the water is healthy, we all will be healthy. It’s all about respecting and caring for our water, our taonga. Water is a gift we need to protect  and enhance for future generations. By changing our relationship with water, we can change the health of Whaitua te Whanganui-a-Tara and all the communities it sustains.

What is the role of the committee?

·  It is clear that significant change is needed to reduce people’s impacts on water and improve the health of Whaitua te Whanganui-a-Tara.  There is an urgent need to start doing things differently.

·  The New Zealand Government has set some expectations nationally, and we need to work out what those expectations mean for Whanganui a-Tara. While there are some minimum expectations for the level of improvement set by the Government, the expectations our communities have for Whaitua te Whanganui-a-Tara are likely to be higher.  Greater Wellington needs to develop a plan for ensuring those expectations are met, including how they will be stepped towards over time.

·  This is a big change, and it needs to be developed with and owned by the community, as well as being informed by science and data. This is why Greater Wellington has established a committee of community members, mana whenua and councilors to work together on a Whaitua Implementation Programme, supported by a team of experts from our councils.


Who is on the committee?

The 17-member committee has eight community members, four representatives from mana whenua partners and one councillor from each of the three councils – Upper Hutt City, Hutt City and Wellington City – and two councillors from Greater Wellington Regional Council. Morrie Love has recently retired and his replacement will be announced soon.

What does partnership mean?

Greater Wellington Regional Council will develop and run the whaitua process in partnership with its mana whenua partners which in this rohe are Taranaki Whanui and Ngati Toa Rangatira. Mana whenua partners will determine how the whaitua will be supported in kawa, tikanga and matauranga Māori (process, practice and traditional knowledge). To support this approach Whaitua te Whanganui a Tara has elected co-chairs Louise Askin and Kara Puketapu-Dentice to lead the committee through this process.

What is the committees purpose?

Whaitua te Whanganui-a-Tara has adopted a Kawa based foundational framework to help them achieve this, aligning a principled start point with a strengths based approach.

“Kei te putake o Te Whanganui a Tara Whaitua tona mauri mana motuhake... hei oranga mo te katoa i noho ki konei”.

Whaitua Te Whanganui a Tara is a singular entity woven from the land, the waters and the communities of life they sustain. It transcends its component threads and cradles all who live within it.

…Are the guiding principles behind the committee’s obligation and responsibility to water.


What is a WIP?

The Whaitua te Whanganui-a-Tara committee will make recommendations to Greater Wellington Regional Council through a Whaitua Implementation Programme (WIP). This WIP will contain recommendations, strategies and actions which will inform plan change processes and form a programme of work to achieve the community’s objectives for water quality and quantity within the whaitua.

What is the relationship between the councils and this Whaitua committee?

The Greater Wellington Regional Council had initiated a community-led collaborative process to address a number of land and water management issues and to carry out its obligations under the National Policy Statement for Freshwater Management. The region was divided into five whaitua or catchments: Ruamāhanga, Te Awarua-o-Porirua, Te Whanagnui-a-Tara, Kapiti Coast and Wairarapa Coast.

Like the previous two whaitua committees (Ruamāhanga and te Awarua-o-Porirua), the Committee for Whaitua Te Whanganui-a-Tara, set up in November 2018, is independent of the Regional and City Councils. When the Committee finalises its Whaitua Implementation Programme (WIP). They will submit it to the Greater Wellington Regional Council for implementation.

The recommendations – for integrated management of land and water resources in the catchment -- will influence the District Plans of the City Councils and also become one of five chapters of the National Resources Plan for the Wellington Region.

What do you plan to do with my feedback?

All of the feedback and inputs you provide to the committee will help us develop a Whaitua Implementation Programme (WIP), which will set out the long-term vision for Whaitua te Whanganui-a-Tara and a range of actions and changes for creating and accelerating improvement towards that vision.

The committee and the community need to understand the concerns around water, and the values and aspirations of mana whenua and wider community. We all need to understand what it means to be a kaitiaki of water. These discussions will inform our vision for Whaitua te Whanganui-a-Tara and our relationship with its waters. We then need to understand how much change is needed in different catchments to realise our communities’ vision.

We need to recognize what is already happening to improve water, and understand how much more is needed.  We need to work together to agree the nature and pace of changes that will improve water across the whaitua towards our communities’ vision.
