Story from Kapi-Mana News 26 August 2014 pg 7. New group to care for our harbour. Read on-line.

The new Porirua Harbour and Catchment Joint Committee and other stakeholders went on a tour last week, to learn more about the issues facing Te Awarua o Porirua Harbour.

The committee has been set up to oversee implementation of the Porirua Harbour and Catchment Strategy and Action Plan.

The committee has the authority to ask for reports on aspects of harbour and catchment issues, strategy implementation and activities. It has yet to decide how often it meets, but all meetings will be publicised and open to the public.

The Joint Committee, chaired by PCC Councillor Bronwyn Kropp, is made up of 5 representatives from Porirua City Council, Ngati Toa Rangitira, Wellington City Council and Greater Wellington Regional Council.  Each member will report back to its respective Council or Runanga.

The first meeting (of the group was 26 August 2014). The main items on the agenda were the annual report on how the Harbour Strategy is being implemented, and highlights from the past year which include:

  • Completion of a draft Porirua Stream Mouth Enhancement Plan and a catchment-wide Sediment Reduction Plan;
  • Continued major upgrades of sewer networks;
  • Several initiatives to better inform and engage the community in contributing to a healthier harbour;
  • Ngati Toa Rangatira completed the first full fish survey of Porirua Harbour, while GOPI recorded a good increase in cockle numbers in its latest 3-yearlysurvey of the Pauatahanui Inlet.

Harbour health a concern

Rubbish on the decline, but still a blight

Photo by Fairfax: Looking down - Porirua Harbour's health has been the subject of extensive policy work, discussions and strategy meetings in the past few years.


The large amount of rubbish entering Porirua Harbour remains a concern, but the overall health is on the rise, according to a newly released 'scorecard'.

Wellington Regional Council recently completed a mapping and inter-tidal survey of the harbour as part of an action plan to improve its overall health.

The plan is part of a project adopted by Porirua and Wellington City councils, the regional council and Ngati Toa, with help from 10 other agencies.

One of them is the Porirua Harbour and Catchment Trust. Its chairman, Grant Baker, said its own state-of-the-harbour scorecard revealed several positives.

The trust's review panel looked at agency action, sedimentation, recreational usage, ecological health and waste.

"There is a perception from the regular harbour users that it is improving, giving it an overall 4/5 mark," Mr Baker said. "They say the water quality has improved and they rate their on-water experience as good.

"The feeling is that things are starting to happen, which is great."

What was not good was the rubbish, such as tyres, road cones and shopping trolleys, that are still coming from the Porirua Stream.

"It's an ongoing issue. In 2009, there were over 400 items taken out of the Onepoto Arm and in the last two years the trust and Keep Porirua Beautiful have done a clean-up there in November.

"In November we took out 172 large items, 132 of which were tyres. It's down from 260 items in 2012, but it's still too much."

The Porirua Harbour and Catchment Trust gave the agency action - help from organisations that said they would provide funding towards the harbour's health - a 3/5 mark.

Sedimentation it rated 5/5 in the Pauatahanui Inlet and 3/5 in Onepoto. Mr Baker said an increase of soft mud in the harbour, from three hectares to 20 hectares in five years, was a concern.

Further work on reducing the inflows and achieving the action plan target of 1mm per year was needed, Mr Baker said.

The scorecard's water quality marks varied.

The trust ranked the quality at Paremata Bridge 4/5, Plimmerton Beach, Karehana Bay and the water ski club on the Inlet 3/5, and 2/5 at the rowing club at Onepoto.

The Porirua Stream's health at Wall Place received a rating of 3/5, but 4/5 at Horokiri and Pauatahanui streams.

Mr Baker said the regional council's testing regime, and making the results readily available, was appreciated.

"The data is very important and it allows us to cherry pick a lot.

"What we're doing with the scorecard is setting a benchmark that we'll use every year from now on. With the work starting on Transmission Gully, we can track what effect that will have, too."

Mr Baker said the trust would do a scorecard every February.

Ngati Toa kaumatua Taku Parai said close scrutiny of the harbour by the regional council could only be good.

"Looss of significant habitat in the harbour is a problem that has affected Ngati Toa for many generations. Having access to the information provided by these surveys is empowering for iwi and the whole community to work together for positive change," he said.

Porirua Mayor Nick Leggett said stormwater and sewer upgrades, community education and the development of an estuary restoration and catchment vegetation framework were among the projects Porirua City Council was committed to.

There was a tighter earthworks policy and an erosion control plan coming, Mr Leggett said.
