Storage tank ugly but necessary

A giant wastewater storage tank on Porirua City’s front door step will be ugly for the five to seven years it takes to get vegetation established. The Harbour Trust is advocating for a green roof with weeping vines on the structure to aid camouflage as fast as possible. The tank will provide a mechanism to avoid many of the current spills of raw sewage into the harbour so the Trust supports construction of the tank and has said so in a formal planning submission.

Planting progress

October 5 was a great post-rain day to get 3000 more plants into the ground by the Kenepuru Darts club.   Thanks to Ngāti Toa Rangatira, Porirua City Council and their sponsors plus the volunteers from the community who helped do the mahi.

AGM and a new chairperson

The Trust held its annual general meeting this month and reflected on a busy year.  Two items stood out:   The decision in June to formally cease the old trust and transfer its assets to the new Te Awarua-o-Porirua Harbour and Catchments Community Trust.  In the same month, the Trust’s Education Coordinator, Rebecca McCormack advised that she was leaving Wellington and consequently relinquishing her role after seven highly productive years.  The Trust was truly appreciative of the magnificent contribution Rebecca had made in enabling teachers and students alike to participate in the vital goal of improving the health of the harbour and catchments.  The Chair of the Trust for the last three years, Mark Neeson, also stood down at the AGM.  Mark was thanked for his significant contribution including overseeing and presenting submissions to Council plans relating to the harbour and its catchments, as well as facilitating the transfer of the original trust to a truly independent community trust.   Mark’s talents  will not be lost to the Trust, however, as he will continue serving as a trustee.   The new Chair elected at the AGM, is Michael Player.    Michael, a former public relations and communications specialist and resident of Papakowhai, has served on the old  and current trust for the last two years.   In the third change of personnel signalled at the AGM, the Trust’s secretary, Lauren James will conclude her service this month.  Trust members acknowledged her contribution over several years in helping maintain the efficient conduct of Trust administration.  Efforts to recruit a volunteer to fill the secretary role will commence immediately.

Very “on point” opinion piece by Glen McConnell about science versus the wisdom of mana whenua. He uses the  sewage overflows into our harbour and the subsequent rāhui put in place by Ngāti Toa Rangatira as a prime example. https://www.stuff.co.nz/science/300367713/western-science-isnt-keeping-you-safe-from-the-poo-in-porirua

Great news this week when Minister Megan Woods announced significant funding for the redevelopment of Porirua East.   This will overhaul the three waters systems in the area, especially replacement of the sewerage pipe in Bothamley Park that regularly overflows into the stream and contributes to ongoing degradation of the harbour.  Link to the funding announcement

June 2021

The Environment Court has delivered a withering criticism of the Gateway Partnership, builders of Transmission Gully, for damage done to the harbour.  While the penalties seem modest in the scheme of things, the Judge’s commentary confirms what locals who love and use the Inlet know – sediment has built up as a consequence of the TG build……    Environment Court slaps TG road builder with $70k fine


KPMG Review of Strategy

In February 2020 the Porirua City Council received a report from the consultancy firm KPMG entitled Te Awarua-o-Porirua Harbour and Catchment Strategy Review.  The following month the Council also received a report from Ngāti Toa entitled:  Te Awarua-o-Porirua Harbour and Catchment Strategy and Action Plan.  These reports can be found here and here.

Subsequent to receipt of the reports the CE of PCC, Wendy Walker, was made responsible for discussing with all the governance bodies (PCC, GWRC, WCC and Ngāti Toa)  a way forward from both reports.
