Wellington sewage spill: Mayoral task force called for pipe check in 2020 - did it happen?
Wednesday, 18 February 2026
Wellington Water is refusing to say if the top recommendation ‒ check critical infrastructure ‒ included in a five-year-old mayoral task force was ever done.
One part of that critical infrastructure was the 1.8km long outfall pipe from Moa Point that had an unknown issue two weeks ago causing wastewater to flood 60% of the Moa Point treatment plant, damaging 80% of equipment in it and causing raw sewage to flow off Wellington’s south coast.
“That pipe is kind of the colon of the city and it never had a colonoscopy,” said south coast resident Eugene Doyle, who was on the 2020 mayoral task force.
He said there was a behind-closed doors “revolt” among task force members as it was getting finalised to get strong recommendations included in the final report. It was clear to the task force that Wellington Water and the Wellington City Council were “sweating assets” ‒ pushing them beyond their lifespan.

Doyle, who has called for the inquiry into the Moa Point catastrophe to be held in public, said the top four recommendations of the taskforce were seemingly never fully completed. They were:
Get Wellington Water to inspect critical water assets within three years,
Task and fund Wellington Water to prioritise increased renewals investment on critical assets needing maintenance and repair,
Task and fund Wellington Water to continue to improve its asset maintenance systems and processes, and asset data collection and management,
Substantially increase the level of funding for capital funding for renewals, operational funding for planned maintenance, and operational funding for reactive maintenance to reduce the risk of asset failure.
The report was presented to the council in December 2020. Wellington Water was asked on Tuesday which of the recommendations were done, partly done and not done at all.
It said an upcoming Crown review into the sewage spill meant it could not say whether the long outfall was checked post-task force.
At a public meeting on Monday night into the Moa Point failure, Doyle got the loudest cheer when he said the mayoral task force was heard in private and but the Moa Point inquiry should be held in public.
Wellington Water chief operating officer Charles Barker and chief executive officer Pat Dougherty previously said they had technology to check only 300m of the long pipe. Doyle said “tethered drone” technology existed internationally that could go kilometres down pipes.
Resource consent documents from construction of the long outfall pipe in 1994 shows it was to be “buried in the seabed”.
Wellington mayor Andrew Little has asked Local Government Minister Simon Watts, who has ordered the Crown review, for reporting throughout the process.
“It would be my expectation that all reporting should be proactively released as appropriate,” Little said.
Watts said he was committed to “bringing as much transparency as possible to the public”.
Wellington Water has refused to talk about what caused the failure and, at Monday’s public meeting, said it did not want to jeopardise insurance.
The Insurance Council was asked if this was a legitimate concern but it responded that “we are not in a position to comment”.
