Wellington sewage spill: Mayor stops short of confirming Government inquiry
Monday, 9 February 2026
Wellington mayor Andrew Little will not confirm if the Government will launch an inquiry into the Moa Point sewage treatment plant failure, saying he needs several days to consider options.
The mayor met with Prime Minister Christopher Luxon and Local Government Minister Simon Watts on Monday with calls for an independent Government inquiry.
After the meeting he would not confirm the type of inquiry discussed, he said it was agreed an independent investigation was needed and was confident it would be under way soon.
“What we agreed on was that doing something that would lead to an investigation as quickly as possible is preferable, but on the basis it has the right expertise and the right powers to get the right information.”

Wellington sewage spill: Is it me, or does something stink here?
A ministerial inquiry was his preference, he said: it would be independent, have the right expertise and have the power to get information.
Such inquiries rely on witnesses’ co-operation and are initiated by the minister responsible for the relevant portfolios ‒ in this case, Watts.
Last Wednesday, Moa Point’s1800m long outfall pipe that sends treated wastewater deep into Cook Strait backed up, flooding the lower floor of the Moa Point plant with wastewater, tripping all fuses. South coast beaches are closed due to the danger from sewage.
Little told The Post earlier today the idea the sludge plant’s only backup was to discharge completely untreated sewage within metres offshore was “out of this world, out of date and unacceptable”.
Little’s interview with The Post came instead of a planned a sit-down interview with Wellington Water chief executive Pat Dougherty, who was instructed by Little to stop talking to media after claims warning signs were missed in the lead- up to the event.
“It doesn't help to speculate about that stuff at this point, until there's a genuinely independent investigation,” Little said in response.
“Otherwise it looks like parties are potentially looking to their own self interest and managing the information that goes out, as opposed to ensuring that there's a genuinely independent investigation.”
He said the council was responsible for the sewage plant as its owner and it was important the council stepped up. There had been no indication from Government about financial support for remediation.
“Obviously, we rely on Wellington Water as the operator to continue doing their work to get the plant fixed up, and they'll advise us on what remediation is required.”
He said it was important for the inquiry to begin as soon as possible, so the cause of the spill ‒ and any design flaws ‒ could be identified while repairs were still under way, ensuring “we don't repeat the mistakes of the past”.
“We need to know that any backup or any fail safe is, as the name suggests, safe.”
Little said the council was required to have all its assets in a functioning condition to transfer to the new water entity, Tiaki Wai, on July 1.
“That's the other pressure on us … until we have some certainty about how quickly it can be fixed, we don't know whether that even is going to happen at that time.”
Watts said the impact of the spill on local communities and Wellingtonians was “completely unacceptable”.
“It's pretty clear that this is really unsatisfactory. We need answers in terms of how a critical asset such as this could have failed in such a way.”
He said it reinforced to him the direction the Government was taking under Local Water Done Well.
Prime Minister Christopher Luxon said the key was to work out why such a critical piece of infrastructure failed so catastrophically.
He said New Zealand had done a poor job of managing infrastructure, with a “band-aid solution” approach in the past.
Labour local government spokesperson Tangi Utikere blamed the Government's water reforms for water infrastructure failures, saying Labour's Three Waters plan was an “excellent, fair plan for reliable water infrastructure“.
“As water infrastructure falls apart, it’s glaringly obvious the Government’s delayed and diluted water reforms are not good enough.”
