I am very sorry that this has happened.
On 2 September 2026, the New Zealand government released a statutory review into the collapse of Wellington's Moa Point wastewater treatment plant, which failed on 4 February 2026. The review found the failure was not one mistake, but longstanding weaknesses in governance, accountability, asset management, risk management, and infrastructure resilience.
A government review found Wellington's council let known sewage-plant weaknesses persist for years. A downgrade has been proposed that would move the city out of the benchmark's top tier — it has not been applied yet.
