Wellington's Coastline Choked by Sewage Outflow
19 Feb
Summary
- Millions of litres of sewage enter the ocean daily.
- A collapsed plant causes pollution near marine reserves.
- Public health warnings and environmental damage reported.

Wellington, New Zealand's capital, is grappling with a significant environmental disaster following the catastrophic collapse of its wastewater treatment plant on February 4th. For over two weeks, millions of litres of raw or partially screened sewage have been discharged daily into the ocean along the city's south coast, impacting pristine reefs and a marine reserve. This ongoing pollution has resulted in abandoned beaches, public health warnings, and disturbing scenes of wildlife, such as seagulls, consuming human waste.
The crisis is posing a serious threat to marine ecosystems, including the habitats of vulnerable species like the little blue penguin. Residents are concerned about the long-term environmental damage and the disruption to those who rely on the coast for recreation and income. Public meetings have seen hundreds demanding answers and accountability from city officials and Wellington Water, the utility responsible.
Investigations are underway to understand the cause of the plant's failure, which reportedly destroyed 80% of its equipment due to an electrical failure. While most sewage is now being screened and discharged further offshore, the flow into the sea continues. Authorities have warned that a complete resolution could take several months, raising further concerns about prolonged environmental impact and potential underinvestment in critical infrastructure.
Local iwi (tribes) have expressed deep anguish, highlighting their long-standing opposition to wastewater discharge into the ocean, which they consider a vital source of sustenance. Marine biologists warn of potential kelp die-offs and harm to various marine life within the Taputeranga Marine Reserve. The situation underscores a broader national debate in New Zealand about water management and infrastructure investment.
