Wellington Beaches Reopen with Caution After Sewage Spill

Wellington residents can now return to many of the city’s southern beaches, but are urged to check water quality updates before swimming, following a major sewage leak earlier this month. The move comes after nearly three weeks of monitoring the impact of the untreated sewage discharged into the Cook Strait.

Sewage Spill Details

The city’s southern coast has been off-limits since February 4th, when the Moa Point Wastewater Treatment Plant failed catastrophically, releasing approximately 70 million litres of untreated sewage into the sea daily. A rāhui was in place from Ōwhiro Bay to Breaker Bay, restricting activities in and around the water.

Current Status and Restrictions

As of Wednesday, February 25, 2026, the public health advice has changed, allowing people to swim near the shore from Ōwhiro Bay to Breaker Bay. However, Tarakena Bay remains closed due to its proximity to the short outfall pipe. Daily water sampling at 23 sites along the coast has shown acceptable bacterial levels for safe swimming near the shore during dry weather, excluding periods immediately following rainfall.

Mayor Little’s Announcement and Reassurance

Wellington Mayor Andrew Little announced the change in policy, stating that the city and regional councils, Wellington Water, and public health officials are now able to assess the level of risk. He emphasized that even as testing results show little to no contamination in many areas, a risk remains. To demonstrate confidence in the water quality, Mayor Little took a swim at Lyall Bay.

“We have to be realistic and practical about what we’re asking people to do,” Little said. “Conditions can change rapidly…you make your own decision about whether you want to go onto the beach and have a swim in the sea.”

Where to Find Updated Information

Residents are strongly encouraged to check the LAWA (Land, Air, Water Aotearoa) website for the latest water quality information and advice before visiting beaches. The website provides daily updates on the risk factors and suitability for swimming.

Iwi Concerns and Ongoing Review

While public health advice supports a cautious return to the beaches, iwi representatives maintain concerns about the overall health of the sea. The government has also launched an independent review into the Moa Point treatment plant failure to determine the cause and prevent future incidents.

Key Takeaways

• Many southern Wellington beaches are now open for swimming, but with caution.
• Tarakena Bay remains closed due to its proximity to the sewage outfall.
• Residents should check the LAWA website for up-to-date water quality information.
• A risk remains, and individuals should make informed decisions about swimming.
