Greater Wellington Regional Council has filed criminal charges against Wellington City Council and Tiaki Wai under the Resource Management Act. The charges follow a catastrophic failure at the Moa Point Wastewater Treatment Plant in February 2026, which resulted in more than 14 billion litres of untreated sewage being discharged into the sea.
Both organisations face 10 charges each, with each charge carrying a maximum fine of $10 million if they are convicted. The total potential fines for each entity could reach $100 million. The charges relate to two periods: alleged unlawful discharges between October 2025 and January 2026, and subsequent discharges following the plant failure in early February 2026.
Tiaki Wai, which was formerly Wellington Water, is facing the charges because Wellington Water amalgamated into the new entity in July. While the French multinational Veolia operated the plant, it has not been charged.
