Local Government Reform and Rates Cap

The story so far

The Government passed its Local Water Done Well legislation in August 2025, replacing the previous Three Waters regime, after councils had begun deciding how to deliver water services. Ruapehu voted against a four-council water entity and chose to partner with Whanganui, and Whanganui agreed to form a joint entity.^{10, 15 Jul 2025; 19 Aug 2025} Councils and mayors raised concerns about costs. Ruapehu councillors upheld their decision despite the mayor's warning that household bills would rise by nearly $1000 a year, and South Wairarapa asked for financial help for small councils.^{28 Jul 2025; 14 Aug 2025} In late 2025 the Government announced a rates cap of 2% to 4% a year, due to start in January 2027, and began work on regional council reform. Mayors, including Auckland's, warned the cap could force service cuts and affect major projects, while a Masterton ratepayers group welcomed it.^{1, 2, 3 Dec 2025} By mid-2026 councils were required to submit amalgamation proposals through the Government's Head Start process. Proposals and disputes emerged across Waikato, Wellington, Canterbury and the South Island, and Ruapehu and Tararua councils voted against taking part.^{29, 30 Jul; 4, 5, 6, 13 Aug} The Government confirmed the 2% to 4% cap in August 2026 but moved its start to 2029.^{25 Aug}
