Waikato Waters Launches: Six Councils Begin Water Merger

Waikato Waters, a new council-controlled organisation, officially began operations on 1 July 2026, taking over water and wastewater services on behalf of six Waikato District Councils. The organisation was established jointly by Hauraki, Matamata-Piako, Otorohanga, South Waikato, Waipa and Waitomo District Councils, with interim chief executive Neil Brennan at the helm. Hauraki District Mayor Toby Adams spoke on behalf of the councils, saying the shared approach would deliver better outcomes than each council could achieve on its own.

The transition is happening in stages rather than all at once. Waitomo, South Waikato and Waipā district councils transferred their water services to Waikato Waters today, Matamata-Piako District Council will follow on 1 October 2026, and Hauraki and Ōtorohanga district councils will join on 1 July 2027. Once all six councils have transitioned, Waikato Waters will serve around 170,000 people from Marokopa to Whiritoa, supplying an average of 27 million litres of water a day in its early stages.

For residents, little will change immediately. Customers will keep paying for water through their councils and reporting issues the same way as before, with Waikato Waters eventually developing its own billing and customer service systems. Most operational staff have transferred across from council roles and will continue doing the same work, just under new branding. Brennan says retaining this local knowledge is one of the organisation’s key strengths.

Looking ahead, Waikato Waters has inherited 24 active infrastructure projects and plans to start 18 more in its first year, backed by an $82 million capital investment programme. This includes new water storage reservoirs, treatment plant upgrades and the Cambridge Wastewater Treatment Plant. The company will also spend its first year developing a 10-year Water Services Strategy for the region, as part of the broader local government reform occurring in response to ageing infrastructure and rising costs across New Zealand’s water sector.
