Upper Hutt City Council has confirmed major changes to how water services are billed, as part of the region’s shift to the new water services entity, Tiaki Wai. From 1 July 2026, water charges will no longer appear on council rates invoices. Instead, Tiaki Wai will issue separate bills directly to property owners across the Wellington region, including Upper Hutt, Lower Hutt, Porirua, and Wellington City.
Property owners can expect their first Tiaki Wai bill in late July or early August 2026, with payment due by 1 September 2026. Bills will be issued quarterly and will cover drinking water, wastewater, and piped stormwater services. Existing rates direct debits will not transfer automatically, so customers wanting to pay by direct debit will need to set up a new arrangement with Tiaki Wai. In the first year, charges will largely mirror each council’s existing pricing structure, meaning costs may vary between different parts of the region before a more consistent regional pricing model is introduced over time.
For most water customers, day-to-day services will not change when Tiaki Wai takes over on 1 July 2026. Water assets will remain in public ownership, with Tiaki Wai collectively owned by the councils involved, including Upper Hutt City Council, Hutt City Council, and Porirua City Council, on behalf of their communities. Tiaki Wai will also absorb Wellington Water and take on responsibility for the significant infrastructure investment needed across the region, which has an estimated replacement value of almost $18 billion.
This change reflects the wider local government reform occurring across New Zealand, as councils grapple with ageing infrastructure, tighter water standards, and the financial pressure of long-term upgrades. Upper Hutt City Council says it will remain a joint owner of Tiaki Wai and will continue to represent residents through regional governance arrangements. Further details on billing, payment options, and account setup are available on the Tiaki Wai website.
