Stormwater and wastewater improvements for Lower Hutt

The Infrastructure Acceleration Fund (IAF) project will delver major stormwater and wastewater upgrades across central Lower Hutt. The project will strengthen flood resilience, improve the wastewater network and support the city's future growth.

From 1 July 2026, Tiaki Wai became the lead organisation responsible for delivering this project. Hutt City Council continues to work closely with Tiaki Wai, but project information and updates are now available on the Tiaki Wai website.
