Rangitāiki River Floodway and Spillway project

The Rangitāiki River Floodway and Spillway is a multi-stage project designed to take pressure off the Rangitāiki River in a flood event, by diverting some of its flow, via a spillway, into near-by farmland between stopbanks (known as the floodway) and out the Rangitāiki River mouth at Thornton. This project involved increasing the floodway’s capacity and upgrading the existing spillway to provide more assurance during a flood event.
