Hikurangi Flood Management Scheme is located north of Whangarei and is drained by the Wairua River. The scheme provides flood protection and flood management to about 5,600 hectares of farmland.
A system of earth banks along the length of the Wairua River help to confine floodwater in the river channel and away from farmland. If the rivers continue to rise beyond a set level, the water spills over the banks through specially constructed spillways into confined areas of land known as pockets.
There are seven pockets which have been designed to accept floodwater flows. Water is held in these pockets until the river level drops sufficiently for pumping stations located within each pocket of land to then pump the water from the flooded areas back into the river.
We obtained a new resource consent for the Scheme, with a 35 year term, in May 2010.

Hikurangi Flood Management Scheme Management Plans
The Hikurangi Flood Management Scheme Management Plan (SMP) and the Flood Riparian and Ox-Bow/Cut-off Channel Management Plan (ROBMP) set out the operating and management procedures for the Hikurangi Flood Management Scheme as required by the resource consents.
The Fishery Management Plan is also a condition of the consent and recognises the cultural significance of the traditional tuna fishery to Ngati Hau.
Our Long Term Plan (LTP) 2012 -2022 describes how we will manage and operate the Scheme and focuses on the key areas:
- undertaking works to fulfill consent conditions
- replacement of pumps
- repayment of Scheme debt.
