Major Project MAR

Managed Aquifer Recharge Trial (MAR)

The Managed Aquifer Recharge (MAR) project aims to inject water from the Waipaoa River into the Makauri aquifer for use on 3000 hectares of irrigated horticultural farmland. Once complete, the trial will show if it's possible to increase water in the aquifer with minimal impact on water quality and the environment.

The Makauri aquifer is the largest underneath the Poverty Bay Flats, extending from Kaiteratahi down to Makaraka and spanning both sides of the Waipaoa River.

The trial began in 2017, jointly funded by Council, Ministry for Primary Industries and Eastland Community Trust. During the trial 75,000m3 of water was successfully injected into the aquifer.


The Provincial Growth Fund has granted $542,000 towards it and the Eastland Community Trust will contribute a further $448,500. Combined with council funding of $160,000 in the Long Term Plan, stage 2 of the trial is now fully-funded.
