Kerikeri Wastewater Treatment Plant


The Kerikeri Wastewater Plant was certified as completed on 23 October 2020. The new facility has the ability to add hundreds of new customers to the sewer network and significantly reduces the town’s reliance on septic tanks and other on-site disposal systems.  

The process of switching Kerikeri properties over to the new system was completed in May 2021. The facility will allow the Far North’s fastest growing urban centre to accommodate new residents and businesses without having to spread outwards. More than 1400 properties in central Kerikeri will benefit from the sewerage scheme.

Treatment plant stats

  • Treat 1000 cubic metres of wastewater per day (three times the capacity of the previous plant at Shepherd Road).
  • Treat waste from 1090 properties already connected to the Shepherd Road plant.
  • Add another 350 central Kerikeri properties that currently rely on septic tanks.

A further 350 to 400 new properties within the expanded reticulation network can also connect to the system. The actual capacity of the new plant will be confirmed when it has operated in both dry and wet weather flow conditions. 

The treatment plant updates the technology being used to treat Kerikeri’s wastewater emphasising efficiency, reliability and expandability.

The new connections improve quality of life, and of the local environment, by removing the need for hundreds of septic tanks.

The project supplies a long-term solution to an ongoing (medium-term) problem (full-capacity operation of existing plant).
