The Kaituna River Re-diversion and Maketū Estuary Enhancement Project was established to significantly increase the volume of freshwater flowing from the Kaituna River into Te Awa o Ngātoroirangi/Maketū Estuary and re-create 20ha of wetland.

The project sought to address the long-standing negative effects of the 1956 Kaituna Cut and associated works on the health of the estuary and the local community. Re-diverting the rivers flow would restore freshwater connections in the upper estuary, stop the process of sand infilling the lower estuary, and significantly improve the ecological health of the middle and upper estuary.

Along with the re-creation of 20ha of wetland and increased opportunities for public access, the project would help to make the estuary healthier for people to swim and fish in.

An Integrated Resource Recovery (IRR) strategy was developed for the Courtice Water Pollution Control Plant and was a first step towards the sustainability of this 68.2 MLD plant.
