Reviving land and water resources for tangata whenua

GNS Science and local iwi are partnering in two new land and water restoration projects. One project is aiming to rehabilitate land impacted by geothermal development near Reporoa in the Rotorua district, and the other will improve land and water quality around Hokianga Harbour in Northland.

Our scientists will work with Tāhorakuri A1 Section 30 Trust to improve land near Reporoa that has suffered from subsidence, loss of geothermal surface features, and westward migration of the Waikato River. 

A key part of the project is developing a model which combines geoscience with mātauranga-a-hapū. It will combine geothermal, freshwater and cultural resources with economic opportunities which are based on collaboration between hapū and geothermal field operators. 

In Northland, GNS Science staff will work with Far North iwi Te Rarawa Anga Mua to build their capacity to manage and restore parts of Hokianga-Nui-a-Kupe (Hokianga Harbour). Human activity has resulted in species loss, poor water quality and damaging siltation. 

Twenty-eight marae link to the harbour and its estuaries, and local communities want to restore and regenerate the harbour’s mauri (life force). The projects have received funding from the Ministry of Business, Innovation and Employment’s Vision Mātauranga Capability Fund — Te Pūnaha Hihiko.
