Within Mate Mate Reserve reforestation and preservation interventions have been carried out over an area of 1,870,625 square metres, and 2,993,000 kg of CO2 emissions have been offset.
Before humans arrived there, Mate Mate was a rainforest. Since 1890, pioneers who landed in New Zealand destroyed most of what is today the Reserve to build a farm. Deforestation continued until the 1980s. However, since 1990 the then-landowner began fostering the recovery of the original vegetation by reintegrating wild species and excluding grazing livestock from the area. This process was undertaken to restore the wild fauna's ideal habitat. Such animals include several bird species, such as the kiwi, the national symbol of modern New Zealand.
The reforestation process has reduced the risk of flooding and improved the quality of the available potable water by reducing sediments and polluting factors.
Apiculture for honey production (Manuka quality) represents an important form of development in the region of Taranaki. The honey produced is exported also because of its famous therapeutic qualities.
