Oneriri Station is committed to protecting and fostering the growth of indigenous forest, fauna and birdlife on the peninsula. The station is a member of the Oneriri Peninsula Landcare Group, a partnership between the four landowners that occupy the peninsula and the Northland Regional Council.
The objective is to create safe and sustainable indigenous forests that allow native flora, fauna and birds to flourish. To this end, a successful predator control program commenced in 2004 and has expanded to a network of 500 traps and 1000 bait stations reducing possums, rats, cats and mustelids to very low levels. A dramatic improvement in new forest growth is evident, along with higher levels of bird sightings. Oneriri Station is currently undertaking a joint venture with Predator Free Aotearoa to eradicate possums from peninsula.

Four full-time staff run the station: a farm manager, two shepherds and a fencer and a water technician. All staff live on the farm, every house is on a school bus route, and the area has good primary and secondary schools.
