Our Vision

Restored biodiversity from the mountain to the sea.


Our Work

Our committed team has been working to restore biodiversity from the Mountain to the Sea together with the amazing support of our local community.

The Karioi project focus encompasses Karioi and its coastal escarpments and forest, wetlands, freshwater and marine habitats and communities to the north and south of the mountain from Whaingaroa Harbour to Aotea Harbour.

Seabird Monitoring Program

Our seabird monitoring program identifies key seabird breeding sites and targets predator control in these areas. Our monitoring program aims to give seabirds the best chance at success by protecting active breeding burrows and monitoring nesting success.

Predator Control

As well as managing large-scale stoat control on over 2,000 hectares – with more than 45 km of trapping lines – we are also implementing intensive predator control of stoats, rats and feral cats around key Oi habitat to protect breeding sites along the Karioi coastline. We currently have over 800 traps deployed across Karioi Maunga and the Whaingaroa coastline.


As a significant proportion of Karioi Maunga and adjacent coastline and landscape is privately owned, active and willing landowner participation is vital to providing effective predator control.   We aim to work with all willing landowners around Karioi and the Whaingaroa community through our “Backyard Programme”.

For landowners that want to participate in the project, we can provide advice, training, and extra hands through our network of volunteer supporters to help with predator control.


Our vision is that through the Karioi project people will develop an enhanced curiosity of the natural world and a love for nature. We hope this curiosity and love will motivate them to take action in caring for the environment and inspire them to engage in environmental care.

The Karioi project provides an educational programme centered on the diverse ecosystems of Mt Karioi with a focus on water, land and sea including coastal forest, freshwater streams, marine rocky shore, and inter-tidal ecosystems. We actively encourage the involvement of all families and individuals - including children and youth through our workshops and educational programmes, Karioi Kids and Karioi Rangers, and by working together with our local schools. Our activities include trap-checking, monitoring traplines, workshops, community events, and camps in which people of all ages are welcome.

Karioi Kids and Rangers

We run an after school environmental program in Term 1 and 4 for Karioi Kids (7-8 years) and Karioi Rangers Term 1 to 4 (9-13 years). 

Community Education

Working days, trap- checking, monitoring, workshops, community events and camps are often inclusive of all ages.

School Programmes

If you are interested in your school visiting or in doing predator control at your school, then please contact us. We can provide educational presentations and also fun and adventurous experiences for young and old on Karioi.
