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 2,300 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 1500 traps deployed across Karioi Maunga and the Whaingaroa coastline.


Karioi Backyard program

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”. We even have a trap library that provides traps for low to no cost for backyard trappers!

This program is strongly aligned with the Predator Free 2050 vision for New Zealand. For landowners and families that want to participate we can provide advice, training, and subsidised traps. Connect with us and we will help set you up.


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 our beautiful environment.

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 including a brand new NCEA level Maanaki Ao - Earthcare program at Raglan Area school. 

Karioi Kids and Rangers

A year-round after school environmental program run in Term 1, 2 and 4 for Karioi Kids (7-8 years) and Karioi Rangers (9-13 years). 


Community Education

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


Maanaki Oa Earthcare program

We are co-creating the Maanaki Ao programme together with Raglan Area school and Papa Taiao to deliver an environmental and outdoor education program for Year 11 to 13 students. 

Throughout the programme students participate in practical, hands-on activities in challenging physical environments and gain both NCEA Unit and Achievement Standards at Level 2 and 3.

School visits

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.
