Biosecurity and Eco-Restoration Experts on Waiheke Island and across the Inner Hauraki Gulf.
Invasive pest plants and animals threaten our unique island ecosystems. Loss of biodiversity is a global problem that requires local solutions.
Our mission is to protect and sustain biodiversity in public and private lands within the inner Hauraki Gulf for future generations to enjoy.
It’s never too late to change our world. We do it every day.
Our hardworking team bring years of experience to bear on the greatest challenge of our time: loss of biodiversity. We’re results driven, with a proven record of previous successes.
We Do It Differently
What does jungle warfare have to do with modern biodiversity restoration on Waiheke Island and other islands around the Hauraki Gulf in NZ? Join former Infantry officer and owner of Free The Tree Ltd. on a pest plant patrol to find out! This light-hearted yet sincere approach to conservation shows you how a military tactic devised in World War II to defeat a foreign invader, has been adapted to defeat invasive pest plants on one of the world's only urban islands.

Biosecurity Solutions
We control pest species that threaten Aotearoa’s biodiversity—especially those red-flagged under MPI and Auckland Council’s Regional Pest Management Plan. Whether on public land or private property, we’re known for tackling high-impact invaders like Mothplant, Climbing asparagus, pest trees such as Rhamnus, and animals like rats and wasps.
As Biosecurity Warrant Holders and a trusted provider to Auckland Council, landowners, and community conservation groups, we bring credibility, legal authority, and results—wherever we work.

Eco-Restoration Services
From single species pest control to multi-year restoration plans, we help landowners and community groups protect and regenerate native ecosystems. We offer practical, science-backed advice on pest plants, pest animals, planting, and long-term site care.
We also love to plant trees—and with the right site prep and follow-up care, we make sure those trees stay in the ground and thrive. Whether you're managing a coastal block, a wetland, or a bush-clad ridge, we’ll help you make a real difference, long-term.
