“Takahia mai ra
Te tupuna whenua o Aorere
Ka rere taku reo tongi
Mai i Mārahau ki Wainui
Whakatau mai, Whakatau mai”

“Traversing the ancestral lands
My voice soars and declares
From Mārahau to Wainui
Welcome, welcome.”

Our story

Project Janszoon, was the first privately-funded landscape-scale restoration project of its kind in New Zealand.
Launched in 2012, Project Janszoon and its partners removed pests and weeds, returned native birds, educated young people and inspired a culture of care for the Abel Tasman National Park.

THE LEGACY CONTINUES

In July 2026, Project Janszoon concluded its 14-year journey, entrusting its work to the Department of Conservation, mana whenua and the community-led Abel Tasman Birdsong Trust for long-term management under the Tomorrow Accord. Leaving a legacy of inspired youth, flourishing native wildlife, noisy birdsong, and ridgelines freed from the spread of wilding conifers.
Together, we helped heal the mauri of this extraordinary place.

our work

Project Janszoon is a story about when philanthropists don’t just write a cheque but commit to make real change that will benefit generations to come. Visitors to the Abel Tasman now see kàkā along the coast, whio and pateke in the rivers, robin are regularly spotted near the beaches for the first time in decades. The wilding pines have been dealt to, volunteers keep the gorse and other weeds at bay on the beaches, and natives like mistletoe and rata are making a comeback in the forests.

Predator Control

A comprehensive predator control programme has given native birds and plants a chance to thrive.

A blueprint for conservation

Project Janszoon was launched with the generous support of New Zealand couple Neal and Annette Plowman, who went on to establish the $200 million philanthropic NEXT Foundation. The project’s influence has extended far beyond Abel Tasman National Park with the model of collaborative conservation partnerships now replicated around Aotearoa.
