The Motutapu Restoration Trust raised $30,000 from its Partners Life Dual Motutapu-Rangitoto Traverse, held last weekend.
Now in its sixth year, the multi-sport race brought 2100 competitors and their supporters to the twin islands, says Motutapu Restoration Trust communications committee chair John Eccleton.
"The Dual is the only multi-sport event operating within islands free of predator pests, which also host rare endangered native wildlife. It raises more conservation/restoration funding than any other sporting event in the country and demonstrates the perfect partnering of recreation with conservation."
The annual fundraiser helps to sustain the trust's vision of replanting a third of this 1500ha island.
Motutapu has the largest restoration project under way in New Zealand, says Eccleton.
