The kākā is one of New Zealand’s native parrots. Despite being hammered by predators such as cats, rats and stoats, these inquisitive birds are making a comeback on predator-free offshore islands.

This video shows how the removal of rats from Te Hauturu-o-Toi/Little Barrier Island has cleared the way for tuatara as well as many other native species to thrive in the kind of place New Zealand once was.

Hihi are one of NZ's rarest birds, and became extinct on the mainland over a hundred years ago. Luckily, the island of Te Hauturu-o-Toi/Little Barrier remained free from most predators, and has been a lifeboat for their survival.

Weeds in New Zealand are sometimes underrated as a pest. On Te Hauturu-o-Toi/Little Barrier Island weeding can mean some extreme antics, including abseiling off a cliff to get inaccessible weeds.

Te Hauturu-o-Toi or Little Barrier Island, near Auckland, has been described as the ‘jewel in the crown’ of New Zealand’s protected islands. Watch this video to see why it’s so special.
