Reached via a permanent causeway through the mangroves, this 5-hectare island provides a haven for the North Island brown kiwi and other native birds, as well as a pleasant picnic spot for their nonfeathered admirers. It has a visitor centre, kayaks for rent, and after-dark walks to spy kiwi in the wild (per person $35) can also be arranged. You've got around a 50% chance of seeing a kiwi, and booking ahead is essential.
