A large chunk of the land around Cape Reinga is part of the Te Paki Recreation Reserve managed by DOC. It’s public land with free access; leave the gates as you found them and don’t disturb the animals. There are 7 sq km of giant sand dunes on either side of the mouth of Te Paki Stream. Clamber up to toboggan down the dunes. During summer, Ahikaa Adventures are on hand to rent sandboards ($15).
