Tuhua (Mayor Island) in the eastern Bay of Plenty, is a collapsed volcano on the edge of the continental shelf.
The marine reserve surrounding it is a wonderful dive spot, with a mixture of shallow reef and deepwater environments. Warm currents bring subtropical visitors, and there are dense schools of kingfish and pink and blue maomao, among many other species.
The island has beautiful beaches and two crater lakes – one green and one black. It was settled by Maori about 600 years ago, and was fiercely defended throughout its pre-European history due to its deposits of obsidian – a rare black volcanic glass used to make cultural artefacts and weaponry.
Tuhua is now uninhabited but can be visited with permission from the Tuhua Trust Board. You can stay on the island during the summer months.
Tuhua is 35 km offshore north of Tauranga. The marine reserve covers about three square nautical miles at the northern end of the island and extends from mean high water springs mark to one nautical mile offshore. The reserve includes about five km of coastline from Tumutu Point east to Turanganui Point.
