The Antipodes Island group is a complex of volcanic cones and vents. Sheer cliffs rise to a tussock strewn plateau, and these cliffs continue beneath the waves where they support sessile (stationary) marine invertebrates in large numbers and a diverse array of seaweeds. To the south of the group the ocean drops away to a depth of 3000 m, some of the deepest waters in any New Zealand marine reserve.
Bounty/Moutere Hauriri Marine Reserve was created in 2014, at the same time as marine reserves for the Campbell Island/Motu Ihupuku and Antipodes Island/Moutere Mahue islands.
The marine reserve covers 100% of the territorial sea surrounding the islands (to 12 nautical miles). The islands themselves are protected as a Nature Reserve.
The main and by far the largest island, Antipodes Island, was named because it is nearly opposite – antipodal - to London, England. The marine reserve’s Maori name Moutere Mahue is translated as “abandoned” or “deserted” island, recognising its isolation and remoteness.
