The Tūhua Marine Reserve covers about 3 square nautical miles across the island’s northern coastline and extends from the high tide mark onshore to one nautical mile offshore. The reserve includes about five km of coastline from Tumutu Point east to Turanganui Point.
The eastern and western reserve boundaries, Turanginui Point and Tumutu Point, are marked by a pair of yellow triangles on the cliffs. The triangles line up when seen from the boundary.
The seaward boundary is located as described on the map above and coordinates below.
The island is privately owned. Strict quarantine rules apply. Landing is only permitted at Opo / South East Bay when the caretaker is present. Otherwise all landing prohibited.
