HMNZS Puriri (T02) was a coastal cargo ship which was requisitioned by the Royal New Zealand Navy (RNZN) and converted into a minesweeper.

She was one of four ships requisitioned as a consequence of the Orion's minefield and the loss of the ocean liner Niagara, the others being Matai, Gale and Rata.

On 27 November 1940, Puriri put to sea urgently to assist the cruiser HMNZS Achilles in the search for the raiders Orion and Komet, which had sunk the liner Rangitane.

On 13 May 1941, the launch Rawea attached a buoy to a German mine that had been caught in a fishing net eight miles (13 km) north-east of Bream Head.

The explosion caused the ship to immediately sink at 35°46′15″S 174°43′00″E / 35.77083°S 174.71667°E / -35.77083; 174.71667 and now lies at a depth of 98 metres (322 ft).
