The Royal New Zealand Navy has discovered a third fishing vessel with illegal catch in the Southern Ocean.
Foreign Minister Murray McCully said this afternoon that the HMNZS Wellington had intercepted a ship called the Yongding to the west of the Ross Sea near Antarctica.
It was believed to be linked to two other fishing vessels which were intercepted by the navy yesterday, the Songhua and the Kunlun.
Defence Force officials have gathered photographic evidence of the ships using banned fishing methods.
The Songhua and the Kunlun vessels were also on an illegal fishing blacklist set up by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
