The Navy has rejected suggestions one of its vessels ordered a yacht to leave safe anchorage in Antarctica last year.
The Beserk sank in February last year killing three people on board, after dropping off Norwegian adventurer Jarle Andhoey who was trying to reach the South Pole on quad bikes.
Mr Andhoey is making a second unauthorised attempt to find traces of the yacht.
The Norwegian Broadcasting Corporation has reported he is questioning why the Berserk left its safe haven last year and activated its emergency beacon from open sea.
The Navy's HMNZS Wellington was in the area and had contact with the yacht the day before it sank.
The Navy says its communications with the Berserk were only to advise on weather conditions and at no time did the ship order the yacht to leave its safe haven.
