A Norwegian explorer who led an unauthorised trip to Antarctica last year says he is now back there - again without permission - to find out how three of his expedition died.
Jarle Andhoey told the Norwegian public broadcaster NRK his yacht Nilaya has passed the 60 Degree South mark on its quest.
While Mr Andhoey, 34, and a companion were trying to reach the South Pole on quadbikes a year ago, his expedition's yacht, the Berserk, sank in a storm.
No trace of it or the three crew was ever found and Mr Andhoey says he's determined to discover why the Berserk left its safe mooring.
The Nilaya left New Zealand in a hurry last month, after Norwegian authorities asked New Zealand to stop the new expedition.
As well as Mr Andhoey, it carries three crew and an Auckland man who happened to be working on the boat when it abruptly departed.
NRK journalist Runar Henrickson Joerstad told Morning Report the Nilaya crew are looking for equipment from the sunken vessel which Mr Andhoey hopes will uncover the truth about the sinking.
