Rich-lister Gareth Morgan has slammed Norwegian adventurer Jarle Andhoy's illegal Antarctic expedition, saying he hopes his boat sinks.
Mr Andhoy set sail from Auckland last month on the ship Nilaya, aiming to retrace the steps of a previous expedition that made headlines last year when three support crew members died.
He and companion Samuel Massie had attempted to cross the South Pole on quadbikes but the trip turned to disaster when the waiting support yacht Berserk sank in McMurdo Sound.
Mr Andhoy failed to get permission to undertake both expeditions.
Mr Morgan, who is currently on a trip to Antarctica to raise awareness of the importance of the sub-Antarctic islands, has slammed the Norwegian's latest mission in a blog post.
