Antarctica New Zealand has confirmed the three crewmen on board the Ken Borek Air Twin Otter that crashed on a steep slope on the Queen Alexandra Range in Antarctica, are dead.
Rescuers who have flown to a point near the crash scene are now working on ways to retrieve their bodies.
That part of the mission is expected to be a challenge because of the remoteness of - and difficult access to - the crash site, which is nearly 4,000 metres up Mount Elizabeth.
In a statement, Antarctica New Zealand has extended deepest sympathies to the crewmen's families.
Once the bodies are recovered they'll be flown to Christchurch and then returned to Canada.
