Poor weather conditions are making a  search for a plane missing on a flight from the South Pole very difficult.

The New Zealand Rescue Coordination Centre, who are coordinating the search for the Twin Otter aircraft, are yet to make contact with the three Canadian men onboard.

They are also unable to comment on the state of the aircraft or the crew. But hope to be able to drop a kit which includes things like survival gear and a satellite phone at the site.

The aircraft’s emergency locator transmitter was activated at around 10pm last night.

The beacon is transmitting from the Northern end of the Queen Alexandra Range, within New Zealand’s Search and Rescue Region.

It’s hoped conditions will improve overhead.
