Kiwi soldiers were confronted with a "chaotic scene" when they rushed to rescue survivors of a plane crash in Papua New Guinea, the Defence Force says.
Three people, including both pilots, were killed when a Hevilift Twin Otter aircraft crashed near near Port Moresby on Saturday morning.
A fourth person, one of nine people aboard the plane, died in hospital on Sunday.
The plane crashed 3km from a base where soldiers from the New Zealand and Papua New Guinea defence forces had been training.
Personnel from both forces, including medics and a doctor, worked together at the crash site to remove debris from the aircraft, cut tracks, and treat and later evacuate the survivors, some of whom were in serious condition.
