Two people were rescued near the summit of the Tongariro Alpine Crossing on Tuesday afternoon.
They were on the third day of a hike around the Tongariro Northern Circuit.
Senior police constable Barry Shephard said the pair had successfully climbed to the Red Crater summit from Emerald Lakes but on the descent to South Crater they found themselves in trouble on ice.
“The two called police at around 2.40pm yesterday (Tuesday) requesting assistance as they did not have sufficient equipment for the conditions,” he said.
“Police quickly launched a mission using a helicopter from Taupō and LandSAR (search and rescue) rescuers, and the pair were rescued a short time later.”
