It was a "beautiful clear day" on the mountain, he said.
"Conditions made it not only good for climbing but good for rescuing as well."
At the same time a search and rescue was launched for a woman in the same climbing party who became stuck on the top of the Pinnacles and was unable to continue, police said.
Taupo's Greenlea Rescue Helicopter was used to send a Ruapehu Alpine Rescue Organisation team to the area to bring the 23-year-old down.
She was retrieved unharmed and without further incident.
Mr Bremner said it appeared the woman had been too frightened to move after her climbing partner had fallen.
"She wouldn't have had the equipment or the support to get down either."
The group were well equipped and experienced and weather conditions were fine at the time, police said.
