"There were about six people, all students from an Auckland tramping club. They were fine, in good spirits, and we probably got them out about 4pm [Saturday]," Mr Daly said.
The students were taken to Napier and he expected they would return to Auckland.
They would have to organise when they could retrieve their cars later.
He said parents of the students began calling emergency services when they learnt the trampers weren't coming home when expected. It was a timely reminder for people to check the long-range forecast before "they go into the bush".
"So far we've had three incidents where people haven't checked the weather; two groups became stranded by the snow and another car which became stranded when it tried to cross a ford.
"Also, their cars were inappropriate for the type of terrain they were dealing with."
Mr Daly said the weather was fine when the students began their tramp but people need to look "beyond a few days".
"... and if it is rough, take the safe option and stay away.
The club's captain Harriet Peel said the group had contacted police, family and the club promptly after discovering their vehicles were snowed in.
