All members were suffering from varying degrees of hypothermia, said Sergeant Andy Brooke, Manawatu SAR co-ordinator.
"The men and their dogs were very lucky and this situation once again highlights the need to be prepared for emergencies and have alternate plans when venturing into the outdoors, whether it is into the hills or on the water," he said.
"All members of the group were under-equipped to handle a change in plans when the elements deteriorated and did not carry any form of shelter or weather appropriate clothing to spend a night out in the bush.
"Cell phones should not be relied upon as a means of emergency communication. People should consider taking an emergency locater beacon or a radio hired from the Mountain Radio Service."
