Search and rescue teams had no time for rest over the holiday weekend as a number of trampers in trouble triggered distress beacons - including a mother and two sons forced to spend a night out in the open.
Rescuers said fortunately the rescued people had safety beacons, which had not just saved time, but likely lives.
Rescue Coordination Centre search and rescue mission coordinator Tracy Brickles said a beacon was a life-saving piece of equipment that everyone should bring.
"A beacon should be a standard piece of equipment if you are going off the beaten track regularly, and hiring a beacon can be done relatively cheaply by those venturing out less frequently."
On Friday evening a mother activated her distress beacon after her two sons, 10 and 12, became exhausted in cold wet conditions in the Tararuas.
