"He had accidentally left his insulin behind in his motor-car and was concerned about his blood/sugar levels," the spokeswoman said.
He was assessed by the Order of St John Paramedic at the hut and the man was well enough to be airlifted back to the car park where his medication was.
"The man was dropped at his car after confirming he had located his insulin and was well enough to continue."
Later that day at 6pm the same emergency locator beacon was activated in the Ruahine Range near the Dead Dog Hut.
The rescue helicopter again responded to the call by Rescue Co-ordination New Zealand concerned that the man found earlier had fallen to further complications.
Crew found the man safe and well and the beacon had accidentally been reactivated in the back of his car.
An emergency beacon was also activated early on Christmas Day as two men were found stuck on a steep ridgeline.
The beacon alert came from the Ruahine Range near Awatere Hut from two men who were hunting.
"The helicopter landed near the hunters on the ridge saddle and an advanced Order of St John Paramedic attended the one male hunter who appeared to have fractured his lower leg while traversing a steep slope," the spokeswoman said.
Both men were flown from the Range.
The spokeswoman said even though emergency beacons can go off accidentally it is better people have them than not - especially when out of cell phone reception.
"They have been known to save lives and accidents can happen at anytime. I recommend when tramping, hunting or even sunbathing at the beach where there is no coverage to have one near by."
Also on Christmas Day, the rescue helicopter transported a man who fell off a bike from Kotemaori to Hawke's Bay Hospital.
He received arm and shoulder injuries and was seen by Order of St John Paramedics at the scene before being airlifted to hospital.
Around 9pm On Boxing Day the helicopter responded to a man who appeared to have suffered a cardiac arrest near the main street of Waipukurau.
The helicopter landed at a nearby school so staff could respond to the man, who was already recieving CPR, however the man died at the scene.
Senior Sergeant Nick Dobson of Eastern District Police said as the man had a large cut on his head, they were unsure if his death was caused by the cardiac arrest, or a fall.
Police said his death was not being treated as suspicious, and had been referred to the coroner.
Earlier that day at 2:50pm a man was airlifted from Mahia Beach with cardiac complications and was taken to Hawke's Bay Hospital for further investigation and treatment.
