A lost and extremely cold tramper has been spared from certain death after searchers rescued him from a North Island forest park overnight.
Police say the 25-year-old man became lost on a day trek through the Kaweka Forest Park in Hawke's Bay and got caught out by plummeting temperatures.
Eastern District deployment coordinator Senior Sergeant Mike Stevenson said rescuers believed he would not have survived the night had he not been found within hours of his distress call.
The hiker had been mostly well prepared for the day walk but after walking too far into the park and going through snow he became lost and too cold to make his way back out before nightfall.
The hiker did not have appropriate clothing with him for the changing conditions or to keep himself warm past sunset.
