However, the trust said the man was found safe and well and the beacon had been accidentally activated in the back of his car as he was leaving the car park at the Ruahine Range.
The rescue helicopter went out again after the rescue co-ordination centre was unable to reach the man to make sure it had not been accidentally activated so assumed it was an emergency.
Hawke's Bay Helicopter Rescue Trust marketing and fundraising manager Laura Hyde said: "We recommend that if you are tramping, working in, or visiting remote locations where there may not be cell phone coverage, that you carry a Personal Locator Beacon [PLB]. They really do save lives should an emergency happen."
