A seven-hour trek to get medical help could have been avoided if two men had taken an emergency beacon with them on a hunting trip in the remote Ureweras, police say.
A 19-year-old Opotiki plumber made the long walk after his 50-year-old father started to suffer chest pains at the isolated Makakoere Hut, about 70km inland from Matawai, on Saturday morning.
The area has no cell phone coverage and the pair, understood to be involved with search and rescue, were not carrying an emergency beacon.
Senior Sergeant Maui Aben of Gisborne police said the father was unable to walk back from the hut, so his son had to make the seven-hour trek to the road.
"The son drove out from the car park, out to Opotiki, when he raised the alarm to emergency services," he told APNZ.
