More than a million people go tramping every year in Aotearoa.
Most return home safely but each year, there are also more than 500 who need rescuing.
John Tame is one of them - he found himself lost and injured in the middle of Nelson’s Kahurangi National Park after a bad fall.
John was so hypothermic after two freezing nights out in the open that he started hallucinating.
The rescuers who winched him to safety in a chopper say he was close to death.
Watch John’s extraordinary tale of luck, survival and last-minute rescue in Sunday's report above .
