"I wasn't able to stand and my whole body was wet and numb."
At 2pm he contacted his friends who he had started the hike with via WhatsApp and told them to call for help as he was lost and could not walk.
As the rain pelted down on him and the wind thrashed his body, he took his mind off the freezing conditions by continuing to communicate with his friends.
"For five hours I sat in the chilly conditions."
When his battery died at 3.30pm, he plugged it into the power bank he had in his bag, along with some food, water and energy drinks.
He was continuously sharing his location with them while they reassured him help was on the way.
"I was just trying to keep myself calm and praying."
He also munched on some dried fruit to fight off the dizziness.
But as the hours passed he started to get anxious that his rescuers would not be able to find him in the darkness.
"At 6pm it was pitch black and nothing was visible. I was thinking how is that rescue team going to spot me. So I switched on the torch light on my phone and started shouting for help and putting my hand up so they could find me easily.
"When I was trying to put my torch light on my hands and fingers were too numb. I couldn't feel them, but it was that time like when it's a question of survival you push yourself too hard and you do extraordinary things. That's what I did that day."
But after a few minutes of waving his phone around, he would have to put his frozen hand back in his jacket pocket for abut 10 seconds to warm it up again.
The entire right side of his body was numb.
At 7pm, he was finally rescued near the summit of Mt Ngauruhoe in the Tongariro National Park. The temperature had dropped to 7C but due to the 50-60km/h winds, it caused a wind chill factor of about -10C.
Senior Constable Barry Shepherd said the man was frozen and couldn't move. Two rescuers helped him down the mountain to the half-way point at the South Crater where they were met by another rescue team of three.
He was given some warm thermal clothes and food and drink, and the second team helped escort him out to the road's end by 11pm.
Shepherd said while the man had plenty of food and drink for his tramp he had inadequate clothing.
