Satty Thammavong, 27, fell more than 6 metres off a residential Birkenhead roof he was repairing on Monday morning.
Doctors said the plunge should have killed him but he escaped with a cheekbone fracture and shattered ankle - a save he puts down to learning how to fall safely during his time doing parkour, an urban freerunning activity where participants leap over walls and roofs.
"The guy who called the ambulance thought I was dead because there was so much blood around me. I was just dead, couldn't speak, I was in too much pain.
"But I was thinking I can still get up for work. So I tried to move everything but I couldn't feel my legs. That's when I thought 'Oh, damn'.
"I was upbeat though, it's just who I am. If I can still breathe I must be able to do something."
Mr Thammavong, who is a self-confessed adrenalin junkie as well as a keen dancer and gym fanatic, said he checked the roof thoroughly for ice because it was a frosty morning morning but there was none.
As he stood up on the iron roof, he slipped and bounced off the edge but managed to twist his body as he fell to minimise the damage.
It is understood OSH and WorkSafe are investigating the incident.
"I was about to fall on my right shoulder and head but I twisted towards my feet...I literally just cracked my heels and then landed straight on my face.
"The doctors just said I was really, really lucky. Everyone in my family's told me to change careers but, nah. I'll still go back to it.
"I'm just so glad it was me, it wasn't any of the other boys. One of them has five daughters, they've all got kids."
It's not the first time he's had a roofing injury - about six years ago, Mr Thammavong sliced off three fingers and had to have them sewn back on.
The profession is heavily regulated but even the safest construction site comes with its risks, he said.
Another roofer fell off a roof at a previous site Mr Thammavong has worked on and died instantly, he said.
Mr Thammavong's family were in Hamilton when they received calls from the doctors, nurses and police about their son's accident, and immediately drove up to the North Shore Hospital.
They did not know the extent of his injuries and feared the worst, his mother Manichanh Thammavong said.
"I was really shocked. I just didn't speak, I didn't say anything."
His sister Emily Thammavong said it could have been a very different outcome.
The family was enjoying having the Auckland roofer back under their own roof so they could look after him, she said.
"I was really devastated when I heard. We went straight to Auckland but we didn't know what we were in for. Luckily he moved himself as he fell."
Mr Thammavong said he would be house-bound for two months to recover and might need facial surgery but the doctors were expecting a full recovery.
The accident has not changed him but just cemented the important things in life, he said.
"I want to travel more. But I already knew what I wanted. What do you do, you've got to live life.
"I used to be scared of heights, even when I started roofing. But for me, if I can beat my own fear then I'll do it."
