"It was dark and foggy at this point and rainy too. It was hard to find the crash scene. When I did, I got straight out and ran down.
"I saw the car was totally damaged, the driver's door was open and saw a body completely folded over. He was half in and half out of the car. I pulled him out of the driver's side."
Emergency services converged on the scene but could not save Simon.
A post-mortem examination confirmed he died as a result of lacerations of the jugular veins, lungs, liver and spleen due to trauma to his neck and torso sustained in the crash.
No drugs or alcohol were found in his system.
Police ascertained the car left the road and went over a steep embankment before it rolled a number of times and landed about 16m away.
Simon would have been going at least 51km/h at the time and there was no sign of any braking.
Police said the seatbelts showed "no sign of use during the crash".
"Calculations ascertained that Mr Norris was travelling too fast to stop," Senior Constable Stephen Lamont told the coroner.
"It is possible Mr Norris became situationally unaware of where he was due to fog and the reduced vision through his windscreen and that, upon realising his vehicle's approach to the right-hand corner, he suddenly counter-steered to his left without applying his brakes.
"Mr Norris was an inexperienced driver, driving downhill on a gravel road while travelling at, or close to, the vehicle's critical curve speed limit for that curve."
Police examined the car and said there were no mechanical faults - however, three tyres were over-inflated.
"Given that over-inflated tyres can cause a vehicle to become unstable in some conditions, this was thought to be a contributing factor," said Lamont.
Coroner Elliot considered whether to make recommendations about the section of road where the crash happened, including installing a wooden barrier and reflective chevrons.
However, he said the absence of those safety measures at the time of the crash could not be clearly linked to the factors that contributed to Simon's death. Therefore, he did not have any power to make the recommendations.
After the crash, Simon's father Ch'e Norris spoke to the Herald about his son.
"It's just really hard. Simon was a great, happy boy. He was a wonderful boy and we are going to miss him," he said.
"He really loved fishing, surfing, he had so many friends. He was looking ahead and was going to go into the Navy or Air Force. He was so loved.
