Yesterday Mrs Warren said the report's findings were not surprising: "It comes down to the fact that it was just a terrible, tragic accident".
Mountain biking was a high-risk sport and although her late husband was an experienced road cyclist, he had only been mountain biking since moving to New Zealand in 2014.
"When an accident happens it's one of those things where you could absolutely turn yourself inside out trying to ask 'what ifs' and 'whose fault is it?'. I've never played the blame game…it was just a tragic accident and that's what I have to accept."
The principal said she had no ill-feeling toward the Te Mata Peak Park Trust - or the location itself, which was "a place that was very special to John".
"It sounds cliche to say he died doing what he loved but John…the last thing he posted on Facebook literally 20 minutes before was a photo of him up at the peak saying 'this is why I love riding'."
The Te Mata Peak Park trust yesterday offered their "sincere condolences and sympathy" to Mr Warren's family, and especially his wife.
"We are deeply saddened by this tragic accident," chair Mike Devonshire said.
The coroner made no recommendations about the track's safety, but the trust was recommended to undertake a safety audit of the track.
Based on photographs, "there does not seem to me to be anything particularly dangerous about the track except that it traverses the steep side of Te Mata Peak - which is almost vertical".
"Obviously if a rider loses control and the bike and the rider fall from that track down the steep side of Te Mata Peak there is going to be trouble," the coroner wrote.
"Otherwise I accept that there is an element of risk about many sporting activities and mountain biking is just one of these."
The trust contracted national outdoor safety company Peak Safety and Emergency Management to undertake a "comprehensive" review of the track, which it assessed as low risk when cycling uphill and medium risk when cycling downhill.
Recommendations including further potential risk mitigation strategies, a barrier at the top of the track, and very clear signage, were implemented. The review found a barrier fence was not required on the trail.
The trust also organised a full safety review of all walking and biking trails within the park, and were in the process of undertaking recommendations from this.
Mrs Warren said she was pleased the trust had conducted the audit as it could prevent someone else getting hurt.
She was also working with the trust to create a memorial at the peak for her late husband.
"It's one of those things you never, ever get over, the death of your absolute soulmate and your life partner," she said.
"The loss of John continues to be unbearable for our family. We'll never get over the loss of John, we'll just simply learn how to live with it."
Her late husband had lived his life to the full,she said. He had been principal at the East Coast campus of Westmount School, and before moving to Hawke's Bay was principal of Adelaide's Eynesbury Senior College.
"The thing I know is that John's left a huge legacy for so many people that he touched in his work as an educator, and a mentor, and a leader. I think that's how John lives on, in the hearts and minds of all of the students that he's taught, and all the people he's worked with."
She was very grateful to those who did "everything they possibly could" to help Mr Warren after the accident.
"At the time you don't get the opportunity to say thank you to people but I'm really glad that John, from the moment he had the accident, that there were people there supporting, and helping him."
The report states witnesses went to Mr Warren's aid after hearing a scream and seeing him fall about 20m from the track.
Martin Sharpe said he was walking down the road when he heard a loud scream coming from the direction of the cycle tracks "as if someone was in trouble".
"He said he then saw that a mountain biker was about to fall. The front wheel of the bike appeared to be over the edge. Then the whole bike went over the edge of the track and onto the track below which is a walking track.
"He said the person riding the bike also hit the bottom track, and then fell a further distance about 20m. It was as if the cyclist was sliding down the side of the cliff as opposed to falling through the air."
When he went to help, Mr Sharpe had found Mr Warren alive but unconscious.
Another witness, Colin Hill, said he was looking straight down onto the bike trails when he saw a man fall off the top track.
"He saw the man hit the track below and then keep falling right down to the bottom. He said he was pretty sure that when the man hit the lower track his bike helmet either came off or it wasn't on."
In his findings, Mr Scott wrote that Mr Warren's helmet had been found at the bottom of the track. The coroner said he did not know how it became dislodged, but was satisfied Mr Warren was wearing a helmet before the crash.
The Warrens met in 1997 while they were both teaching at an international school in Brunei. Mrs Warren is moving back to Australia next year, where she will be principal of Woodcroft College in Adelaide.
