Tim, who has since celebrated his 14th birthday, has spent many weeks reflecting with his parents, Jill and John Herbert, on the circumstances that put him in hospital on June 6.
They all say they have learned a lot from the experience.
The family is keen to put the incident behind them - but not before thanking the people who saved Tim's life and supported them through their ordeal.
On August 22 and 23, the Herbert family will hold a sausage sizzle in the Wanaka New World Supermarket car park to raise money for St John, Dunedin Hospital's intensive care unit and the Otago Rescue Helicopter Trust.
Mrs Herbert said she had been told if the family had had to pay for the emergency services that rushed Tim first to Dunstan Hospital, Clyde, and then to Dunedin, the combined cost could have been about $8500.
She was also aware St John wanted to raise money for a new four-wheel-drive vehicle for its Wanaka station.
Although the emergency services were free, Mrs Herbert said it was her first experience of them and she wanted to raise awareness of their importance to remote communities such as Wanaka.
She said she came up with the fundraising idea the evening before Tim's 14th birthday, after she burst into tears during a family dinner.
"I thought to myself how lucky we are to have this boy here and then I thought about how I could do something, not just for the community but also to help the community understand how lucky we are to have the services," Mrs Herbert said.
Tim was reluctant to talk to the media about what happened at the Snow Sports New Zealand training camp back in June, where he had his first experience with alcohol.
He was among 33 camp participants staying at the Base Backpackers.
That same weekend, a case of alcohol was unlawfully taken from the Mint Bar, inside the backpacker building.
National media attention followed the police revelation Tim consumed a bottle of Jagermeister spirits (19 standard drinks) in about 30 minutes before falling into a coma.
The police investigation is continuing into four teenagers who allegedly supplied the alcohol to Tim, as well as an alleged assault on him while he was in the coma.
Tim himself is not being investigated. Tim is focusing on representing New Zealand in the boarder-cross snowboard event at the Winter Games NZ later this month, and then the Junior Snowboard Nationals at Cardrona Alpine Ski Resort next month.
"I just want as many people as possible to come to my sausage sizzle, because we want to raise as much money as we can get," Tim said.
