The two other passengers were seriously injured, including Mr Thomas, who was trapped in the wreck wrapped around a tree. He spent six weeks in an induced coma fighting for his life in hospital, and started recovery in Christchurch's Burwood Spine Unit, knowing he would never walk again.
The DVD is the latest stage of a commitment he made as he began his rehabilitation.
He first told his story publicly more than a year ago, and featured at the Youth Alcohol Expo in Napier in May. He will be there again when the expo is held at Pettigrew.Green Arena on April 30-May 4, 2012.
He said he had made a decision he wanted to help other young people avoid the types of tragedy he had been involved in, with messages about it and how it could have been prevented.
He maintained contact with Senior Constable Ian Cheyne and Roadsafe HB regional manager Linda Anderson. "We kept talking about how the message can be kept out there," Ms Anderson said.
This week's launch at The Globe Theatre, Ahuriri, displayed the resulting DVD to health, education and other services from as far away as Taranaki and Nelson.
