Christchurch couple Kevin Whitburn, 69, and wife Janet, 65, were driving south towing a caravan. They crashed into the truck, which spun and hit the caravan. Both Whitburn and Jayes died of blunt force trauma at the scene.
Wolnak's wife also suffered severe injuries. She was recently discharged from hospital. Two other passengers in the truck also suffered injuries, as did Janet Whitburn.
Wolnak, who is from Wisconsin, told police he remembered nothing after the moment he turned left on to State Highway 60. He has been remanded at large, with his sentencing scheduled for April 24. Judge Bruce Davidson has decided that the restorative justice process should be explored.
A GiveaLittle page set up for Steve Jayes' wife, Monique Hardiman, and their two boys, Lennox and Cassius, has brought in more than $18,000.
