The deaths of three young people in a crash raise serious issues about the wearing of seatbelts, a coroner has found.
Coroner Wallace Bain has released his findings into the deaths of three Boston University students in the crash near Taupo on May 12, last year.
The crash claimed the lives of Ross Nicholas Jauberty, Austin Perry Brashears, both 21, and Daniela Rosanna Lekhno, 20.
They were among 16 international students travelling from Auckland to Taupo in two vans. Their intention was to walk the Tongariro Crossing.
The Coroner's finding said one of the vehicles crossed the white line on Rangipo Rd into rough seal at the left of the road, then over-corrected, causing the vehicle to roll four times.
