A coroner has called for a nationwide ban on snow tyres after finding they were the leading cause of a crash which killed a man near Taumaranui.
William Paul, 37, died when the car he was travelling in collided head on with a courier van on State Highway 4 at around 2:30pm on August 10.
The car's driver - Mr Paul's friend and nephew Hayden Lefoe - was seriously injured in the crash.
In a decision released today, coroner Tim Scott said Mr Lefoe had lost control on a corner and skidded into the path of the van.
He blamed the "inevitable slide" on the lack of traction provided by snow tyres fitted to Mr Lefoe's car.
