Arrowtowns Hamish Bagley, 17, died when he was thrown from the car when it left the road on the Lindis Pass.

“Hamish was a member of the Snow Sports NZ High Performance Development team and had been competing on the World Cup circuit,” Snow Sports NZ Chief Executive Marty Toomey said in the statement.
“Hamish was a dedicated athlete with a promising future ahead of him. Any young life taken early is tragic and our condolences go out to the Bagley family and his friends.”
