Labour is calling for the Government to do something to prevent quad bike accidents following a spate of serious crashes this summer.
Transport and safety spokesperson Iain Lees-Galloway said concerns around quad bike safety raised by coroners need to be acted upon.
A man was killed at the weekend when he fell from a quad-bike while working on a farm near Ashburton.
Another man has spinal injuries and a dislocated shoulder after a quad bike accident on a farm near Te Haroto on Tuesday.
Last year, four people died in quad bike accidents and 39 were seriously injured, according to the Department of Labour.
Mr Lees-Galloway said he supports the introduction of mandatory helmets, lapbelts and roll bars on quad bikes.
