A Havelock man suffered chest and leg injuries after being run over by his own ute on Monday morning.
The 41-year-old was on Takorika hill, 3km southwest of Havelock, spraying weeds from the back of the vehicle when it began to roll, Summit Rescue Helicopter spokesman Jarrod Colbourne says.
The man fell under the ute as he tried to climb in the cab, he says.
He was flown to Blenheim's Wairau Hospital for treatment.
