Residents saw a car doing burnouts on a grass verge minutes before a vehicle collided with a power pole, killing its driver, a coroner's court has heard.
Peter Wayne Gleeson, 17, was killed instantly in the impact near Kaniere, 30km south of Hokitika, on June 22 last year, an inquest in Greymouth heard yesterday.
He encountered no other vehicles or obstacles before the crash on the long, straight section of road.
Witnesses said a car matching the description of Mr Gleeson's did burnouts and damaged the grass verge before speeding off, minutes before a power cut when the power pole was struck.
Sergeant Philip Ealam told coroner Richard McElrea that Mr Gleeson had been drinking and smoking cannabis the night before the fatality. He drove off about 1am with a friend in the passenger seat.
