Two young males are critically injured in Hawke's Bay Hospital following a crash last night in Waipukurau.
Police believe two cars may have been racing.
The crash occurred on Racecourse Rd on the outskirts of the town around 11.15pm.
Police say the 19-year-old female driver of a dark blue BMW lost control of the car and it slid off the road, hit a culvert and rolled several times down the road. As the car rolled, two of the occupants were thrown from the car. There were four young people in the car, all from Hastings.
Sergeant Clint Adamson of Hawkes Bay Police said it appeared speed and alcohol were contributing factors to the crash.
