Police have released the name of the girl who died in a crash on the Hawke's Bay Expressway last week.

Sapphire Te Aroha Skipper-Hira, 2, of Flaxmere died when the car she was in left the road and crashed on the highway.

Police are continuing to investigate the cause of the crash which occurred just before 5pm on Wednesday last week on the Hawke's Bay expressway half way between Omahu Road and Flaxmere Ave.

Police said last week that they believed the car, a Nissan Primera, crossed the centre line, rolled, and landed in a ditch on the side of the road. District Command Centre Senior Sergeant Dan Foley said the child, sitting in a car seat in the rear of the car, was thrown as the car rolled over.


"Despite efforts from police and ambulance services to revive her, the girl died at the scene," Mr Foley said at the time.

Senior Constable Corey Ubels said last week there had been a secured child restraint in the car, and police did not know if the toddler had been unrestrained initially, or if she had "unclipped" the restraint.
