Police are reaching out to locals to identify the driver of a car who may have information about a crash in January which killed a two-year-old.
Sapphire Te Aroha Skipper-Hira died after being flung from a vehicle when it rolled on Hawke's Bay Expressway, halfway between Omahu Rd and Flaxmere Ave on January 13.
Police have released a photo of a car to the public which they believe the driver or occupants of may have key information that will help their investigation.
The statement said there was no evidence to suggest the car played any part in the crash.
But it is thought the car may have been in the same area and the occupants witnessed the fatal crash which happened about 4.50pm.
It is believed the Nissan Primera crossed the centre line, rolled, and landed in a ditch on the side of the road.
A police spokesman said it was believed the girl was not restrained at the time of the crash and they were unsure if she had been unrestrained initially, or if she had unclipped the restraint herself.
A passenger in the car and the driver received moderate injuries and were taken to Hawke's Bay Hospital for treatment. All three occupants were from Flaxmere.
Police ask anyone with information about the vehicle's owner or driver to contact Senior Constable Cory Ubels from the Serious Crash Unit on 06 211 3644.
