The car that hit 14-year-old Rangimaria White might not have any significant damage, police have said.
Rangimaria died after being struck by a vehicle on Goring Street shortly before 3.45am yesterday.
The vehicle failed to stop and the main focus of the investigation is to identify witnesses who may have information about the vehicle and its driver.
Police are also talking to a number of people to establish the movements of Rangimaria on Saturday night and early Sunday morning and the circumstances that led to her being on Goring Street.
Enquiries indicate she had been at a family address a short time before the incident occurred.
