Police are asking for any witnesses who may have seen a vehicle "driving at speed" before a fatal crash on Bluff Hill in Napier on Saturday night to come forward.
An overloaded car with nine occupants flipped after hitting a parked vehicle on Shakespeare Rd about 11.50pm. One person was killed and five were badly injured.
As of today, one woman in her 20s was in a critical condition in Christchurch Hospital, a teenage boy was in a serious condition in intensive care in Wellington Hospital, and a teenage girl was in a stable condition in Hawke's Bay Hospital.
Two others who were in hospital on Monday have since been discharged.
