A week after the crash 13-year-old Ashatarn Takiwa died of her injuries.
Police today refused to give any further information on the crash, including the status of the other victims or whether anyone would be charged.
Last month Waikato District Commander Superintendent Bruce Bird told Stuff that speed appeared to be a factor in the crash.
He also confirmed the stolen Nissan had been used in a smash-and-grab break-in at a Vape shop in Matamata before the crash.
But Bird said the car did not come to police attention until it left the road.
Witnesses said the crash scene was horrific.
Ashatarn was one of 17 people who died on New Zealand roads over the holiday period.
Her family are reeling over her death and some have posted tributes online.
"I still can't think, speak or comprehend with all this," her mother wrote on Facebook.
"It actually took me a lot of strength to put pics up and write this - don't know what to say."
