Police have interviewed one of the teenage girls who was seriously injured after a police pursuit in Auckland two weeks ago but are still appealing for witnesses to come forward.
The girl is one of four aged 16 and 17 who fled from the police in a stolen vehicle and crashed into a concrete wall on 3 March.
Three of the girls remain in hospital in a stable condition.
Police say they are hoping to speak to a driver who pulled over to let the cars pass during the chase.
They believe that person may hold key information.
