Yesterday's fatal pursuit in Palmerston North will be subject to a range of inquiries.
A15-year-old girl who was a passenger in the car remains in a stable condition in hospital.
Police said the 15-year-old driver of the stolen Subaru who died was in breach of his bail conditions for charges related to serious driving offences.
The 12-year-old girl's brother was also killed in a police pursuit in a blue Subaru car in Australia in October 2013.
A coroner's report says the brother was 18 when he died in October 2013 after getting into the car which being driven by a friend.
A sighting of the stolen car sparked the chase which lasted 80 seconds before the driver lost control on a corner and slid into the path of an oncoming ute, fatally injuring the 18-year-old.
The car was going about 135km/h in an 80km/h zone when it spun out.
The teenager died in hospital the day after the crash.
Inquiries continue into fatal Palmerston North pursuit
Central District Commander Superintendent Sue Schwalger said police started chasing the car after being told a stolen vehicle was possibly being driven by a 15-year-old who was breaching his bail conditions.
At 1.30pm yesterday an officer saw the Subaru on Monrad St, and signalled for it to pull over.
But the Subaru continued on to Pioneer Highway for about 90 seconds and crashed into a ditch hitting a power pole at the intersection of Shirriffs Rd.
The front seat passenger, a 12-year-girl, died at the scene. The 15-year-old driver died later in hospital.
The Serious Crash Unit and the Independent Police Conduct Authority are investigating, and an internal police investigation is under way.
Call for life skills programmes
Palmerston North Youth advocate Billy Meehan said the deaths had devastated the community and he called on authorities to relook at policies and programmes supporting troubled youth.
Yesterday police said the 15-year-old driver of the stolen Subaru was in breach of his bail conditions for charges related to serious driving offences.
"When kids have this idea in their heads that they are 10ft tall and bullet proof, they never see the consequences of what can happen.
"There is no easy fix but the questions raised are, why weren't resources put around this boy to be a little bit more secure and why wasn't he looked after a little more closely?
"The resources needed to be put in the right places so he didn't have the opportunity to have a 12-year-old in a car and take a 12-year-old's life. He shouldn't have had that opportunity," Meehan said.
"The honest truth is we namby-pamby too much. We are too PC. We need to start getting things a little more firmer.
"It is not a simple 'point the finger' and say it is this one's fault or that one's fault, it just doesn't work like that.
"There are all sorts of issues: family issues and cycles and there is no discipline and boundaries in their lives."
Meehan said he put no blame on police.
"They are trying to stop a vehicle that is no doubt driving illegally to start with, so in pursuing them they are stopping them running the risk of taking other lives.
"I don't point the finger at police for pursuing. If we stop pursuits then what is the answer, just to let them run wild and hope one day they stop?
"The ambulance at the bottom of the cliff isn't working any more and we need stronger resources around prevention."
Meehan didn't have answers for how to fix the problem, but said a return to borstals was not a bad idea.
"I know people who went through borstals in the early days and turned their lives around pretty quickly and decided they didn't want to go back there real quick.
"If this boy had been put into some sort of care while he was waiting to be dealt with on the other charges, he wouldn't have had the opportunity to go out and pinch a car."
Meehan said the Government has a major role to play in fixing the problem.
"They are the ones who okay where the money goes, okay what is happening and sign off the programmes.
"More structured programmes that create more discipline in people's lives need to be there.
"These kids mainly need to learn life skills and to understand consequences for what they do so we need more programmes geared around that. Qualifications aren't worth anything if they don't have life skills."
