A post-mortem examination of Halatau Naitoko, the 17-year-old killed during yesterday's Northwestern Motorway incident, has showed the father-to-be was shot by police.
Auckland Assistant Commissioner Steve Shortland says the investigation into Mr Naitoko's death has so far established that five shots were fired by police at the motorway scene yesterday.
The officers who fired shots have identified themselves to the investigation, but are yet to be formally interviewed.
It was not known if it was a clean shot or if the bullet ricocheted off something before killing Mr Naitoko.
Mr Naitoko, a courier driver whose partner is pregnant with twins, died on Auckland's Northwestern Motorway as an armed man in a stolen car stopped on the busy motorway and tried to commandeer another vehicle using a sawn-off .22 calibre rifle.
Mr Naitoko died in a flurry of shots, some fired by police and some fired by the armed man.
The Independent Police Conduct Authority was investigating the incident and police appointed an officer from outside Auckland, Detective Inspector Peter Devoy, to head its investigation.
