The man chased by police onto Auckland's north-western motorway last Friday had an accomplice, police say.
Stephen Hohepa McDonald faces a raft of charges relating to the high-speed chase and shoot-out on Friday, in which courier driver Halatau Naitoko was accidentally killed by a police bullet.
Police revealed on Wednesday that a 19-year-old woman is also facing charges over the events leading up to the lengthy chase through Auckland's western suburbs.
Detective Inspector Peter Devoy told Checkpoint that McDonald's partner, Margaret Patricia Iris Mann, has been charged with unlawfully getting into a stolen motor vehicle, failing to stop for police and driving while forbidden.
She has already appeared in court twice, and will reappear next month.
Officer who fired fatal shot may meet family
Police Commissioner Howard Broad is supporting a request by the family of Halatau Naitoko to meet the Armed Offenders Squad officer who killed him.
Mr Broad, who visited the family home in Mangere on Tuesday evening to give his condolences, says he told them he'd look into their request.
He says he cannot force people to go into meetings against their will, but he will encourage the officer to take up the opportunity.
Four investigations into the death are under way. Several Armed Offenders Squad members have already been formally interviewed over the shooting.
