The father of a teenager killed in a police pursuit in West Auckland last year is challenging a report clearing the police of any wrongdoing.
Sina Naraghizadeh died when he lost control of a stolen vehicle during a pursuit in Hobsonville.
The 19-year-old was pulled over when police saw the Subaru stationwagon he was driving go through a red light.
When an officer approached the vehicle on foot, the teenager sped off and was pursued for nearly five minutes before losing control of the car and crashing.
The Independent Police Conduct Authority has concluded that the pursuit was conducted according to law and policy.
The teenager's father Vahid Naraghizadeh says he is sure the police did something wrong.
He says they should have abandoned the pursuit sooner, there was no communication during the chase and there was no helicopter, which would have allowed the officers to keep their distance.
The authority has cleared also cleared police of any wrongdoing in relation to two other pursuits in which the drivers were killed.
Caine Burgess and Robert Seifert died immediately following separate pursuits last year where speed was a contributing factor.
The police officers involved reported travelling at speeds of up to 140 km/h in 100 km/h zones.
Passengers involved in one of the pursuits say the vehicle they were in went as fast as 200 km/h before it crashed.
The authority says the pursuits were justified and it is confident the police prioritised public safety during them.
It says no recommendations have been made as a result of its findings.
