The authority restated a recommendation police develop policies for breathtesting officers involved in critical incidents. However, there was no reason to believe the officer had consumed any alcohol, it said.
The pursuit began after the officer responded to reports the occupants of two cars were interfering with parked vehicles in Grey Lynn.
While driving there he saw the cars run a red light at about 70-80km/h in a 50km/h zone.
The report said he activated his lights and siren, and pursued the cars when they failed to stop and ignored traffic lights along Karangahape Rd before entering the motorway, speeding to about 180km/h.
The officer reached 150km/h, but was told by the Northern Communications Centre to abandon the chase about 1km from where the Nissan crashed at the Market Rd off-ramp.
When he arrived at the scene, the car was on fire, Timoti was dead and his passenger was critically injured.
Timoti's blood samples tested positive for cannabis but not alcohol.
Police policy allows pursuit if a driver fails to stop after being signalled and tries to evade apprehension.
But "safety of the public and officers" takes precedence - pursuit must cease if an offender's identity is known and they could be arrested later, if the distance to the fleeing car becomes too great, or if contact is lost with the communications centre. Regulations governing pursuits have become controversial after a number of fatal crashes. APNZ
