Eastern District Commander Superintendent Sam Hoyle accepted the findings and had already reinforced to staff police policy around fleeing drivers.
"The officer involved in the incident has undergone remedial training and has been recertified as a 'gold' licensed driver under the Professional Police Driving Programme," Mr Hoyle said. "He is well aware now of his responsibilities should such an event occur again.
All staff would be "extra vigilant" in any future pursuits they undertake, he said.
Mr Hoyle said communications centres were also reviewing their practices for handing control of fleeing driver incidents from one supervisor to another.
"The dispatcher involved in this incident has undergone refresher training in the requirements of the fleeing driver policy, and the pursuit controller has been reminded of the policy's abandonment procedures."
The pursuit occurred after Mr Kingi failed to stop after a police officer spotted him speeding in a 50km/h zone. When the officer notified police central communications, the dispatcher mistakenly noted that the pursuit was taking place in a 100km/h zone, rather than a 50km/h zone, and later also misheard the name of the street.
Shortly afterwards the officer lost sight of the fleeing car after mistakenly turning to follow the wrong vehicle.
He didn't follow policy for abandoning a pursuit which required officers to stop, turn off lights and sirens, and inform police communications, the report said.
The officer continued looking for the fleeing vehicle, and found the crash scene a short distance away.
An investigation found the car had slid off the road after taking a corner at between 130km/h and 136km/h.
Mr Kingi, who had four drink-driving convictions, was found to have more than double the blood alcohol limit.
The authority concluded the officer was correct in starting the pursuit, which covered 2.5km in 1.5 minutes. However the officer's speed of 127km/h in a 50km/h zone was not justified, and the pursuit should have been abandoned earlier.
