Police chases across the country are under review after a string of fatal crashes.
The Independent Police Conduct Authority and New Zealand Police started the joint review in July.
About 300 drivers flee police every month.
The review wants to understand pursuit environments, and to identify issues with how police manage them.
The about 75 police pursuits reported to the authority between January 1 and December 31 - those involving death or injury - will be examined, plus a 10 per cent random sample of about 200 other chases between July 1 and December 31.
A joint working group will meet fortnightly.
