Police say independent reports into two pursuits, one of which resulted in a death, shows the message is still not getting through to some young drivers.
The Independent Police Conduct Authority has found that police fully complied with the law and police policy during both chases in March this year.

In the first incident, a 16-year-old girl driving a stolen car lost control of the vehicle while fleeing police and crashed into a concrete wall at Kohimarama in Auckland on 3 March.
The authority said the vehicle's speed before the crash was between 90km/h and 103km/h in a 50km/h zone and alcohol was also a factor.
In the second, Callan Moss was killed after the 20-year-old ignored officers' requests to stop and crashed into an oncoming truck in Taupo on 16 March.
The IPCA found both crashes were caused by the actions of the drivers and that speed and alcohol were significant factors. It said while police were not at fault, a policy review is underway.
Assistant Commissioner Allan Boreham said on Thursday that the crashes could have been avoided.
"There is a theme here about young people, young people affected by alcohol, young people travelling too fast - and it's those people that we're speaking to. Just saying to them, if you get signalled by the police - please stop."
Mr Boreham said police are working with the IPCA to ensure its fleeing driver policy is as safe as it can be.
