The Cabinet has approved the introduction of alcohol-monitoring bracelets for high-risk offenders and those bailed in the community.
Corrections Minister Anne Tolley said alcohol was a major driver of crime, and the monitoring bracelets were another tool to support police, increase public safety and reduce reoffending.
It is expected that upto 475 offenders and people on bail will be fitted with the bracelets each year.
The ankle bracelets detect the presence of alcohol through the skin.
A signal is sent to a central monitoring system and if alcohol is detected action will be taken, such as arrest or a breach charge being laid in court.
