A new electronic monitoring anklet has been rolled out by Corrections that monitors an offender's sweat for the presence of drugs and alcohol.
It's part of a crackdown on offenders who breach their bail conditions, which usually include a ban on consuming alcohol.
Corrections Minister Louise Upston says the anklet remotely sends information back to officials.
"It automatically is able to give either police or Corrections information about what that person's doing and if they've breached their conditions associated with their use," she said.
New laws were needed to allow the rollout of the anklets.
