Prime Minister John Key says he will consider the Act Party's proposal to make burglary a three-strikes offence.
The policy, announced over the weekend by new Act leader Jamie Whyte, would create a separate regime to the existing three-strikes law, which applies to serious violent crimes.
Under that regime, also an Act policy, judges are required to sentence offenders who commit a third violent crime to the maximum sentence without parole.
Mr Key told TVNZ's Breakfast today he would look at the three-strikes burglary proposal.
"We'd have to have a look at all the implications of that - ultimately how much would that cost, what would that mean, what sort of burglaries should be included, over what time period. I haven't had a really good look at those details.
