A Labour government would be likely to ditch the three-strikes law for repeat offenders, a controversial policy the party vehemently opposes and says is not working.
It would also dump privately run prisons and put an extra 145 police constables on the streets at a cost of $96 million over four years under its police and corrections policy released yesterday.
The three-strikes regime was passed into law last year, making it mandatory for judges to impose harsher sentences on repeat criminals convicted of one of 40 violent or sexual offences.
An offender receives a normal sentence and a warning for strike one, a sentence without parole for strike two, and the maximum sentence for that offence, without parole, for strike three.
Labour's law and order spokesman, Clayton Cosgrove, said a Labour-led government would review how the policy was going.
"But it's not working, it's not appropriate, it's not our policy ... It would take something seismic to convince me that three strikes should be retained.
The policy has been criticised as removing judges' discretion, leading to sentences disproportionate to the crime.
But Corrections Minister Judith Collins said three strikes was an effective deterrent and should not be repealed. "Why would you do that? You're talking about the high-end violent recidivist offenders, exactly the people you want locked up."
She said deterrence had contributed to the predicted fall in the prison muster, even though the Ministry of Justice report did not credit three strikes as a factor.
"It does work, because of the comments that police and Corrections are getting from prisoners," Ms Collins said.
Labour is also promising 145 extra constables, including changing the 62 one-person police stations in small communities around the country into two-people stations.
Mr Cosgrove said that when the rural stations needed back-up it sometimes took an hour to arrive from the city.
The policy also focuses on low-level crime and low-level criminals, on the basis that "nipping this stuff in the bud" earlier would help to prevent offenders from getting involved in more serious crimes.
Rehabilitation programmes in prison should be more open to the 80 per cent of prisoners serving less than a two-year sentence, Mr Cosgrove said.
"It will not be the length of the sentence that will be the determining factor in what programme you get, but whether the programme will aid in rehabilitation."
But Ms Collins said that already happened.
"He's so far out of date. He hasn't kept up with the number of people accessing drug and alcohol treatment programmes in our prisons, which now focus on short-term prisoners," she said.
"Clayton doesn't know what he's talking about. The fact he hasn't asked me a question about Corrections in the House since June 2010 shows it's not a high priority for Labour."
