Low-risk prisoners will have their jail time cut if they complete training and treatment programmes behind bars, under new National Party policy.
Under the "positive pathways" scheme, prisoners whose sentences are two years or less and who complete their training and treatment plan will be eligible for release 10 per cent earlier than under current settings.
The radical policy was announced today by Bill English and Corrections spokeswoman Louise Upston.
Prisoners serving more than two years will get a training and treatment plan from Corrections. Successful completion will trigger an earlier parole hearing. However, National said early release is not guaranteed and minimum non-parole periods will remain unchanged.
How to address a record prison muster has become part of the political debate around law and order.
