  1. Evidence Brief: Faith-based Interventions [PDF, 249 KB]

    There is conflicting evidence about whether faith-based interventions can reduce crime. There is some evidence that faith-based interventions can improve the behaviour of prisoners. Faith-based interventions are voluntary and therefore creates a significant selection bias. The largest faith-based intervention in New Zealand operated in Rimutaka Prison from 2003 – 2011 but closed after an evaluation reported it had no impact upon reoffending.

  2. Evidence Brief: Reintegration services [PDF, 418 KB]

    Offenders face a number of challenges when being released from prison, making it difficult for them to successfully reintegrate into society. There is very promising New Zealand evidence that reintegration services reduce reoffending. There is robust local evidence that the reintegration services ‘Out of Gate’ and ‘Release and Work’ provided by the Department of Corrections can reduce crime. The effect of other reintegration services is yet to be evaluated in New Zealand. International evidence ...

  3. Evidence Brief: Prisoner Education and Employment [PDF, 548 KB]

    Correctional education and vocational training reduce reoffending and increases the likelihood of obtaining employment upon release. International evidence suggests that the more effective the educational training programmes are at obtaining and maintaining employment post-release, the greater the reduction in reoffending. International evidence also suggests that adult offenders, 26 years and older tend to benefit more from education and employment programmes and increase their chances of maint...

  4. Evidence Brief: Prevention of Repeat Burglary [PDF, 411 KB]

    Measures to prevent repeat burglary are effective at reducing crime when targeted at the households at the greatest risk of revictimisation. NZ Police provide a range of measures to prevent repeat burglary as nearly one-quarter of households burgled in New Zealand are burgled more than once. There is robust international evidence that risk of repeat burglaries can be reduced with preventative measures put in place such as improving locks on doors and windows, installing security lighting, and re...

  5. Evidence Brief: Mental Health Courts [PDF, 255 KB]

    Ninety-one percent of prisoners have been diagnosed with either a substance abuse, or mental health problem over their lifetime.Mental Health Courts help in some cases to reduce offending. Mental health courts work best for people who have had little or no previous treatment for their mental health difficulties.

  6. Evidence Brief: Therapeutic Interventions for Victims of Intimate Partner Violence [PDF, 313 KB]

    ‘Therapeutic interventions’ are therapies (e.g. counselling, psychotherapy, cognitive-behavioural programmes) designed to help IPV victims to manage its psychological effects (e.g. posttraumatic stress, depression, low self-esteem) and help reduce their vulnerability.

These interventions have not be...

  7. Evidence Brief: Supervision and Intensive Supervision [PDF, 370 KB]

    Supervision is a community-based sentence that targets adult offenders convicted of less serious offences who have relatively straight-forward rehabilitation needs and a lower risk of reoffending. Offenders can be sentenced to supervision for 6 months to 1 year. There is conflicting evidence on the effectiveness of supervision sentences. They are most effective when the intensity of supervision is matched to the offender, treatment is mandatory, and administered by trained probation officers.

  8. Evidence Brief: Situational Crime Prevention [PDF, 419 KB]

    Situational Crime Prevention discourages crime by doing things that make committing a crime more difficult, risky, or less rewarding or excusable. There is robust international evidence that several types of Situational Crime Prevention reduce crime, particularly property crime and public order offences. Evidence suggests that situational crime prevention is most likely to be effective if tailored to the particular context rather than through generic application such as widespread CCTV.

  9. Evidence Brief: Speed Limit Enforcement [PDF, 522 KB]

    Enforcement of speed limit for traffic, such as patrolling and speed cameras, reduces speed levels, road crashes and injuries. There is robust international and local evidence that speed limit enforcement reduces driving speeds, road crashes, number of fatalities and severity of injuries. There is some international evidence that the effects of speed enforcement are greater when a new form of speed enforcement is introduced and for more serious crashes. There is some international evidence that ...
