This suite of 31 Evidence Briefs, developed by the Ministry of Justice, is a ‘first-stop-shop’ for decision makers and policy developers looking to influence justice outcomes. They provide systematic reviews of justice related interventions summarising New Zealand and international research. They are a basis to make good decisions on where the government invests, what is effective; for whom; when; and why. The Evidence Briefs rank interventions from strong, high quality evidence bases to evidence that is inconclusive, or that supports ending an intervention. Included with the Evidence Briefs is a series of fact sheets containing data on different facets of the justice system.
