What is the Investment Approach to Justice?

  • The purpose of the Investment Approach to Justice is to boost crime prevention, and reduce harm from crime, in New Zealand communities.
  • By providing organisations involved in crime prevention with high-quality analysis and research, the Investment Approach will help them to make the biggest difference with the resources available.
  • The analysis and research will focus on understanding which people and places we can expect to be involved in crime in the future and inform justice sector decision makers which approaches would be most effective at preventing these crimes.

How will it be implemented?

There are 4 streams of work underway:

  1. How we measure the burden that crime places on society, and how we can understand if our investments are reducing it. In the welfare system they use a fiscal liability measure. We are exploring that option but are also considering alternatives that may be more appropriate to crime.
  2. Building the statistical models that will help us understand who in the country is most at risk of future offending and victimisation, and to estimate the effect that changing sentencing policy would have on crime.
  3. Understanding what works to reduce crime - not just in the justice sector, but right across government and at all stages of a person’s life. Crime has been extensively studied over many years, but the research findings are not always easy for busy decision makers to find and interpret. An important part of the Investment Approach is gathering this evidence and making it accessible.
  4. Connecting these insights with decision-makers across the system and taking different decisions as a result.

Who is it for?

The Investment Approach is designed to support organisations involved in funding, managing, advising on or delivering services that contribute to crime prevention. Many of these organisations are within government agencies, both within the justice sector and across the broader social sector. The information is intended for decision-makers from Ministers and Judges, down through budget managers and service designers, through to those who operate on the frontline such as Police and Probation Officers, Parole Board members and Youth Justice Social Workers.

What will the Investment Approach to Justice not do?

At this stage the Investment Approach will only focus on activities intended to prevent or reduce crime. This means services like collections, investigations, and legal aid are out of scope.

Will the Investment Approach to Justice lead to automated decision-making?

The Investment Approach does not replace real people making decisions. The information that the Investment Approach provides is designed to help decision makers, not replace them.

Which agency is doing the data analysis and effectiveness research?

The justice sector agencies (Police, Corrections and Justice) are working together, with the help of a specialist provider, to develop the analytical model and do the data analysis.

The justice sector agencies are working closely with the social sector agencies to make sure the models can connect with each other to support comprehensive thinking about investment choices to address social problems, such as crime.

What is the budget for the project?

  • $2m in funding has been set aside from the Justice Sector Fund for the development of the analytical model. This includes project software, design, analysis and research, and quality assurance.
  • $1.5 million has been allocated to the development of the analytical model. This funding is on top of the cost of staff time that the justice sector agencies have allocated to support the modelling and other related research on the effectiveness of crime prevention initiatives.

Will the Investment Approach to Justice use a fiscal liability measure like the Investment Approach to Welfare?

No decision has yet been taken about whether to use a fiscal liability measure in the Justice sector.
