The Justice International Network NZ was established in 2019 by the Prime Minister’s Chief Science Advisor for justice issues, Professor Ian Lambie, to engage social scientists, lawyers, policy makers, practitioners and Indigenous experts who can provide advice, analysis and reporting on New Zealand’s criminal justice reform and transformation. It is supported by the Ministry of Justice’s Hāpaitia te Oranga Tangata Safe and Effective Justice initiative.

The Justice International Network builds on the Criminal Justice Summit held in August 2018, which saw international experts gather in Wellington New Zealand to discuss justice reform, specifically responses to mass incarceration. The network will provide impartial informed testing and validation of New Zealand’s initiatives and provide a vehicle for sharing lessons from all participants internationally.

The network is led by the Chief Science Advisor to Government (Justice Sector), Dr Ian Lambie. The role of the Chief Science Advisor Justice Sector is to help the justice sector to improve the lives of New Zealanders by advising on the use of best evidence in cross sector work to reduce crime, victimisation and harm. Dr Lambie is a Professor in Clinical Psychology at the University of Auckland. His work focuses on youth offenders, in particular adolescents who sexually offend, children who deliberately light fires and children displaying violent and antisocial behaviour.
