New Zealand has among the highest rates of youth justice involvement in the OECD. Māori rangatahi are massively overrepresented — making up more than 60% of those apprehended by police despite being approximately 25% of the youth population. Community-funded programmes that divert young people from the formal justice system, support those involved in it, and address the underlying factors driving offending represent some of the most important and undervalued grants available. This is also some of the most challenging grantmaking: the politics are fraught, outcomes are long-term, and the population served is among the most marginalised.
Youth Justice in New Zealand operates under the Oranga Tamariki Act 1989 (Children, Young Persons, and Their Families Act). Young people between 10 and 16 who offend are dealt with primarily through the Youth Court and family group conferences (FGCs), rather than adult criminal proceedings. Oranga Tamariki (Ministry for Children) is the lead government agency.
Family Group Conferences are a restorative process — involving the young person, their family and whānau, victims, and professionals — that produce a youth justice plan. FGCs are a core part of the New Zealand approach and reflect a recognition that whānau are central to rangatahi wellbeing and rehabilitation.
Police diversion allows young people apprehended for first or minor offending to be dealt with informally — through warnings, community work, or referral to community services — without formal charges. Community programmes that provide options for police diversion are critical.
Youth Court deals with more serious or persistent offending. Outcomes include supervision, community work, supervision with activities (which may include community programmes), and in serious cases, custody.
Māori overrepresentation is the defining challenge of New Zealand youth justice. The causes are structural: colonisation, poverty, family disruption, housing instability, and systemic bias all contribute. Addressing overrepresentation requires addressing these root causes, not just providing individual-level interventions.
Diversion and prevention programmes:
- Police diversion alternatives (community work programmes, restorative conferencing)
- Youth crime prevention in high-risk communities
- Mentoring programmes connecting at-risk youth with positive adult role models
- Sport, arts, and outdoor programmes as alternatives to street-based activity
Whānau support:
- Family group conference support for whānau who are engaging with the youth justice system
- Whānau advocate programmes to support families navigating the system
- Parenting and family strengthening programmes targeting youth justice-involved families
Kaupapa Māori responses:
- Culturally grounded programmes using te ao Māori frameworks
- Connection to whakapapa, marae, and cultural identity as a rehabilitation pathway
- Rangatahi Courts (a Māori-responsive Youth Court process) support services
- Iwi-led youth development and mentoring
Education and employment:
- Alternative education for young people disengaged from mainstream schooling
- Vocational training and trades opportunities
- Employment support for young people leaving custody
Reintegration:
- Support for young people transitioning out of custody
- Accommodation support (youth in custody are often homeless on release)
- Continuity of therapeutic and educational programmes post-release
Advocacy and systems change:
- Research on youth justice disparities
- Advocacy for policy reform
- Training for professionals working in the youth justice system
The kaupapa Māori imperative. Programmes that do not meaningfully engage with te ao Māori will not effectively reach Māori rangatahi, who are the majority of young people in the youth justice system. Effective youth justice grantmaking in New Zealand requires either funding kaupapa Māori programmes or requiring mainstream programmes to demonstrate genuine cultural competency.
Whānau-centred approaches. Individual interventions that don't engage with family and whānau are less effective. Young people exist within family systems; interventions that treat them in isolation ignore the context that shapes their behaviour. Whānau-centred approaches are not just culturally appropriate — they're more effective.
Addressing the upstream causes. Poverty, housing instability, school exclusion, trauma, and family violence are the drivers of youth offending. Programmes that address these root causes — not just the offending behaviour — produce more durable outcomes.
Relationship and trust. Young people who have had negative experiences with authority figures (police, schools, CYFS/Oranga Tamariki) don't engage with services that look like more of the same. Youth justice programmes that are community-based, delivered by people with credibility in communities (including people with their own lived experience of the justice system), and that build genuine relationships are more effective.
Patience and persistence. Youth rehabilitation is not a linear process. Young people disengage, reoffend, and then re-engage. Programmes that write off young people after a single failure miss the reality of desistance — the long, non-linear process by which people move away from offending. Funders who require clean success metrics will not fund effective youth justice work.
Lived experience. Workers who have their own experience of the youth justice system — who have been through it and come out the other side — are often uniquely effective with young people who don't trust mainstream services. Programmes that employ people with lived experience, with appropriate support and supervision, should be preferred.
Cultural foundations. For programmes working with Māori rangatahi, is the cultural grounding genuine or cosmetic? Genuine kaupapa Māori programmes have Māori leadership, te reo Māori incorporated in practice, whakapapa and tikanga integrated in programme design. Programmes that add a mihi whakatau to an otherwise Western intervention are not genuinely kaupapa Māori.
Evidence-informed practice. What does the evidence say about the approaches being used? Mentoring, restorative justice, and trauma-informed practice all have evidence bases. Programmes that use untested approaches without a clear theory of why they would work are higher risk.
Systemic relationships. Effective youth justice programmes need relationships with police, Youth Court, Oranga Tamariki, and schools. Applications that show evidence of these working relationships — not just claims — are more credible.
Realistic expectations. Youth justice outcomes are long-term and non-linear. Applications that claim to "stop reoffending" for every young person they work with are not credible. Realistic expectations about what can be achieved in a grant period, with an honest theory of longer-term change, are more credible.
Safety frameworks. Youth justice programmes work with young people in trauma and sometimes with people who are volatile or unsafe. Adequate risk assessment, safety protocols, and staff support systems are essential.
Youth justice reporting must balance accountability with realistic outcome expectations:
Activity measures:
- Number of young people engaged
- Number of sessions or contacts
- Demographics (age, gender, ethnicity, justice status)
Process measures:
- Engagement and retention rates (young people who stayed in the programme)
- Completion of programme elements
- Referrals made and received
Intermediate outcomes:
- School attendance and engagement
- Employment or vocational training
- Housing stability
- Family relationship quality (where measurable)
- Young people's self-reported wellbeing
Justice outcomes (with caveats):
- Where available, reconviction data provides the most meaningful outcome measure, but requires data sharing with Police or Courts that community programmes rarely have access to
- Reduced court appearances, police contacts, or custodial remands during the grant period
