Substance use and addiction affect a significant proportion of New Zealand's population, with cascading consequences for health, family stability, employment, and community safety. New Zealand's alcohol and other drug (AOD) services — residential treatment, community outpatient programmes, peer support, harm reduction, and withdrawal management — are funded through a complex mix of government contracts and philanthropic grants.
This guide covers the AOD funding landscape in New Zealand and how grantmakers can support effective addiction services.
Co-occurring mental health and addiction (dual diagnosis) is common — many people accessing mental health services also have substance use disorders, and vice versa.
Residential treatment
Withdrawal management (detox) and residential rehabilitation for people with severe addiction. Residential treatment provides an intensive, supportive environment for early recovery. Programmes range from 28-day crisis rehabilitation to longer-term therapeutic communities. Many residential services in New Zealand are operated by non-profit organisations — Odyssey, Salvation Army, Prison Fellowship, iwi-led programmes.
Community outpatient services
The majority of AOD treatment occurs in community settings — counselling, case management, harm reduction advice, and referral. Community AOD services are typically contracted by Te Whatu Ora (Health New Zealand).
Opioid substitution treatment (OST)
Methadone and buprenorphine maintenance treatment for opioid dependence. OST reduces mortality, crime, and social harm significantly. Access to OST in New Zealand varies — better in cities, often limited in rural areas.
Harm reduction services
Services that reduce the harms of drug use without requiring abstinence — needle exchanges, naloxone distribution (the opioid overdose reversal drug), drug checking services. The NZ Drug Foundation leads advocacy for harm reduction; needle exchanges are operated by various providers.
Peer support and recovery communities
Peer support — people in recovery supporting others — is increasingly recognised as a valuable component of AOD recovery. Alcoholics Anonymous and Narcotics Anonymous provide peer networks; CADS (Community Alcohol and Drug Services) and others support peer-led recovery community organisations.
Family and whānau support
Addiction affects families profoundly. Services for families — education, support groups, counselling — support recovery by improving the family environment and helping families care for themselves.
Kaupapa Māori AOD services
Māori-led AOD services use cultural reconnection, te ao Māori, and whānau-centred approaches that produce better outcomes for Māori than mainstream clinical models. Organisations like Te Arawhiti, Whare Tiaki, and iwi-based services provide this cultural grounding.
Youth AOD services
Young people with substance use problems need age-appropriate, developmentally sensitive services — different from adult AOD treatment. School-based programmes, youth-specific outpatient services, and residential programmes for young people address this age group.
Health New Zealand / Te Whatu Ora: Primary funder of AOD services through district contracts with community providers. Funding for residential treatment, outpatient services, and OST.
Ministry of Justice / Corrections: Funds some in-prison AOD programmes and court-ordered treatment.
Accident Compensation Corporation (ACC): Funds some AOD services where substance use is related to injury.
Lotteries NZ: Some community AOD and harm reduction grants.
Capital for residential services
Residential treatment facilities need physical infrastructure — housing, facilities, vehicles. Capital grants support building and upgrading these facilities where government operational funding doesn't cover capital costs.
Kaupapa Māori service development
Culturally grounded AOD services for Māori are underfunded relative to need. Grants supporting the development, scaling, and evaluation of kaupapa Māori AOD approaches strengthen the most effective services for Māori communities.
Harm reduction infrastructure
Needle exchange, naloxone distribution, drug checking, and supervised consumption services reduce death and disease from drug use. These services are sometimes politically controversial and philanthropy can fund them when government is constrained.
Peer support and recovery communities
Peer recovery support organisations and recovery community centres create long-term recovery environments. These are often not funded by mainstream health contracts. Philanthropic grants enable peer-led recovery infrastructure.
Rural service access
AOD services are concentrated in cities. Rural communities face significant barriers to access — travel distances, limited services, workforce shortages. Grants supporting rural AOD service delivery (telehealth, outreach, mobile services) improve equity of access.
AOD sector advocacy
Organisations advocating for evidence-based drug policy — harm reduction approaches, treatment access, drug reform — need philanthropic support. The NZ Drug Foundation, SHORE and Whariki Research Centre, and others work on systemic policy change.
Research and evaluation
What works in addiction treatment, for whom, under what conditions? New Zealand-specific research informs policy and practice. Grants supporting evaluation of AOD programmes and translation of research into practice improve sector effectiveness.
Evidence-based approaches matter: Not all AOD interventions are equally effective. Abstinence-only programmes without medication-assisted treatment have lower efficacy for opioid dependence than evidence-based OST. Funders should assess whether funded services align with current evidence on addiction treatment.
Non-judgemental, person-centred approaches: Stigma is one of the most significant barriers to help-seeking for people with addiction. Services that operate from a non-judgemental, person-centred framework attract and retain more people in treatment.
Dual diagnosis complexity: Many people in AOD services also have mental health conditions. Integrated treatment — addressing both together — is more effective than sequential or parallel treatment. Assess whether funded services have capacity for dual diagnosis.
Kaupapa Māori approaches: For Māori with substance use disorders, culturally grounded services produce better outcomes. Funders should actively support Māori-led AOD services rather than requiring Māori to fit into mainstream clinical models.
Harm reduction vs abstinence: Harm reduction (reducing the harms of drug use without requiring abstinence) and abstinence-based treatment serve different people at different stages of recovery readiness. Both have legitimate roles; funders should not artificially restrict to one approach.
Tahua's grants management platform supports health and social services funders managing AOD grant portfolios — with the reporting, compliance tracking, and impact measurement tools that help funders invest effectively in addiction recovery and harm reduction.
