Complete guide to cannabis laws, penalties, and travel advice
New Zealand sits at a pivotal point in its cannabis policy journey. The country came within a razor-thin margin of legalizing recreational cannabis in 2020, has a functioning medical cannabis program, and has implemented a police discretion policy that effectively decriminalizes small amounts in practice. Yet formal legalization has not occurred, and the legal framework continues to classify all recreational cannabis possession as a criminal offence.
The primary legislation governing cannabis in New Zealand is the Misuse of Drugs Act 1975 (MDA). Cannabis (classified as "cannabis plant," "cannabis preparation," and "cannabis seed") is listed in Schedule 3 of the MDA as a Class C drug — the least serious category, but still a prohibited substance with criminal penalties. Amendments to the MDA over the past decade have significantly changed how the Act is applied in practice.
The most significant practical change was the Misuse of Drugs Amendment Act 2019, which introduced a statutory presumption in favor of health-based responses. Under this amendment, police must now consider whether to caution, refer to health services, or issue infringement notices before deciding to prosecute for personal use and possession offences. This doesn't eliminate the possibility of prosecution, but it fundamentally changed policing culture around cannabis possession for personal use.
New Zealand's medical cannabis framework — the Medicinal Cannabis Scheme — was established in 2019–2020 and created a fully regulated system for patient access to medical cannabis through licensed suppliers and standard health practitioner prescriptions. This system is widely regarded as well-designed and patient-accessible compared to many other countries.
The failed 2020 referendum remains a defining moment. New Zealand came closer to recreational cannabis legalization through a democratic vote than almost any other country to that point. The political aftermath — widespread acceptance that legalization has majority or near-majority support, but no government willingness to retry the question — has created a sustained policy limbo.
The Cannabis Legalisation and Control Bill referendum was held on 17 October 2020 alongside the general election. The result was:
The margin — approximately 128,000 votes — was narrow enough that several factors could plausibly explain the outcome:
The Labour government, which won a majority in the 2020 election, had committed to being bound by the referendum result. Following the No vote, the government confirmed it would not implement legalization. Subsequent governments have not indicated willingness to revisit the question.
Under the Misuse of Drugs Act 1975, the formal penalties for cannabis possession remain on the books, but the 2019 Amendment Act and subsequent police guidelines have substantially changed how these are applied:
| Offence | Formal Maximum Penalty | Practical Outcome (Post-2019) |
|---|---|---|
| Possession of cannabis (Class C) | 3 months imprisonment OR NZD $500 fine | Caution or health referral in most cases; prosecution rare for small amounts |
| Possession for supply | 8 years imprisonment | Prosecuted — supply intent inferred from quantity, packaging, scales, etc. |
| Supply/dealing | 8 years imprisonment | Prosecuted with priority |
| Cultivation (personal) | 7 years imprisonment | Prosecuted; discretion possible for 1–2 plants personal use |
| Cultivation (commercial) | 7–14 years imprisonment | Prosecuted with priority |
| Importing cannabis | 14 years imprisonment | Prosecuted without exception at border |
The New Zealand Police have published guidance indicating that possession of up to 14g of cannabis for personal use should ordinarily result in a caution, warning, or referral to health and addiction services rather than prosecution. This 14g figure corresponds to the possession limit that would have been legal under the defeated referendum bill — an interesting coincidence (or deliberate alignment) in the police guidelines.
Prosecution for personal possession does still occur in New Zealand, particularly where other factors are present (driving offences, other criminal matters, failure to comply with cautions). The risk is not zero, but it has substantially decreased since the 2019 amendment.
New Zealand's Medicinal Cannabis Scheme is regarded as one of the more patient-accessible medical cannabis systems globally. It was established under the Misuse of Drugs (Medicinal Cannabis) Regulations 2019, with the first licensed products available from April 2020.
Key features of the New Zealand Medicinal Cannabis Scheme:
Epidyolex (cannabidiol oral solution) is registered in New Zealand for pediatric epilepsy syndromes (Dravet syndrome and Lennox-Gastaut syndrome). Sativex (nabiximols) is also registered for multiple sclerosis spasticity. Beyond these registered medicines, numerous unregistered products are available under the Medicinal Cannabis Scheme.
Personal home cultivation of cannabis remains illegal in New Zealand despite the police discretion framework. The Misuse of Drugs Act creates a maximum penalty of 7 years imprisonment for cultivation, though personal use cultivation of 1–2 plants is unlikely to be prosecuted under current police guidance.
Licensed commercial cultivation for medical purposes is permitted under the Medicinal Cannabis Scheme. Cultivators must hold a Cultivation Licence from the Ministry of Health, meet security, record-keeping, and quality standards, and supply only to licensed manufacturers or other licensed parties. The domestic cultivation sector includes several licensed sites producing high-quality medical cannabis flower and extracts.
Industrial hemp cultivation (low-THC varieties) is permitted under the Industrial Hemp Regulations 2006, requiring a licence from the Ministry of Health. Hemp cultivation for fiber, seed, and CBD has grown into a small but established New Zealand agricultural sector.
New Zealand has one of the highest rates of cannabis use in the developed world. The 2019/20 New Zealand Health Survey found that approximately 15% of adults had used cannabis in the past year — one of the highest figures in the OECD. Cannabis use is particularly prevalent among younger adults, Maori communities, and in rural areas.
Maori engagement with cannabis policy has been an important dimension of the reform debate. Maori are disproportionately represented in cannabis convictions relative to their share of the population — a disparity that advocates have highlighted as evidence of unequal enforcement. Maori health organizations, including several iwi health providers, have been engaged in medical cannabis access and harm reduction initiatives. Several major iwi have invested in or explored participation in the licensed medical cannabis industry.
New Zealand's cannabis culture reflects its geographic isolation and outdoor lifestyle. Domestic cannabis cultivation — often in home gardens or on rural properties — has been common practice for generations. The country's climate, particularly in the Northland, Bay of Plenty, Hawke's Bay, and Marlborough regions, is suitable for outdoor cannabis cultivation. There is a well-established culture of backyard growing that predates any formal policy discussion.
The reform movement in New Zealand has been sustained and politically engaged. The Drug Foundation of New Zealand, the Helen Clark Foundation, and academic researchers at several universities have contributed to robust public evidence and advocacy around drug reform. The 2020 referendum, while narrowly defeated, mobilized cannabis reform advocates and demonstrated the political viability of the issue.
New Zealand is a relatively low-risk cannabis destination compared to many countries, but travelers should understand the boundaries clearly:
New Zealand's cannabis policy has been in a holding pattern since the 2020 referendum, but several developments are worth tracking:
Cannabis is not legal for recreational use. A referendum on legalization failed narrowly in 2020 (50.7% No). Medical cannabis is fully legal under the Medicinal Cannabis Scheme since 2020. Recreational possession remains technically illegal but police now use health-first discretion, rarely prosecuting small personal amounts.
The Cannabis Legalisation and Control Bill referendum was held on 17 October 2020. The result was 50.7% No and 46.1% Yes. The narrow defeat was attributed to COVID-19 disruption of the Yes campaign, late-breaking undecided voters choosing No, and concerns about youth access. No new referendum has been called.
The Medicinal Cannabis Scheme launched in April 2020. Any registered health practitioner can prescribe medical cannabis — no specialist requirement. There is no fixed qualifying condition list. Both domestic and imported products are available from licensed suppliers. Most products are not subsidized, making them relatively expensive.
The formal maximum penalty is 3 months imprisonment or NZD $500 fine. However, the 2019 Misuse of Drugs Amendment Act requires police to consider health-based responses first. Police guidelines indicate possession of up to 14g should ordinarily result in a caution or health referral. Supply carries up to 8 years; importation up to 14 years.
