Surge in Cannabis Possession Charges in New Zealand

Cannabis possession charges in New Zealand have surged by 49% since 2023, reaching an eight-year high. This increase comes despite a law change in 2019 that mandated a health-first approach to drug possession, aiming to reduce criminal penalties. Prior to this change, cannabis possession charges peaked at 3,719 in 2017 but fell to a low of 2,055 in 2021. The recent rise in charges correlates with an uptick in cannabis consumption, as indicated by wastewater testing in the Auckland and Northland regions.

In 2025, the number of cannabis possession charges rose significantly, with 506 individuals convicted solely for cannabis offences, compared to 387 in 2023. Notably, 82% of all cannabis-related convictions also involved other unrelated charges. Police Director of the National Organised Crime Group, Detective Superintendent Greg Williams, noted that the increase in charges aligns closely with a rise in cannabis consumption, suggesting a direct relationship between enforcement actions and usage trends.

Detective Superintendent Greg Williams emphasized that the rise in cannabis charges reflects increased consumption, stating, “If you look at that charging data, it actually perfectly almost reflects what looks like a significant increase in cannabis consumption.” He also pointed out that enforcement actions, including over 100 search warrants executed against organized growers, have led to a temporary drop in cannabis use in Auckland. Conversely, Police Minister Mark Mitchell defended the enforcement of cannabis laws, asserting that police are fulfilling their duty to uphold the law.

Chlöe Swarbrick, co-leader of the Green Party, criticized the government's approach, linking the rise in cannabis charges to the new coalition government that took power in late 2023. She argued, “This is exactly what happens when you have a Government that says it wants to be tough on crime without thinking through the consequences of that.” Swarbrick further highlighted that a significant portion of New Zealanders will have consumed cannabis by the age of 21, questioning whether policing cannabis use should occupy police and judicial resources.

While the increase in cannabis possession charges is clear, the sources do not provide a comprehensive view of the broader implications of this trend on public health or crime rates. Additionally, there is no detailed analysis of the effectiveness of the health-first approach mandated by the 2019 law change in reducing overall drug-related harm.
