\u201cIt is likely that increased supply of cocaine to New Zealand has contributed to the expansion of the domestic cocaine market.\u201d<\/p>\n

T\u0101maki Makaurau District has the highest average cocaine consumption over the last four quarters (271 milligrams per day \u2013 per 1000 people) and was narrowly ahead of Bay of Plenty in Q3 (325mg\/day\/1000 people).<\/p>\n
The New Zealand Drug Foundation says it\u2019s seen a substantial increase in cocaine consumption over the last 2-3 years. <\/p>\n
\u201cGlobally, cocaine production has grown along with the efficiency of illicit supply lines, so we need to prepare for further increases and invest in harm reduction and health services,\u201d says Sarah Helm, NZ Drug Foundation executive director. <\/p>\n
Helm backed up Rawlings\u2019 assertion that, despite the growth, consumption levels are still comparatively low. <\/p>\n
\u201cTo put it in perspective, after adjusting for population, the latest annual data available shows Australia\u2019s estimated cocaine consumption in 2023-24 was over four times higher than New Zealand\u2019s was in the 12 months to September 2025,\u201d said Helm. <\/p>\n
Tasman had the lowest cocaine reading in the latest quarter, with an average of 55mg in Q3 and 27mg over the past year.<\/p>\n

Waikato topped the third quarter testing for methamphetamine, averaging 1879mg per day, per 1000 people. Northland has the highest average over the past four quarters. <\/p>\n
\u201cMethamphetamine use surged in the middle of 2024, doubling nationwide with even more significant increases in some regions. It has remained stubbornly high, and we are starting to see significant health effects,\u201d says Helm.<\/p>\n
\u201cIt\u2019s clear that we can\u2019t rely on supply-side measures \u2013 we need to focus on giving people support and reducing demand. We were pleased with recent announcements from the Government investing in health responses, and we\u2019re hoping to see more in this space.\u201d<\/p>\n
Southern has had the lowest average meth consumption over the past year and in the third quarter.<\/p>\n
It\u2019s the opposite with MDMA. Southern averaged 730mg in Q3, more than double that of the next highest district (Canterbury \u2013 334mg). Southern was the only district to record a notable increase. <\/p>\n
Neither Rawlings nor Helm was surprised by the results. <\/p>\n
\u201cMDMA is a popular recreational drug, commonly used on weekends and at festivals and events. The spike in MDMA in Southern District for Q3 was largely due to high MDMA consumption over the sampling week in July 2025. This generally occurs every July if wastewater sampling coincides with these events,\u201d says Rawlings.<\/p>\n

Helm says the student demographic in the district contributes strongly to the high MDMA readings.<\/p>\n
\u201cThis has been a long-term trend. The largest urban area of the Southern Police district is Dunedin, where a fifth of the city population are students, and almost half of the residents are under 30. We know that MDMA consumption is much more common among younger people (15-24), so this is likely why per capita consumption rates are higher than in other districts. <\/p>\n
\u201cLooking at long-term wastewater data, MDMA consumption has been fairly stable, with some seasonal fluctuations. In fact, over the last 4 years, we have seen a slight drop in consumption of MDMA per capita.\u201d<\/p>\n
Methamphetamine use across sample sites in Q3 2025 equated to an estimated weekly social harm cost of $32.3 million. The estimate is derived from the New Zealand Illicit Drug Harm Index 2023 (DHI 2023). <\/p>\n
By comparison, cocaine\u2019s Q3 social harm cost sat at $2.4M while MDMA was $1.6m. <\/p>\n
The DHI 2023 provides a conservative measure of the harms associated with the use of illicit drugs in New Zealand and considers both personal and community harms. <\/p>\n
Wastewater testing occurs for one week each month; however, the frequency of testing varies between sites. Nationwide testing started in November 2018, with current testing sites covering up to 77% of the total New Zealand population. The three commodities routinely detected in sufficient quantities to accurately report on are methamphetamine, MDMA and cocaine.<\/p>\n
Suspected dumping events are excluded from the data as they do not represent consumption. <\/p>\n
Q4 results won\u2019t be known until early 2026. Rawlings warns anyone planning to add to those statistics over the summer to have illicit substances checked before taking them.<\/p>\n
