University-Led Research Illuminates Shifting Drug Markets in New Zealand
New Zealand universities continue to play a pivotal role in generating evidence that informs public health strategies and student wellbeing initiatives. A recent study from Massey University researchers examines how social media and messaging apps have transformed the way some New Zealanders obtain illicit substances, offering fresh data drawn from the ongoing New Zealand Drug Trends Survey.
The work, conducted by the SHORE & Whariki Research Centre within Massey University’s College of Health, draws on responses from more than 10,000 people who use drugs. It highlights demographic patterns and platform preferences that university administrators and student support teams may find relevant when designing harm-reduction programmes on campus.
Context of Drug Research Within New Zealand Higher Education
Massey University has long contributed to national understanding of substance use through its annual New Zealand Drug Trends Survey. This large-scale online effort, promoted via targeted social media campaigns, captures the experiences of thousands of respondents aged 16 and older each year. The latest analysis focuses specifically on the digital channels used for transactions, moving beyond earlier broad surveys to differentiate between platforms such as Facebook Messenger, Snapchat, Instagram and higher-security messaging services.
Such research aligns with broader university commitments to evidence-based policy advice. Tertiary institutions across New Zealand, including those funded through the Tertiary Education Commission, increasingly support projects that address community health challenges while training the next generation of public health researchers and practitioners.
Key Findings on Platform Preferences and Demographics
The study found that approximately 16 percent of respondents who had purchased drugs in the past six months had done so via social media or messaging apps. Facebook Messenger emerged as the most commonly cited platform at 54.2 percent, followed closely by Snapchat at 47.5 percent and Instagram at 24.7 percent. Younger participants aged 16 to 21 showed a marked preference for Snapchat, while older respondents were more likely to report using Facebook Messenger or encrypted services such as Telegram, Signal or Wickr.
Platform choice also correlated with the range of substances obtained and the types of sellers encountered. Facebook Messenger users reported transactions with the widest variety of seller categories, including gang members, independent dealers and personal contacts. High-security app users tended to report access to a broader spectrum of drug types within the preceding six months.
Implications for Student Populations and Campus Services
University student cohorts, many of whom fall within the 16–21 age bracket identified as heavy Snapchat users in the study, represent a demographic particularly engaged with these digital marketplaces. Student health services at institutions such as Massey University, the University of Auckland and Victoria University of Wellington routinely monitor substance-use trends to tailor counselling, education and referral pathways.
The convenience and perceived anonymity of app-based purchasing noted in the research underscore the need for universities to integrate digital-literacy components into existing harm-reduction workshops. Conversations about encrypted messaging, privacy settings and the risks of expanding personal networks online can complement traditional campus campaigns focused on alcohol and other substances.

Connections to National Policy and Regulatory Bodies
Findings from university research teams feed directly into discussions at the Ministry of Health and Health New Zealand – Te Whatu Ora. The data on rising social-media purchasing of substances such as cannabis and MDMA, which increased from 13 percent in 2020 to 24 percent in 2024 for MDMA, provide timely indicators for national drug strategies and enforcement priorities.
Academic contributions like this one also support the Tertiary Education Strategy’s emphasis on research that delivers societal benefit. Projects housed within Colleges of Health across the country help bridge the gap between campus-based inquiry and real-world application in community settings.
Methodological Strengths of the Massey University Approach
The New Zealand Drug Trends Survey employs an anonymous online format promoted through targeted advertising, yielding large sample sizes that capture diverse user experiences. Logistic regression models allowed researchers to isolate demographic and drug-use predictors while controlling for multiple variables. This rigour enhances the credibility of results when presented to university governance bodies and government agencies alike.
Previous iterations of the survey have already documented the digitalisation of drug markets since 2020, establishing a consistent longitudinal picture that strengthens the current platform-specific analysis.
Broader Role of New Zealand Universities in Public Health Research
Massey University’s work sits alongside contributions from other institutions, including the University of Otago’s population-health studies and Auckland University of Technology’s focus on youth wellbeing. Collectively, these efforts demonstrate how higher-education providers generate independent, high-quality evidence that informs both policy and practice.
University research centres also train postgraduate students who go on to roles in Health New Zealand, the New Zealand Police and non-governmental organisations addressing substance-related harm. The pipeline from undergraduate study through to applied research roles remains a key strength of the New Zealand tertiary sector.
Future Directions for University Research and Collaboration
Researchers at Massey University have signalled plans to continue monitoring platform shifts as new apps emerge and existing ones update their features. Future waves of the New Zealand Drug Trends Survey may incorporate questions on emerging technologies such as AI-assisted matching or decentralised platforms, maintaining the sector’s responsiveness to technological change.
Cross-institutional collaborations, potentially supported by the Tertiary Education Commission or Health Research Council funding streams, could extend the geographic reach of such surveys and deepen understanding of regional variations in digital drug markets.

Supporting Student Wellbeing Through Evidence
University administrators can draw on these findings when reviewing student support frameworks. Integrating insights about preferred platforms into peer-education programmes or online safety modules may increase relevance for current cohorts. Partnerships between student associations and research teams further embed evidence into campus culture.
The study reinforces that social media drug purchasing is not confined to any single demographic but shows clear age-related and substance-related patterns that warrant targeted rather than blanket approaches.
Conclusion: Universities as Engines of Insight
The Massey University analysis of drug purchasing via social media and messaging apps exemplifies the valuable contribution New Zealand higher-education institutions make to national knowledge. By combining large-scale survey data with sophisticated analytical methods, researchers deliver findings that resonate across policy, campus services and public understanding.
As digital environments evolve, continued investment in university-led public-health research will remain essential for maintaining responsive, evidence-informed approaches to student and community wellbeing.
