University Research Sheds Light on Post-Ban Retail Shifts
New Zealand's public health landscape continues to evolve rapidly in response to youth vaping concerns, and academic institutions are at the forefront of evaluating these changes. A recent compliance audit conducted by researchers at the University of Otago provides a detailed snapshot of how specialist vape retailers have adapted—or failed to adapt—following significant regulatory updates in 2025.
The study, led by public health experts from the university's Wellington campus, examined 74 specialist vape stores across the country shortly after new rules took effect. These rules included a full ban on disposable vapes, restrictions on product visibility, and tighter controls on advertising and promotions. The findings reveal a mixed picture of compliance, with more than half of stores showing at least some level of non-compliance.
Public health research of this nature plays a vital role in informing policy and protecting young people. New Zealand universities, including Otago, have long contributed to global tobacco control efforts through rigorous, independent studies that track real-world implementation and outcomes.
Background to the Regulatory Changes
In June 2025, New Zealand introduced sweeping reforms aimed at curbing youth access to vaping products while supporting smokers who wish to switch to less harmful alternatives. The key measures included ending sales of disposable vapes, limiting how products could be displayed in stores, and restricting certain forms of marketing and discounting.
These changes built on earlier regulations from late 2023 that had already lowered nicotine limits in single-use devices and introduced safety requirements. Policymakers hoped the 2025 updates would further reduce appeal to young people while addressing environmental concerns associated with single-use plastics.
Academic researchers at Otago saw an immediate opportunity to assess the practical impact. Their work aligns with the university's strong tradition of community-engaged public health scholarship that directly influences national decision-making.
Methodology of the Otago Compliance Audit
The research team employed a systematic audit approach, visiting specialist vape retailers in major centres and regional areas. Researchers assessed compliance with visibility rules, age verification practices, advertising restrictions, and product availability. They also purchased sample products to check pricing and regulatory adherence.
Particular attention was paid to whether reusable starter kits remained available at very low prices, as this could potentially undermine the intent of the disposable ban by maintaining easy and affordable access points for new users.
Ethics approval was obtained through standard university processes, ensuring the study met the highest standards of integrity and participant consideration. Such methodical, evidence-based approaches are hallmarks of higher education research training in New Zealand.
Key Findings on Store Compliance
Results showed that 52 percent of the audited stores were non-compliant with at least one regulatory requirement. Four stores—representing five percent—were still found selling disposable vapes despite the ban.
Product visibility from outside the store was observed in 24 percent of locations, while 40 percent displayed forms of advertising that were no longer permitted. Promotions and discounts that contravened the new rules appeared in five percent of stores.
Age verification practices raised particular concerns, with 48 percent of stores failing to request identification at any point during the audit visit. These gaps highlight ongoing challenges in enforcement and retailer training.
Industry Adaptation and Pricing Trends
While disposable products largely disappeared from shelves, the audit revealed widespread availability of low-cost reusable options. Reusable starter kits were offered for NZ$15 or less in 89 percent of stores, and high-nicotine products continued to be discounted heavily in many locations.
This adaptation suggests retailers are shifting focus to refillable systems rather than exiting the market entirely. The continued presence of very affordable entry-level products raises questions about whether the policy goals around youth protection are being fully realised.
University researchers note that such market responses are common following regulatory tightening and underscore the need for ongoing monitoring and complementary measures such as stronger enforcement.

Implications for Public Health and Policy
The Otago findings provide timely evidence for policymakers and health advocates. They indicate that while the ban on disposables achieved significant reductions in that specific product category, broader compliance with youth-access and visibility rules remains incomplete.
Experts associated with the study emphasise that effective regulation requires clear rules, consistent enforcement, and retailer education. They also point to the importance of addressing environmental impacts alongside health objectives.
New Zealand's higher education sector continues to generate this type of actionable research, contributing to the country's reputation for evidence-informed public health policy.
Role of Universities in Tobacco Control Research
Institutions like the University of Otago have a long history of leading studies on smoking and vaping behaviours. Faculty and postgraduate students often collaborate on projects that combine epidemiological data, policy analysis, and community perspectives.
This latest audit exemplifies how academic work directly informs legislative reviews and enforcement strategies. It also provides valuable training opportunities for emerging researchers interested in regulatory science and public health evaluation.
Similar research programmes at other New Zealand universities support a collaborative national effort to reduce harm from nicotine products.
Challenges and Recommendations from the Study
The authors highlight several areas requiring attention. These include clearer guidance for retailers on acceptable displays and promotions, increased compliance monitoring visits, and consideration of measures to limit ultra-low pricing of starter kits.
They also recommend exploring how the transition to reusable products affects overall consumption patterns and whether additional safeguards are needed to protect younger age groups.
These recommendations reflect the constructive, solutions-focused nature of university-led public health research in New Zealand.
Future Outlook for Research and Regulation
As New Zealand continues refining its approach to vaping, ongoing academic scrutiny will be essential. Follow-up audits, longitudinal studies of youth uptake, and evaluations of environmental outcomes are likely next steps for Otago and partner institutions.
The study serves as a model for how higher education can respond swiftly to policy changes and deliver findings that benefit the wider community. It also demonstrates the value of independent research in holding both industry and regulators accountable.
Looking ahead, New Zealand universities are well positioned to contribute further to global discussions on effective vaping regulation.
Broader Context for New Zealand Higher Education
Public health research at universities supports not only policy development but also the training of the next generation of health professionals, policymakers, and academics. Programmes in public health, policy, and social sciences regularly incorporate real-world case studies like this compliance audit.
Students gain practical experience in research design, data collection, and ethical considerations while contributing to work that has tangible societal impact. This integration of teaching and research strengthens the overall quality of higher education in the country.

Conclusion and Call for Continued Vigilance
The University of Otago compliance audit offers a clear, evidence-based assessment of how the vape retail sector responded to the 2025 restrictions. While progress is evident in the reduced availability of disposable products, significant gaps in compliance remain.
These findings reinforce the importance of sustained enforcement, retailer education, and further research. New Zealand's higher education institutions remain committed to producing the high-quality evidence needed to support healthy communities and informed policy decisions.
As the regulatory landscape continues to develop, academic contributions will be vital in ensuring that reforms achieve their intended goals of protecting young people and supporting those seeking to reduce harm.
