Points

• Public health researchers evaluated 33 government policy cases across Australia and New Zealand published between 2014 and 2025 to examine long-term healthy food retail sustainment.
• Policy mandates in public healthcare settings, such as Victoria’s hospital directives, require food outlets to offer at least 50% healthy foods and maximum 20% unhealthy options.
• Analysis revealed that public policies rely heavily on top-down institutional accountability while failing to specify operational responsibilities and commercial challenges for private food retailers.
• Under-resourced public institutions operating in lower socioeconomic areas face severe capacity constraints that hinder sustained policy compliance and exacerbate nutritional access inequities.
• Long-term public health impacts require harmonized national strategies that balance top-down compliance monitoring with capacity-building support and commercial viability considerations for retailers.

Summary

This study evaluated how national and jurisdictional healthy food retail policies in Australia and New Zealand conceptualize and address long-term sustainment of nutritional interventions in public settings. Given that unhealthy diets drive preventable non-communicable diseases, regulating public-sector food environments—such as hospital cafes, school canteens, and workplace food outlets—serves as a primary public health strategy. Researchers led by Bettina Backman at Deakin University analyzed government policies and accompanying implementation materials published or updated between 2014 and 2025 to determine how long-term policy compliance and practice sustainment are structured across diverse health environments.

Using a multi-theory coding framework combining problematisation theory, the Integrated Sustainability Framework, and Expert Recommendations for Implementing Change strategies, investigators analyzed 33 policy cases across Australia (n = 30) and New Zealand (n = 3). Specific jurisdictional targets, such as Victoria’s healthcare food policy mandating that hospital outlets offer at least 50% healthy options and no more than 20% unhealthy options, were evaluated for structural sustainability mechanisms. thematic analysis identified four primary domains: explicit framing of sustainment as a formal process, implicit problematisation via compliance monitoring, top-down institutional responsibility assignment, and a lack of explicit guidance regarding retailer responsibilities or commercial sustainment challenges.

The findings demonstrate that existing policies rely heavily on top-down accountability frameworks that place primary sustainment responsibility on public institutions, such as healthcare facilities and schools, without accounting for institutional resource disparities. Under-resourced public facilities, particularly those operating in lower socioeconomic areas, face significant capacity constraints in maintaining policy compliance, creating potential health equity gaps. The authors conclude that achieving long-term population health impact requires harmonized national policies that incorporate commercial viability factors, capacity-building mechanisms, and shared responsibility between public health institutions and food retailers.
