From Consultation to Supermarket Shelf: The HSR Origin Story
The Health Star Rating system didn't arrive overnight. It was the product of nearly four years of consultation between the Australian and New Zealand governments, food industry bodies, consumer groups, and public health researchers.
Work began in earnest in 2011, when both governments commissioned a review of front-of-pack labelling options. The goal was a system simple enough for a consumer to use in a five-second shelf decision, grounded in nutrition science, and practical enough for manufacturers to calculate from existing NIP data.
After extensive consultation, the HSR system launched on 27 June 2014 as a voluntary scheme. Initial uptake was modest — the first cohort of participating manufacturers included a handful of large food companies who had been involved in the development process. Many manufacturers waited to see how the system landed before committing to artwork changes.
The Early Years: Slow but Steady Adoption (2014–2018)
Between 2014 and 2018, adoption grew steadily. The five-year mandatory review built into the original scheme created a natural "wait and see" incentive — why invest in HSR artwork if the algorithm might change significantly?
During this period, the Health Star Rating Advisory Committee (HSRAC) monitored uptake and issued guidance updates. Companies that launched early found the rating drove genuine consumer engagement, particularly for products in the 3.5–5 star range where a high score was a clear shelf differentiator.
The biggest practical challenge in the early years was the FVNL calculation. Many manufacturers underestimated the complexity of calculating fruit, vegetable, nut and legume percentages correctly — especially for products with multiple ingredient forms (fresh, concentrated, dried) or where supply chain variability affected classification.
The 2019 Interim Review
In 2019, an interim progress report reviewed the scheme's performance. The headline finding was broadly positive: adoption was increasing, consumer recognition was growing (particularly in urban Australia), and the algorithm was performing as intended.
However, the review flagged several concerns:
- Category assignment inconsistency — different manufacturers were sometimes classifying similar products into different categories, leading to incomparable ratings at shelf
- FVNL calculation variability — the methodology for mixed FVNL products was being interpreted differently across the industry
- Low uptake in certain categories — snack foods, confectionery, and quick-service restaurant packaged products had notably low participation rates
These findings fed directly into the scope of the Five Year Review.
The 2023 Five Year Review: The Watershed Moment
The formal Five Year Review, completed in late 2023, was the most comprehensive assessment of the HSR system since its introduction. It examined the scientific basis of the algorithm, industry compliance, consumer understanding, and international comparisons — including Chile's mandatory warning label system, the Nutri-Score used across parts of Europe, and the UK's traffic light system.
What the review confirmed:
- The voluntary approach should continue — no immediate mandate
- The algorithm was scientifically sound and did not require fundamental redesign
- Consumer awareness had grown significantly, with surveys showing more than 70% of Australian consumers now familiar with the HSR graphic
What it recommended changing:
- Strengthen consistency in category assignment guidance
- Improve the FVNL methodology for complex products
- Expand monitoring and reporting of industry uptake
- Develop clearer guidance for products at the margin of automatic ratings
What it flagged for further consideration:
- Whether the system should be made mandatory for products specifically marketed to children
- Whether a mandatory floor would be justified if voluntary uptake plateaued
That final point — the mandatory question — is the most consequential outcome of the 2023 review for manufacturers who have not yet engaged with the system.
Implementation Guide v9: The Current Standard (December 2025)
The recommendations from the Five Year Review were incorporated into Implementation Guide v9, published in December 2025. This is the current authoritative technical reference for HSR calculations in Australia and New Zealand.
If you calculated your product's HSR against an earlier version of the guide — v7 or v8 — it is worth re-running the calculation. Updated tables and revised category guidance can change scores in edge cases, particularly for:
- Products at the boundary between beverage and food classification
- Complex FVNL products with multiple ingredient types
- Category 1D dairy products where scoring tables were updated
Manufacturers who have printed HSR graphics based on pre-v9 calculations should verify their ratings remain accurate under the current guide before the next packaging run.
The Mandatory Question: Where Does Policy Stand?
The most consequential open question for food manufacturers is whether the HSR system will eventually become mandatory — and if so, when and for whom.
The current policy position is that the voluntary approach continues. No government has announced a mandate. However, several factors point toward increasing pressure for compulsory adoption:
1. Children's product targeting
Both the 2023 review and subsequent public submissions raised the question of mandatory HSR for products marketed to children. This is the most commonly discussed pathway to a partial mandate.
2. Retailer private label requirements
Several major retailers have begun including HSR as a preferred or required criterion for private label and exclusive products. This creates a de facto mandate for manufacturers supplying those channels, regardless of government action.
3. International precedent
Mandatory front-of-pack labelling systems in Chile, Mexico, and parts of the EU are being closely watched by Australian public health bodies. If evidence from those systems continues to show population-level behaviour change, the argument for maintaining a purely voluntary approach becomes harder to sustain.
4. The 2028 review
The next formal review of the scheme is due in 2028. If voluntary uptake has not reached the coverage targets set in the 2023 review, a mandate becomes a much more likely outcome at that point.
What This Means for Manufacturers Right Now
If your product portfolio is not already HSR-ready, the question is not whether to engage with the system — it is when.
The practical steps are the same whether you are acting proactively or preparing for an eventual mandate:
- Calculate your ratings now — before a retailer buyer asks, before a mandate takes effect, before a competitor uses a high rating to differentiate at shelf
- Identify reformulation opportunities — sodium reduction, fat profile adjustment, or increased FVNL content can meaningfully improve scores in many categories
- Build HSR into product development — new products should have an HSR estimate at the recipe stage, not at the artwork stage; moving the calculation earlier means reformulation decisions happen when they are cheap
- Verify your NIP data is current — the HSR is only as accurate as the nutritional values it is calculated from; if your NIP was calculated from an older recipe version, recalculate
- Document your category and FVNL decisions — category assignment and FVNL percentage are the two most likely areas of scrutiny if your rating is ever questioned
Calculating Your HSR in Batchbase
Batchbase calculates the Health Star Rating automatically from your recipe's live NIP data, using Implementation Guide v9. When you update a recipe, the HSR recalculates in real time — so you always know if a formulation change has shifted your rating before it becomes a label problem.
