Protein Claims on NZ Food Labels: Evidence Before Printing

A protein claim review is more than checking whether a nutrition panel contains a protein figure. For New Zealand food brands, manufacturers and importers, the decision concerns the exact claim, the applicable food and serving basis, and evidence that matches the product being sold.

This guide focuses on protein nutrition-content claims for ordinary packaged foods. It does not provide a separate clearance for infant formula, special-purpose foods, supplements or every export market. Establish the product category first when those boundaries are relevant.

Start with the exact wording and consumer presentation

List the protein references proposed for the front, back and other pack panels, product name and advertisements within the agreed review scope. Include numerical statements, symbols and nearby wording. A short phrase can carry a different meaning when placed beside an image or a statement about what the food does.

Separate a voluntary claim such as “contains protein” from the protein declaration required in a nutrition information panel. Standard 1.2.7 on nutrition and health claims expressly distinguishes mandatory panel information from a nutrition-content claim. A food does not need to qualify for a voluntary protein claim simply because its mandatory panel reports protein.

Write down the proposed statement before asking whether it is permitted. “Source of protein”, “good source of protein”, “high protein” and a comparison with another product should not be treated as identical briefs. This article addresses the first three; comparative claims need their own assessment.

Check the protein conditions in the current Code

Schedule 4’s conditions for nutrition-content claims provide the protein amounts. Standard 1.2.7 explains how general conditions, specific descriptors and synonyms operate together. The following cards summarise that distinction for a review; they are not a complete legal assessment of a particular label.

The Code does not prescribe one compulsory set of claim words. That flexibility is not permission to choose wording first and ignore the applicable conditions. If the intended meaning of a descriptor is unclear, resolve it in the review rather than describing the claim as cleared.

These are New Zealand and Australia Code conditions. A claim copied from an overseas product may use a different regulatory basis. Check the rules for the intended sales market instead of importing a foreign percentage or threshold into the New Zealand assessment.

Check the serving and the form of the food together

Protein claim amounts here are per serving. A figure per 100 g is useful composition information, but it is not automatically the amount in the serving shown on the pack. Check units, serving quantity, pack information and the calculation linking them before comparing an amount with the claim condition.

For a simple illustration, a food containing 20 g of protein per 100 g provides 8 g in a 40 g serving, using the same product basis. That calculation alone would not meet the 10 g-per-serving “good source” condition. This is arithmetic for a hypothetical food, not a product assessment or a recommended serving size.

The form of the food also matters. Section 1.2.7—7 distinguishes food consumed as sold, food required to be prepared according to directions, food reconstituted with water and food requiring draining. Use the applicable form rather than whichever gives the most favourable number. Section 1.2.7—11 requires a statement of the form alongside the claim unless it relates to the food as sold.

For a powder or meal component, provide the directions and explain whether preparation is required or optional. Do not casually add the protein from optional milk or another ingredient to support a claim about the product as sold. Ask the reviewer to resolve the correct basis and required presentation.

Build evidence for this finished food, not a similar ingredient

Start with a controlled formulation, matching ingredient information and the production yield used in the nutrition assessment. A supplier’s description of a protein ingredient does not establish the amount in the finished food after dilution, processing and portioning.

FSANZ’s Nutrition Panel Calculator guidance describes ingredient-data options including laboratory analysis, supplier information and other suitable composition sources. It leaves suitability of external data with the food business. A database entry with a familiar name should not be treated as proof that it matches the ingredient actually supplied.

• Identify the product: variant, formulation version, ingredient codes and finished-product specification.
• Explain the nutrient basis: calculation file, relevant data sources and/or suitable laboratory reports, with dates and product identity.
• Show the calculation context: ingredient quantities, units, finished yield, serving and the applicable prepared or as-sold basis.
• Check representativeness: explain how the evidence relates to normal production and any known ingredient or process variability.
• Link the proposed presentation: exact claim wording, matching nutrition panel, directions and complete artwork version.
• List unresolved questions: identify missing or uncertain inputs and who will obtain them before the affected claim is released.

This is a recommended review file, not a prescribed sampling plan or a demand for new laboratory tests for every claim. Where calculation inputs are unsuitable, results conflict or the product is close to a condition, ask what additional evidence is appropriate. A single favourable result should not conceal contradictory information.

Keep the underlying values and method available for review. Formatting a panel is a separate task from demonstrating that a claim condition is met. Do not use displayed rounding as the explanation for turning an unsupported amount into a qualifying claim.

If the evidence uses saved NPC recipes, our guide to reviewing saved Nutrition Panel Calculator recipes covers that separate data-review task. Updating or recovering a recipe does not itself decide whether the proposed protein claim is suitable.

Recognise when protein wording becomes a health claim

A statement about the amount or presence of protein is different from a statement suggesting an effect on the body. Wording about a physiological function, growth or performance can raise a health-claim question even when the product contains enough protein for a content claim.

FSANZ’s guidance on nutrition and health claims explains that health claims need substantiated food–health relationships and other conditions. Do not treat the 5 g or 10 g content conditions as permission for any muscle, recovery or performance statement. Have the complete health wording and presentation assessed separately.

Keep this boundary visible in the brief. A reviewer asked only to check “source of protein” should be told if marketing later adds a body-function statement. Other claims such as gluten-free, fibre or low sugar have their own conditions; success on the protein question does not resolve them.

Record the claim decision before artwork is released

Bring the wording, evidence and current panel together in a short decision record. State what was assessed, the applicable condition, the product and serving basis, evidence considered, unresolved items and the person responsible for the business’s release decision.

Standard 1.2.8 on nutrition information sets out panel requirements, including protein quantities per serving and per unit quantity. Claims can also affect nutrition-information obligations for some otherwise exempt foods. Do not assume an earlier exemption remains unchanged after a claim is added; small packages and other specific situations need the appropriate check.

1. Confirm the precise product, claim and market covered by the review.
2. Resolve the relevant amount, descriptor and product-form questions using matching evidence.
3. Compare the complete revised proof with the assessed wording, panel and directions.
4. Keep the final artwork version and review record together, with a clear business release decision.
5. Reopen the affected assessment after changes to formulation, ingredient supply, yield, serving, directions or marketing wording.

Avoid common protein-claim review mistakes

• Using a per-100 g figure as if it were the protein in one serving.
• Treating required protein information in a panel as a voluntary marketing claim.
• Applying only the general condition to wording with a stronger specific meaning.
• Relying on a supplier’s ingredient claim without assessing the finished food.
• Changing preparation directions or serving information without checking the claim basis.
• Adding health or performance wording after a content-only review.

Frequently asked questions about protein claims

Commission a focused protein-claim review

AFVA’s food labelling review service includes nutrition panels, servings information and claims such as high protein. Send the current formulation, nutrient evidence, serving and preparation details, exact proposed claim and complete artwork. Explain whether you need a content-claim review or a wider review including health wording.

General information only: requirements depend on the product category, formulation, food form, claim wording, package, sales format and market. The suggested evidence and release workflow is practical guidance, not official approval, a laboratory protocol or a complete legal checklist. Confirm the requirements for the actual product using the current Food Standards Code and appropriate advice.
