Gluten-Free Claims NZ: Ingredient Checks Before Testing

For gluten-free claims in NZ, start with the ingredients—not just a request for a laboratory result. The Food Standards Code includes restrictions on particular ingredients as well as a condition about detectable gluten.

This guide helps ordinary packaged-food businesses prepare an ingredient brief before testing and artwork decisions. It is not a complete label assessment or testing protocol. Use our food labelling requirements checklist for the wider review, and our allergen declaration guide for mandatory allergen information.

Gluten-free claims NZ: check the ingredient restrictions

Standard 1.2.7, section 1.2.7—12 connects nutrition content claims with the applicable Schedule 4 conditions. Using a synonym of a listed descriptor does not avoid those conditions.

Under the gluten “Free” entry in Schedule 4, section S4—3: conditions for nutrition content claims, the food must not contain:

• detectable gluten;
• oats or oat products; or
• cereals containing gluten that have been malted, or products of those cereals.

These are separate restrictions. Our practical recommendation is to resolve the ingredient questions first, rather than treating a test result as a way around an excluded ingredient.

Prepare an ingredient brief that matches the recipe

The following is a recommended preparation worksheet, not a statutory form. Work from the recipe and specifications for the ingredients actually proposed for production. Ask suppliers to resolve missing information rather than recording an assumption as a confirmed answer.

On a small screen, swipe sideways to view all columns. Keyboard users can focus the table region to scroll.

For a description such as “malt” that leaves the source unclear, ask which cereal was used and whether the ingredient is a product of a malted gluten-containing cereal. Keep the supplier’s answer with the matching specification.

Check declaration exemptions separately

The wheat-starch glucose-syrup exemption illustrates why the distinction matters. Schedule 9, section S9—3: wheat declaration exemptions requires both refining that removes gluten protein to the lowest reasonably achievable level and a gluten protein content not exceeding 20 mg/kg. Evidence addressing only one condition is incomplete.

FSANZ’s explanation of allergen declaration exemptions and gluten-free claims expressly says the exemptions do not change gluten-free requirements. It explains that a glucose syrup cannot itself be labelled gluten free if detectable gluten is present.

Bring product-specific questions to the laboratory

Once the ingredient screen is resolved, take the formulation, process description, supplier evidence and existing reports to an appropriate laboratory and adviser. Suggested briefing questions are:

• Which analytical method is suitable for this product and its processing?
• What do “not detected”, the detection limit and the reporting limit mean on the proposed report?
• Which ingredients, batches and production conditions would the evidence address?
• What existing validated product or process evidence is relevant, and what gaps need testing or further investigation?
• What information is needed about possible unintended gluten presence during manufacture?

These are discussion questions, not a validated testing procedure. This article does not prescribe sample numbers, testing intervals or a universal analytical limit. Nor does it establish that paperwork can replace testing needed to substantiate the claim.

A practical decision checklist before artwork release

We recommend the following sequence:

1. Identify the product. Match the recipe, supplier specifications and proposed claim wording.
2. Resolve restricted ingredients. If an ingredient restriction applies, do not rely on testing to rescue the claim.
3. Close supplier-information gaps. Keep an unanswered cereal-source or exemption question open until evidence resolves it.
4. Complete the evidence assessment. Agree the product-specific testing and other supporting evidence needed.
5. Reconcile the label. Review the claim alongside the required declarations and wider label requirements before authorising artwork.

Keep the decision and its supporting documents together. Reopen the review when a recipe, ingredient specification, supplier or manufacturing process changes.

Common mistakes to avoid

• Starting with a test booking: first establish whether the ingredients permit the claim.
• Treating “exempt” as a complete answer: identify the declaration exemption and assess the claim separately.
• Reviewing only the top-level recipe: request component information for bought-in mixtures.
• Keeping an unexplained result: ask the laboratory what its terminology and limits mean for the intended assessment.

How AFVA can help with the label review

AFVA’s food labelling review service covers ingredient lists, allergen declarations and claims such as gluten free, including comments on possible compliance risks or evidence requirements. The support described here is label-review consulting only—not official label approval or an offer of evaluation or verification.

AFVA provides review comments and practical recommendations; final responsibility for label compliance remains with the food business. For an enquiry, prepare your recipe, specifications, proposed wording and existing evidence.

Resolve the recipe questions before relying on the result

Use the ingredient brief to separate restrictions, declaration exemptions and analytical evidence. Give each unresolved question a clear owner and keep the claim decision on hold until the supporting assessment is complete.

General information only: Requirements depend on the complete food activities, products, processes, locations and sales model. Use current official guidance and confirm the requirements applying to the specific business before relying on a classification, timeframe or record list. This ingredient-screening guide does not replace a complete product-specific label and claim assessment.
