The rapid growth of gluten-free food innovation has transformed supermarket shelves.
Products once limited in quality and variety are now more diverse, nutritious, and appealing. Alongside these advancements comes a critical responsibility: ensuring gluten-free labelling is accurate, consistent, and safe for people living with coeliac disease.
Coeliac disease affects an estimated 100,000 New Zealanders. For those affected, strict lifelong avoidance of gluten is essential medical treatment. Even trace exposure can cause harm, making clear labelling, strong compliance systems, and ethical sourcing practices just as important as the products themselves.
A Timely Reminder: Coeliac Awareness Week (15 – 21 June 2026)
Coeliac Awareness Week 2026 highlights the important role supermarkets play in supporting customers managing coeliac disease. This responsibility extends beyond food to all customer touchpoints, including in-store pharmacies.
Gluten may also be present in medicines and vitamins, creating an often-overlooked risk. Supermarket buyers are therefore uniquely positioned to guide customers toward safe options and help prevent accidental exposure - particularly in supermarket bakeries and deli sections. This reflects not only compliance, but an ethical commitment to customer wellbeing.
Complex Supply Chains and Ethical Sourcing
Modern gluten-free products often include a wide range of alternative flours, functional ingredients, and additives. While these innovations improve taste and texture, they also increase ingredient complexity.
Ethical sourcing and accurate labelling are essential. Supermarkets must ensure ingredients are sourced from suppliers with strict segregation, testing, and traceability systems. Without this, contamination risks can arise long before products reach shelves.
Ethical sourcing also requires transparency and accountability, particularly for imported products. A gluten-free claim must be supported by robust systems that ensure accuracy at every stage of production.
