About ESR's food & product services

ESR employs the largest group of microbiologists in New Zealand to provide you with the full spectrum of food science expertise – from identifying a foreign object in food through to food import and export certification. No one else in the country undertakes a broader or deeper range of research and investigation into food safety, quality and authenticity.

ESR’s GMP-certified pharmaceutical programme analyses medicines, cosmetics, natural health and other therapeutic-like products for local manufacturers and importers of international products, to determine what exactly is in the product. We also provide a secure, dedicated Stability Facility for product storage and testing of expiration dates.
