The Environmental Protection Authority (EPA) is the government agency responsible for regulatory functions concerning New Zealand's environmental management. This includes regulating the introduction and use of hazardous substances and new organisms under the Hazardous Substances and New Organisms (HSNO) Act 1996.
In June 2012, EPA approved amendments to the Cosmetic Products Group Standard. Group standards are approvals for a group of hazardous substances of a similar nature, type or use and this group standard is closely based on European Union (EU) legislation. The amendments include aligning the definitions of some cosmetic products with EU legislation and requiring manufacturers to provide batch and source code information on cosmetic labels, helpful for identifying products subject to a recall. The amended standard requires that, as of 1st July 2015, the presence of nanomaterials in cosmetic products available in New Zealand must be identified on labelling. In addition, any person intending to import or manufacture a cosmetic product containing nanoparticles other than zinc oxide or titanium dioxide must, at the time they first import or manufacture the substance, notify the EPA using the form provided on the EPA website. A list of nanomaterials which have been notified to the EPA is available here.
