The Energy Efficiency (Energy Using Products) Regulations 2002 establish mandatory minimum energy performance standards (MEPS), energy labelling requirements, and testing procedures for specified energy-using products supplied or imported into New Zealand. The Regulations identify product classes subject to performance standards and mandatory labelling, prescribe testing methodologies based on recognised national and international standards, and require manufacturers, importers, and retailers to ensure compliance through registration, testing, labelling, and information provision. They prohibit the sale of non-compliant products, establish energy rating and star-labelling systems for key appliances, and provide exemptions and transitional arrangements for certain products and circumstances. Enforcement is administered by the Energy Efficiency and Conservation Authority (EECA), which may require test reports and statistical information, while offences are subject to penalties and compliance measures.
