Before gas appliances and specified fittings can be offered for sale in New Zealand, they need to be certified by a recognised certification body or certification regime. Certification is a requirement under Section 55 of the Gas (Safety and Measurement) Regulations 2010.

Gas (Safety and Measurement) Regulations 2010(external link)

The following bodies may certify gas appliances and specified fittings:

  • A body working within the European Directive for gas burning appliances – EU Directive 2009/142/EC or EU Directive 90/396/EC.
  • Canadian Standards Association or Underwriters Laboratories to a specified Canadian or ANSI Standard, under specified conditions.
  • SAI Global, IAPMO, Australian Gas Association or Global-Mark to a specified Australian Standard, under specified conditions.
  • A body accredited by the Joint Accreditation System of Australia (JAS-ANZ) and with a scope that includes NZS/AS 3645:2010 Part 2.

The regulations also apply to gas appliances and fittings that are imported as part of an installation, such as a caravan.

Exceptions are for gas appliances or fittings endorsed under Regulation 57(external link) or gas appliances with design capacity to consume 60 000 megajoules or more of gas energy per hour.

All certified appliances are also required to be covered by a Supplier Declaration made by the New Zealand manufacturer or importer, and lodged on the gas appliance database on the Energy Safety website. 

More information about these bodies can be found in Schedule 2A(external link) of the Regulations, along with relevant standards and conditions for certification.
