Certification is a requirement under Section 55 of the Gas (Safety and Measurement) Regulations 2010.

The Gas (Safety & Measurement) Regulations 2010(external link) (GSMR) set out the obligations for people supplying gas products in New Zealand. Both the 2010 regime and the 2025 updates to the cited standards set out requirements for the supplier (importer/New Zealand manufacturer) of any gas appliance imported or New Zealand manufactured after 1 July 2013.

Unless the appliance has been endorsed, the following criteria must be met:

• The gas appliance must be certified in accordance with Schedule 2A(external link) of the GSMR as amended by the 2025 regulatory amendment.
• The safety compliance label (flame logo) must be attached to the appliance.
• The appliance must be marked with certain data, including a means to identify the company making the supplier declaration. This can be, for instance, the trademark or name of the supplier (importer/NZ manufacturer).
• The supplier must register and make a supplier declaration of compliance (SDoC) on the declaration database(external link).
• A copy of the certification issued by the certification body must be attached to the SDoC. Schedules must also be included (Note: a Declaration of Conformity from the appliance manufacturer or a reference to it in a product manual is not acceptable).
• The SDoC must list the fuel gas or gases the appliance can safely use and the corresponding fuel gas or gases it has been certified to.
• The appliance has installation instructions(external link) that, when followed, will ensure the appliance complies with the GSMR and is safe.
