Every person who manufactures, imports, sells or offers for sale, hires out, leases out, or installs a gas appliance or fittings must ensure as far as reasonably practicable that the gas appliance or fittings are safe. This applies to appliances and fittings whether new or used, or imported as part of an installation such as a caravan.
While there is a general requirement under the Gas (Safety and Measurement) Regulations 2010(external link) for all gas products to be safe, the New Zealand regulatory environment establishes the limits of fundamental safety. The Regulations specify aspects of the gas appliance design and construction that are not permissible, e.g. deemed to be unsafe.
These aspects identified as being unsafe are also used as the basis for enforcement, including prohibition.
Gas appliances must be safe when used with the gas for which they are intended. This is typically either natural gas, which must conform to NZS 5442, or LPG, which must conform to NZS 5435.
Note: the characteristics of the gases supplied in New Zealand differ from those used in many other countries.
The fundamental requirements for the gas product regime. This includes who must comply, transitional arrangements, and compliance.
Gas Appliance Supplier Declarations of Compliance
The importer or New Zealand manufacturer of a product of a type covered under the certification regime is required to make a Supplier Declaration of Compliance (SDoC) before they supply the product. Specified fittings and declared articles may also require an SDoC.
The Certification regime provides recognised four equivalent certification regimes.
Safety compliance labels
Regulatory requirements for the gas appliance compliance label.
Endorsement regime and approved practitioners
Endorsement of gas appliances and specified fittings that may not otherwise meet the requirements of the regulations for certification.
