NZS 5261:2003

Legislative changes in 1992 removed the responsibility for inspection and certification of gas installations from the gas suppliers and instituted a regime of gas certification by a person authorized under the Plumbers, Gasfitters and Drainlayers Act. This Standard in Part 1 details the various aspects of a gas installation that contribute to its safety, stating performance criteria that shall be achieved to ensure that the legislative requirements for safety of gas installations are met. Part 2 gives the gasfitter more detailed information as a means of compliance with these performance criteria for small installations, and Part 3 gives references for use in the design and specification of larger installations. The means of compliance in Parts 2 and 3 are not the only means of compliance with the performance criteria in Part 1. Gas installations should be undertaken by persons authorized under the Plumber Gasfitters and Drainlayers Act 1976.
