We can maintain and install gas appliances to code regulations, this includes gas hot water cylinders, fires, gas heaters and ovens or hobs. It is possible to install gas appliances into new and existing houses using natural gas or LPG bottles. Natural gas is only available if that service is offered in your street however.
Before you buy a gas appliance you should check that it is listed on the Energy Safety website's Supplier declaration database. If it has a supplier's declaration then it is approved for installation and use in New Zealand (by a qualified gasfitter).
