Appliance installations (gas cooktops, hot water systems, heaters)
Planning a renovation, installing new appliances, or switching to gas? Get it done right—contact the team at Tuffnell Plumbing Drainage & Gas.
Switching from electric to gas appliances
Installing a new gas cooktop, water heater, or fireplace? A qualified gas fitter is needed to install the appliance, connect gas lines, and complete safety checks.
Smell of gas near appliances or gas bottles
A strong odour near the gas meter, bottle, or inside the kitchen could be a sign of a gas leak. This should be treated as urgent—shut off the supply and arrange an inspection immediately.
Flames burning yellow instead of blue
Gas burners with orange or yellow flames may be burning inefficiently or unsafely. This can be caused by poor airflow, blockages, or incorrect pressure settings.
Hot water system or cooktop keeps cutting out
When appliances won’t stay lit or keep shutting off, there could be a fault with the regulator, valves, or gas pressure. These issues should be checked by a licensed gas technician.
Old or corroded gas pipes in the home
Older copper lines or visible corrosion around pipe fittings can lead to leaks and failures over time. Any gas system older than 15–20 years should be inspected and pressure-tested.
Building work near existing gas lines
Renovations in kitchens, bathrooms, or laundries often involve moving or disconnecting gas fittings. Altering or extending gas lines legally requires a licensed gas fitter to carry out and certify the work.
A licensed gas installation isn’t just about ticking a compliance box—it directly affects the performance, safety, and long-term reliability of every appliance that runs on gas. Poor installations cause pressure problems, inefficient burning, and serious hazards like leaks or carbon monoxide buildup. Certified gas fitting prevents these issues from the start.
Here’s how certified gas fitting is carried out—from start to finish:

Installing a single gas appliance—like a cooktop or freestanding heater—typically ranges from $400 to $800, depending on access, appliance type, and distance to the existing gas line. If new pipework or regulators are required (common in first-time installs), costs can increase to $1,000–$2,000. A full gas fit-out for a home can range between $2,000 and $5,000+.Installing a single gas appliance—like a cooktop or freestanding heater—typically ranges from $400 to $800, depending on access, appliance type, and distance to the existing gas line.

LPG (liquefied petroleum gas) is delivered in bottles and is more common in rural or off-grid properties. Natural gas is piped directly into homes through a meter connection. The appliances, pressure regulators, and fittings differ slightly. It’s important to install appliances and pipework matched to your supply type—something only a certified gasfitter can assess and install correctly.
Yes. All gas work in NZ must be completed by a licensed gasfitter and signed off with a Gas Safety Certificate (Certificate of Compliance). This proves the system meets AS/NZS 5601.1 standards and is legally required for insurance, tenancy, or resale purposes.
No. It’s illegal and unsafe to install or disconnect any gas appliance yourself in New Zealand—even if the fittings are already in place. This includes cooktops, heaters, hot water systems, and BBQ bayonets. Only a licensed gasfitter can carry out and certify this work.
Common signs include a strong sulphur or rotten egg smell, hissing sounds near pipework, pilot lights blowing out, or burners burning yellow instead of blue. If you suspect a leak, turn off the gas supply at the meter or bottles and call a certified gasfitter immediately.
