No — you cannot legally connect a gas dryer to the gas supply yourself in New Zealand. Connecting any appliance to a gas line is restricted work under the Gas Act 1992, and must be carried out by a licensed gasfitter registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB). Doing this work yourself — or hiring an unlicensed person — is illegal, potentially dangerous, and could void your home insurance.
Why Gas Connection Is Restricted Work
Under New Zealand law, restricted gas work includes any task that involves connecting, disconnecting, or altering a gas installation. This covers:
- Connecting a flexible hose or rigid pipe from the gas supply to your dryer
- Installing or relocating a gas isolation valve
- Modifying existing gas pipework to accommodate a new appliance
- Commissioning and testing the gas connection for leaks
The PGDB licenses and regulates gasfitters in NZ. Only a certifying gasfitter can issue the Certificate of Compliance (CoC) required after completing restricted gas work. Without a CoC, your installation is not legally compliant, and your insurer may decline any claim arising from a gas-related incident.
What You Can Do Yourself
While the gas connection itself is off-limits, there are tasks a homeowner can legally handle:
- Positioning the dryer in the desired location
- Connecting the exhaust duct (the flue or vent hose that expels moisture and combustion gases outside)
- Plugging in the electrical cord to a standard power outlet (the dryer's power cord connection is not restricted electrical work)
- Levelling the appliance using adjustable feet
However, if your laundry space requires a new power outlet or any new electrical wiring, that work is restricted electrical work and must be done by a registered electrician — check the Electrical Workers Registration Board (EWRB) to verify a sparky's licence.
Venting and Building Code Considerations
Gas dryers must be correctly vented to the outside to safely remove combustion gases and moisture. Poor venting can cause carbon monoxide build-up — a serious health risk. Under the NZ Building Code, clause G4 (Ventilation) sets requirements for gas appliance installations — check with your gasfitter and local council for the specific regulations governing gas appliance venting.
Key venting points to discuss with your gasfitter:
- The vent must terminate outside the building, not into a wall cavity or roof space
- Vent runs should be as short and straight as possible
- The correct flue diameter and material must match the manufacturer's specifications
If new penetrations through an external wall are needed, check with your local council whether a building consent is required. Many minor appliance installations fall under Schedule 1 exemptions, but it's always worth confirming — requirements can vary by council.
The Risks of DIY Gas Work
Attempting to connect a gas dryer yourself carries serious risks:
| Risk | Potential Consequence |
|---|---|
| Gas leak | Fire, explosion, carbon monoxide poisoning |
| Incorrect appliance rating | Incomplete combustion, appliance damage |
| No Certificate of Compliance | Insurance claims declined, illegal installation |
| Fines and penalties | Prosecution under the Gas Act 1992 |
WorkSafe NZ takes gas safety seriously, and incidents involving unlicensed gas work can result in significant legal consequences for homeowners.
What to Expect From a Licensed Gasfitter
When you hire a licensed gasfitter to install your gas dryer, they will typically:
- Assess your existing gas supply — checking pressure, pipe sizing, and capacity
- Connect the appliance using an approved flexible connector or hard pipe
- Install an isolation valve if one isn't already present
- Pressure-test the connection for leaks
- Commission the appliance — checking ignition, flame quality, and combustion
- Issue a Certificate of Compliance — your legal proof the work was done correctly
As a rough guide, a straightforward gas dryer connection (where gas is already available nearby) might take one to two hours. Always get a written quote beforehand.
Choosing the Right Tradesperson
Always verify your gasfitter's licence on the PGDB website before work begins. You can search their register online to confirm the person is currently licensed and authorised to carry out certifying work.
You can find qualified, local licensed gasfitters on tradedirectory.co.nz — it's a great starting point for getting a few quotes and checking reviews from other NZ homeowners.
When to Call a Professional
Call a licensed gasfitter for any of the following:
- Connecting your gas dryer to the gas supply (always required)
- Relocating or extending gas pipework
- If you smell gas at any point — leave the house, don't operate switches, and call 0800 111 777 (Gas Emergency) or your gas retailer immediately
- Decommissioning an old gas appliance
For electrical work related to the installation, contact a registered electrician. For questions about building consents, contact your local council.
