The smell of gas in your home is something you should never ignore. Natural gas and LPG are both odourised so you can detect gas leaks — that distinctive rotten egg smell is there for your safety.
If you smell gas right now — follow these steps immediately.
5 Steps to Follow
Do Not Create Any Sparks
Do not turn light switches on or off. Do not use electrical appliances. Do not use your phone indoors. Do not light matches or candles. Do not start your car in an attached garage.
Ventilate
Manually open doors and windows to let the gas dissipate. Do not use electrical ventilation systems like rangehoods or extractor fans.
Turn Off the Gas Supply
Locate your gas meter and turn the valve to the off position. If you're not sure where it is, get out of the house first and call an emergency plumber.
Get Everyone Out
Evacuate all people and pets from the property. Move well away from the building.

Common Causes of Gas Leaks
- Faulty appliances — old or poorly maintained gas heaters, hobs, and califonts (including older hot water systems)
- Damaged gas pipes — corrosion, ground movement, or accidental damage during renovations
- Poor connections — DIY work or unlicensed installation of gas appliances (always use a certified gas fitter)
- Regulator issues — faulty or aging gas regulators on LPG bottles or mains connections
How to Prevent Gas Leaks
- Service your gas appliances regularly — at least every two years. WorkSafe NZ recommends regular maintenance for all gas installations
- Keep your gas compliance certificates current — required by law for any gas work
- Know your system — know where your gas meter and shutoff valve are
- Install a gas detector — especially if you have gas heating or cooking
