Why Gas Fitting Must Always Be Done by a licensed gasfitter

DIY projects can be a great way to save money and feel proud of your handiwork. But when it comes to gasfitting, this is one job that should never be done by yourself.

In New Zealand, it’s actually illegal to carry out any gasfitting work if you’re not a licensed gasfitter. That includes installing, altering, or repairing appliances and pipework. The law exists to protect people, because gas is something that needs expert knowledge and testing to be handled safely.

Here’s why it’s important to leave gasfitting to the professionals:

1. Risk of Gas Leaks & Explosions
Gas leaks are one of the biggest dangers of incorrect installation. Even a small mistake like a loose connection can cause a serious fire or explosion.

2. Carbon Monoxide Safety
Gas appliances that aren’t installed correctly can produce carbon monoxide, an invisible and odourless gas that can make people very sick and, in the worst cases, be fatal. A licensed gasfitter knows how to install and test appliances so they run cleanly and safely.

3. Insurance & Warranty Protection
Most insurance policies and manufacturers’ warranties require gas appliances to be installed by a licensed gasfitter. If you DIY, you risk voiding your cover, which could leave you without protection if something goes wrong.

What You Can Do Yourself

Not all parts of the process need a professional.

Here’s what you’re allowed to do:

• Buy your own gas appliance
• Arrange delivery to your home
• Prepare the space (like cabinetry, ventilation, or flooring)
• Book a licensed gasfitter to carry out the installation

✅ The takeaway: While DIY is great for many home projects, gasfitting isn’t one of them. By law and for your safety it’s a job that must be done by a licensed gasfitter.

That way you’ll also have peace of mind knowing your appliance is safe, efficient, and fully compliant.
