Khandallah homes

Over three times the national rate

A fixed gas heater was a main heating type in 33.1% of Khandallah dwellings in 2023, against 9.5% across New Zealand. "Other types of heating" was 14.2%, and wood burners only 13.8%.

Larger houses

36.1% of homes had four bedrooms (24% nationally), and just 13.4% had two.

Family trusts

Of 3,126 occupied homes, 59.7% were owned by the household and 18.8% held in a family trust, well above the 11.1% national figure. Only 21.4% did neither.

Few new builds

Stats NZ counts 4 new dwellings consented in the year to March 2024, 12 in 2025 and 10 in 2026, so most work here is on existing homes.

Gas work and its paperwork

All gasfitting is restricted work, so only an authorised gasfitter may install, move or connect fixed gas pipes and appliances. A restricted gasfitter can't connect an appliance to the supply. When the work is finished and connected, the person who connected it issues a Gas Safety Certificate if satisfied it's safe. Installing a new appliance or altering pipework also needs a gas Certificate of Compliance; for low-risk like-for-like swaps it's optional.

Smell gas? WorkSafe says a problem with the supply goes to your gas retailer and a problem with your installation or appliances goes to a licensed gas worker. After an earthquake, WREMO says to open a window, get everyone out and turn the gas off if you can. In an emergency, dial 111.

Water and drains

Tiaki Wai treats the lateral, from your house to the public wastewater network, as the owner's responsibility, and a blocked gully trap is a plumber's job. Faults in the street go to 0800 TIAKI WAI (842 549). There's no published toby rule for Wellington City, so ask Tiaki Wai where its pipe ends.

What we would do

After any gas job in your Khandallah home, ask for the Gas Safety Certificate, and the Certificate of Compliance if the work was more than a like-for-like swap, before the gasfitter leaves. Keep both with your house papers. They show the work was done by an authorised person and checked as safe, which matters to insurers and to anyone who buys the house later.

Questions people ask

Can I swap my own gas heater in Khandallah?

No. Connecting a fixed gas appliance is gasfitting, which needs an authorised gasfitter. Portable bottle gas heaters aren't gasfitting, so they don't need one.

Do I always get a Certificate of Compliance for gas work?

Not always. A Gas Safety Certificate is needed for all gasfitting once it's connected. A Certificate of Compliance is required for general and high-risk work, such as a new appliance or altered pipework, but optional for low-risk like-for-like replacements.
