What Gas Certification Includes
- Verification of manufacturer compliance — the appliance must be NZ-approved usually on the Gas appliance database.
- Installation and testing to NZS 5601 parts 1 & 2 2013
- Pressure test of the complete installation, this is a pipe work and appliance gas pressure test to ensure gas is not leaking.
- Commissioning to manufacturer instructions — flame picture, pressure drop, flue updraught.
- Full safety check — clearances, ventilation, isolation valves, flue operation.
- Customer instruction on safe appliance use
- Gas Safety Certificate issued within 20 working days.
- PS3 Producer Statement, or Gas Certificate and Energy Work Certificate given to the local authority where a Building Consent is issued for Building Consent jobs.
Before You Buy a Gas Appliance — Check Compliance
Many imported and auction-site gas appliances do not meet NZ standards — and legally cannot be certified here. That means a shiny new hob from overseas might be unusable once it arrives.
Quick compliance checklist:
- Is the appliance registered with the Energy Safety Database?
- Does it carry an Australian/NZ gas appliance approval sticker?
- Is it matched to your gas type (NG or LPG) — or convertible?
- If second-hand — does it actually go and is it complete and have operating instructions?
Call 0800 484 353 before you commit and we’ll check for you.

How Safe Is Gas, Really?
Gas is a safe energy source when it is well maintained.
Keep it that way:
- Service appliances every 2 years minimum. Link
- Keep flammables away from gas hot water cylinders
- Check flues are un-corroded and venting freely
- Keep ventilation grills clear and not covered with furniture.
- Watch for yellow flame tipping — call us if you see it. Flame effect gas fires are designed to have yellow tipping.
