Why checking a gasfitter matters in NZ
Gas work is not the kind of job you should leave to guesswork. In New Zealand, gasfitting is a regulated trade because poorly installed or repaired gas appliances, pipework, flues, and fittings can create serious risks including gas leaks, fire, carbon monoxide exposure, and explosions.
A properly qualified and licensed gasfitter should know how to work safely, follow the relevant standards, and provide the paperwork you may need for insurance or future property sale. If you hire someone who isn’t authorised, you could end up with unsafe work, no valid record of the job, and potentially a problem with your insurer or council if the work needed compliance checks.
What a gasfitter licence means in New Zealand
In NZ, gasfitting is restricted work under the Plumbers, Gasfitters, and Drainlayers Act 2006. That means a person must be appropriately licensed to carry out gasfitting work, unless they are working under direct supervision where that is legally allowed.
The key regulator is the Plumbers, Gasfitters and Drainlayers Board (PGDB). The PGDB keeps the public register of licensed practitioners and sets the competence and conduct standards for the trade.
A legitimate gasfitter will usually have:
- a current gasfitting licence issued through the PGDB
- a valid photo ID/licence card from their profession
- the right class of licence or limited certificate for the specific work
- experience in the type of gas system you have, such as natural gas, LPG, hot water, heating, or cooking appliances
Restricted work vs general handyman work
Gasfitting is not general maintenance. A handyman, builder, plumber, or appliance installer may do some related tasks only if they are properly licensed for gas work and the job falls within their authorisation.
If the work involves gas pipework, connecting or altering gas appliances, commissioning gas systems, or work on flues and safety devices, you should assume it needs a licensed gasfitter unless you have checked otherwise.
How to verify a gasfitter is licensed
There are a few simple checks you should make before work starts. Don’t rely only on a website, social media profile, or a recommendation from a neighbour.
| Check | What to look for | Why it matters |
|---|---|---|
| PGDB public register | Name, licence type, status, and whether the licence is current | Confirms they are recognised by the regulator |
| Licence card / ID | Photo, name, licence number, and profession | Helps confirm the person attending is the licensed individual |
| Business details | NZ Business Number, trading name, contact details, GST number if applicable | Reduces the chance of dealing with a fake or untraceable operator |
| Written quote | Clear scope, exclusions, price, and timeline | Makes it easier to compare quotes and avoid disputes |
| Job paperwork | Certificate, compliance record, or other documentation after the job | Evidence the work was done properly and legally |
1) Check the PGDB register
The most important step is to search the PGDB public register. You can check whether the gasfitter is currently licensed, what class of licence they hold, and whether there are any conditions or disciplinary issues listed.
When you search, confirm:
- the person’s full name matches the person you’re actually hiring
- the licence is current, not expired
- the licence class is suitable for the work you need
- the registration status is active
If a business sends a different person on the day, ask to see that individual’s licence as well. A company name alone does not prove the worker attending your home is licensed.
2) Ask for the licence number and photo ID
A professional gasfitter should be comfortable showing their licence card and giving you their licence number. Compare the name and photo with the person at your door.
Be cautious if someone:
- hesitates to show ID
- gives a vague answer about their credentials
- says they are “in the process” of being licensed
- tells you the job is “too small to need a licence”
For gas work, that is usually a red flag.
3) Ask what kind of work they are licensed to do
Not every licence covers every gas job. Some practitioners may have limited scopes or be more experienced in certain areas, such as appliance servicing versus installation or pipe alterations.
Ask direct questions like:
- Are you licensed for this type of gasfitting work?
- Do you work on LPG, natural gas, or both?
- Have you installed this appliance brand or type before?
- Will you provide the required documentation when the job is complete?
A competent gasfitter should answer clearly and without defensiveness.
What qualifications and experience should you look for
Licensing is the first filter, but experience matters too. Gasfitting often involves older homes, mixed fuel systems, older appliances, or tight retrofits where workmanship counts.
Look for a gasfitter who can show:
- a current licence in good standing
- relevant apprenticeship or trade training
- practical experience with your type of job
- knowledge of safety clearances, ventilation, flues, and appliance commissioning
- familiarity with NZ standards and manufacturer instructions
If the work is part of a larger renovation, it’s even more important they can coordinate with plumbers, builders, or electricians where needed.
Signs a gasfitter may not be properly licensed
You should walk away if you see any of these warning signs:
- they cannot produce a licence number or card
- they are not listed on the PGDB register
- they offer a much lower price than every other quote without explaining why
- they suggest skipping paperwork or “keeping it off the books”
- they say they can do gas work because they are a builder, plumber, or appliance technician, but cannot show the right licence
- they refuse to put the quote in writing
Unlicensed gas work may seem cheaper upfront, but it can become very expensive if you have to pay to have it inspected, corrected, or completely redone.
What paperwork should you get after the job
The exact documentation depends on the job, but you should always expect proper records rather than just a verbal “all good”. For gasfitting work this may include:
- an invoice clearly showing the business name and licence holder
- details of the work completed
- any test results or commissioning information where relevant
- evidence that the appliance or installation was checked for safe operation
- any compliance documentation required for the specific work
Keep these records with your house documents. They can be useful for insurance claims, rental inspections, or when you sell the property.
Do you need council consent for gas work?
Usually, the gasfitting itself is regulated through the PGDB rather than through a building consent, but some related renovation work may need other approvals.
For example, you may need to involve your local council if the job includes:
- structural changes
- significant alterations to a kitchen or laundry layout
- new flue penetrations or building work affecting the roof or exterior wall
- work that forms part of a larger renovation requiring building consent
If you’re not sure, ask the gasfitter and check with your local council before the work starts. A good tradie will tell you when another trade or approval is needed.
How to compare quotes from gasfitters
Once you’ve confirmed the licences, get at least two or three written quotes. In NZ, price alone shouldn’t be the deciding factor.
Compare:
- whether the quote includes labour, materials, call-out fees, and GST
- whether removal of old equipment is included
- whether the quote covers testing and commissioning
- likely timeframes, especially in winter when heating jobs are busier
- warranty terms on workmanship and parts
Gas heating, hot water, and cooking jobs often become urgent during colder months, so book early if you’re planning winter maintenance or a replacement.
What to ask before you hire
A short phone or email checklist can save a lot of trouble later:
- Can you provide your PGDB licence number?
- Is your licence current and suitable for this job?
- Will you do the work yourself, or send someone else?
- Have you completed similar jobs in homes like mine?
- What documentation will I receive when the job is finished?
- Does your quote include GST, parts, and travel if applicable?
If they answer clearly and provide evidence, that’s a good sign. If they dodge the questions, keep looking.
Why this is especially important for rental properties and older homes
If you own a rental, you have an extra incentive to use a properly licensed gasfitter. Tenancy obligations and healthy homes-related issues can make safe heating and hot water systems especially important, and you’ll want clear records if a tenant reports a fault.
Older NZ homes can also present extra challenges:
- ageing gas lines or fittings
- non-standard past alterations
- outdated appliances
- limited space for compliant installation
- flueing and ventilation issues
These homes often need a more experienced gasfitter who understands both safety and practical retrofit work.
A simple hiring checklist
Before you book the job, make sure you can tick all of these off:
- The person is listed on the PGDB register
- Their licence is current and matches the work
- The name on the licence matches the person attending
- You have a written quote
- You understand what is included and excluded
- You know what paperwork you’ll get when the job is done
- Any related council or building-consent issues have been checked
The bottom line
Checking a gasfitter’s licence in New Zealand is straightforward, and it’s one of the best ways to protect your home, your family, and your wallet. Use the PGDB register, ask for ID, confirm the licence suits the job, and compare a few written quotes before you choose.
If a tradesperson is fully licensed, experienced, and happy to answer questions, that’s exactly the sort of person you want working on gas in your home.
