Why choosing the right gasfitter matters Gasfitting is not a job to leave to guesswork. In New Zealand, gasfitting is restricted work, which means it must be done by, or under the supervision of, a properly authorised person. A good gasfitter does more than connect appliances: they make sure the work is safe, compliant, and suitable for your home.
That matters whether you are installing a new gas hob, replacing a continuous-flow hot water system, servicing a gas fire before winter, or converting part of a property to bottled gas. Poor workmanship can cause leaks, carbon monoxide risks, appliance faults, insurance issues, and expensive rework.
If you want peace of mind, start by choosing a gasfitter as carefully as you would choose a plumber, electrician, or builder.
What a good gasfitter looks like A reliable gasfitter is usually easy to identify once you know what to look for. They should be able to explain the job clearly, answer questions without being vague, and give you confidence that they understand both the appliance and the installation.
Look for these signs:
- They are properly licensed or authorised for gasfitting work in New Zealand. - They ask detailed questions about your current setup, appliance type, location, and whether the work is for natural gas or LPG. - They provide a written quote that explains labour, materials, any call-out fee, and GST. - They mention compliance, safety checks, and certification without being prompted. - They turn up when they say they will, or they communicate promptly if they are delayed. - They leave the site tidy and do not rush past safety issues. - They are happy to explain what work is included and what is not.
A good gasfitter will also tell you when another trade is needed. For example, some jobs may require a plumber, electrician, or builder as well, especially if cabinetry, ventilation, power, or pipe routing is involved.
Start with word of mouth Word of mouth is still one of the best ways to find a good tradesperson in New Zealand. Ask people whose judgement you trust, especially if they have recently had similar work done.
Good places to ask include:
- neighbours who have installed or upgraded gas appliances - friends or family in your area - your property manager, landlord network, or body corporate, if relevant - local builders, plumbers, or appliance retailers - community Facebook groups or local neighbourhood groups, if you use them carefully
When you ask for recommendations, be specific. “Can you recommend a gasfitter for a gas hob replacement in Wellington?” is more useful than “Do you know a gasfitter?” The closer the job and area match your own, the more helpful the recommendation.
Also ask what the experience was like:
- Did they arrive on time? - Was the quote clear? - Did the final invoice match the quote? - Did they tidy up and explain the handover? - Was there any follow-up required?
A glowing recommendation is useful, but a recent, detailed one is even better.
Check reviews, but read them properly Online reviews can help you short-list gasfitters, especially if you do not have strong word-of-mouth referrals. However, reviews are best used as a pattern, not a single verdict.
Look for:
- a steady stream of recent reviews rather than one burst years ago - comments about punctuality, communication, cleanliness, and professionalism - job-specific feedback, such as appliance installation, servicing, or emergency call-outs - responses from the business, especially where they have handled problems well
Be cautious if:
- all the reviews sound overly generic or repetitive - the only reviews are extremely short and vague - there are no recent reviews at all - complaints mention no-shows, surprise extras, or poor communication
Remember that a good tradesperson can still have an occasional unhappy customer. What matters is whether the overall picture is consistent and whether the gasfitter responds professionally.
Verify credentials before you book In New Zealand, gasfitting is regulated, and you should verify that the person you hire is authorised to do the work.
Before you accept a quote, ask for:
- their full name and business name - their registration or licence details for gasfitting work - evidence of current authorisation, if applicable - their GST number if they are GST-registered - proof of insurance, ideally including public liability cover
You can check licensing details through the relevant New Zealand regulatory system. For gasfitting, plumbing, and drainlaying, this is overseen by the Plumbers, Gasfitters and Drainlayers Board (PGDB). Do not assume that a tradesperson is qualified just because they say they are.
If the work involves anything electrical, such as a power connection for an appliance, that part must be done by a registered electrician or electrical worker authorised under the Electrical Workers Registration Board (EWRB) framework.
For building alterations, flue changes, cabinetry alterations, or structural work, a building consent from your local council may be needed. A competent gasfitter should tell you if another consent or trade is likely to be required, but they are not responsible for council approval unless that is specifically part of the job.
Use directories and trade platforms wisely Online directories can save time, especially if you are comparing several gasfitters in your region. They are most useful when they let you compare service areas, specialties, and basic business details in one place.
Good directories can help you find:
- gasfitters in your suburb, town, or region - businesses that service LPG, natural gas, or both - tradespeople who handle domestic, commercial, or emergency work - customer reviews in one place
However, do not treat a directory listing as proof of competence. Use it as a starting point, then check:
1. whether the business is local or regularly works in your area 2. whether the licence details match the person quoting 3. whether the website or listing explains the type of work they do 4. whether the contact details look professional and current
For New Zealand homeowners, local relevance matters. A gasfitter who regularly works in your region is more likely to understand local housing stock, LPG tank setups, rural access issues, and the common appliance brands used here.
Get at least two or three written quotes For non-emergency work, ask for multiple written quotes. This helps you compare not just price, but how each gasfitter approaches the job.
A useful quote should clearly show:
| What to check | Why it matters | |---|---| | Scope of work | So you know exactly what is included | | Labour and materials | To compare real cost, not just headline price | | GST | To avoid surprises when invoiced | | Call-out fee | Especially important for small jobs | | Compliance or certification fees | These may be included or charged separately | | Exclusions | So you know what is not covered | | Timeframe | Helps with planning and urgency | | Warranty or workmanship guarantee | Useful if something goes wrong |
Do not automatically choose the cheapest quote. A very low price can mean the gasfitter has missed part of the job, is using poor-quality materials, or plans to add extras later. On the other hand, the highest quote is not always the best either. The goal is value, clarity, and competence.
Questions worth asking before hiring A short conversation can tell you a lot about whether a gasfitter is professional.
Useful questions include:
- Have you done this exact type of job before? - Are you licensed to carry out the work yourself? - Will you provide a compliance record or certificate where required? - Do you work with natural gas, LPG, or both? - Is any other trade likely to be needed? - Do I need council consent for any part of this project? - What preparation do I need to do before you arrive? - How long will the job take? - What happens if you find an issue once you start?
A good gasfitter will answer clearly and not make you feel awkward for asking. If someone dismisses your questions or avoids specifics, that is worth taking seriously.
Red flags to watch for There are some warning signs that should make you pause and keep looking.
Be wary of a gasfitter who:
- cannot or will not provide licensing details - offers a price only verbally and refuses to put anything in writing - asks for a large cash-only payment upfront without reason - pressures you to decide immediately - seems uncertain about compliance or says permits and certificates are “not really needed” - recommends unsafe shortcuts, such as leaving out ventilation or using makeshift fittings - will not explain what brand or type of parts they plan to use - is vague about whether the work is for LPG or natural gas
Gas work should feel methodical, not improvised. If the job involves a combustion appliance, flues, ventilation, or a gas heater, you want someone who takes safety seriously rather than trying to finish as fast as possible.
Think about the job type and timing The right gasfitter for your job depends on what you need done and when you need it.
In New Zealand, demand often rises before winter as homeowners service gas fires, heaters, and hot water systems. If you leave it until the first cold snap, you may wait longer or pay a premium for urgent work. Plan ahead where possible, especially for:
- annual servicing of gas heaters or fires - hot water upgrades - kitchen renovations involving a gas hob - rural LPG conversions or tank-related work
If it is an emergency, you may need the first available authorised gasfitter. Even then, ask for clear identification and credentials before work begins.
What professionalism looks like on the day Good service is not just about technical skill. The way a gasfitter behaves on site says a lot about the quality of their business.
Expect them to:
- arrive within the agreed time window, or communicate early if delayed - protect floors and benches where needed - shut off gas safely before working - test thoroughly before leaving - explain how to use the appliance or what warning signs to look for - give you paperwork, invoice details, and any compliance documentation required - clean up after themselves
If they discover a problem, a good gasfitter will explain the issue in plain language and discuss options before proceeding with extra work.
Final checklist before you hire Before you confirm the job, make sure you can tick these off:
- You have at least two written quotes for non-urgent work. - The gasfitter’s licence or authorisation has been checked. - You know whether the job involves LPG, natural gas, or both. - Any likely electrical or building-related work has been identified. - You understand the total price, including GST and any extra fees. - You know what paperwork or compliance records you will receive. - You are comfortable with their communication and professionalism.
A good gasfitter should give you confidence before they even pick up a tool. If they are transparent, properly authorised, well reviewed, and easy to deal with, that is usually a strong sign you are making the right choice.
Taking a little extra time to check credentials and compare quotes can save you money, prevent delays, and help keep your home safe.
