What counts as a gasfitting emergency in NZ?
A gasfitting emergency is any situation where gas may be escaping, igniting incorrectly, or making people unsafe. In New Zealand, gasfitting is restricted work, so urgent repairs should be handled by a suitably licensed gasfitter under the Plumbers, Gasfitters and Drainlayers Board (PGDB).
Treat the situation as urgent if you notice any of these:
- a strong smell of gas indoors or around a gas meter, cylinder, BBQ, heater, cooktop or water heater - hissing sounds from gas pipes, fittings or regulators - a gas appliance that won’t light properly, keeps going out, or has an orange/yellow flame instead of a steady blue flame - soot marks, scorch marks or unusual heat around an appliance or flue - headaches, dizziness, nausea or feeling unwell when gas appliances are operating - damage to gas piping after a quake, renovation, leak, impact or flooding - a suspected carbon monoxide issue from a flued appliance
Not every fault needs an emergency response. For example, a pilot light going out, a cooker ignition fault, or a heater needing servicing is often urgent but not necessarily an immediate danger if the gas is isolated and there is no smell of gas. Still, if you are unsure, err on the side of caution and call for help.
What to do immediately
If you suspect a gas leak or unsafe appliance, safety comes first. Do not try to fix the issue yourself.
Follow these steps:
1. **Turn off the gas if it is safe to do so.** - For natural gas, turn off the appliance isolating valve if you can reach it safely. - For LPG cylinders, close the cylinder valve. - If you do not know how, do not waste time experimenting.
2. **Do not use anything that could ignite gas.** - do not smoke - do not light matches or candles - do not use switches, plugs or appliances if there is a strong gas smell indoors - avoid mobile phones inside the affected area if the smell is strong; move outside first if practical
3. **Ventilate if it is safe.** - open doors and windows on your way out if you can do so without switching anything on or off - if gas is heavily leaking, get everyone out first
4. **Evacuate people and pets.** - leave the property if the smell is strong, you hear hissing, or anyone feels unwell - keep children away from the area
5. **Call for urgent help from outside.** - contact a licensed gasfitter with an after-hours service if it is a repair issue - if the leak is significant, you cannot isolate it, or there is immediate danger, call emergency services - in a large leak or if you suspect an explosion risk, treat it as a life-safety emergency
6. **Do not re-enter until told it is safe.** - wait for the gasfitter or emergency responders to clear the property
If anyone has symptoms such as dizziness, headache, confusion or nausea, get them into fresh air right away and seek medical advice. Carbon monoxide can be especially dangerous because it is invisible and odourless.
When to call a gasfitter vs emergency services
A gasfitter is the right first call for many gas problems, but some situations need emergency services straight away.
| Situation | What to do | |---|---| | Strong smell of gas but everyone is safe and you can leave the property | Evacuate, avoid ignition sources, then call an urgent gasfitter | | Small appliance fault with no gas smell and no sign of danger | Book an urgent repair or service call | | Hissing gas leak, damaged pipe, or gas cannot be isolated | Leave immediately and call emergency services if there is any immediate risk, then contact a gasfitter | | Suspected carbon monoxide exposure | Get fresh air, call emergency help if anyone is unwell, and arrange urgent gasfitter inspection before using the appliance again | | Gas issue after an earthquake, flood, renovation or impact | Shut off gas if safe, evacuate if needed, then arrange urgent inspection |
A good rule: if the problem could lead to fire, explosion or poisoning, treat it as an emergency. If it is mainly a fault that stops an appliance working safely, it is usually urgent rather than life-threatening.
Typical after-hours callout costs in NZ
Emergency gasfitting is usually more expensive than daytime work because you are paying for priority attendance, travel, and after-hours labour. Prices vary by region, whether you are in a city or rural area, the time of day, and how quickly a gasfitter can get to you.
Typical pricing you may see in New Zealand:
- **After-hours callout fee:** about **$120 to $250+** - **Urgent first hour labour:** about **$150 to $300+** - **Weekend/public holiday surcharge:** often higher than normal rates - **Extra travel charges:** more common in rural or out-of-town jobs - **Parts and materials:** charged separately, especially for valves, regulators, flexi connections, seals or replacement components
For a straightforward urgent visit in a main centre, the total may land around **$250 to $500+**. If the job is more complex, needs parts, or involves multiple appliances, the bill can be much higher. A full fault diagnosis, compliance work, or replacement of a failed regulator or appliance can push the cost into the **$500 to $1,500+** range, depending on what is required.
Things that affect the price:
- time of day and day of week - whether the gasfitter has to travel across town or rural distances - whether the issue is a simple isolation and relight, or a full leak investigation - the age and accessibility of the system - whether parts are on hand or need to be sourced later - whether another trade is needed for related work, such as an electrician for an ignition issue
Ask about the callout fee before booking if you can. A reputable tradesperson should be clear about their after-hours rate, minimum charge and whether GST is included.
How to find urgent help fast
When time matters, speed and verification are both important. You want someone available quickly, but you also want a person who is properly licensed for gasfitting work in NZ.
Use this checklist:
- look for a **current PGDB licence** for gasfitting work - ask for their **full legal business name** and licence details - confirm they provide **after-hours emergency callouts** - ask how quickly they can attend and whether they cover your suburb or rural area - request an **estimate of the callout fee** and the hourly rate before they leave for your job - ask whether they carry common gas parts on the van - get written confirmation by text or email if possible
It is worth comparing two or three providers if the situation is safe to wait a short time. In a non-life-threatening urgent job, you may find a better balance of speed and cost by calling around.
If you are in a regional area, your choice may be more limited and travel fees may be higher. In peak winter months, when gas heaters and hot water systems are under heavier use, after-hours availability can also tighten up, especially in colder parts of the South Island and inland regions.
What a gasfitter may do on an emergency visit
An urgent callout usually starts with making the site safe, then diagnosing the problem. Depending on the issue, the gasfitter may:
- isolate the gas supply to the faulty appliance or whole property - test for leaks using appropriate equipment - inspect regulators, valves, flexible connectors and appliance pipework - relight or recommission a safe appliance - repair or replace failed fittings or components - advise if the appliance must remain out of service - issue documentation if required for the work completed
If the fault is with the appliance itself, it may need manufacturer-approved parts or a follow-up service. If the issue affects building penetrations, flues or structural components, additional work or approvals may be required.
Credentials and compliance you should check
Gasfitting work in New Zealand is restricted and should be done by a suitably licensed person. Before you agree to urgent work, check:
- **PGDB licence** for gasfitting - whether they are licensed for the specific type of work required - whether they are insured - whether they will provide a **certificate of compliance** or other documentation where required
If the gas emergency is tied to a renovation, appliance replacement or alteration of pipework, there may also be broader compliance issues. Some related building work can require council consent, and electrical work must be done by a registered electrician where it falls under electrical regulations. If the gasfitter says another trade or consent is needed, take that seriously.
Do not let urgency override credentials. A quick, cheap repair from an unlicensed person can create a bigger safety risk and more cost later.
How to reduce the chance of an emergency
Most gas emergencies are preventable with routine care. Good habits include:
- booking regular servicing for gas heaters, boilers, cooktops and hot water systems - keeping vents, flues and air intakes clear - replacing old flexible hoses and worn seals before they fail - using a licensed gasfitter for any modification or relocation - checking appliances after earthquakes, renovations or flooding - installing and maintaining carbon monoxide alarms where appropriate - shutting off and having appliances inspected if they have been unused for a long time
For LPG users, check cylinder connections, regulators and outdoor hoses regularly, especially after heavy rain, storms or summer BBQ season use. For natural gas households, be alert after roadworks, property work or anything that may have disturbed underground services or pipework.
Bottom line
If you smell gas, suspect a leak, or notice signs of combustion problems, treat it as an emergency first and a repair second. Get people out if needed, avoid ignition sources, and call a licensed gasfitter quickly.
Emergency gasfitting in NZ commonly costs more than a standard service call, with after-hours callouts often starting around **$120 to $250+** and total urgent visits often landing between **$250 and $500+** or more depending on the fault. Always confirm pricing, check the gasfitter’s licence, and get written quotes where the situation allows.
