If you've ever quoted a gasfitting or drainlaying job and wondered whether you're charging enough — or received a quote as a homeowner and wondered why it costs more than a standard plumber — this guide is for you.
Gasfitters and drainlayers are among the most tightly regulated trades in New Zealand. That regulation comes with real costs, and understanding those costs is the key to pricing your work fairly and profitably in 2026.
What Gasfitters and Drainlayers Are Charging in 2026
Based on current market data from operators around New Zealand, here's where hourly rates sit in mid-2026:
Gasfitters - Wellington/Auckland metro: $140–$165 + GST per hour - Provincial cities (Hamilton, Tauranga, Christchurch): $125–$148 + GST per hour - Smaller regions and rural: $117–$135 + GST per hour
Drainlayers - Wellington/Auckland metro: $135–$158 + GST per hour - Provincial cities: $118–$140 + GST per hour - Smaller regions and rural: $110–$128 + GST per hour
Call-out fees typically run $65–$95 + GST on top of labour, and urgent or after-hours work adds a 50–100% premium. Most operators also charge for travel time at their standard hourly rate once a job exceeds a minimum distance (commonly 10–15 km).
These rates sit noticeably higher than general plumber rates, which average $95–$130 + GST/hr in comparable regions. The gap isn't arbitrary — it reflects a real difference in compliance overhead, as explained below.
Why These Trades Cost More: The Regulatory Reality
Both gasfitting and drainlaying are controlled under the Plumbers, Gasfitters, and Drainlayers Act 2006, which sits under the Plumbers, Gasfitters and Drainlayers Board (PGDB) — a government-appointed licensing authority. Unlike many trades, it is illegal to carry out gasfitting or drainlaying work in New Zealand without the appropriate licence or registration.
That licensing structure creates ongoing compliance costs that every practitioner must absorb:
1. Registration fees (updated April 2026) The PGDB raised registration fees for the 2026–27 year. Licensed practitioners now pay: - Certifying licence: $445 + GST per year - Journeyman registration: $310 + GST per year - Tradesperson registration: $285 + GST per year
These fees apply per licence category. Someone who holds both a gasfitting licence and a drainlaying licence pays two sets of fees annually.
2. Continuing Professional Development (CPD) PGDB requires licence holders to complete CPD each registration year to maintain their licence. This takes time and often money — courses, travel, and time away from billable work.
3. Inspection and certification requirements Unlike some other trades, gasfitters must complete a Certificate of Compliance (CoC) for each job, and the work may be subject to inspection by a Building Consent Authority (BCA) or the PGDB itself. Preparing and filing CoCs is unpaid administrative work that adds real overhead per job.
4. Insurance exposure Gas is inherently higher risk than water plumbing. Public liability insurers price gasfitting policies accordingly — premiums for $2M cover run $1,800–$3,200/year depending on turnover, compared to $900–$1,600 for general plumbing.
When you add registration fees, CPD, insurance, and compliance admin, a gasfitter or drainlayer is carrying $4,000–$7,000/year in direct compliance costs before they've bought a single fitting.
How to Calculate Your Own Rate
If you're a gasfitter or drainlayer setting your own rate, start with your true cost base — not just your wage expectations.
A common mistake is calculating an hourly rate based on a target annual income, then forgetting to account for:
- Non-billable hours (quoting, admin, travel, compliance)
- PGDB fees and CPD costs
- Vehicle running costs (registration, WoF, fuel, maintenance)
- ACC levies (gasfitters fall into a higher levy category)
- Public liability and professional indemnity insurance
Use our Hourly Rate Calculator to model your rate properly. Most gasfitters find they need to charge at least 30–40% more than their simple "target income ÷ hours worked" calculation to actually break even on costs.
You should also review your overhead rate separately from your labour margin — confusing these two is one of the most common pricing mistakes in small trade businesses.
Sample Rate Calculation
A sole-trader gasfitter in Christchurch might look like this:
| Cost item | Annual |
|---|---|
| Target income (take-home) | $95,000 |
| ACC levy (approx.) | $2,800 |
| PGDB fees (gas + drain) | $890 |
| Vehicle (fuel + maintenance) | $8,500 |
| Public liability insurance | $2,400 |
| CPD + training | $600 |
| Tools and equipment | $2,200 |
| Mobile, admin, software | $1,800 |
| Total cost base | $114,190 |
If that tradie bills 1,000 hours/year (realistic for a sole trader with quoting, travel and compliance time), they need to charge $114.19/hr + GST just to break even at their target income — and that assumes no holidays, no sick days, and no slow periods. Building in a buffer takes the real rate to $125–$135/hr, which aligns with current market rates for the region.
GST: Don't Forget to Add It
All of the rates above are exclusive of GST. If you're GST-registered (which is compulsory once your turnover exceeds $60,000/year), add 15% on top of your rate before presenting it to clients.
On a $140/hr rate, that means invoicing at $161/hr and making clear in your quote that GST is added. Use our GST Calculator to check your invoice totals.
If you're earning close to the $60,000 threshold, it's worth reading up on when and why to register — the timing affects your cash flow significantly in the first year.
Competing on More Than Price
In a stable post-recovery market, the gasfitters and drainlayers growing fastest in 2026 aren't necessarily the cheapest — they're the most responsive and best organised. Same-day quoting, clear written agreements, and reliable job scheduling matter to customers as much as hourly rate.
Apps like Fastcrew are popular with smaller gas and drain operators because they handle scheduling, job notes, and client communication without the complexity (or cost) of larger platforms. For a sole trader or small crew, keeping admin tight means more billable hours and fewer disputes.
Key Takeaways
- Gasfitters charge $117–$165 + GST/hr and drainlayers $110–$158 + GST/hr in 2026, depending on region
- Higher rates than general plumbing are justified by PGDB fees, mandatory CoCs, CPD requirements, and higher insurance costs
- PGDB registration fees increased in April 2026 — factor the updated amounts into your pricing
- Calculate your rate from a full cost base, not just your income target
- Use the Hourly Rate Calculator to run your own numbers
