When a plumber arrives for the first time, you can expect them to assess the problem, ask you some questions, and give you a clear picture of what needs to be done and roughly what it will cost. Most first visits are straightforward, but being prepared helps things go smoothly and ensures you get the best outcome for your home.
Before the Plumber Arrives
A little preparation goes a long way. Before your plumber turns up, it helps to:
- Know where your toby (water toby) is — this is the main water shutoff valve, usually near the boundary or under a small cover in the front yard. Your plumber may need to turn it off quickly.
- Clear the area around the problem — under sinks, behind toilets, or in the laundry. Give them room to work safely.
- Write down the symptoms — when did the problem start, is it getting worse, any unusual smells or sounds? The more detail you can give, the faster they can diagnose the issue.
- Have your tenancy or ownership details ready if you're a landlord or tenant, as this can affect who authorises the work.
What Happens During the Visit
Initial Assessment
Your plumber will start by listening to your description of the problem, then carry out a visual inspection. They'll check the affected fixtures, pipes, or fittings and may use tools like a moisture meter, drain camera, or pressure gauge depending on the issue. Don't be surprised if they need to look in more than one area — plumbing problems often have upstream or downstream causes.
Diagnosis
Once they've had a good look, a good plumber will explain what they've found in plain language. They should tell you:
- What the likely cause is
- Whether it's a straightforward fix or something more involved
- If there are any related issues they've spotted (e.g. signs of water damage, corrosion, or non-compliant work)
If the problem is complex — for example, a suspected leak inside a wall or a blocked drain requiring a camera inspection — they may need to carry out further investigation before giving a firm quote.
The Quote
For most standard jobs, your plumber should be able to give you a written quote or estimate on the day or shortly after. In New Zealand, it's perfectly reasonable to ask for this in writing before any work begins. A quote should include:
- Labour costs (often charged per hour or as a fixed price)
- Materials and parts
- Any call-out or travel fees
- GST (15%)
- An indication of timeframes
As a rough guide, plumber call-out fees and hourly rates vary around the country, so always confirm costs upfront. Prices in Auckland, Wellington, and Christchurch can differ from regional areas.
Restricted Plumbing Work in New Zealand
It's important to understand that most plumbing work in New Zealand is restricted work under the Plumbers, Gasfitters and Drainlayers Board (PGDB). This means it must be carried out by a licensed or certifying plumber. Restricted work includes:
- Installing, altering, or repairing any sanitary plumbing (toilets, sinks, showers, baths)
- Connecting to or modifying the water supply
- Drainlaying and stormwater connections
- Any work on hot water systems
Homeowners can legally do very minor maintenance — like replacing a tap washer or a showerhead — but anything involving pipework, connections, or drainage must be done by a licensed tradesperson. Always ask to see your plumber's licence number and check it on the PGDB website if you're unsure.
For work that affects the structure of your home or involves new drainage connections, a building consent may also be required. Check with your local council, as requirements vary. The MBIE Building Performance website has useful guidance on what triggers consent.
Healthy Homes and Rental Properties
If you're a landlord, some plumbing-related work may be required under the Healthy Homes Standards. This includes ensuring adequate drainage and hot water. Tenancy Services has full details on landlord obligations.
What to Ask Your Plumber
Don't be shy — a good tradesperson welcomes questions. Consider asking:
- Are you licensed with the PGDB?
- Will this work require a building consent?
- Is there a warranty on parts and labour?
- Are there any other issues I should be aware of?
- What can I do to prevent this problem recurring?
When to Call a Professional
Always call a licensed plumber if you have:
- No hot water or a failing hot water cylinder
- Burst or leaking pipes (turn off the toby first)
- Blocked drains that aren't clearing with a plunger
- Low water pressure throughout the house
- Sewage smells inside or outside
- Any plumbing work that goes beyond basic maintenance
For gas-related plumbing (like gas hot water systems), your tradesperson must also hold a gasfitting licence — check the PGDB register. For safety information around plumbing hazards, WorkSafe NZ is a useful resource.
