Do I need a licence to work as a plumber in New Zealand?

Requirements vary by work type and local rules. Contact your local council or MBIE and ask which plumbing tasks require a licensed tradesperson or specific certificates before you start carrying out that work.

How should I set an hourly rate or fixed price?

Decide whether to charge hourly or fixed for common jobs based on how predictable the work is. Include your time, travel, tool wear and materials. Check local listings to see market signals and make sure your price covers your costs.

How to make money as a plumber in New Zealand: practical guide

Updated October 21, 2026

Where paying customers come from

Customers for plumbing work come from a mix of local, repeat and one-off sources. Neighbours and friends often provide the first handful of jobs, because people trust someone they already know. Workplaces and colleagues can lead to small jobs or referrals. Property owners - landlords and property managers - repeatedly need maintenance, and they can become steady customers if you respond reliably.

Online search and local marketplaces are increasingly important. People search for a service near them, compare short listings, and contact the first few that look legitimate. Word of mouth still matters: a single good job can produce several referrals in a suburb. Community noticeboards, social media groups and local classifieds also generate leads. Schools and small businesses sometimes outsource routine maintenance, but those contracts can require formal checks and tenders.

Setting your first price and talking about money

Decide whether you quote hourly, fixed-price for common jobs, or a mix. Fixed quotes are easier for small jobs and customers prefer them for predictability. When you set a first price, cover your time, transport, tool wear, materials, and a margin for unexpected issues. Check local listings and ads to understand what other people charge in your area, but do not copy without accounting for your costs.

When discussing money, be clear and written where possible. Give a short scope - what you will and will not do - and a payment term. Say whether you require a deposit for parts ordered or for scheduled work. If you change scope on site, record the extra work and confirm the additional charge before proceeding.

Choose hourly, fixed or hybrid pricing depending on the job
Include time, travel, tools and materials in your calculation
Write scope and payment terms; confirm changes before extra work

What the first ten customers usually look like

The first ten customers are often a mix of people you already know and quick local leads. Typical early customers include neighbours with a blocked drain or tap leak, a friend or family member asking for help, a workplace facilities manager needing a small repair, and private landlords asking for urgent fixes. You may also win a couple of jobs from online task posts or local Facebook groups.

Expect variety. Many first jobs are straightforward but low-margin; treat them as opportunities to build references, photos and short case notes. Delivering clear invoicing and punctual behaviour matters as much as the technical work in earning repeat business.

Taking money and legal checks in New Zealand

As an independent person in New Zealand you must sort tax, invoicing and any licensing or consent requirements that apply to plumbing work. Check Inland Revenue - ask what registration and filing you need, how to report business income, and whether you should register for GST. For health and safety obligations, check WorkSafe - ask what duties you have as a sole trader on building sites or in customers' homes. For building or plumbing consents and certification, contact your local council or MBIE and ask which parts of plumbing work require approvals or licensed tradespeople.

Keep clear records of every job, issue a simple invoice that shows your name and contact, the work done, the price and payment method, and keep receipts for parts and expenses. If you accept card payments through a platform, check the provider's payout process, fees and reconciliation. Card payments from customers on Websta are paid out to the provider's own bank account through Stripe; the provider sets the prices.

What tends to go wrong in the first months

Common early problems include underquoting time or parts, not having the right spare parts on hand, customers misunderstanding the scope, no-shows or late payments, and underestimating travel time. You may also face admin overload if you do estimates, scheduling and invoicing alone without a simple system.

To reduce risk, set realistic time blocks, carry common spare parts, use a written estimate and acceptance process, request deposits for larger jobs, and have a clear payment method. Make backup plans - a parts supplier you can call, and a way to schedule follow-ups - and protect yourself with basic terms and cancellation rules.

Scope creep and on-site changes without agreement
Late payments and no-shows
Admin overload without simple processes

How a Websta profile fits into this work

A Websta profile is a single page you can send to anyone that looks like a small website: services, prices, photos, a contact form and online booking. It also sits on a marketplace where people nearby search by service and place or post a task for providers to offer on. Use that page as your consistent reference point in text messages, emails and social posts so customers see the same services and prices.

Using the platform makes card acceptance straightforward - card payments from customers are paid out to your own bank account through Stripe. You still set prices and control availability and booking slots. The profile is a tool for being found and for simplifying bookings and payments, but building steady work still relies on delivering good jobs and managing follow-ups.

Send the same profile link to enquiries to avoid confusion
Use photos and short service descriptions to set expectations
Online booking reduces back-and-forth; card payouts go to your bank via Stripe

Next practical steps

Start small: do a few jobs for people you know, practise quoting and invoicing, and collect before-and-after photos and short client permissions to display them. Create a short, clear Websta profile page with the services you want to do, example prices and a simple booking method. While you take jobs, keep one simple spreadsheet or accounting app record for income and expenses.

Contact the authorities listed earlier if you are unsure about tax, consents or health and safety. Ask straightforward questions: what registration or licence do I need to carry out this work, how do I report income and GST, and what safety steps do I need when working in people's homes? Honest answers to those questions will save time and reduce the chance of a problem later.

Do a few jobs for people you know to build references
Make a clear Websta profile and use it as your booking page
Keep simple records and ask Inland Revenue, WorkSafe or your council about legal obligations
