Consumer Rights When Hiring Tradespeople in New Zealand

Consumer Rights When Hiring Tradespeople in New Zealand

Most people assume the law protects them the moment a job goes wrong. It does — but only if you do one specific thing first, and it is the opposite of what most of us instinctively want to do when we are staring at a leaking shower or a crooked fence.

You have to give the original tradesperson the chance to fix it. Skip that step and go straight to someone else, and you lose your right to a remedy entirely. The original trader does not have to pay the new repair bill, and does not have to refund you. That single rule trips up more homeowners than anything else in the Consumer Guarantees Act.

This guide is the hub for everything we have written about hiring trades in New Zealand. Here is how the rights work, what to put in writing before anyone picks up a tool, and what to do when it all goes sideways.

How We Researched This Guide

Rules, rates and policy wording change over time, so we check our figures against the Disputes Tribunal on how to make a claim as we write.

This one is built on the Consumer Guarantees Act 1993 and the Fair Trading Act 1986, both available in full on legislation.govt.nz. We worked through the sections that actually apply to trade work — the four service guarantees in the Consumer Guarantees Act, the substantial character test, and the misleading conduct and unsubstantiated representation provisions in the Fair Trading Act.

Two things surprised us. The first was the Disputes Tribunal limit, which rose from $30,000 to $60,000 on 24 January 2026 — a lot of older material still quotes the old figure. The second was a genuine source disagreement: a Ministry of Justice release mentions a $468 filing fee for the top band, but the Tribunal's own Forms & Fees page, updated 27 July 2026, says $496. We have used $496 throughout, because it is the more current source.

The Quick Summary (60-Second Version)

If you read nothing else, read this.

• Get a written quote, not an estimate. A quote is a fixed price for defined work; an estimate can legitimately be exceeded.
• Check the licence on the official public register — and confirm the class covers your specific job, not just that the person is licensed.
• If work is defective, tell the trader in writing and give them a reasonable chance to fix it. This step is not optional.
• If they refuse, neglect it, or cannot fix it in time, you can get it fixed elsewhere and recover the reasonable cost, or cancel.
• A workmanship warranty sits on top of your Consumer Guarantees Act rights. It cannot replace them.
• The Disputes Tribunal hears claims up to $60,000, with filing fees from $62 to $496.

What the Consumer Guarantees Act Actually Promises You

When you hire a tradesperson for household work, you are buying a service, and the Consumer Guarantees Act attaches four guarantees to it. The work must be done with reasonable care and skill. It must be fit for any particular purpose you made known. It must be completed within a reasonable time if no timeframe was set. And it must be charged at a reasonable price if no price was agreed beforehand.

That first guarantee is the workhorse. Section 28 sets the standard as what a competent person with average skills and experience would do, applied with technical know-how. Note what it does not require: intent. A job done badly is a breach even if the tradesperson tried hard and meant well. Inexperience is not a defence.

When a failure is serious enough to cancel

Section 36 defines a failure of substantial character. It covers services a reasonable consumer would not have bought if they had known what was coming, work that is substantially unfit for its normal purpose and cannot easily be fixed in reasonable time, work that fails a purpose you specifically made known, and — the one that matters most in trades — work that is unsafe.

Water getting behind a shower lining is the classic example. It is unsafe, it is unfit for purpose, and it cannot be easily remedied. That is a substantial failure, and it opens up cancellation and a refund.

The remedy path, in order

Quotes, Contracts and the Fair Trading Act

The Consumer Guarantees Act price guarantee only applies where a price was not set beforehand. Once you agree a fixed price, that guarantee is not your protection — the contract is. Which is why the quote-versus-estimate distinction matters so much.

A quote is a fixed price for defined work. An estimate is an approximation and can legitimately be exceeded. Ask for a quote, in writing, every time. It is the single best protection available in a trade job.

What a good written quote contains

The GST trap catches people constantly. One quote may be GST-exclusive and another GST-inclusive, which means a 15 per cent gap that is pure accounting rather than a real price difference. Confirm the basis on every quote before you compare them.

Variations are where budgets break

Extra work found after starting — rot behind a wall, non-compliant wiring, an unseen leak — is the most common way a job costs more than quoted. Agree a written variation process in advance, requiring your sign-off before extra work proceeds. That is your protection.

When it is a Fair Trading Act problem instead

Checking Credentials and Taking It to the Tribunal

New Zealand keeps separate public registers for each licensed trade, and checking one is free and takes minutes. It is the most reliable way to avoid hiring someone who cannot legally do the work.

The three questions that cover any trade

Ask for the licence or registration number. Check it on the relevant public register. Then confirm the class or endorsement covers the specific work being done — because a licensed practitioner in the wrong class is effectively unlicensed for that job. The Licensed Building Practitioner scheme covers individuals, not companies, so check the person doing or supervising the work.

For building work, electrical work, and plumbing, gasfitting and drainlaying, there is a register and a disciplinary process behind it. For trades with no licensing regime, the substitutes are a qualification-requiring professional body membership, a company registration number, evidence of insurance, references from recent local jobs, and a written contract.

The Disputes Tribunal

If the dispute cannot be settled, the Tribunal is where it goes. It can hear claims up to $60,000, and you usually represent yourself — a lawyer cannot make your case for you, though you can get legal advice. Filing fees run from $62 for claims under $2,000 up to $496 for the $30,001 to $60,000 band, and they are non-refundable, though the Referee may order the other side to cover them if you succeed.

Questions You Might Have

Can the tradesperson charge more than the quote?

Not for the work covered by the quote. A fixed quote must be honoured unless you agree to changes. Extra work discovered mid-job is the usual reason a bill grows, which is why a written variation process agreed in advance matters so much. If they simply demand more for the same scope, that is a dispute you can take further.

What if I already paid someone else to fix it?

Then you have likely lost your remedy against the original trader. The Act requires you to give the supplier the chance to fix a minor problem first. If you arrange a repair elsewhere without doing that, the original trader is not liable for the bill and does not have to refund or replace. It is harsh, but it is the rule.

Do I have to pay for work I am unhappy with?

It depends on whether the work has value. If the failure is substantial, you can cancel and refuse to pay, or pay less. If the service has been provided and still has some value, you may only be entitled to a partial refund, and may still owe part of the bill. Get advice before simply withholding payment.

Can a one-year workmanship warranty limit my rights?

No. A trader cannot contract out of the Consumer Guarantees Act for consumer work. A workmanship warranty is a contractual promise that sits on top of your statutory rights, not instead of them. Where a failure is substantial, the statutory position applies regardless of what the warranty says.

What if the tradesperson claims a qualification they do not have?

That is a Fair Trading Act issue rather than a workmanship one. Section 13 prohibits false representations about qualifications or skill, and section 12A prohibits claims made without reasonable grounds at the time. Report it to the Commerce Commission, which is the only body that can take proceedings under the unsubstantiated representation provision.

What Matters Most

The law here is genuinely strong. The Consumer Guarantees Act applies regardless of what the contract says, and no trader can contract out of it. But it only works if you follow the sequence: quote in writing, credentials checked on the register, scope and variations agreed, and — if something goes wrong — a written request to the original trader to put it right.

That last step is the one people skip, usually because they just want the problem gone. It is also the step that decides whether you have a remedy at all. Give them the chance, in writing, and keep the evidence.

Everything else is preparation. The lowest quote is rarely the best value, because the cheapest quote is usually the one with the narrowest scope. Compare price against scope against credentials against timeframe, and photograph the area before work starts. That is free, takes a minute, and removes a whole class of arguments.
