Top 10 Questions to Ask Before Hiring Any Professional in NZ

Hiring a professional — whether a plumber, builder, electrician, accountant, or cleaner — is a significant decision. Ask the wrong questions (or none at all) and you risk delays, cost overruns, substandard work, or worse. Ask the right ones, and you’ll hire with confidence every time. Here are the ten questions every New Zealander should ask before signing anything.

Question 1: Are you licensed or registered for this type of work?

In New Zealand, many trades and professions require a licence or registration by law. Electricians must be registered with the EWRB, builders carrying out restricted building work must hold an LBP licence, and plumbers and gasfitters must be registered with the PGDB. Ask directly, then verify it yourself on the relevant government register. A legitimate professional will welcome the question.

Question 2: Are you insured, and can I see your certificate?

Public liability insurance protects you if the professional accidentally damages your property or injures someone during the job. For design and consulting work, professional indemnity insurance is also important. Always ask to see the current certificate — not just a verbal yes. Insurance policies expire, so confirm it’s current.

Question 3: Can you provide a written quote?

Any reputable professional will provide a written quote without hesitation. A proper quote should include a detailed scope of work, the specific materials to be used, an itemised cost breakdown, the expected start and completion dates, and any warranty on workmanship. If someone is reluctant to put it in writing, walk away.

Question 4: How long have you been operating, and do you have local references?

Experience matters, but relevant local experience matters more. A builder who has worked in Auckland for ten years understands local council requirements, local material suppliers, and common NZ construction challenges. Ask for two or three references from jobs of a similar scope and actually call them. Most people don’t — which is exactly why those who do stand out.

Question 5: Who will actually be doing the work?

This is one of the most overlooked questions. The person who quotes the job isn’t always the person who shows up to do it. On larger jobs, the principal contractor may subcontract work to others. Ask who specifically will be on site, whether they are also licensed where required, and whether the person you’re hiring will be supervising throughout.

Question 6: What is the payment schedule?

Never pay the full amount upfront. A professional payment structure for most jobs in NZ is a deposit on acceptance (typically 10–20%), progress payments tied to milestones, and a final payment upon satisfactory completion. Be especially cautious of anyone who demands more than 30–40% upfront before work has started.

Question 7: How do you handle variations or unexpected costs?

On any renovation or building job, surprises happen. The key question is: how will they be handled? Ask that all variations be agreed in writing before extra work begins, and get clarity on how variation pricing is calculated. A professional contractor will have a clear process for this. If they shrug and say “we’ll figure it out”, that’s a red flag.

Question 8: What is your workmanship warranty?

Under the Consumer Guarantees Act, work must be completed with reasonable care and skill. But many professionals also offer their own workmanship warranty on top of this — typically 12 months. Ask what their warranty covers, how long it lasts, and how you should contact them if an issue arises after the job is done. Get it in writing as part of your contract.

Question 9: Are you GST registered?

In New Zealand, any business earning over $60,000 per year is required to be GST registered. Asking for a GST number is a quick way to verify you’re dealing with a legitimate, established operator. You can verify GST registration at ird.govt.nz. An unregistered tradesperson doing substantial work is either very new to the industry or working under the table — neither is ideal.

Question 10: How will you communicate with me throughout the job?

Poor communication is the number one complaint in the NZ trades industry. Before work begins, agree on how progress will be communicated, who to contact if you have questions, and how quickly you can expect responses. This sets expectations on both sides and reduces friction during the job. A professional who dismisses this question is telling you something important.

Frequently Asked Questions

What is the most important question to ask a tradie in NZ?

Verification of licensing and insurance are the two most critical checks. Without both, you have no protection if something goes wrong.

Can I ask for references before hiring a professional?

Absolutely — and you should. Any reputable professional will readily provide references from recent, similar-scope jobs. If they hesitate or can’t provide any, that is a significant warning sign.

What should be in a quote from a NZ professional?

A proper written quote should include the scope of work, materials, itemised pricing, start and completion dates, a payment schedule, and the workmanship warranty.
