Questions to Ask Before Hiring a Tradesperson in NZ

Questions to Ask Before Hiring a Tradesperson in NZ

Whether you're renovating a bathroom, fixing a leaky roof, or building a deck, hiring the right tradesperson can make or break your project. In New Zealand, the building and trades industry is largely self-regulated, so asking the right questions before you commit is essential to protect your home, your budget, and your timeline.

This guide walks you through the key questions to ask any tradesperson before you hire them. It covers licensing, insurance, quotes, contracts, and more — helping you avoid costly mistakes and unnecessary stress.

Why asking questions matters

New Zealand has specific laws and industry standards that tradespeople must follow. The Building Act 2004, the Consumer Guarantees Act, and the Fair Trading Act all apply to trades services. However, enforcement often relies on consumers being informed.

Asking the right questions helps you:

• Verify the tradesperson is legally allowed to do the work
• Understand what you're paying for and when
• Protect yourself if something goes wrong
• Avoid disputes over scope, quality, or delays

Step 1: Check licensing and qualifications

In New Zealand, certain trades require a licence. For example, plumbers, gasfitters, drainlayers, and electricians must be licensed by the relevant authority. Builders can be either licensed (LBP) or unlicensed, but many homeowners prefer LBPs for peace of mind.

Key questions to ask:

• Are you a Licensed Building Practitioner (LBP)?
• What is your licence number and class?
• Can you provide proof of your qualifications?
• Do you hold any relevant trade certifications (e.g., Master Plumber, Master Electrician)?

You can verify LBP status on the LBP register. For electricians, check the Electrical Workers Registration Board. For plumbers and gasfitters, use the Plumbers, Gasfitters and Drainlayers Board.

Step 2: Confirm insurance coverage

Insurance is non-negotiable. A tradesperson should have at least public liability insurance and, ideally, professional indemnity insurance. If they damage your property or someone gets injured, you don't want to be left paying the bill.

Key questions to ask:

• Do you have current public liability insurance?
• What is your coverage amount? (Typically $1 million to $2 million)
• Can you provide a certificate of insurance?
• Do you have workers' compensation cover for your employees?

If they're a sole trader, ask about their personal accident insurance. If they're uninsured, consider whether the risk is worth it.

Step 3: Get a detailed written quote

Verbal quotes are risky. Always ask for a written quote that breaks down costs, materials, and labour. This protects both parties and makes it easier to compare quotes from different tradespeople.

Key questions to ask:

• Can you provide a detailed written quote (not just a ballpark estimate)?
• What is included in the price — materials, labour, disposal, consent fees?
• What is NOT included that might come up?
• Is the quote fixed price or time-and-materials?
• How long is the quote valid for?

Be wary of quotes that are significantly lower than others — they may cut corners or add unexpected charges later. A mid-range quote with clear details is often the safest choice.

Step 4: Understand payment terms

Payment terms vary widely in New Zealand. Some tradespeople ask for a deposit, others bill on completion. Knowing the payment schedule upfront avoids surprises.

Key questions to ask:

• What are your payment terms? (e.g., deposit, progress payments, final payment)
• How much deposit do you require? (A deposit over 10-20% is unusual for small jobs)
• When is the final payment due?
• Do you accept credit cards, bank transfer, or cash?
• Are there late payment fees?

Never pay the full amount upfront. A common practice is 10-20% deposit, with progress payments for larger jobs, and the balance on completion and satisfaction.

Step 5: Ask about warranties and guarantees

Under the Consumer Guarantees Act, services must be carried out with reasonable care and skill, and materials must be fit for purpose. However, it's wise to ask about specific warranties.

Key questions to ask:

• Do you offer a warranty on your work? If so, for how long?
• Are there any warranties on materials or products used?
• What happens if there's a problem after the job is done?
• Will you cover the cost of fixing defects?

Typical warranties range from 1 to 10 years depending on the trade and the work. For structural work, an LBP must provide a 10-year implied warranty under the Building Act.

Step 6: Check references and reviews

Online reviews are helpful, but speaking directly to past clients gives you a clearer picture. Ask for references from recent jobs similar to yours.

Key questions to ask:

• Can you provide at least two recent references?
• Have you done similar work before? Can I see photos?
• How do you handle customer complaints or disputes?
• Are you a member of any trade association (e.g., Master Builders, NZ Plumbing Contractors)?

Trade associations often have dispute resolution processes and codes of conduct, which can add an extra layer of protection.

Step 7: Clarify timelines and project management

Delays happen, but clear communication about timelines helps manage expectations. Ask how the tradesperson handles scheduling, especially if multiple trades are involved.

Key questions to ask:

• What is your estimated start date and completion date?
• How do you handle weather delays or supply issues?
• Will you be on-site every day, or will subcontractors be used?
• Who is the main point of contact during the project?
• How will you communicate progress?

For larger projects, ask for a written schedule or timeline. If subcontractors are involved, ask about their qualifications and insurance too.

Step 8: Discuss consent and compliance

Many home renovations in New Zealand require building consent from your local council. Some smaller jobs may be exempt, but it's your responsibility to check. A good tradesperson will guide you through this.

Key questions to ask:

• Does this project require building consent?
• Who will apply for the consent — you or me?
• Are you familiar with the local council's requirements?
• Will you handle inspections and sign-offs?
• What happens if the work doesn't pass inspection?

If consent is required and not obtained, you could face fines, legal issues, or problems selling your home later. Always clarify this early.

Step 9: Understand the contract

A written contract protects both parties. For smaller jobs, a simple agreement may suffice. For larger projects, a standard form contract (like the NZS 3910 or a trade association template) is recommended.

Key questions to ask:

• Do you use a written contract for all jobs?
• Can I review the contract before signing?
• What are the terms for variations or changes to the scope?
• Is there a dispute resolution process outlined?
• What happens if either party cancels?

Read the contract carefully. If anything is unclear, ask for clarification or seek legal advice before signing.

Step 10: Trust your instincts

Finally, pay attention to how the tradesperson communicates. Are they responsive, professional, and willing to answer your questions? Do they arrive on time for meetings? A good tradesperson will be transparent and patient.

If something feels off — whether it's pressure to pay upfront, vague answers, or refusal to provide references — walk away. There are plenty of reputable tradespeople in New Zealand.
