Why insurance matters when hiring a joiner A joiner often works inside your home, around valuable finishes, appliances and fixed fittings, and may be responsible for custom-built cabinetry, doors, stairs, benchtops, wardrobes or timber detailing. Even careful tradespeople can make mistakes or cause accidental damage. If something goes wrong and the joiner is uninsured, the cost and hassle can quickly fall back on you.
For NZ homeowners, insurance is not just about whether the job gets completed — it’s about protecting your house, your money and your ability to sort out problems without a fight. It is especially important if the work is happening in an occupied home, on a tight renovation schedule, or in a high-value kitchen or bathroom where one accident can be expensive.
What insurance should a joiner carry? There is no single law that says every joiner must carry the same insurance in all situations. But a professional joiner working in New Zealand should normally have cover that matches the risks of the job. The main policies to ask about are:
| Type of insurance | What it covers | Why it matters to you | |---|---|---| | Public liability insurance | Injury to third parties and accidental damage to other people’s property | Helps pay if the joiner damages your home, belongings or injures someone on site | | Contract works insurance | Loss or damage to the work being done, materials on site, and sometimes temporary structures | Useful if a storm, fire, theft or accidental damage affects an in-progress job | | Professional indemnity insurance | Design errors, measurement mistakes, or faulty advice where the joiner has provided design/specification services | Important if the joiner is designing cabinetry, stairs or bespoke solutions and a mistake causes cost or rework | | Tool and equipment cover | Theft or damage to the joiner’s tools and gear | Helps keep the job moving if tools are stolen from a ute or site | | Vehicle insurance | Damage or loss involving work vehicles | Not directly for you, but a sign of a properly insured business | | Employers’ liability / workers’ cover arrangements | Injury to employees or labour-only helpers, depending on business structure and insurance arrangements | Reduces the risk of a dispute if someone gets hurt on site |
Public liability is the big one most homeowners should ask about first. It is the policy that helps if a joiner accidentally damages your flooring, cracks a benchtop, drills through a hidden pipe, or knocks a heavy panel into a wall.
How insurance protects the homeowner Good cover can protect you in a few practical ways:
- **Damage to your property**: For example, if an installed cabinet is dropped and dents a polished concrete floor, or a saw cuts through a wall cavity and damages pipework. - **Injury claims**: If a visitor, neighbour, or even a member of your household is injured because of the worksite, public liability can help manage the claim. - **Costly rework**: If a measurement error or design issue means cabinetry must be remade, professional indemnity may come into play. - **Project delays**: Contract works or tool cover can reduce the chance that theft, fire or accidental damage stalls the job for weeks. - **Dispute reduction**: Knowing the joiner has insurance often makes it easier to resolve problems quickly and professionally.
Insurance does not make a bad tradie good, and it does not replace proper workmanship, a clear quote, or a written contract. But it can be the difference between a manageable hiccup and a very expensive problem.
What insurance does not usually cover Homeowners should not assume every loss is automatically covered. Typical exclusions may include:
- wear and tear or normal deterioration - poor workmanship that the policy specifically excludes - disputes about price, timing or scope - pre-existing damage - work carried out outside the policy terms - damage caused by the homeowner’s own instructions if the joiner reasonably warned against them
That is why it is worth checking both the insurance and the quote carefully. A policy may exist, but it may not cover the type of job you are hiring for, or it may have a very high excess.
Is a joiner legally required to be insured in New Zealand? Not always. Unlike some regulated trades, there is no blanket national law requiring every joiner to hold public liability insurance. However, many reputable joiners do carry it because it is standard business practice and often expected by clients, builders, project managers and commercial sites.
It is also worth remembering that joinery work can overlap with other regulated or consent-related work:
- **Electrical work** must be done by, or under the supervision of, appropriately authorised electrical workers under the Electricity (Safety) Regulations and the EWRB framework. - **Plumbing, gasfitting and drainlaying** are restricted trades under the PGDB regime. - **Building work** may require a building consent from your local council, depending on the scope of the job.
If your joiner is coordinating with these trades, make sure each contractor has the right qualifications and insurance for their own part of the project.
Questions to ask before you hire Before you sign anything, ask for the joiner’s insurance details in writing. Keep it simple and specific.
Useful questions include:
- Do you carry **public liability insurance**? - What is the **policy limit**? Many businesses carry $1 million, $2 million or $5 million cover, but the right amount depends on the job. - Does the policy cover work **inside occupied homes**? - Do you have **contract works** cover for the materials and job while the project is underway? - If you are designing custom joinery, do you have **professional indemnity** cover? - Are your **subcontractors** covered too, or do you require them to show their own insurance? - Can you provide a **certificate of currency** or proof of insurance? - What is the **excess** on the policy? - Are there any **exclusions** I should know about for this kind of work?
A good tradesperson should answer without hesitation. If they are vague, defensive, or refuse to provide proof, treat that as a warning sign.
How to confirm the cover is real Do not rely on a casual verbal assurance. Ask for documentation.
What to request Ask for:
- a current **certificate of currency** - the **policy type** and insurer name - the **policy number** - the **expiry date** - the **name of the insured entity** — make sure it matches the business you are hiring
What to check Look for these details:
- the policy is current on the date the work will happen - the insured business name matches the invoice, quote or contract - the cover type suits the work you are paying for - the limit is sensible for the value of the job and your property - the policy does not exclude residential joinery or onsite installation
If the project is large — for example a full kitchen, multiple built-in wardrobes, a custom staircase, or a renovation where joinery is part of a bigger build — it is reasonable to ask for a higher level of cover than you would for a small repair.
Insurance should sit alongside other checks Insurance is important, but it should never be your only filter. In New Zealand, a careful homeowner should also check:
- **References and recent local work**: Ask to see similar jobs completed in NZ homes. - **Written quotes**: Compare at least two or three written quotes so you understand pricing, inclusions and exclusions. - **Scope of work**: Make sure the quote states materials, finishes, installation, demolition, removal of waste, and any site preparation. - **Payment terms**: Avoid paying a large deposit unless it is clearly explained and reasonable. - **Warranty or defects period**: Ask what happens if drawers misalign or doors need adjustment after installation. - **Health and safety**: A professional joiner should manage site safety, especially where tools, dust and other trades are involved.
If the joiner is part of a wider renovation, ask the main builder or project manager how responsibility is allocated between trades. Insurance works best when every party understands who is doing what.
Signs the joiner may not be properly covered Watch for these red flags:
- they say insurance is “not necessary” or “only for big companies” - they cannot produce a certificate of currency - the quote is unusually cheap but vague on what is included - they want cash only and do not provide an invoice - they suggest working without a written agreement - their business name on the quote does not match the insurance documents - they do not mention subcontractors, even though part of the work will be outsourced
A low price can be tempting, especially when renovation budgets are tight, but uninsured work can cost far more if something goes wrong.
What to do if damage happens If you discover damage during or after the joinery job, act quickly:
1. **Document it** with photos and notes. 2. **Tell the joiner immediately** in writing. 3. **Stop further work** if continuing would make the damage worse. 4. **Ask for their insurer details** and claim process. 5. **Keep all quotes, invoices and messages**. 6. **Notify your own house insurer** if the damage affects your home contents or building cover.
The faster the issue is reported, the easier it is to establish what happened and whether the joiner’s insurance should respond.
The bottom line for NZ homeowners Yes — your joiner should be insured, and you should ask to see proof before they start. Public liability is the minimum cover most homeowners should expect, and for larger or more complex jobs, contract works and professional indemnity are also worth asking about.
Insurance will not guarantee perfect workmanship, but it does protect you from some of the most expensive risks in a renovation. Combine it with a written quote, clear scope, recent references and sensible payment terms, and you will be in a much stronger position to hire with confidence.
