Paying a deposit to a tradesperson is common in New Zealand, but it should always make sense for the type of job, the materials involved, and the way the payment is structured. A sensible deposit can help secure a start date and cover upfront costs, but an excessive one can leave homeowners exposed if the job changes or the contractor does not perform.
When is a deposit reasonable?
A deposit is usually reasonable when the tradesperson needs to buy materials, book labour, or reserve time specifically for your job. This is especially common for custom work, smaller specialist businesses, and projects where materials are ordered to measure.
Situations where a deposit is more common
• Custom joinery, kitchens, wardrobes, and cabinetry
• Made-to-order windows, doors, or aluminium glazing
• Roofing jobs where sheet products or flashings must be ordered
• Bathroom renovations with specialist fixtures already selected
• Landscaping or fencing jobs with significant material purchases
• Any project where the tradesperson is holding a slot in a busy period, such as summer or pre-winter maintenance
For straightforward labour-only work, a deposit is less common. For example, a minor repair, maintenance call-out, or a simple installation may be billed on completion or by invoice after the job is finished.
How much deposit is normal in NZ?
There is no single legal standard percentage for all trades in New Zealand, so what is reasonable depends on the job. For smaller and lower-risk jobs, a deposit is often modest. For larger projects with expensive materials, it may be higher, but it should still be tied to actual upfront costs rather than a large chunk of the total price.
Indicative deposit ranges
• Small repair or maintenance job: 0% to 20%
• Standard residential job with some materials: 10% to 30%
• Custom-made products or specialist fabrication: 20% to 50%
• Large renovation or staged project: often 10% to 20% upfront, then progress payments
As a general rule, be cautious if a tradesperson asks for a very large deposit before any work begins, particularly if the job is simple or low cost. A deposit should not be mistaken for the full cost of materials unless those materials are being ordered specifically for your project and cannot easily be returned.
How to protect yourself before paying
A deposit is safest when the scope, price, and payment stages are clear in writing. A proper quote or contract should spell out what you are paying for, when each payment is due, and what happens if the job changes.
Ask for these details first
• A written quote, not just a text message estimate
• A clear description of the work and materials included
• The deposit amount and what it covers
• The expected start date and completion timeframe
• Any conditions for refunds if the job is cancelled or delayed
• How variations will be priced and approved
• The tradesperson’s business name, invoice details, and GST status if applicable
It also helps to check whether the tradesperson is suitable for the type of work. For electrical, gasfitting, and other regulated work, make sure the person is appropriately licensed and able to provide the correct paperwork on completion.
Practical payment protection tips
• Pay by internet banking or another traceable method, not cash
• Keep copies of quotes, invoices, and email or text approvals
• Never pay a large deposit without a signed agreement for larger jobs
• If materials are being ordered, ask for proof of the order
• Be cautious if you are asked to pay the full amount before work starts
• Check that the payment name matches the business trading name or invoice details
If a contractor becomes unresponsive after taking a deposit, your documentation becomes important. Clear records make it easier to raise a dispute, request a refund, or seek help through the Disputes Tribunal or another appropriate pathway.
Progress payment schedules: what fair looks like
For larger projects, progress payments are often better than one large upfront deposit. They spread risk and keep both sides accountable. The payment stages should track real milestones, not just dates on a calendar.
Common progress payment structures
• Deposit on acceptance of quote
• Payment when materials are ordered or delivered
• Payment after demolition or preparation is completed
• Payment after major installation stages
• Final payment only after practical completion and any agreed defects are fixed
A fair schedule depends on the size and complexity of the job. For example, a bathroom renovation might have a deposit to cover fixtures, a second payment after rough-in, and a final balance after completion. A kitchen project may include staged payments linked to cabinetry order, delivery, installation, and handover.
What to avoid
• Paying most of the cost before any work has started
• Agreeing to vague milestones such as “midway through the job” without detail
• Paying the final amount before checking the completed work
• Allowing progress payments that do not match actual work done or materials supplied
A sensible progress schedule should feel balanced. The homeowner should not carry all the risk, and the tradesperson should not be forced to fund the entire project upfront.
Red flags that the deposit is too high
A large deposit is not automatically a scam, but it deserves more scrutiny if several warning signs are present. Trust your instincts and slow down if anything feels rushed or unclear.
Watch for these warning signs
• The tradesperson pressures you to pay immediately
• The quote is much lower than others, but the deposit is unusually high
• You are asked to pay in cash or into a personal account with no clear explanation
• There is no written scope of work or payment schedule
• The contractor avoids discussing start dates, product lead times, or refunds
• The business has poor communication before the job even starts
For big-ticket jobs, it is sensible to compare at least two or three quotes. The cheapest quote is not always the best if it relies on a large deposit or leaves important details out.
What to do if the job changes or goes wrong
If the scope changes after you have paid a deposit, get the variation confirmed in writing before more work proceeds. If materials become unavailable, ask for an updated timeline and a revised payment schedule.
If the tradesperson fails to start the job, walks away, or does not deliver what was agreed, gather your records and contact them in writing first. Set out what was promised, what has happened, and what you want next, whether that is completion, a refund, or a partial refund.
If the dispute cannot be resolved, the Disputes Tribunal may be an option for many consumer trades disputes in New Zealand, depending on the amount involved and the circumstances. For urgent issues, especially where safety or compliance is a concern, seek advice promptly.
A good deposit arrangement is meant to support the job, not expose you to unnecessary risk. If the deposit amount is reasonable, the paperwork is clear, and payments are tied to progress, it can work well for both sides.
Bottom line for homeowners
A deposit is often fair in New Zealand when there are real upfront costs, custom materials, or a booked project slot. For many jobs, 10% to 30% is a common range, while larger or specialist projects may justify more, but only with clear terms.
Before paying, make sure the quote is written, the payment stages are defined, and you can see what the deposit covers. For larger jobs, progress payments usually offer better protection than a single large upfront payment.
