Getting quotes from tradespeople is one of the most important steps in any home improvement project — and one of the easiest to get wrong. A low number on a page can look appealing, but without knowing what's included (and what isn't), you could end up paying far more than you bargained for. This guide walks you through the entire process, from requesting quotes to signing on the dotted line, with practical NZ-specific advice throughout.
Why Getting Multiple Quotes Matters
Always get multiple quotes from qualified tradespeople — this is the single most consistent piece of advice from consumer advocates and experienced homeowners alike. Here's why it matters:
- Price variation is real. For the same scope of work, quotes can differ significantly depending on the tradesperson's overheads, availability, and how they've interpreted your brief.
- It reveals scope differences. Comparing quotes often uncovers that tradespeople have assumed different things about the job — which is valuable information before work starts.
- It gives you negotiating context. Understanding the market rate helps you have an informed conversation with your preferred tradesperson.
As a general rule, aim for at least three quotes for any job of meaningful size. For smaller jobs, two may suffice; for large or complex projects, getting four or five is worthwhile.
What to Include in Your Quote Request
The quality of a quote depends heavily on how clearly you describe the work. Before contacting tradespeople, prepare a written brief that covers:
- Scope of work — exactly what you want done, including any demolition, preparation, or finishing
- Materials — whether you want the tradesperson to supply materials, or whether you'll supply them yourself
- Site access details — parking, stairs, confined spaces, or anything that affects how long the job will take
- Timing — your preferred start date and any hard deadlines
- Consent status — whether building consent has been obtained or is still pending (see below)
Sending the same written brief to every tradesperson ensures you're comparing like with like.
How to Read and Compare Quotes
Not all quotes are structured the same way. Use this checklist when reviewing each one:
| What to check | What to look for |
|---|---|
| Scope of work | Does it match your brief exactly? What's excluded? |
| Materials specified | Brand, grade, and quantity listed? Or vague descriptions? |
| Labour vs materials breakdown | Are costs itemised or lumped together? |
| GST | Is GST included or excluded? All NZ quotes should state this clearly. |
| Payment terms | Deposit amount, progress payments, final payment on completion? |
| Timeframe | Start date, estimated duration, and what happens if it runs over? |
| Warranty | What workmanship warranty is offered, and for how long? |
| Licence or registration | Is the tradesperson's licence number included where required? |
Bold any line items you don't understand and ask for clarification in writing before accepting.
Checking Qualifications and References
Check qualifications and references before hiring — this step is non-negotiable, especially for licensed or restricted work.
Licensed and Restricted Work in NZ
Some trade work in New Zealand is legally restricted and must be carried out by a licensed professional:
- Electrical work — most electrical work must be done by a registered electrician. Check registration at the Electrical Workers Registration Board.
- Plumbing, gasfitting, and drainlaying — restricted work must be performed by a licensed practitioner. Verify at the Plumbers, Gasfitters and Drainlayers Board.
- Certain building work — work that requires a building consent must often be carried out or supervised by a Licensed Building Practitioner (LBP). Always confirm with your local council.
For any of these trades, ask to see the tradesperson's licence number and verify it on the relevant board's website before accepting a quote.
General Reference Checks
For all tradespeople, ask for:
- Two or three recent references from jobs similar to yours — and actually call them
- Proof of current public liability insurance
- Examples of previous work, ideally with photos
Understanding Building Consent Requirements
Understand building consent requirements before work begins — getting this wrong can be costly. Under the NZ Building Code, many types of work require a building consent from your local council. Some minor work is exempt under Schedule 1 of the Building Act 2004, but the exemptions have specific conditions and limitations.
Always confirm with your local council whether your project needs consent. Do not rely solely on a tradesperson's opinion on this — the legal responsibility ultimately sits with the property owner.
If consent is required, factor the cost and timeframe into your project budget. A reputable tradesperson will flag consent requirements upfront; be cautious of anyone who suggests skipping this step.
Choosing Quality Materials Suited to NZ Conditions
Use quality materials suited to NZ conditions — this is especially important given New Zealand's highly variable climate. What works well in sheltered central Auckland may fail quickly on an exposed Southland site or a coastal Bay of Plenty property.
When reviewing quotes, look at whether the materials specified are appropriate for:
- UV exposure — New Zealand has some of the highest UV levels in the world, which degrades paints, sealants, and plastics faster than in many other countries
- Wind and rain — coastal and exposed sites need products with higher weather resistance ratings
- Moisture — NZ Building Code clauses E2 (external moisture) and E3 (internal moisture) set minimum performance requirements
- Durability — Building Code clause B2 requires materials to last a minimum period without undue maintenance
Reputable suppliers like Resene, James Hardie, and Sika publish technical data sheets that specify where their products are suitable. Ask your tradesperson to reference these if you're unsure.
Planning Your Budget — Including Contingency
Plan your project budget carefully including contingency. A common rule of thumb in the NZ building industry is to add 10–20% contingency on top of your quoted costs for unexpected issues — particularly in older homes where hidden problems (rotted framing, outdated wiring, leaky pipes) are common once walls or floors are opened up.
Break your budget into:
- Quoted costs — labour and materials as per accepted quote
- Consent and inspection fees — if applicable
- Contingency — for variations and unexpected work
- Finishing costs — painting, cleaning, landscaping reinstatement that may not be in the trade quote
Get everything agreed in writing before work starts, including how variations (changes to scope) will be priced and approved.
Red Flags to Watch For
- Quote provided verbally only, with no written breakdown
- No mention of GST
- Pressure to accept immediately or lose the spot
- No licence number for restricted work
- Requests for a large upfront cash deposit with no receipt
- Unwillingness to provide references
- Price dramatically lower than all other quotes without explanation
When to Call a Professional
For any work involving electricity, gas, plumbing, or structural changes, always engage a licensed professional — this is a legal requirement in New Zealand, not just a recommendation. For other building work, a qualified tradesperson brings expertise, insurance, and accountability that protects your investment. BRANZ research consistently shows that poor workmanship is a leading cause of building defects in NZ homes.
If you're unsure whether a job is within your DIY capability, err on the side of caution — especially where the NZ Building Code or health and safety are involved. WorkSafe NZ provides guidance on safe work practices for homeowners.
