A written flooring installation contract is one of the most important documents you'll sign during a home renovation. It sets clear expectations for both you and your installer, and gives you a solid foundation if anything goes wrong. In New Zealand, consumer protection law and good trade practice both support having everything in writing before work begins.
Why a Written Contract Matters
Verbal agreements can lead to misunderstandings about scope, cost, and timelines. A written contract creates a clear record that both parties have agreed to the same terms. Under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986, tradespeople must carry out work with reasonable care and skill — but a contract makes it much easier to enforce those rights if a dispute arises. Consumer NZ has useful guidance on your rights when hiring tradespeople.
Key Elements Every Flooring Contract Should Include
1. Full Details of Both Parties
The contract should clearly state your full name and address, and the installer's full legal business name, physical address, phone number, and email. If the installer is a company, include the company registration number.
2. Detailed Scope of Work
This is the heart of the contract. It should describe:
- Which rooms or areas are being covered
- The type of flooring being installed (e.g. engineered timber, LVP, carpet, ceramic tile, cork)
- The brand, product name, and colour of the flooring material
- Subfloor preparation required — levelling, moisture barrier, removal of existing flooring
- Underlay type and specification if applicable
- Trims, transitions, and skirting — whether these are included or excluded
Being specific here prevents disputes about what was and wasn't agreed. For example, if you're using a product from a supplier like Bunnings or Mitre 10, note the exact product name.
3. Materials Supply — Who Provides What?
Clearly state whether the installer is supplying the flooring material, or whether you are purchasing it separately. If the installer is supplying materials, list the quantities, unit costs, and total material cost separately from labour. This transparency helps you compare quotes and understand what you're paying for.
4. Pricing and Payment Terms
The contract must include:
- Total price (GST-inclusive in NZ)
- Payment schedule — for example, a deposit on signing, a progress payment, and the balance on completion
- What triggers each payment — never pay the full amount upfront
- How variations are handled — if extra work is needed (e.g. subfloor repairs), the process for agreeing on additional costs in writing before work proceeds
As a rough guide, deposits of 10–30% are common in the NZ trade industry, though this varies. Be cautious of any installer asking for more than 50% upfront.
5. Start Date and Estimated Completion
Include the expected start date and a realistic completion timeframe. Note any factors that could affect timing, such as material delivery delays or weather (relevant for exterior decking). If a firm completion date is critical for you — for example, before tenants move in — state that clearly.
6. Subfloor and Site Conditions
Flooring installation is heavily affected by subfloor condition and moisture levels. The contract should outline:
- Who is responsible for assessing and preparing the subfloor
- What happens if unexpected issues (e.g. moisture, rot, unevenness) are discovered
- Acceptable moisture readings before installation proceeds
This is especially important in New Zealand's varied climate — from the damp winters of the South Island to the humidity of Northland. BRANZ provides technical guidance on moisture management in NZ buildings.
7. Product Warranties and Workmanship Guarantee
A good contract will reference:
- The manufacturer's product warranty (e.g. wear warranty on LVP or engineered timber)
- The installer's own workmanship warranty — how long, and what it covers
- Any conditions that could void the warranty (e.g. incorrect cleaning products, flooding)
Always ask for warranty documents in writing, separate from the contract.
8. Waste Removal and Site Clean-Up
Who removes offcuts, old flooring, and packaging? Confirm this is in the contract. Leaving a site clean is standard professional practice, but it's worth spelling out.
9. Dispute Resolution Process
Include a simple process for raising concerns — for example, issues must be raised in writing within a set number of days of completion. Many NZ tradespeople use the Disputes Tribunal for unresolved contract disputes (check the current jurisdictional limit with the Disputes Tribunal). Knowing this process in advance keeps things civil.
10. Health and Safety Obligations
Under the Health and Safety at Work Act 2015, both the homeowner and the contractor have duties. The contract can note that the installer is responsible for their own safe work practices on site. WorkSafe NZ has guidance on managing contractors safely.

When to Call a Professional
Flooring installation itself is not restricted trade work in New Zealand — it doesn't require a licence the way electrical or plumbing work does. However, if your flooring project involves underfloor heating, an electrician registered with the Electrical Workers Registration Board (EWRB) must carry out the electrical connections. Similarly, if subfloor drainage or plumbing is involved, a licensed tradesperson registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB) is required.
For the flooring installation itself, look for an experienced, reputable installer. You can find qualified local flooring professionals on tradedirectory.co.nz. Always ask for references, check their previous work, and — most importantly — get that contract signed before anyone lifts a plank.
