Yes, it is perfectly legal for a driveway layer in New Zealand to subcontract parts of your job to other tradespeople or contractors. This is standard practice in the construction industry. However, there are important rules about licensed and restricted work, your contractual rights, and what you should expect to be told upfront.
Why Subcontracting Is Common in Driveway Work
A driveway project often involves more than one trade. Depending on the scope, your driveway layer may need to bring in specialists for:
- Excavation and earthworks – machine operators for digging and grading
- Concrete placement – concrete truck drivers and finishing crews
- Drainage and stormwater – connecting to existing systems or installing new channels
- Kerbing and edging – specialist kerb-laying equipment and operators
- Line marking or sealing – for asphalt or chip-seal surfaces
Rather than employing all of these people directly, your main contractor will often engage subcontractors who specialise in each area. This is efficient and normal.
What the Law Says About Subcontracting
There is no law in New Zealand that prevents a driveway layer from subcontracting. However, several important legal points apply:
Restricted and Licensed Work Must Be Done by Qualified People
Certain parts of a driveway project touch on restricted building work or licensed trades. For example:
- Drainage and stormwater connections that tie into the public network or a building's drainage system are restricted work under the Plumbers, Gasfitters, and Drainlayers Act 2006. This work must be carried out or supervised by a licensed drainlayer registered with the Plumbers Gasfitters & Drainlayers Board.
- Any electrical work — such as installing driveway lighting or gate motor wiring — is restricted work and must be done by a registered electrician under the Electrical Workers Registration Board.
- If the driveway work involves structural retaining walls over certain heights, a Licensed Building Practitioner (LBP) may need to be involved. Check with your local council and the Licensed Building Practitioners register.
Your main contractor is responsible for ensuring any subcontractors they engage for restricted work hold the correct licences. You are entitled to ask for proof.
Building Consent and Schedule 1
Many residential driveways fall under Schedule 1 exemptions of the Building Act 2004 and do not require a building consent. However, this depends on factors like retaining wall height, proximity to boundaries, and stormwater management. Always confirm with your local council before work begins — do not rely solely on your contractor's advice on this point. MBIE Building Performance has useful guidance on when consent is required.
Your Rights as a Homeowner
Even though subcontracting is legal, you have important rights:
- You should be informed. A reputable contractor will tell you upfront if they plan to subcontract significant portions of the work. Ask about this before signing anything.
- Your contract is with the main contractor. If a subcontractor does poor work, your legal claim is against the company or person you hired — not the subcontractor directly. Make sure your contract is in writing.
- Quality and liability remain with the head contractor. They are responsible for the standard of all work carried out under their contract, including by subcontractors.
- Consumer protections apply. The Consumer Guarantees Act and Fair Trading Act both apply to trade services in NZ. Consumer NZ has helpful plain-English guidance on your rights.
What to Include in Your Contract
Before work starts, make sure your written contract covers:
| Item | Why It Matters |
|---|---|
| Scope of work | Clearly defines what is included |
| Subcontracting disclosure | Who will be doing each part of the job |
| Licence requirements | Confirms licensed trades will be used where required |
| Payment terms | Protects both parties |
| Defects liability period | Ensures you can claim for faults after completion |
| Consent responsibilities | Who is responsible for obtaining any required consents |
Red Flags to Watch For
- A contractor who refuses to disclose who will be doing the work
- Subcontractors arriving on site who cannot show a licence for restricted work
- No written contract or quote provided
- Pressure to pay large deposits upfront before any work begins
When to Call a Professional
For any driveway project involving drainage connections, retaining structures, or electrical work, always ensure the relevant licensed professional is involved. If you are unsure whether your project needs a building consent, contact your local council directly. For the construction work itself, you can find qualified, local driveway layers and related tradespeople on tradedirectory.co.nz.
Safety note: Earthworks and excavation can be hazardous. Ensure your contractor follows WorkSafe NZ guidelines, particularly around trenching, underground services, and machinery on site.
