Contractor Agreement Template For NZ Trades Businesses

Do you really need a written contractor agreement every time you bring in another tradie for a job? Yes, if you want clear expectations around workmanship, payment, safety, materials and who pays when something goes wrong.

Verbal arrangements can feel easier when you know the subcontractor, or when the job needs to start tomorrow. But in trades, small misunderstandings can become expensive fast: a variation that wasn't approved, a defect that needs rework, a customer complaint that damages your reputation, or an injury on site.

The good news is that your contractor agreement doesn't need to be complicated. It just needs to be practical, tailored to how your jobs actually run, and clear enough that everyone knows their responsibilities before work starts.

Can You Use A Contractor Agreement Template For A Trades Business?

Yes, you can use a contractor agreement template as a starting point, but it should be tailored before you rely on it for real jobs.

A generic template might cover basic payment terms and termination rights, but trades businesses usually need more detail. If you're engaging electricians, plumbers, builders, painters, landscapers, cleaners, HVAC technicians or other subcontractors, your trades subcontractor agreement should deal with site conditions, workmanship standards, tools, materials, variations, insurance and customer facing behaviour.

A good trades contractor agreement should answer questions like:

• What exact work is the subcontractor responsible for?
• What standard does the work need to meet?
• Who supplies materials, tools and equipment?
• Who is responsible for site health and safety?
• What happens if the customer asks for extra work?
• Who pays if defective work needs to be fixed?
• What insurance must the subcontractor hold?
• Can the subcontractor send someone else to do the work?

For construction work, your agreement may also need to sit alongside project documents, plans, specifications, scopes of work, payment claim processes and your obligations under the Building Act 2004, the Building Code and the Health and Safety at Work Act 2015.

A template is useful for getting organised, but it shouldn't be treated as a finished legal document. A lawyer or legal professional should tailor it to your trade, job size, customer promises and risk profile before you use it.

What Should A Trades Contractor Agreement Include?

Your agreement should include the commercial deal, the site rules and the risk allocation in one clear document.

Start with the basics: who the parties are, what the subcontractor is doing, when they need to do it, how they'll be paid and what standards apply. Then add the trade specific clauses that protect your business if the work affects a customer, a site, another contractor or your own licence obligations.

Core Clauses To Include

• Scope of work: Describe the job clearly, including plans, specifications, exclusions and any deliverables.
• Timing: Set start dates, completion dates, attendance requirements and what happens if delays occur, including any site access requirements.
• Payment: Include rates, milestones, invoicing rules, GST treatment and when invoices are payable.
• Workmanship: Require work to be carried out with due care and skill, to industry standards, and to any applicable law, code or standard.
• Licences and registrations: Require the subcontractor to hold any required licence, registration or authorisation for the trade work.
• Materials and equipment: State who supplies them, who owns them, and who is responsible if materials are damaged or unsuitable.
• Variations: Require written approval before extra work, extra costs or changes to the scope are accepted.
• Defects: Set out how defects are reported, fixed and paid for.
• Insurance: Require evidence of cover, such as public liability, vehicle, professional indemnity or other trade specific insurance where relevant.
• Health and safety: Require compliance with site safety rules and the Health and Safety at Work Act 2015.
• Customer conduct: Set rules for communication, complaints, cleanliness, smoking, pets, access and respectful behaviour on site.
• Confidentiality and privacy: Protect customer details, pricing, job notes, photos and business information.
• Liability and indemnities: Allocate responsibility for loss caused by the subcontractor's work, people or equipment.
• Termination: Explain when you can end the arrangement, including for serious safety issues, poor work, no show attendance or loss of licence.

If the subcontractor is doing regulated work, be specific. For example, electrical workers generally need to be registered and hold a current practising licence, plumbers, gasfitters and drainlayers need the right registration and licence, and restricted building work generally needs a licensed building practitioner.

How Do You Manage Defects, Variations And Customer Complaints?

You manage them by setting a clear process before the job starts, not after the customer is already upset.

Defects, variations and complaints are three of the biggest pressure points for trades businesses. They affect cash flow, customer relationships and your reputation. Your contractor agreement should give you a practical pathway when something changes or goes wrong.

Defects

Your agreement should say what counts as defective work and what the subcontractor must do to fix it. This might include work that doesn't meet the scope, plans, Building Code requirements, manufacturer instructions, industry standards or reasonable workmanship expectations.

Useful defect clauses often cover:

• how defects will be notified
• how quickly the subcontractor must inspect or fix the issue
• whether you can engage someone else if they don't respond
• whether you can recover reasonable rectification costs
• whether you can set off those costs against amounts owed, if your agreement allows it

Variations

A variation clause should make it clear that extra work, changed specifications or additional materials must be approved in writing before the subcontractor does the work or charges for it.

This matters because customers often make casual requests on site. A customer might say, "while you're here, can you also move that fitting?" Without a written variation process, your subcontractor may think they can charge you, while your customer may refuse to pay you.

Customer Complaints

Your agreement should tell subcontractors what to do if a customer complains. For example, you might require them to notify you immediately, avoid admitting liability, take photos, record what happened and refer the customer back to your business.

If you deal with residential customers, the Consumer Guarantees Act 1993 and Fair Trading Act 1986 may affect what you've promised to your customer. Your subcontractor agreement won't remove your customer obligations, but it can help you recover losses from the subcontractor if their poor work caused the issue.

How Do Payment Terms Work For Subcontractors?

Your payment terms should say exactly when the subcontractor can invoice, what they need to include, and when you can withhold or adjust payment.

For trades work, unclear payment terms can cause real tension. Some subcontractors expect weekly payment. Others invoice at milestones. Some supply materials and need reimbursement. If your customer hasn't paid you yet, you may still be expected to pay your subcontractor unless your agreement says otherwise and the arrangement is legally effective.

Your agreement should cover:

• hourly, daily, fixed fee, per job or milestone pricing
• whether rates include GST or are plus GST
• what timesheets, photos, completion records or signed job sheets are required
• when invoices can be issued
• how many days you have to pay valid invoices
• whether materials need pre approval
• what happens if work is incomplete, defective or outside scope
• whether you can set off rectification costs or other amounts, if drafted clearly

If the work is construction work, the Construction Contracts Act 2002 may apply. That Act has rules about payment claims, payment schedules and adjudication. Your agreement should be consistent with any payment claim process you use, especially if you're working on building or infrastructure projects.

Example: A Variation That Needs A Paper Trail

Mike runs a small plumbing business in Hamilton. He engages Jess, an independent plumber, at $90 plus GST per hour for a bathroom renovation. The agreement says Jess can work up to 35 hours unless Mike approves extra time in writing. Materials over $300 must also be approved first.

On site, the customer asks Jess to swap two fixtures and add an extra outdoor tap. Jess texts Mike before doing the work. Mike approves 4 extra hours and $420 plus GST in materials, then sends the customer a written variation.

Because the agreement had a clear variation process, Jess gets paid for the approved extra work, Mike can charge the customer, and no one is arguing at the end of the job about who agreed to what.

How Do You Avoid Accidentally Creating An Employment Relationship?

You reduce the risk by making sure the written agreement and the working relationship both reflect a genuine contractor arrangement.

Calling someone a contractor doesn't automatically make them one. Under the Employment Relations Act 2000, the real nature of the relationship matters. If a person is treated like an employee, they may later claim employee rights, such as minimum employment standards, leave entitlements, holiday pay or personal grievance rights.

The contractor gateway test came into law on 21 February 2026 and isn't retrospective. If all gateway criteria are met, the worker is treated as a specified contractor for employment status purposes. The criteria include a written agreement stating the person is an independent contractor or not an employee, the ability to work for others, either control over when they work or a permitted right to subcontract subject only to limited vetting, no termination for declining additional work, and a reasonable opportunity to seek independent advice before signing. If the gateway test isn't met, the common law real nature of the relationship test may still apply.

In practice, your trades contractor arrangement is more likely to look genuine where the subcontractor:

• has their own NZBN or business structure
• quotes or invoices for work
• can accept or reject jobs
• can work for other clients, including outside your business
• uses their own tools, vehicle and equipment where appropriate
• carries their own insurance
• is responsible for fixing their own defective work
• can delegate or subcontract work if the agreement allows it and licensing rules are met
• is paid for results, milestones or agreed time rather than being rostered like staff

Be careful with daily control. If you require fixed hours, exclusive service, uniforms, detailed supervision, ongoing rosters and personal performance of every task, the relationship may start to look more like employment.

If you need someone to work like part of your team long term, an employment agreement may be the cleaner option.

Contractor Agreement Template Outline For Trades Businesses

Use this outline as a drafting checklist, not as a finished contract. The final agreement should be tailored to your trade, job types, insurance, customer terms and legal obligations.

1. Parties: Insert your business details, NZBN if you have one, and the subcontractor's legal name or company details.
2. Engagement: State that the subcontractor is engaged under a contractor agreement as an independent contractor, not an employee, and describe how jobs will be offered and accepted.
3. Scope Of Work: Attach or describe the work, plans, specifications, exclusions, site address and expected deliverables.
4. Standards And Compliance: Require compliance with laws, codes, licences, permits, manufacturer instructions, trade standards and your reasonable site directions.
5. Timing And Attendance: Set start dates, completion dates, site access rules, delay notification rules and any key milestones.
6. Payment And Invoicing: Add the rate, GST position, invoice process, required records, payment timing and what happens if work is incomplete or defective.
7. Materials, Tools And Equipment: State who supplies each item, who approves purchases, and who is responsible for loss, damage, storage and waste.
8. Variations: Require written approval before any change to scope, timing, price, materials or method.
9. Defects And Rectification: Set the defect notice process, rectification timeframes and your rights if the subcontractor doesn't fix the issue.
10. Health And Safety: Require compliance with the Health and Safety at Work Act 2015, site safety plans, incident reporting and any PPE requirements.
11. Insurance: List required policies and minimum cover types, and require certificates of currency before work starts.
12. Customer Conduct: Set expectations for communication, complaints, cleanliness, photos, access, smoking, pets and respectful conduct.
13. Confidentiality, Privacy And IP: Protect customer information, business processes, pricing, photos, drawings and any intellectual property created or used.
14. Liability And Indemnity: Allocate responsibility for loss caused by the subcontractor, their workers, their equipment or defective work.
15. Subcontracting And Personnel: Say whether the contractor can send someone else, and require any replacement person to be qualified, insured and approved where needed.
16. Suspension And Termination: Set when you can pause or end the arrangement, including for safety breaches, serious defects, non attendance or loss of licence.
17. Records: Require timesheets, job sheets, photos, compliance certificates, warranties, receipts and completion evidence where relevant.

Before you send it out, compare the agreement with your customer terms. If you've promised your customer a 12 month workmanship warranty, a 5 business day defect response time or a fixed completion date, your subcontractor agreement should help you deliver on that promise.

Key Takeaways

• A written contractor agreement helps you manage job standards, payment, safety, materials, defects and customer complaints.
• Trades contracts need more than a basic template. They should deal with site specific risks, regulated work, insurance and variations.
• Defects and variations are much easier to manage when your agreement sets a clear approval and rectification process.
• Payment terms should match how your jobs run, including milestones, GST, invoices, materials and any Construction Contracts Act 2002 process.
• Your agreement and working practices should support a genuine contractor relationship, including under the contractor gateway test that came into law on 21 February 2026.
• A template is a helpful start, but it should be tailored before you rely on it for live jobs.
