Trade Contractor Insurance

The cover that gets you on site. Protecting NZ's plumbers, sparkies, builders, and every tradie in between.

Site Access Starts with Insurance

In New Zealand, public liability insurance isn't just smart business — it's often mandatory. Most main contractors won't let you set foot on a building site without proof of PLI. Whether you're wiring a new build in Tauranga or fixing pipes in Dunedin, the right cover keeps you working.

Construction and trade work is high-risk by nature. Property damage from your work, injuries to passersby or workers, fallen debris, water damage from repairs — these incidents can happen to any tradie at any time. One mistake can cost tens of thousands of dollars in claims and legal fees. PLI is the difference between a sustainable business and a closed business.

The good news? Getting the right insurance is straightforward, and rates for tradies are competitive. Your broker can help you understand exactly what cover you need based on the projects you work on and the main contractors you work with. Once you're insured, you're equipped to bid on more work, win bigger contracts, and scale your business with confidence.

NZ tradies know the value of doing things properly. Do the same with your insurance.

Construction site with builders

Builders & Construction

Builders, carpenters, roofers, scaffolders, concreters, demolition specialists

Building and construction are the highest-risk trades. You're working at heights, with heavy equipment, near public areas, and on projects that affect neighbouring properties. One dropped tool, one collapsed scaffold, one water leak into a neighbour's home can result in claims exceeding $100,000.

Key Risks:

  • Property damage from construction work
  • Falling debris and dropped tools injuring passersby
  • Structural damage to adjacent properties
  • Water damage from roof repairs or plumbing work
  • Scaffold collapse and falling materials
  • Vehicle damage to client property
  • Injury to workers on site (ACC + PLI)
  • Noise and dust complaints causing business loss
Recommended Cover: $5M – $10M
Typical Monthly Cost: From ~$60

Real Scenario:

During roofing work, loose materials fall from scaffolding and damage a neighbour's car and fence. Repairing the damage costs $8,000. The neighbour claims injury from the falling debris: $6,000 in medical costs. Your PLI covers all $14,000 plus legal defence costs.

Site Requirements: Most main contractors require builders and subcontractors to have $5M-$10M PLI. Major commercial projects may require $20M. Always check contract requirements before quoting on work.

Trade Contractor Insurance: Frequently Asked Questions

Get answers to questions from NZ tradies

Is PLI mandatory for tradies in NZ?

PLI is not legally mandatory for all tradies, but it is practically mandatory if you work on building sites. Most main contractors require subcontractors to hold PLI before allowing them on site. Without it, you cannot access most commercial and residential construction work.

How much cover do I need as a subcontractor?

Site requirements vary. Residential work typically needs $2M-$5M. Commercial projects often require $5M-$10M. Large infrastructure projects may require $10M-$20M. Check your main contractor's requirements or ask your insurance broker to assess your needs.

Does PLI cover defective workmanship?

No. PLI covers injury to third parties and damage to their property. It does not cover the cost of fixing your own poor-quality work. You need contract works insurance or a workmanship warranty for that. These are separate from PLI.

What about tools and equipment cover?

PLI does not cover your tools or equipment if they're stolen or damaged. You need separate tools insurance. Many insurance brokers can bundle this with your PLI for a combined quote, often saving you money on both policies.

Do I need PLI as a sole trader?

Yes. As a sole trader, you are personally liable for any claims. PLI protects your personal assets from business liabilities. Most site access requirements don't distinguish between sole traders and companies — PLI is required regardless of your business structure.

What's the difference between PLI and contract works insurance?

PLI covers injury to people and damage to third-party property. Contract works insurance covers damage to the building project itself while you're working on it (e.g., damage to newly installed systems). Many tradies need both for complete protection.
