The cover that gets you on site. Protecting NZ's plumbers, sparkies, builders, and every tradie in between.
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.
Find the right cover for your trade and your projects
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.
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.
Plumbers, gasfitters, drainlayers, water specialists
Plumbers and gasfitters work with systems that can cause catastrophic damage if something goes wrong. A burst pipe repair that fails and floods a $500,000 home. A gas connection that leaks. These risks are significant and claims can be substantial. You need robust insurance.
A plumbing repair causes a pipe to burst overnight, flooding the client's kitchen and damaging cabinetry and appliances. Repair costs total $28,000. Your PLI covers the full amount, plus your legal defence costs, protecting your business from financial ruin.
Professional Note: Many councils and regions require gasfitters to be registered with engineering standards bodies. Ensure your PLI is compatible with any licensing requirements for your jurisdiction.
Electricians, data cablers, solar installers, electrical maintenance
Electrical work carries risk of serious injury and property damage. Faulty wiring can cause fires, injuries, or damage to expensive electronics and equipment. Electrical hazards are often invisible to customers, making proper documentation and insurance essential for your protection.
Faulty wiring work you completed causes a power surge that damages the client's $12,000 home theatre system. The client also claims electrical shock injury and personal injury costs of $4,000. Your PLI covers all costs, preventing a shutdown of your business.
Master Electricians: If you're a registered Master Electrician with the Master Electricians New Zealand, your PLI is a requirement for membership. Verify that your insurance meets their standards.
Interior/exterior painters, wallpaperers, plasterers, decorators
Painting and decorating work involves chemical exposure, working at heights, and the risk of accidental damage to valuable client property. Paint and chemical splashes on expensive furniture, ladder falls, and chemical burns are all realistic scenarios. Coverage is affordable and essential.
Paint splashes damage a client's expensive imported rug worth $5,000 and an antique chair worth $3,000. The client insists on compensation. Your PLI covers the $8,000 claim, maintaining your relationship with the client and protecting your cash flow.
Landscapers, arborists, gardeners, lawn mowing services, garden designers
Tree removal and landscaping work is inherently hazardous. Falling trees and branches, lawn mower thrown debris, damage to underground services, and injury during tree work all represent serious liability risks. Arborist work especially requires high coverage levels.
While removing a tree, a large branch falls and crushes a neighbour's shed worth $6,000, and damages a car parked in the neighbour's driveway ($8,000). The neighbour claims injury from the incident. Your PLI covers the full property damage and injury claim, keeping your business operating.
Air conditioning installers, refrigeration technicians, heat pump technicians
HVAC and refrigeration work involves pressurised gases, electrical systems, and water. Refrigerant leaks, electrical fires, improper installation, and water damage from cooling systems are all serious risks that require comprehensive insurance coverage.
An air conditioning installation causes water damage from a cooling line failure, flooding the client's office and damaging computers, furniture, and flooring. Total damage: $22,000. Your PLI covers the full claim without affecting your operating capital.
How much cover you need for the projects you work on
Minimum: $2M – $5M
Most homeowners and residential builders don't have strict PLI requirements, but insurance is still essential. Larger residential projects and renovation work often require minimum $2M. Premium renovations and multi-unit projects may require $5M.
Minimum: $5M – $10M
Commercial main contractors almost always require subcontractors to hold PLI. Tier 1 and Tier 2 contractors typically require minimum $5M for general trades, $10M for high-risk work like roofing and structural. Always check the project contract.
Minimum: $10M – $20M
Council-approved works and government contracts typically require high PLI limits. Infrastructure projects, public buildings, and council-led initiatives often require $10M-$20M depending on project value and risk level.
Minimum: $20M+
Large-scale construction, major infrastructure, and high-profile projects require maximum PLI coverage. Health and safety requirements are stringent, and liability exposure is substantial. Budget for premium coverage.
Pro Tip: Always ask the main contractor for their PLI requirements BEFORE quoting on work. Requirements vary by company, region, and project type. Getting the right cover from the start prevents disputes and ensures you can access work you've already quoted.
Understanding your policy coverage for construction work
Additional Coverage to Consider: In addition to PLI, most tradies also need contract works insurance (covers damage to the building during work) and tools insurance (covers stolen/damaged tools). Many brokers bundle these together at a discount. Ask about combined packages when you quote.
Get answers to questions from NZ tradies
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.
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.
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.
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.
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.
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.
Real stories from contractors protected by PLI
"During a roof repair job, loose materials fell and damaged the neighbour's car. The claim was $9,000 for repairs plus $3,000 in injury costs. My PLI covered everything instantly. Without it, I would have had to close the business to pay that claim."
"A pipe repair I completed failed and flooded the client's home, damaging carpets and furniture. The claim was $24,000. My PLI handled it without drama, and I didn't have to worry about losing my business over one mistake. It's peace of mind."
"I bid on a commercial contract that required $5M PLI. My broker helped me get the right cover without a major cost increase. That insurance meant I could access work I wouldn't have been able to otherwise. It's an investment in winning bigger contracts."
