What Insurance Do Contractors Need?
The insurance you need as a contractor depends on your trade, the contracts you work under, and whether you employ staff. At a minimum, most contractors need public liability insurance. Many also need professional indemnity — especially if you provide advice, design, or technical services.
Public Liability
EssentialCovers claims for bodily injury or property damage caused by your work. If you accidentally damage a client's property or a third party is injured at your work site, public liability responds. Required by most commercial contracts.
Professional Indemnity
Essential for advice/designCovers claims arising from errors, omissions, or negligent advice. Critical for IT contractors, engineers, architects, consultants, and anyone whose work product could cause a client financial loss.
Statutory Liability
RecommendedCovers fines and legal costs from unintentional breaches of NZ legislation such as the Health and Safety at Work Act 2015. Particularly important if you work on construction sites or in hazardous environments.
Business Interruption
OptionalCovers lost income if your business is disrupted by an insured event — such as a fire at your premises or a natural disaster preventing you from working. Relevant for contractors with fixed overheads or staff.
ACC Does Not Cover Property Damage or Financial Loss
ACC covers personal injuries only. It does not cover damage you cause to a client's property, financial losses from your errors, or your legal defence costs. Contractors need separate business insurance for these risks.
Contractor vs Employee: Why You Need Your Own Cover
One of the most common mistakes contractors make is assuming their client's insurance covers them. It does not. As an independent contractor, you are responsible for your own insurance — and your own liabilities.
| Coverage | Employee | Contractor |
|---|---|---|
| Employer's public liability | ||
| Employer's PI cover | ||
| ACC levies paid by employer | ||
| Statutory liability cover | ||
| Personal assets protected |
NZ Employment Law Note: Inland Revenue applies a set of tests to determine whether a worker is genuinely a contractor or an employee. If you are found to be an employee in substance (regardless of what your contract says), your "client" becomes your employer and takes on employer obligations. However, this does not mean you are automatically covered by their insurance — the determination is separate. Always maintain your own cover.
IT Contractor Insurance
IT and technology contractors face unique risks. A software bug, data breach, or project failure can cause significant financial loss to your client — and professional indemnity insurance is your primary defence.
Professional Indemnity
Covers coding errors, project failures, missed deadlines, and negligent technical advice. Most IT contracts require $1-2M in PI cover.
Cyber Liability
Covers data breaches, privacy incidents, and cyber events. If you handle client data or have access to their systems, cyber liability is increasingly expected.
Public Liability
Covers property damage or injury at client premises. Even office-based IT contractors need this — tripping over cables, spilling coffee on a server, or damaging equipment.
Illustrative Example: IT Contractor Claim
An IT contractor deploys a software update to a client's e-commerce platform. The update contains a bug that takes the site offline for 48 hours during a peak trading period. The client claims $85,000 in lost revenue and additional costs to fix the issue.
With professional indemnity insurance, the contractor's insurer covers the legal defence costs and any settlement or judgment — up to the policy limit. Without insurance, the contractor would face this claim personally.
Illustrative example only. Actual coverage depends on policy terms and conditions.
Construction Contractors
Construction contractors face higher physical risks and typically need more comprehensive cover than office-based contractors. Public liability limits of $2-5 million are standard, and contract works insurance may also be required.
What Construction Contractors Need
- Public liability ($2M-$10M depending on contract)
- Contract works / builders risk insurance
- Tools and equipment cover
- Statutory liability (Health and Safety at Work Act)
- Motor vehicle insurance for work vehicles
NZ Building Act Considerations
Under the Building Act 2004, contractors performing restricted building work must be Licensed Building Practitioners (LBPs). While insurance is not a legal requirement for LBPs, it is a practical necessity.
The 10-year liability period under the Building Act means claims can arise long after a project is completed. Run-off cover (which extends your PI insurance after you stop trading) is worth considering.
Contract Requirements: What Clients Expect
Before engaging a contractor, most NZ businesses require proof of insurance. Here is what you will typically be asked to provide — and the cover limits clients expect.
Certificate of Currency (COC)
A COC is a document from your insurer confirming you hold active insurance, the type of cover, and the policy limits. Most clients will request a COC before signing a contract. Your insurer or broker can issue one — usually free of charge and within 24 hours.
Typical Cover Limits by Client Type
| Client Type | Public Liability | Professional Indemnity |
|---|---|---|
| Small business | $1M | $500K-$1M |
| Medium business / corporate | $2M-$5M | $1M-$2M |
| Government / local council | $5M-$10M | $2M-$5M |
| Construction / infrastructure | $5M-$20M | $2M-$10M |

Sole Trader vs Company: Insurance Differences
Your business structure affects your insurance needs — particularly your personal exposure to risk.
Sole Trader Contractors
As a sole trader, there is no legal separation between you and your business. If your business is sued, your personal assets — home, car, savings — are at risk. Insurance is arguably more important for sole traders than for company operators.
- Personal assets at risk in a claim
- No corporate veil protection
- Typically lower premiums (lower revenue)
- Simpler policy structures
Company Contractors
Operating through a limited company provides some personal asset protection. However, directors can still be held personally liable in certain situations — and most clients still require the company to hold insurance.
- Limited liability protects personal assets (usually)
- Directors can still face personal claims
- May need directors & officers (D&O) cover
- Higher premiums if company has employees
Frequently Asked Questions
Common questions about contractor insurance in New Zealand.
Do contractors need their own insurance in New Zealand?
Yes. Unlike employees, contractors are not covered by their client's insurance policies. If you cause damage or a third party is injured because of your work, you are personally liable. Most commercial contracts in NZ require contractors to hold public liability and often professional indemnity insurance before work can begin. ACC covers personal injuries but does not cover property damage, financial loss claims, or legal defence costs.
What insurance do IT contractors need in NZ?
IT contractors typically need professional indemnity insurance (covers claims from coding errors, data loss, project failures, or bad advice), public liability insurance (covers physical injury or property damage at client sites), and cyber liability insurance (covers data breaches and privacy incidents). Most IT contracts in NZ require $1-2 million in professional indemnity cover. If you handle sensitive data, cyber liability is increasingly expected.
How much does contractor insurance cost in NZ?
Contractor insurance costs vary by trade and risk level. IT and consulting contractors typically pay $40-$80/month for a combined public liability and professional indemnity package. Trades contractors (builders, electricians, plumbers) pay more — typically $80-$200/month — due to higher physical risk. Cleaning and maintenance contractors usually pay $30-$60/month. Prices are indicative and depend on revenue, cover limits, and claims history.
What is the difference between contractor insurance and employee insurance?
Employees are covered by their employer's insurance policies, ACC levies, and statutory protections. Contractors must arrange and pay for their own insurance. If you operate as an independent contractor — whether sole trader or through a company — you need your own public liability, professional indemnity, and potentially statutory liability cover. Your client's policy will not extend to cover your negligence or errors.
What public liability limit do clients typically require from contractors?
In New Zealand, most commercial contracts require contractors to hold $1 million to $5 million in public liability cover. Government contracts and large corporates often require $5 million or $10 million. The required limit depends on the nature of the work and the potential for damage. Construction and trades contractors are typically required to carry higher limits than office-based consultants or IT contractors.
Can I get contractor insurance as a sole trader?
Yes. Most NZ insurers offer policies for sole trader contractors. You do not need to operate through a company to get public liability or professional indemnity insurance. In fact, sole traders arguably need insurance more than company operators because there is no corporate veil — your personal assets are at risk if you are sued as a sole trader. Premiums for sole traders are typically lower due to smaller revenue and fewer employees.
