Professional Indemnity Insurance

What Is Professional Indemnity Insurance for Sole Traders?

Professional indemnity (PI) insurance protects you when a client claims that your professional advice, services, or work caused them a financial loss. As a sole trader who provides expertise — consulting, accounting, IT, design, health advice, or any specialist knowledge — you are personally liable if your work falls short and a client suffers as a result. PI insurance covers the legal costs to defend you and any compensation you're required to pay.

Why Advice-Givers Face Serious Risk

When you sell knowledge, you take on a unique form of liability. Unlike physical property damage, a flawed recommendation or overlooked detail can have consequences that unfold months or years after the work was done — and the financial losses can far exceed your fee.

Consider:
- An IT consultant recommends a software migration that causes data loss and business disruption costing the client $200,000.
- A bookkeeper misclassifies transactions, leading to IRD penalties and interest.
- A marketing consultant advises a campaign that inadvertently infringes a competitor's trademark.

In each case, the sole trader faces a potential claim that could bankrupt them without PI insurance in place.

Claims-Made Basis: What You Must Understand

Professional indemnity policies operate on a claims-made basis. This means the policy in force when a claim is made — not when the alleged error occurred — is the one that responds. This has two important implications:

1. You need continuous cover: A gap in your PI cover could leave prior work unprotected.
2. Run-off cover matters: If you stop trading or retire, you need run-off cover for a defined period (typically 6 years) to protect against late-emerging claims.

What Activities Are Covered?

PI policies cover the professional services you declare at inception. For a sole trader this typically includes:

- Consulting and advisory services: Business strategy, management, HR, organisational advice
- Technical services: IT architecture, software development, cybersecurity consulting
- Financial services: Bookkeeping, accounting, tax preparation (though not regulated financial advice under FMCA)
- Health and wellbeing: Physiotherapy, nutrition, psychology (not regulated medical practice)
- Creative and design: Graphic design, UX/UI, architectural design, interior design
- Marketing and communications: PR, advertising, content, social media

How NZ Regulation Interacts with PI

Some professionals in NZ are required by law or their professional body to hold PI insurance:

- NZICA members (accountants): Minimum indemnity limits apply
- Engineers (IPENZ): PI required for consultancy work
- Building professionals: Licensing Board requirements may mandate PI
- Legal practitioners: Mandatory PI under the Lawyers and Conveyancers Act

Even if your profession doesn't mandate PI, many clients — especially government agencies and large corporates — contractually require it.

Choosing the Right Limit

Most sole traders choose a limit of $500,000 to $2 million. Key factors in your limit selection:

- Contract value: Your limit should exceed the largest single contract you work on.
- Client requirements: Government and enterprise clients often require $2 million or more.
- Complexity of advice: Higher-stakes or more technical advice warrants higher limits.

An adviser will help you assess the right limit for your practice.
