The short answer
Three covers do most of the work for small NZ businesses. Key person cover pays the business a lump sum if someone it depends on dies or becomes seriously ill. Shareholder protection funds the purchase of a departing owner's shares so the business does not end up in partnership with a grieving family. Business expenses cover pays fixed overheads — rent, leases, staff — while an owner-operator is off.

Key person cover
The test is simple: if this person did not come in on Monday and never came back, what would it cost the business? For a firm where one person holds the client relationships, the technical skill or the bank's confidence, the answer is usually far more than the owner's instinct suggests — lost revenue while replacing them, recruitment, the productivity dip of a new hire, and in many cases a bank facility that is conditional on that person being there.
The policy is owned by the business and pays the business. Sizing is usually built from a revenue-contribution calculation plus recruitment and transition costs.
Shareholder protection
This is the one most often missing, and the one that causes the most damage when it is. Two or three owners build something; one dies; their shares pass to their estate. The surviving owners now have a co-owner who knows nothing about the business and needs money, and no funds to buy them out.
Shareholder protection pairs a life and trauma policy with a properly drafted buy-sell agreement so the funds and the legal obligation to transfer shares exist at the same time. The insurance without the agreement, or the agreement without the insurance, both fail.
Business expenses cover
Sits alongside personal income protection and covers the fixed costs of the business while the owner-operator cannot work: premises rent, equipment leases, accounting fees, permanent staff wages, insurance, utilities. Usually a shorter benefit period (commonly 12 months) because the purpose is to keep the doors open long enough to recover or to wind down in an orderly way.
It is particularly relevant to sole practitioners with a physical footprint — a clinic, a workshop, a studio — where the overheads keep running whether or not the owner does.
Most businesses insure the ute. Fewer insure the person driving it.
Group schemes
Once a business has a handful of staff, a group life or group health scheme is often better value per person than individual policies, and underwriting is frequently lighter or automatic up to a limit. It is also one of the few benefits a small NZ employer can offer that competes with a larger company's package.
Getting the ownership and tax treatment right
Business insurance goes wrong in structure more than in product choice. Who owns the policy, who pays the premium, who receives the proceeds and how it is treated for tax all interact — and getting it wrong can turn a tax-free personal payout into a taxable business receipt, or leave a payout in the wrong entity entirely.
This is genuinely a three-way conversation between you, your accountant and an adviser. It is not a buy-it-online product.
Common follow-up questions
Are business insurance premiums tax deductible in NZ?
It depends on the cover and who benefits. Broadly, where a policy protects revenue (key person revenue cover, business expenses) premiums are more likely deductible and proceeds assessable; where a policy protects capital (shareholder protection) the reverse is more likely. Your accountant should confirm this for your specific structure before the policy is written, not after.
How much key person cover does a small business need?
A common starting method is the person's contribution to gross profit multiplied by the number of years it would realistically take to replace them, plus direct recruitment and training costs, plus any debt personally guaranteed or conditional on them. For most owner-operated NZ businesses that lands well above the number people first guess.
We are a two-person company. Is this overkill?
Two-person companies are the highest-risk case, not the lowest. There is no bench, no redundancy of skills, and usually a personal guarantee on the lending. The exposure per person is at its maximum.
