Business interruption

Business interruption insurance in NZ

Business interruption insurance is designed to help with defined financial losses when an insured event disrupts normal trading. It commonly works alongside commercial property or material damage cover, so a closed shop or a drop in revenue does not automatically mean the policy will respond.

The short answer

Business interruption cover deals with the financial effect of an interruption, not the cost of repairing the damaged building, stock or equipment. Business.govt.nz explains that the cover can apply when an event insured under a commercial property material damage policy, such as fire, natural disaster or burglary, interrupts the business and causes a loss.

The policy schedule and wording still decide the trigger, what is measured, the maximum amount, the period of cover and any exclusions. Some policies include extensions for events away from the insured premises, but those extensions are not a general promise that every supplier, customer, utility or access problem is covered.

Start with the event that triggers the cover

A useful way to read business interruption insurance is to begin with the event, then follow the financial consequences. If insured physical damage stops or reduces trading, the material damage section may address the property loss while the business interruption section may address defined income loss and additional costs.

That link matters. A voluntary closure, a general fall in demand, a key person's absence or a cyber incident may not meet a standard property-linked trigger. Separate wording or another type of cover may be needed. Do not rely on the label alone; ask where the trigger is written and what evidence would show that it occurred.

  • Which event or damage must happen before the business interruption section can respond?
  • Does the material damage need to be at the insured premises?
  • Are access, supplier, customer or utility extensions included, and what limits or distances apply?
  • Are cyber interruption and key-person absence handled under separate policies?
  • Which exclusions, waiting periods or excesses apply to the event?

What the policy may measure after an interruption

Business interruption policies often refer to gross profit, gross income, wages, fixed expenses or increased costs of working. These terms can have policy definitions that differ from everyday accounting language. The figure shown in a set of accounts should not be copied into an insurance schedule without checking the policy formula.

The Insurance Council of New Zealand explains that a business may still need to pay staff, rent and power while it is interrupted. It also gives examples of extra costs that may help maintain income, such as using contractors or temporary premises. The actual policy decides which costs qualify, how savings are treated and whether approval is needed before extra spending is incurred.

  • Income or gross profit lost because of the insured interruption.
  • Wages, rent, utilities and other continuing expenses listed by the policy.
  • Reasonable additional costs used to reduce the interruption or keep trading.
  • Operating costs saved while the business is partly or fully closed.
  • Limits, sub-limits, excesses and claim-preparation costs stated in the schedule.

The indemnity period needs a recovery timeline

The indemnity period is the maximum period over which the policy can measure a covered interruption, subject to its terms and limits. It should be considered against the time needed to repair or replace property, obtain consents, replace specialist equipment, restock, retrain staff and rebuild normal sales or production capacity.

Reopening the doors is not always the same as returning to the expected level of trade. On the other hand, choosing a longer period does not guarantee that every loss throughout that period will be paid. The event, loss and policy calculation still need to fit the wording.

  • How long would design, consent, repair or rebuilding realistically take?
  • Is specialist machinery available locally, and what is the replacement lead time?
  • Could the business use temporary premises or outsourced production?
  • How long would customers and normal capacity take to return?
  • When were these assumptions last tested with current suppliers and records?

Prepare business records before choosing figures

Current records make the discussion more reliable. Bring recent financial statements, management accounts or revenue summaries, payroll, rent and finance commitments, major supplier and customer dependencies, stock levels, equipment lead times and the existing policy schedule. Separate confirmed figures from estimates.

Business.govt.nz recommends reviewing insurance needs at least annually and specifically warns against letting business interruption cover roll over unchanged when revenue is growing. A review is also useful after moving premises, adding equipment, changing suppliers, hiring staff, taking on a major contract or changing the way the business earns income.

Questions to ask before relying on the cover

Ask for important explanations in writing and keep them with the policy schedule. FMA guidance on general insurance encourages regular reviews and written answers about available options and the implications of change. Personal recommendations should only follow a review of the business, the policy wording, the budget and the relevant accounting information.

This article is general information, not a coverage opinion or a claim assessment. An insurer, adviser, accountant or claims specialist may need to confirm different parts of the answer for a particular business or event.

  • What insured event links the material damage and business interruption sections?
  • How does this wording define gross profit, gross income and increased cost of working?
  • Which ongoing expenses and wages are included, limited or excluded?
  • Why was this indemnity period selected, and which recovery assumptions support it?
  • Which dependencies and extensions are included, and what sub-limits apply?
  • What records would be needed after an interruption, and who should be contacted first?
