Business Interruption Insurance

Business Interruption insurance provides comprehensive financial support when operations are disrupted due to property damage. For property owners and landlords, coverage includes lost profits and revenue, fixed operating expenses (mortgages, rates, insurance premiums, equipment leasing), employee wages, relocation and temporary operating costs, lost rental income, and property management costs. For tenants leasing commercial space, coverage includes lost business income, ongoing rent payments required by lease agreements, increased costs of working from temporary space, moving and relocation expenses, modifications to temporary premises, customer communication costs, and lost income at temporary locations.

Coverage is triggered by physical damage to your building, denial of access by authorities, damage to neighbouring properties blocking access, supply chain disruptions at key suppliers, and utility failures caused by covered perils. The policy works alongside commercial property insurance – building coverage repairs physical damage while BI coverage protects your financial health during recovery.

When both landlords and tenants have well-structured BI policies, it maintains financial stability for the entire commercial ecosystem, ensuring neither party bears disproportionate financial strain during recovery. This coordinated protection is essential in New Zealand's unique risk environment, where earthquakes, floods, and other natural disasters can cause extended business closures.

Business interruption insurance premiums are calculated based on several key factors:

• Type of business - Higher-risk industries with complex operations or longer recovery times typically pay higher premiums than straightforward retail or office businesses
• Sum insured - The total amount of coverage you need directly impacts premium costs. Higher coverage limits for revenue, expenses, and wages result in higher premiums
• Location - Properties in areas with higher natural disaster risk (earthquake zones, flood-prone areas, coastal regions) face increased premiums
• Indemnity period - Longer coverage periods (24 or 36 months vs 12 months) increase premiums but provide essential protection for complex recoveries
• Claims history - Previous business interruption claims can significantly impact pricing, while a clean record may qualify for discounts
• Building construction and age - Older buildings or those with slower rebuild potential affect pricing due to extended recovery timeframes

Business interruption insurance in New Zealand typically costs between 0.1% to 0.5% of the sum insured amount annually.

What Is Business Interruption Insurance?

Business interruption (BI) insurance — sometimes called business income insurance or loss of profits insurance — is a specialist commercial policy designed to replace lost income and cover ongoing expenses when your business operations are disrupted due to physical damage to your property.

While commercial property insurance pays to repair or rebuild your building and replace damaged contents, it does nothing to compensate you for the revenue you lose while that work is being done. Business interruption insurance fills that critical gap, ensuring your business remains financially viable throughout the recovery period.

For New Zealand businesses, this distinction is more important than almost anywhere else in the world. Our unique natural hazard environment — earthquakes, volcanic activity, flooding, and severe weather events — means recovery periods can stretch far longer than expected. A business that only has property cover may find itself with a repaired building but no operating capital, no staff, and no customers left to serve.

Who Needs Business Interruption Insurance?

Business interruption insurance is relevant to a wide range of commercial operators across New Zealand. If your business relies on physical premises to generate income, you are exposed to business interruption risk. This includes:

• Retail businesses — shops, showrooms, and service-based retailers dependent on foot traffic and a physical location
• Hospitality operators — restaurants, cafes, bars, and accommodation providers for whom closure means immediate revenue loss
• Manufacturers and processors — businesses with complex equipment, production lines, and extended recovery timelines
• Professional service firms — offices housing critical systems, records, and equipment essential to service delivery
• Commercial landlords and property investors — property owners who rely on rental income that disappears when tenants cannot occupy
• Healthcare and medical practices — clinics and practices with specialised premises, equipment, and patient obligations
• Trades and contractors — businesses with workshops, warehouses, or depots central to their operations

Essentially, if your business would suffer financially from being unable to operate at its normal premises, business interruption insurance deserves serious consideration.

What Does Business Interruption Insurance Cover?

A well-structured business interruption policy provides comprehensive financial protection across several key areas:

• Lost gross profit — the revenue your business would have earned during the disruption period, calculated against your trading history and projections
• Fixed operating expenses — ongoing costs that continue regardless of whether you are trading, including mortgage repayments, lease payments, rates, insurance premiums, and equipment finance
• Employee wages and salaries — payroll costs to retain key staff during closure so you don't lose your workforce to competitors
• Increased costs of working — additional expenses incurred to minimise the interruption, such as operating from temporary premises, hiring substitute equipment, or using external service providers
• Relocation and fit-out costs — moving to and modifying a temporary location to continue some or all operations
• Rental income loss — for commercial landlords, lost rental income when tenants cannot occupy the property due to damage
• Property management costs — additional management fees and costs associated with managing a damaged or partially occupied property

Coverage is triggered when a defined insured event causes physical damage to property that results in a reduction in your business turnover. Common triggers include fire, flood, storm damage, earthquake, impact damage, and malicious damage.

Understanding Indemnity Periods

One of the most important — and most frequently misunderstood — aspects of business interruption insurance is the indemnity period. This is the maximum length of time for which the policy will pay out following a covered event.

Standard indemnity periods offered in New Zealand are typically 12, 18, 24, or 36 months. Choosing the right indemnity period is critical, and the Canterbury earthquakes provided a stark lesson for many NZ businesses: those who chose 12-month indemnity periods often found their coverage had expired before they were able to reopen, complete their rebuild, or restore their customer base.

When selecting your indemnity period, consider the following factors:

• Building rebuild time — in New Zealand, engineering assessments, resource consent, and contractor availability can significantly extend rebuild timelines beyond initial estimates
• Equipment lead times — specialist plant, machinery, or imported equipment may have long delivery and installation timelines
• Regulatory compliance — upgraded building codes following a major event may require significant additional work beyond simple reinstatement
• Customer and market recovery — even once physical premises are restored, rebuilding customer relationships, supply chains, and market position takes time
• Your industry's complexity — a simple retail shop and a food processing facility have very different recovery timelines

At Gerrards, we strongly recommend most New Zealand businesses consider a minimum 24-month indemnity period, with 36 months appropriate for businesses in high-risk seismic zones or those with complex operations.

How Is the Sum Insured Calculated?

Calculating the correct sum insured for business interruption insurance is more involved than for property insurance, and getting it wrong is a common — and costly — mistake. Underinsurance in BI policies can leave you with a significant financial shortfall at the worst possible time.

The sum insured for a BI policy is typically based on your business's gross profit — broadly, your turnover minus variable costs (the costs that would cease if your business stopped trading). This is multiplied by your chosen indemnity period to arrive at the sum insured.

For example: if your business generates $500,000 in gross profit annually and you choose a 24-month indemnity period, your sum insured should be approximately $1,000,000.

However, the calculation is rarely this straightforward. Factors to account for include:

• Business growth projections — your sum insured should reflect where your business will be during the indemnity period, not just where it is today
• Seasonal fluctuations — businesses with significant seasonal revenue peaks need coverage that accounts for worst-case timing of a loss event
• Wage protection requirements — if wages are to be covered separately, the sum insured should be structured accordingly
• Fixed expenses treatment — ensuring all ongoing fixed costs are captured correctly in the gross profit calculation

Gerrards' brokers work through this calculation with you carefully, drawing on your financial records and business forecasts to ensure your coverage is adequate.

Triggers and Extensions: Beyond Standard Coverage

Modern business interruption policies can be extended well beyond the basic trigger of direct physical damage to your own property. Depending on your business's vulnerabilities, the following extensions may be available and worth considering:

• Denial of access — coverage when authorities deny access to your premises following a nearby event, even if your own property is undamaged (common following earthquakes or chemical spills)
• Contingent business interruption — protection when a key supplier's or customer's premises are damaged, disrupting your own operations
• Utility failure — coverage for business interruption caused by failure of electricity, gas, water, or telecommunications supply due to damage at the supplier's infrastructure
• Prevention of access — notifiable disease — some policies can extend to include interruption caused by contagious disease at or near your premises
• Damage to nearby property — interruption caused by damage to neighbouring properties that prevents customers from reaching you

Not all extensions are available from all insurers, and the specific wording of your policy matters enormously. An experienced broker can identify the extensions most relevant to your business and negotiate appropriate coverage terms on your behalf.

Business Interruption for Commercial Landlords

Commercial property investors and landlords face a distinct set of business interruption risks compared to owner-occupiers. When a building is damaged and tenants are unable to occupy, rental income stops — but mortgage repayments, rates, insurance premiums, and property management costs do not.

Rental income protection under a BI policy for landlords typically covers:

• Lost rental income for the duration of the indemnity period while the property is being reinstated
• Lost rental income where tenants exercise break clauses in their lease due to the damage
• Property management costs that continue or increase during the recovery period
• Additional costs incurred to minimise the rental income loss, such as temporary accommodation for displaced tenants

Landlords should ensure their rental income sum insured reflects current market rental rates plus an allowance for increases over the indemnity period, and that their indemnity period is sufficient to cover the full rebuild and re-leasing process — not just the physical reinstatement.

Business Interruption for Commercial Tenants

Tenants in commercial premises face their own BI exposure, independent of whether they own the building. If a landlord's building is damaged and you can no longer operate from your leased premises, your lease agreement may still require you to pay rent — even while you're generating zero income.

A BI policy for tenants should cover:

• Lost business income during the period of displacement
• Ongoing lease payments required under the terms of your tenancy agreement
• Costs of operating from temporary premises, including fit-out modifications
• Moving and relocation expenses
• Additional marketing and customer communication costs to manage the disruption

It's worth noting that a landlord's policy protects the landlord's interests — not yours. As a tenant, you need your own business interruption coverage in place to protect your own financial position.

The New Zealand Risk Environment

New Zealand's geographic and geological characteristics create a business interruption risk profile unlike most other countries. Understanding these risks helps inform the right level of coverage for your business.

• Seismic activity — New Zealand sits on the boundary of the Pacific and Australian tectonic plates, making it one of the world's most earthquake-prone nations. The 2010-2011 Canterbury earthquakes caused extended business closures measured in years, not months.
• Flooding — increasingly frequent and severe flooding events across the North and South Islands have caused significant commercial property damage and extended closures in recent years, including the 2023 Auckland Anniversary Weekend floods and Cyclone Gabrielle.
• Fire — commercial building fires remain one of the most common triggers for business interruption claims, and in many regional areas, fire risk is elevated by proximity to agricultural land or forestry.
• Severe weather — wind, hail, and snow damage events cause regular commercial property disruption, particularly in southern and central New Zealand.
• Infrastructure fragility — New Zealand's relatively concentrated infrastructure means that damage to key roads, bridges, or utilities can prevent access to commercial premises even when the premises themselves are undamaged.

These factors reinforce why business interruption insurance is not optional risk management for serious NZ business operators — it's an essential component of any comprehensive commercial insurance programme.

Common Business Interruption Claims in New Zealand

Understanding how claims play out in practice can help business owners appreciate the real-world value of BI coverage. Common scenarios include:

• Fire at retail premises — a fire requiring 18+ months of rebuild, during which the business must pay rent on temporary premises, retain staff, and absorb marketing costs to maintain customer relationships
• Flood damage to a restaurant — water damage requiring extensive kitchen and fitout restoration, during which all revenue ceases but lease payments, supplier contracts, and staff costs continue
• Earthquake damage to an office building — structural assessments, engineering remediation, and code compliance upgrades extending closure for 2+ years, with the business needing to operate from temporary space throughout
• Denial of access following neighbouring building collapse — a business that is physically undamaged but unable to trade because authorities have cordoned off the surrounding area
• Key supplier fire — a manufacturer whose primary component supplier suffers a fire, halting their own production for months

In every case, the businesses with adequate BI coverage — the right sum insured and a sufficient indemnity period — were able to emerge from the disruption intact. Those without it frequently did not.
