What is Underinsurance?

Underinsurance occurs when your insurance coverage is insufficient to cover the full cost of replacing or repairing your business assets. In New Zealand, this is a particularly critical issue due to our unique geological and economic conditions.

The 80% Rule Explained

Many New Zealand insurance policies include an 80% co-insurance clause. This means:

  • Your policy requires you to insure for at least 80% of the replacement value
  • If you insure for less, your claim may be reduced proportionally
  • A building worth $1M insured for $600K may only receive $600K even with a full loss

Properly Insured

Full replacement value covered, with adequate business interruption and liability protection.

Underinsured

Gaps in coverage that could result in significant out-of-pocket expenses during a claim.

Common Causes of Underinsurance

Understanding why underinsurance occurs helps you identify potential gaps in your own coverage.

Inadequate Sum Insured

Failing to insure assets for their full replacement value, often due to underestimating reconstruction costs or not accounting for inflation.

Outdated valuations

Not updating valuations regularly to reflect current market conditions, construction costs, or business growth.

Incomplete cover

Overlooking essential coverage types or failing to account for all business assets, including intangible assets.

Policy exclusions

Not understanding policy exclusions, particularly around natural disasters, flood damage, or specific types of loss.

Underestimating business interruption

Failing to calculate the true cost of interrupted operations, including lost revenue, fixed costs, and recovery expenses.

Contents vs Building confusion

Not distinguishing between building and contents coverage, leaving valuable equipment or fit-out items uninsured.

New Zealand-Specific Risks

New Zealand's unique geological and geographic conditions create specific underinsurance risks that business owners must understand.

Earthquake Risk

New Zealand experiences thousands of earthquakes annually. The 2011 Christchurch earthquake demonstrated how quickly businesses can face catastrophic losses.

Flooding

Areas like Canterbury, Waikato, and Hawke's Bay face significant flood risks. Standard policies often have separate flood exclusions or limits.

Volcanic Activity

New Zealand's volcanic zone presents unique risks. Business interruption from volcanic activity may not be covered under standard policies.

Cyclones

Northland and Auckland are increasingly affected by tropical cyclones, causing widespread damage to commercial properties.

High Construction Costs

NZ has some of the highest construction costs globally. Rebuilding after a disaster can far exceed original valuations.

EQC Cover Limits

The Earthquake Commission (EQC) provides natural disaster cover for residential and commercial properties, but with caps:

  • Building cover capped at $100,000 + GST (residential)
  • Contents cover capped at $20,000 + GST (residential)
  • Land cover varies but is also capped

These limits are often far below actual replacement costs, making additional insurance essential for NZ businesses.

Consequences of Being Underinsured

The impacts of underinsurance can be devastating for New Zealand businesses. Understanding these consequences emphasises why adequate coverage is essential.

Personal Financial Liability

High

Business owners may be personally liable for gaps in coverage, putting personal assets at risk including family homes.

Cash Flow Crisis

High

Unexpected shortfalls between insurance payouts and actual costs can create severe cash flow problems during recovery.

Business Closure

Critical

In severe cases, underinsurance can lead to business failure when owners cannot afford to rebuild or replace essential assets.

Insufficient EQC Cover

High

Many NZ business owners rely solely on EQC for natural disaster cover, but EQC has strict caps that may not cover full replacement costs.

Legal Liability

Critical

Inadequate liability insurance can expose businesses to costly legal claims that could bankrupt the company.

Staff Impact

Medium

Business failure or layoffs due to underinsurance affect employees, families, and the local community.

Real Example: The Cost of Underinsurance

Consider a Christchurch retail business with a building valued at $800,000 but insured for only $500,000. After the 2011 earthquake:

$500,000

Insurance Payout

$800,000

Actual Rebuild Cost

$300,000

Shortfall (Business Owner Pays)

How to Avoid Underinsurance

Taking proactive steps to ensure adequate coverage protects your business from unexpected financial hardship.

Essential Steps

Engage a registered valuer to assess your property and assets at current market values.

Account for lost revenue, fixed costs, and recovery time when setting coverage limits.

4

Document Everything

Maintain detailed records of assets, stock, equipment, and their values for accurate coverage.

5

Work with a Broker

Insurance brokers have expertise in assessing adequate coverage levels for NZ businesses.

The Importance of Regular Valuations

New Zealand's property values and construction costs change significantly over time, making regular valuations essential.

When to Get a Valuation

Every 2-3 Years

At minimum, get a professional valuation every 2-3 years to ensure your coverage keeps pace with market changes.

After Major Renovations or Expansions

Any significant upgrade to your business premises or addition of valuable equipment warrants a new valuation.

After Significant Market Changes

Major events like the Christchurch or Kaikoura earthquakes dramatically changed property values in affected regions.

Before Purchasing or Leasing New Property

Understanding the replacement value helps you determine appropriate insurance coverage before committing to a new premises.

Don't Rely on Rateable Value

Many New Zealand business owners mistakenly rely on their Council rateable value or GST-inclusive purchase price for insurance purposes. These figures often bear little relation to actual replacement costs:

  • Rateable values are based on market assessments, not rebuild costs
  • They exclude demolition costs, professional fees, and GST
  • They don't account for increased construction costs since the valuation date

Key Takeaways

Underinsurance is a serious risk for NZ businesses, with potential gaps leading to significant financial loss during a claim.

New Zealand's unique risks - earthquakes, floods, volcanoes, and high construction costs - make adequate coverage particularly critical.

EQC cover has strict caps that rarely cover full replacement costs - additional insurance is essential.

Regular professional valuations every 2-3 years help ensure your coverage matches current replacement costs.

Working with an experienced insurance broker helps identify coverage gaps and ensures appropriate limits.
