Every question, every answer, every source

In New Zealand, when water enters a home during severe weather, the most important contents insurance policy clauses are those that determine whether the water damage is covered, what items are insured, and how much your insurer will pay.

The key distinction is between damage caused by flooding or surface water, rain entering through a damaged roof or window, and water escaping from plumbing. These can be treated differently under the same policy.

The most important clauses to check

1. Storm, flood and surface-water cover

Look for wording that explicitly covers storm or flood damage. Check whether it includes rainwater runoff, overland flow, surface water and water entering through doors or other openings. Do not assume every type of flooding is covered simply because the policy says “flood”.

Why it matters: the source and path of the water can affect whether the claim is accepted. HouseholdersNZI Distinction Contents Insurance Policy WordingWhat Home, Contents & Car Insurance Don't Cover (NZ)

2. Rain entering through roofs, windows and doors

Check the exclusions for water ingress, storm damage and defective or damaged building components. Some policies distinguish rain entering after storm damage from water entering because of poor maintenance, pre-existing defects or an opening left exposed during renovations.

3. Definition of contents and settlement basis

Confirm that the policy covers the affected belongings, including furniture, rugs, electronics, appliances, clothing and other personal possessions. Check whether claims are settled on a replacement-value or indemnity basis, and whether special limits apply to valuables or particular item categories.

Why it matters: coverage for the home itself does not automatically mean all damaged belongings are covered under the same policy. HouseholdersHome and contents insurance: How to make a claim

4. Gradual damage, mould, mildew and rot

Read the exclusions for gradual deterioration and any exception for hidden leaks. Sudden flood damage may be covered while mould or rot that develops over time may be excluded or subject to a separate limit.

Why it matters: secondary damage can be treated differently from the initial water damage. HouseholdersContents Insurance PolicyLimited Contents Insurance Policy

5. Additional benefits and temporary accommodation

Check whether the policy contributes towards removing, storing, cleaning or restoring belongings, and whether temporary accommodation is included. These benefits may have separate dollar limits, time limits or eligibility conditions.

Why it matters: the cost of recovering from a flood can extend well beyond replacing damaged possessions. Contents Insurance PolicyDistinction Contents Insurance / Policy wordingHome and contents insurance: How to make a claim

6. Excesses, exclusions and claim conditions

Check the applicable excess, per-item limits, total sum insured, duties to prevent further damage, and requirements to notify the insurer and document losses. Also check any waiting period or restrictions relating to newly purchased cover.

Why it matters: an otherwise covered event may still result in a reduced payment or a disputed claim. What Home, Contents & Car Insurance Don't Cover (NZ)Home and contents insurance: How to make a claimLimited Contents Insurance Policy

What to do if water has already entered your home

• Prioritise safety. Keep away from floodwater near electrical equipment, and leave if the property is unsafe.
• Notify your insurer promptly and ask what emergency drying, cleaning and removal costs it will authorise.
• Document the damage. Photograph or video the water level, the route the water took, and each affected item before disposing of anything, if safe to do so.
• Prevent further damage where safe. Keep receipts for reasonable emergency expenses, and avoid permanent repairs or discarding damaged belongings before discussing them with your insurer, unless urgent action is necessary for safety.
• Keep the building and contents claims distinct. If you own the property, damage to fixed structures will generally be considered under home insurance, while movable belongings are considered under contents insurance. If you rent, your own contents policy is particularly important.
