Storm Damage Insurance NZ 2026: What Car, House, and Contents Policies Cover & How to Claim
Cyclone Vaianu is expected to make landfall on the North Island on Sunday 12 April 2026, bringing damaging winds, heavy rain, and coastal inundation across much of the upper and central North Island. MetService has described it as a multi-hazard, potentially life-threatening event and the entire North Island is under a strong wind watch.
With upwards of 200mm of rain forecast in some areas within 18 to 24 hours, flooding, slips, fallen trees, and property damage are real possibilities. Now is the time to understand exactly what your insurance policies cover and what they do not.
This guide explains how storm damage is treated under your car, house, and contents insurance in New Zealand, what is typically excluded, and what steps to take if you need to make a claim.

This article provides general information only and does not constitute legal or financial advice. Insurance policies vary between providers. Always refer to your own policy document for full details of cover.
Step 1. House Insurance and Storm Damage
What Your Home Insurance Covers
Most New Zealand home insurance policies cover sudden and unforeseen damage caused by storms, flooding, and severe weather events. This typically includes:
Roof damage from high winds or fallen trees.
Structural damage from floodwater.
Demolition, site clearance, and rebuilding costs.
Temporary accommodation while your home is uninhabitable.
How Natural Hazards Cover Works
If your home insurance policy includes fire insurance (and most do), you automatically have natural hazards cover through the Natural Hazards Commission (NHC) Toka Tu Ake. This cover is funded by a levy included in your premium. Your insurer manages the entire claims process on NHC's behalf, so you only need one point of contact.
There is an important distinction to understand:
Storm or flood damage to your home is covered by your private insurer.
Storm or flood damage to your land (for example, silt removal, land scour, damaged driveways) may be partly covered by NHC, up to certain limits.
Landslide damage to both your home and land is covered by NHC, though claims may be declined if the damage is found to be caused by poor property maintenance such as blocked drains or inadequate retaining walls.
The NHC building cover cap is currently $300,000 plus GST per natural hazard event. Any costs above this cap are covered by your private home insurance policy, up to your sum insured. This is why having adequate home insurance cover is critical.
What Home Insurance Typically Does Not Cover
Gradual damage or poor maintenance: If your roof was already leaking before the storm, damage caused by that pre-existing issue is unlikely to be covered. Insurers cover sudden events, not wear and tear.
Uninsured properties: If you do not hold an active home insurance policy, you will not have natural hazards cover either.
Consequential losses: such as theft or vandalism after the event may not be covered under your home policy.
Step 2. Contents Insurance and Storm Damage
What Contents Insurance Covers
Contents insurance protects your personal belongings inside your home against sudden and unforeseen damage, including storm and flood damage. This typically includes:
Furniture, appliances, and electronics damaged by floodwater.
Clothing and soft furnishings ruined by water or mould following a flood.
Spoiled food if a power outage caused by the storm affects your fridge or freezer.
Contents insurance is equally important for renters. If you rent, your landlord's home insurance covers the building itself, but it does not cover your personal belongings. Without contents insurance, you would need to replace everything out of your own pocket.
Keep Your Sum Insured Up to Date
Many Kiwis underestimate the value of their household contents. A typical family's belongings can be worth $50,000 to $150,000 when you account for furniture, clothing, electronics, and appliances. If your sum insured is too low, you may not receive enough to replace what you have lost. It is worth reviewing your contents sum insured before a storm hits.
Step 3. Car Insurance and Storm Damage
Comprehensive Cover Is What You Need
Storm damage to your vehicle is not covered under home or contents insurance. To be protected, you need comprehensive car insurance.
Comprehensive car insurance typically covers storm-related damage including:
Floodwater damage to the engine, electrical system, and interior.
Dents and panel damage from hail or flying debris.
Damage from fallen trees or branches.
Windscreen damage.
Towing and storage costs if your vehicle is undriveable.
Third party fire and theft (TPFT) and third party only policies do not cover storm damage to your own vehicle. If you currently hold one of these policies, any repairs or replacement costs following storm damage would come out of your own pocket.
For a full breakdown of the three levels of car insurance cover, see Comprehensive vs Third Party Fire & Theft vs Third Party (Full NZ Breakdown).
Do Not Drive Through Floodwater
This is critical. If your car is damaged because you drove into floodwater, your insurer may decline your claim on the basis of reckless behaviour. New Zealand insurers have been clear on this point: damage resulting from deliberately driving into floodwater is not typically covered.
If your car has been submerged or water has entered the vehicle, do not attempt to start the engine. Doing so can cause further damage to the engine and electrical system, and airbags may deploy without warning. Contact your insurer to arrange a tow and inspection instead.
What Kiwis Are Paying for Car Insurance
The average cost of comprehensive car insurance in New Zealand is $1,298 per year ($108 per month) as of Q4 2025, based on Quashed Index data. Auckland drivers pay more, averaging $1,510 per year.
Kiwis who compared their car insurance through Quashed found a cheaper policy 80% of the time, with average savings of $367 per year. Run a free Quashed Market Scan to see how your premium compares.
Step 4. How to Make a Storm Damage Claim
Document Everything Before You Clean Up
After a storm, it is natural to want to start cleaning up immediately. However, documenting the damage first is essential for your claim. Take photos and videos of all damage to your home, contents, and vehicle before moving or disposing of anything.
Steps to Follow
Ensure everyone is safe: Your safety comes first. If your home is structurally unsafe, do not enter. Call emergency services if needed.
Photograph and video all damage: Capture the full extent of damage to your property, contents, and vehicle. Include close-ups and wide shots.
Contact your insurer as soon as possible: Your private insurer is your single point of contact for all storm-related claims, including the natural hazards portion. You do not need to contact NHC directly.
Prevent further damage: Take reasonable steps to protect your property from additional damage, such as covering a broken window or tarping a damaged roof. Keep receipts for any emergency repairs as these costs are generally claimable.
Keep receipts and records: If you dispose of damaged items like soft furnishings or spoiled food, photograph them and note what they were before disposal.
Step 5. Your Storm Insurance Checklist
With Cyclone Vaianu forecast to bring damaging winds and heavy rain to the North Island from Saturday night, now is the time to act.
Check Your Cover
Confirm your policies are active: Check your home, contents, and car insurance policies are current and paid up. If a policy has lapsed, you will not be covered.
Review your sums insured: Ensure your home and contents sums insured reflect current replacement values. Underinsurance is one of the most common issues after a major weather event.
Know your excess: Understand how much you will need to pay out of pocket if you make a claim.
Save your insurer's claims number: In a storm, phone lines can be busy. Having your insurer's contact details and policy number ready will save time.
Make an Emergency Plan
If you do not already have a household emergency plan, Get Ready (getready.govt.nz) walks you through how to build one. Make sure you have enough supplies to get through at least three days without power or water, and that everyone in your household knows what to do before, during, and after severe weather.
The National Emergency Management Agency (NEMA) is coordinating the national response to Cyclone Vaianu. Find your local Civil Defence Emergency Management Group, get official updates, and access guidance on evacuation planning through their site.
Prepare for Flooding
Flooding is one of the biggest risks from cyclones, especially when the ground is already saturated from recent rain. Get Ready: Floods from getready.govt.nz covers how to prepare your property, when to self-evacuate, and how to keep your household safe during and after a flood event, including dealing with contaminated water and cleaning up.
To protect your property ahead of the storm:
Secure outdoor items such as trampolines, outdoor furniture, and rubbish bins.
Clear drains and gutters of leaves and debris.
If you are in a flood-prone area, move valuables and appliances off the floor.
Park vehicles undercover or away from large trees; if flooding is likely, move them to higher ground.
Unplug small appliances to prevent power surge damage.
