After every big blow, the same sequence plays out across thousands of New Zealand homes. A few lifted sheets, a leak that was not there yesterday, a branch through the gutter, a stain spreading across a ceiling. The damage is the obvious part. What is far less obvious is how the insurance side actually works and the gap between what homeowners assume is covered and what is genuinely covered is where most of the stress, and most of the disappointment, lives.
This post walks the pathway from storm to settled claim, with particular attention to the parts that catch people out.
The line that decides everything: sudden versus gradual
Most New Zealand home policies cover sudden and unforeseen damage. A storm tearing sheets off, a tree coming down on the roof, wind-driven water forced in where it could not normally get: that is the kind of event insurance exists for. What policies do not cover is wear and tear, or gradual deterioration. This is the distinction that determines whether your claim is paid and it is worth being honest with yourself about before you lodge it.
In practice it means two very similar-looking situations get treated completely differently. A sound roof damaged by an exceptional storm is a claim. An old roof at the end of its life that finally failed during a storm is, in the insurer's eyes, often wear and tear that the weather merely exposed. If the roof was already leaking or visibly degraded before the event, the insurer can decline the part of the damage that flows from the pre-existing condition. The weather has to be the cause, not just the timing.
Who covers what
Storm damage to your roof and the rest of your building is covered by your private home insurer, assuming your policy includes fire cover, which almost all do. The Natural Hazards Commission, Toka Tū Ake, which replaced EQC, covers certain damage to the land under and around your home, such as silt and scour, not storm damage to your roof. You do not need to deal with two organisations: your insurer manages the whole claim and is your single point of contact. For a wind-damaged roof, this is squarely a private insurance matter.
Your first moves after the storm
Make it safe and weathertight, but do not start major repairs yet. Reasonable temporary steps to prevent further damage, such as tarping a damaged roof, are expected of you and the cost is generally claimable. Keep the receipts. Hold off on permanent repairs until the insurer has been in the loop, because work done before assessment can complicate the claim.
Document everything before you clear it. Photograph the damage from multiple angles before you move or dispose of anything. Note dates. If a ceiling is stained or contents are wet, capture that too. Evidence gathered in the first hour is worth more than a description given a week later.
Check the basics of your policy. Confirm the policy is current and paid, find your excess in the policy schedule and check your sum insured reflects what your home would actually cost to rebuild. Underinsurance is one of the most common problems after a major weather event.
Cash settlement versus managed repair and why it matters who picks the roofer
After assessing the damage and agreeing a scope of works, most weather-event claims in New Zealand are settled in cash. The insurer pays you a lump sum representing their estimate of the reasonable cost to repair the damage and you arrange the work. This is different from a managed repair, where the insurer runs the job using their own contractors. In a widespread event, insurers usually do not have the capacity to offer managed repairs, so cash settlement is the norm.
The practical consequence is important: a cash settlement means you choose the roofer. That is an advantage, because you control who goes on your roof and to what standard. It also carries a risk. The settlement is the insurer's estimate and if your actual repair cost on a like-for-like basis comes in higher, the shortfall can land on you. It is not automatic that the insurer tops it up. This is precisely why the quality of your scope and your quote matters so much. A properly written specification, quoted accurately, is what protects you from agreeing to a number that turns out to be short.
The excess and the sum-insured trap
Your excess is deducted from the settlement before you receive it. The figure that catches people out, though, is what happens to your cover afterward. Until the damage is actually repaired, your sum insured is reduced by the amount you have been paid. In plain terms, if another event hits before you have done the repairs, you are insured for less and the damaged area may not be covered at all. This is the reason not to sit on a cash settlement. The money is to fix the roof and your full cover is only restored once it is fixed.
If you disagree with the outcome
If your claim is declined or the settlement looks short, the first step is a direct conversation with your insurer about the reasons. If that does not resolve it, you can make a complaint, escalate to the insurance industry's free dispute resolution scheme, or take the matter to the Disputes Tribunal. As of January 2026 the Tribunal can hear claims up to 60,000 dollars, double its previous limit, which now covers a far larger share of roofing and building disputes. Lawyers cannot represent you at the hearing, the filing fee is modest and hearings are usually scheduled within weeks. An independent condition report can be valuable here as third-party evidence of what the damage actually is.
The claim in one sentence
Whether you are paid turns on the difference between sudden storm damage and an old roof at the end of its life and how much you are paid turns on the quality of the scope and quote behind your settlement.
