What invalidates landlord insurance?

Rather than one dramatic act, it is usually a failure to meet an obligation the policy already imposes. Vero publishes that many landlord covers include specific obligations you must meet to keep the insurance valid — selecting tenants carefully, actively monitoring rent payments, and making regular property checks. Initio publishes that claiming under its landlord protection benefits requires you to be meeting your landlord obligations under the policy.

Do I have to tell my insurer the property is rented out?

Yes, and this is the most common failure. Vero states that when you take out a policy you need to specify to your insurer that the property is tenanted rather than owner-occupied, and to check whether that brings special conditions or excesses. An owner-occupier policy on a tenanted house is a problem waiting to surface at claim time.

Can my insurer decline a claim because I did not screen the tenant?

Tenancy Services notes that some insurers require the landlord to prove thorough tenant checks were done before they will accept a claim, and Vero lists selecting tenants carefully among the obligations that keep cover valid. If you self-manage, your screening file is part of your insurance.

How often do I need to inspect the property?

Policies vary and you should read yours. The reason insurers ask is published plainly by Vero: regular checks help identify problems quickly and prevent them getting worse. Inspections also have their own notice requirements under the Residential Tenancies Act, and inspection reports are among the documents landlords must keep during a tenancy and for 12 months after.

Does leaving the property empty affect my cover?

Check your wording, because unoccupancy provisions do exist. Tower publishes one on its renters contents policy: if the home is unoccupied for more than 90 consecutive days, cover is limited from day 91. We have not verified an equivalent clause on every landlord product, so treat this as a question to ask rather than a rule — particularly before a long vacancy or a renovation.

Why does a series of small stains cost me more than one big one?

Because each "event" of damage carries its own excess. Vero explains this on its own site: several separate stains over months would probably incur a higher total excess than the claim is worth, unless you can prove they resulted from a single incident. It is one reason infrequent inspections cost landlords money — damage accumulating unseen feels like one event but is not.

If you let

What actually invalidates landlord cover

Rarely one dramatic act. Almost always a condition in the policy that was never read — and most of them are about how you run the tenancy, not how you maintain the building.

The short version

Declare that the property is tenanted, not owner-occupied. Vero says to check what conditions or excesses that brings.
Vero publishes the obligations that commonly keep cover valid: select tenants carefully, actively monitor rent payments, make regular property checks.
Initio publishes that claiming under its landlord protection benefits requires you to be meeting your landlord obligations.
Tenancy Services notes some insurers require proof of thorough tenant checks before accepting a claim.
Each “event” of damage carries its own excess — several small ones can cost more in excesses than the claim is worth.
Keep the paperwork: inspection reports and correspondence must be retained during the tenancy and for 12 months after.

The one that catches most people

Not telling the insurer the house is rented out.

Vero puts it directly: when you take out a policy you need to specify to your insurer that the property is tenanted rather than owner-occupied, and check whether that means special conditions or excesses apply. People move out, rent the house, and leave the existing policy running because it is still “their” house. The risk the insurer priced is no longer the risk they are carrying, and that is exactly the sort of thing that gets examined when a claim is large.

The obligations that sit inside the policy

Landlord covers routinely impose conduct obligations on the landlord — not maintenance obligations about the roof, but obligations about how you run the tenancy. Vero publishes the three that recur:

Selecting your tenants carefully.
Actively monitoring rent payments.
Making regular checks of your property, so problems are found early and do not get worse.

Initio frames the same principle as a claims condition: to claim under its landlord protection benefits, you must be meeting your landlord obligations under the policy. And Tenancy Services separately notes that some insurers require the landlord to prove thorough tenant checks were done before they will accept a claim.

Read together, these say something practical: your tenant screening file, your rent ledger and your inspection reports are not admin. They are the evidence that your cover still works.

The excess trap Vero explains better than anyone

This one is worth understanding because it quietly costs landlords real money.

Each event of damage carries its own excess. Vero's own example: multiple stains on a floor accumulated over many months, which you discover all at once and which together make you want to replace the carpet. It feels like a single claim. It is not — and the combined excesses would probably exceed what the claim is worth, unless you can prove the stains resulted from one incident.

Vero also names why this bites landlords specifically: an owner-occupier watches damage accumulate, but a landlord inspecting infrequently sees the total for the first time and experiences it as one event. More frequent inspections are not just an insurer's box-tick; they are what lets you treat damage as the discrete events it actually is.

Deliberate damage, and where the wall is

Vero states its general position plainly: insurance policies are designed to cover accidental damage, so deliberate damage by a tenant generally will not be covered under a standard policy. Landlord products then buy back a limited amount of it — Vero's optional landlord extension covers malicious damage by tenants up to $30,000; Tower publishes up to $20,000 for deliberate damage on Landlord's Plus; Initio publishes up to $25,000 per event for intentional damage, vandalism or theft, with serious fire or explosion damage extending above that limit to the full sum insured.

Those are three insurers' own published summaries, retrieved 8 September 2026, and they are deliberately not tabulated — an optional extension, a built-in benefit and a per-event limit are not the same shape of thing. Wordings govern.

Recovering your excess is your job, not the insurer's

Vero is unusually direct about this, and it connects straight to your disclosure duties. If tenants accidentally damage the property you may be able to recover your excess from them — but you will need to have told them what your excess is and given them a copy of your policy. And claiming it back is handled between you and the tenant: your insurer will not be able to get involved.

Which is the practical case for treating the tenancy agreement disclosure as a live document rather than a formality. The disclosure duty is here, and the cap on what you can recover is here.

A short checklist

Is the policy actually a landlord policy, and does the insurer know it is tenanted?
Do you have a screening file for the current tenants?
Are you monitoring rent, and can you show it?
Are inspections happening, and are the reports kept?
Do the tenants have your excess figure in writing, and a copy of the policy on request?
What does the policy say about unoccupancy, and does your vacancy plan breach it?

Where this comes from

Landlord obligations, the tenanted-property declaration, the per-event excess point and the excess-recovery position are from Vero. The claims condition and limits are from Initio and Tower, all retrieved 8 September 2026. The tenant-screening note and record-keeping duty are from Tenancy Services (MBIE). Policy wordings govern.
