Most house policies cover small alterations up to a set limit, and bigger work needs the insurer told first.

The short answer
Most house policies cover small alterations up to a set limit, and bigger work needs the insurer told first.
House policies usually include a small amount of cover while minor work is under way. The limit is low and it differs a lot between insurers.

Ratings are curated from a number of sources, including Google, Feefo and Trustpilot. They may not be completely up to date. They measure what reviewers said about dealing with a company, which is not the same thing as what its policy covers, and a brand shown as not rated is one we hold no reviews for rather than one that scored badly.
Highly rated rows appear first and are marked. Every other brand is listed alphabetically. Nothing in this table is ordered by how good the cover is, and no figure here is our assessment of any insurer.
In more detail
Larger work is a different thing. Once a job is big enough, the builder or the owner normally needs a contract works policy, which covers the building work itself.
Telling your insurer before the work starts is what keeps your cover intact. A fuller guide is being written.
Disclaimer
Home insurance is one of the few contracts most households hold for decades and read once. What a policy covers, what it excludes, and what has to be disclosed before it starts all vary between insurers and between versions of the same product, and the wording is what settles a claim. This site explains how the cover generally works so those conversations start from a better place. It is not a substitute for the policy document.
What this site is
An information site about insuring a home in New Zealand. Not an insurer, not a broker, not a registered financial adviser. Nothing here is personalised financial advice or a recommendation about any particular property.
What this site does not do
It publishes no premiums, no rebuild costs and no sum-insured figures, and nothing here estimates one. Those numbers come from an insurer's own calculator or a registered valuer, and getting them wrong is what underinsurance is made of.
What the insurer decides
Whether cover is offered, on what terms, at what price and with what exclusions is decided by the insurer, on the information given to them about the specific property.
Our relationship with Cove
This site refers people to three insurance brands. Cove for most homes, FMG for farms and lifestyle blocks, and AA Insurance for apartments. We receive no commission, fee or payment for any of those referrals, and nothing on this site is sold. No brand can buy a position, a badge or a mention. We are not an insurer, not a broker, and not a registered financial adviser. Nothing here is a recommendation that any brand is right for any particular home. Full disclosure on the partner page.
The policy wording decides
Every description of cover on this site describes what that type of cover generally does, not what any particular policy does. Limits, excesses, exclusions and conditions differ between insurers and change between versions, and the wording issued with a policy is the document that settles a claim.
