Will house insurance cover a leak that's been getting worse for months? Do NZ insurers differ on this?

In New Zealand, a house insurance claim for a leak that has been getting worse over months is often difficult, but it depends on what caused the leak, whether it was hidden, and your insurer’s policy wording. NZ insurers do differ. AMP

The key distinction is usually:

  • Sudden and accidental damage (for example, a pipe suddenly bursts and floods part of the house) is commonly covered.
  • Gradual damage (for example, a slow leak that has been occurring for months, causing rot, mould, or deterioration) is commonly excluded unless the policy has a specific gradual/hidden damage benefit. AMP

A few examples:

  • Hidden leaking pipe inside a wall: Some NZ policies cover the resulting damage (such as damaged walls or floors), often with limits, but may not cover fixing the pipe itself. AMI Site
  • Leaking shower, failed sealant, roof leak, or maintenance issue: These are more likely to be treated as gradual damage, wear and tear, or lack of maintenance and may not be covered. AMP
  • You noticed the leak getting worse but did nothing: An insurer may argue you had a duty to minimise further damage, which can affect the claim outcome. Some policies expressly require you to take reasonable steps once damage is discovered. Home

Do NZ insurers differ?

Yes. Differences commonly include:

  • Whether they offer hidden gradual damage cover automatically or as an option.
  • The maximum amount they will pay (some policies have relatively low sub-limits).
  • What counts as a qualifying leak (for example, an internal water pipe versus a shower or roof).
  • Whether they cover costs to locate the leak, and under what circumstances. AMI Site

Examples of different approaches:

  • AMI Insurance policies include a hidden gradual damage benefit for certain hidden internal pipe leaks, subject to conditions and limits. AMI Site
  • NZI policies describe cover for hidden gradual damage discovered during the period of insurance, with limits and conditions. NZI Site
  • Tower Insurance also provides hidden gradual water damage cover in some policies, with limits and exclusions. Tower Insurance NZ

If you have a leak now, practical steps are:

  1. Stop or reduce the source of the leak if you safely can.
  2. Take photos/videos before repairs.
  3. Notify your insurer promptly (even if you are unsure whether it will be covered).
  4. Do not remove damaged materials unnecessarily unless needed to prevent further damage, and keep evidence.

If you tell me where the leak is coming from (roof, shower, pipe in wall, bathroom, window, etc.), how long you knew about it, and which insurer/policy you have, I can help you assess how it is likely to be treated.

Will house insurance cover a leak that's been getting worse for months? Do NZ insurers differ on this?

In New Zealand, house insurance policies are fundamentally designed to cover sudden, accidental, and unforeseen events (like a sudden pipe burst or storm damage). Because a leak that has been getting worse for months has occurred slowly over time, it generally falls under the category of gradual damage, which is a standard exclusion in NZ house insurance policies.

However, whether you get any payout depends heavily on specific policy provisions and how the leak happened.


Do NZ insurers differ on this?

Yes, NZ insurers do differ, specifically regarding "Gradual Damage Extensions" (or hidden water damage benefits).

While almost all mainstream insurers will exclude standard gradual damage if a leak is left unaddressed, many offer a limited sub-limit or extension for hidden internal water leaks.

  • The Catch with Extensions: If your policy includes a hidden water damage benefit, it usually comes with strict conditions:
    • The leak must be from an internal pipe, water reticulation system, waste disposal unit, or water tank (leaks originating from external sources, weather ingress through roofs, or waterproofing failures in showers/balconies are often completely excluded).
    • The damage must have been truly hidden (i.e., located inside a wall or under a floor where you could not reasonably have known about it immediately). If it has been getting progressively worse and visible signs (like rotting, discolouration, or peeling paint) were ignored for months, insurers may argue you failed to take reasonable care or maintain the property.
    • Capped payouts: Unlike standard claims that cover the full cost to rebuild, insurer extensions for hidden leaks are usually capped—typically ranging anywhere from $2,000 to $5,000 depending on the provider and your specific tier of cover.
  • The Cost of Fixing the Leak vs. Resultant Damage: Standard insurance generally never covers the cost of fixing the leak itself or the pipe that caused it (that is maintenance). If an extension applies, it typically contributes toward the resultant damage (like ruined linings or structural framing caused by the water), and you will still have to pay your policy excess.

What should you do next?

  1. Check your policy wording: Look specifically for sections covering "Gradual Damage," "Hidden Water Leaks," or "Limited Water Damage Extension."
  2. Get a professional opinion: Insurers will usually require a report from a plumber or builder to determine the exact origin of the leak and how long it has been active.
  3. Talk to your insurer: Notify them as soon as possible. Delaying notification further can compromise any limited benefit you might otherwise have been entitled to under a hidden leak extension.

Will house insurance cover a leak that's been getting worse for months? Do NZ insurers differ on this?

AI Overview

Yes, but only partially, and only if the leak was completely hidden. Standard New Zealand house insurance policies do not provide full coverage for leaks that develop over months, as insurance is designed for "sudden and accidental" events.

However, most NZ insurers offer a specific policy extension called "Hidden Gradual Water Damage". This benefit provides a capped, limited payout to repair the resulting rot or mildew, provided the leak met strict criteria.


Critical Conditions for Coverage

To qualify for a hidden gradual damage claim, the situation must meet the following rules:

  • It must be genuinely hidden: The leak must be completely out of sight (e.g., inside a wall cavity, under floorboards, or in the ceiling). If the leak was visible—such as a dripping tap, a visibly molding wall, or a pooling shower tray—and it was ignored, the claim will be declined due to a lack of maintenance.

  • The source matters: The leak must originate from an internal plumbing system, waste pipe, hot water cylinder, or internal water tank. Leaks coming from roof degradation, blocked gutters, or worn-out silicone seals around a shower or bath are generally excluded entirely.

  • It does not fix the leak itself: Insurance only pays for the resultant damage (e.g., replacing the rotted framing or ruined drywall). The homeowner must pay out-of-pocket for the plumber to fix the actual broken pipe.


How New Zealand Insurers Differ

While most major insurance companies offer this extension, they differ significantly on the maximum payout limit. The policy excess is deducted directly from these sub-limits.

Insurer / Policy Gradual Damage Cap Notes / Exclusions
AMP Insurance Up to $5,000 High limit; excludes landlord policies which cap at $2,500.
AA Insurance Up to $5,000 Specifically excludes leaks from shower bases or recesses.
MAS (Medical Assurance Society) Up to $5,000 Comprehensive policy sub-limit.
State Insurance Up to $3,000 Per year cap for internal plumbing leaks.
AMI Insurance Up to $3,000 Standard policy limit (Note: some older or legacy AMI wording may restrict this to $1,500)
initio Insurance Up to $3,000 Standard house insurance cap.
Tower Insurance $1,000 to $3,000 Tiered: Standard ($1,000), Plus ($2,000), Premium ($3,000).

Because hidden water damage can easily cost tens of thousands of dollars to fully remediate, a $1,000 to $5,000 cap means the homeowner often has to fund the remainder of the rebuild costs personally.

If you are dealing with a live leak, it is best to capture clear photographic evidence before any emergency repair work begins, and contact your insurer or broker immediately to establish the timeline of the damage.

To help narrow down whether your leak might be covered, could you tell me:

  • Is the leak currently visible , or is it hidden behind a wall or under the floor?

  • Do you know the exact source (e.g., a pipe, the roof, or a shower tray)?

  • Who is your current insurance provider?

Will house insurance cover a leak that's been getting worse for months? Do NZ insurers differ on this?

In New Zealand , standard house insurance is designed to cover sudden, accidental, and unforeseen events (like a pipe bursting abruptly). A leak that has been getting worse over months is generally classified as gradual damage (wear and tear, slow corrosion, rotting, or mildew), which is excluded from standard policies.

However, whether you get any payout depends heavily on the specific nature of the damage and how your particular insurer structures their policy.

Core Principles Across NZ Insurers

  • The Leak Itself vs. Resultant Damage: No New Zealand insurer will pay to fix the actual source of the gradual leak or replace the deteriorated pipe/fitting itself.

  • The "Gradual" Rule: If you knew about the leak and did nothing, or if it occurred openly over a long period, it is entirely uncovered. [Insurance Council of New Zealand (ICNZ)]

  • Resultant Damage Caveat: Sometimes, if a sudden event causes subsequent damage, or if minor consequential damage applies, there can be grey areas. But a leak worsening over months firmly sits in the gradual exclusion zone.

Do NZ Insurers Differ?

Yes, insurers do differ , primarily through optional or built-in Gradual Damage Extensions (sometimes called hidden water leak cover): [Insurance Council of New Zealand (ICNZ)+1]

  • Limited Sub-limits for Hidden Leaks: Many major NZ insurers (such as AA Insurance, AMP, and others) offer a limited extension for hidden gradual damage—for example, a slow leak from an internal pipe sealed behind a wall or under a concrete floor that you genuinely could not have known about. [Insurance Council of New Zealand (ICNZ)+2]

  • The Catch on "Getting Worse for Months": These hidden leak extensions usually apply only if the damage was completely undetectable by normal inspection. If a leak has been visibly getting worse for months or is in an accessible area (like under a sink or an obvious ceiling stain you ignored), insurers will argue it was discoverable and fail the "hidden" criteria. [Insurance Council of New Zealand (ICNZ)+1]

  • Payout Caps: Where cover does exist for hidden gradual damage, it is almost always heavily capped—typically ranging from $2,000 to $10,000 depending on the tier of the policy—and it usually excludes the cost of opening up or repairing the wall/floor to find the leak itself. [Insurance Council of New Zealand (ICNZ)+1]

If you'd like, share:

  • Where the leak is located (e.g., hidden inside a wall vs. under a visible sink)
  • When and how you first noticed it
