Our shower has been leaking behind the wall for months without us knowing. Would house insurance normally cover the repair?

In New Zealand, it depends on what caused the leak and what your policy says, but a shower that has been leaking behind a wall for months is often treated as gradual damage, which is commonly excluded from standard house insurance. ICNZ | Insurance Council of New Zealand

The key questions are:

  • Where was the water coming from?

    • If it was a hidden internal pipe (for example, a pipe inside the wall) that failed without you knowing, some policies may cover the resulting hidden water damage, often with a dollar limit. ICNZ | Insurance Council of New Zealand
    • If it was the shower seal, shower tray/base, grout, silicone, waterproofing failure, or a poorly maintained shower area, insurers commonly consider that gradual deterioration or maintenance-related damage and may decline it. Tower Insurance NZ

  • What part of the repair are you claiming for?

    • Many policies may cover some damage caused by a hidden leak (such as damaged wall linings or flooring) if the conditions are met.
    • They often do not cover fixing the thing that caused the leak (for example, replacing failed seals or repairing the shower itself). Aon

Given you only discovered it after months, I’d suggest:

  1. Don’t start major repairs before contacting your insurer (except urgent steps to stop further damage).
  2. Take photos/videos of the damage and any visible signs.
  3. Get a plumber or builder to identify and document the source of the leak.
  4. Lodge a claim and let the insurer assess it—even if you’re unsure whether it will be accepted.

If you tell me:

  • whether the leak was from the shower plumbing inside the wall or from the shower lining/seals/base, and
  • which insurer you’re with (if you’re comfortable sharing),

I can give a more specific idea of how it is likely to be treated.

Our shower has been leaking behind the wall for months without us knowing. Would house insurance normally cover the repair?

Whether your house insurance will cover a hidden shower leak depends heavily on the exact wording of your policy, how the leak originated, and the definition of gradual damage.

Because the leak happened slowly over months, it falls into a grey area for insurers, but many standard comprehensive policies in New Zealand do offer some level of relief.

1. The "Gradual Damage" Exclusions vs. Hidden Leak Benefits

Standard house insurance is designed for sudden, accidental, and unforeseen events (like a pipe instantly bursting). Damage that occurs slowly over time—such as rot, mildew, or warping from a slow leak—is typically classed as gradual damage and is excluded by default.

However, many major New Zealand insurers include a specific "Hidden Gradual Damage" or "Hidden Water Damage" benefit in their comprehensive policies.

2. What Is Typically Covered (and What Isn't)

If your policy includes a hidden gradual damage clause, it usually operates under specific conditions:

  • The Rot/Structure Damage: Insurers will often provide a limited contribution (frequently capped between $2,000 and $5,000, depending on your provider and tier of cover) toward repairing the structural damage caused by the hidden moisture, such as rotted framing or ruined linings behind the wall.
  • The Cost to Fix the Leak Itself: Most policies will not pay to fix the actual source of the leak (e.g., they won't pay a plumber to re-seal the shower waste, fix a cracked acrylic liner, or repair a faulty pipe joint). You are generally responsible for the cost of stopping the leak.
  • The "Hidden" Requirement: The leak must genuinely have been hidden from view. If there were obvious warning signs earlier (like peeling paint, a spongy floor outside the shower, or a musty smell that was ignored for months), an insurer may argue the damage wasn't truly hidden or that you failed to mitigate it.

Next Steps

  1. Check your policy wording: Look for sections covering "Gradual Damage," "Hidden Water Damage," or "Leaking Pipes."
  2. Find and fix the source: Document everything with photos before a plumber fixes it, and get a professional opinion on how long it likely leaked and why.
  3. Talk to your insurer: Call your provider, outline that it was a hidden internal leak behind a wall, and ask if your policy includes a hidden gradual damage sub-limit.

Our shower has been leaking behind the wall for months without us knowing. Would house insurance normally cover the repair?

AI Overview

In New Zealand , standard house insurance will not normally cover the full cost to repair this type of damage because it is classified as gradual damage rather than a sudden, accidental event.

However, you will likely be eligible for partial coverage under a specific policy extension called Hidden Gradual Water Damage. How this works depends on what exactly caused the leak and your specific policy limits.

1. The Resulting Damage May Be Partially Covered

Most comprehensive New Zealand home insurance policies (such as those from AA Insurance, AMI, State, or Tower) include a Hidden Gradual Damage benefit. If you couldn't have reasonably known about the leak because it was hidden inside the wall, your insurer will typically contribute toward fixing the resulting damage (like rotted timber framing, damp wall linings, or mold).

  • The Catch: This benefit is strictly capped. In New Zealand, the limit is typically between $1,500 and $5,000 depending on your provider and policy tier. Your standard policy excess will also be deducted from this amount.

2. The Source of the Leak Matters

To qualify for the hidden gradual damage extension, the water must usually come from an internal water supply pipe, waste pipe, or internal tank.

  • ❌ What is excluded: If the leak was caused by a failed waterproofing membrane, a deteriorating silicone seal around the shower tray, or cracked grouting, it is often completely excluded. Insurers view maintaining these seals as standard home maintenance.

3. You Must Pay to Fix the Plumbing Asset Itself

Even if your claim is accepted under the hidden gradual damage extension, insurance never covers the cost of fixing the actual pipe or plumbing fixture that failed. You will have to pay the plumber out of pocket to repair the source of the leak, while the insurance payout goes toward rebuilding the wall and floor.

📋 Recommended Next Steps

  1. Call a plumber immediately: Do not delay, as insurance companies can decline claims if they believe you let the damage get worse after discovering it.

  2. Ask for a written report: Have the plumber explicitly state in their invoice what caused the leak (e.g., a pinhole leak in a copper pipe vs. a failed shower seal) and whether it was visible.

  3. Take photos: Take extensive photographs of the wall cavity, rotted framing, and the plumbing issue before any repairs begin.

  4. Contact your insurer: File a claim under your Hidden Gradual Damage extension using the plumber's report as supporting evidence.

To help guide you further, do you happen to know who your insurance provider is or what exactly caused the leak (e.g., a burst internal pipe or a worn-out silicone seal)?

Our shower has been leaking behind the wall for months without us knowing. Would house insurance normally cover the repair?

In New Zealand , house insurance policies generally do not fully cover damage that occurs slowly over a long period (known as gradual damage), because maintenance is considered a homeowner's responsibility.

However, many New Zealand insurers include a specific Hidden Gradual Damage extension or benefit (often capped between $1,000 and $5,000, depending on your provider and policy) that may provide a limited contribution.

Key factors that determine if you have any cover include:

  • The source of the leak: Hidden gradual damage extensions usually only apply if the leak came from an internal water pipe, waste pipe, or water tank hidden behind the wall. If the leak was caused by worn-out tile grout, a failed shower membrane, or a deteriorated silicone seal, insurers often classify that as lack of maintenance rather than a leaking pipe, meaning it may be entirely declined.

  • Was it truly hidden? The damage must have been undetectable and unable to be seen through normal observation or regular home maintenance.

  • Cost of the fix vs. the damage: Even if a policy’s hidden gradual damage benefit applies, it typically covers the resulting structural damage (like rotted framing) up to the sub-limit, but it does not cover the cost of repairing the actual plumbing failure or the worn shower seal itself. [Initio Insurance NZ]

  • Your policy excess: The standard policy excess will still apply and is usually deducted from any payout. [Initio Insurance NZ]

To see where you stand, check your specific policy wording for terms like "hidden gradual water damage" , "water leakage" , or "gradual deterioration". [AA Insurance]

If you'd like to share:

  • The exact source of the leak (e.g., a burst internal pipe vs. leaking grout/sealant)
  • The name of your insurance provider

I can give you a better idea of how they typically handle hidden leaks.
