Careless damage and the four weeks' rent cap

How the cap actually works

The rule reads simply enough. If a tenant or their guest causes careless damage to a rental property, the tenant is liable for the cost of that damage up to four weeks' rent, or the landlord's insurance excess, whichever is lower.

The word doing the work is lower. Two numbers are compared, and the smaller one wins. Say the rent is $600 a week, so four weeks is $2,400. If the landlord's excess is $1,000, your ceiling is $1,000 — not $2,400, and not the $4,000 the repair might actually cost. If instead the excess were $3,500, your ceiling would be $2,400, because that is now the lower figure.

Everything above the ceiling is the landlord's problem, which is precisely what their insurance is there for.

Why your landlord's excess is your business

Once you understand that the excess can set your maximum liability, it stops being a private detail of somebody else's policy and becomes a number that directly determines what you might owe. The law reflects that. A landlord must state in any new tenancy agreement whether the property is insured and the excess amount of any relevant policy, and must include a statement telling you the policy is available on request. If that information changes, they have to tell you within a reasonable time.

If it is not in your agreement, you are entitled to ask. It is not a cheeky question.

Careless, deliberate, or neither

Almost every genuine dispute in this area is really an argument about which of three boxes something falls into.

Fair wear and tear

The ordinary deterioration of a property through normal living. Carpet flattening along a hallway, scuff marks at door height, a tap washer going. Tenancy law treats this as something other than damage — the pet bond rules, for instance, are framed around pet-related damage that is more than fair wear and tear. Where something is genuinely wear and tear, the liability cap does not come into it, because the argument is about the category rather than the amount.

Careless damage

Damage you did not mean to cause. The red wine on the carpet. The pot left on the element. The washing machine hose that was not pushed on properly. This is where the four weeks' rent or excess cap does its work.

Deliberate damage

Damage done on purpose, or damage resulting from an act that is an offence. The cap does not protect you here, and a landlord's own cover for it is usually limited too — Tower, for instance, publishes a separate sub-limit of up to $20,000 for deliberate damage by tenants or their guests on its Landlord's Plus policy, rather than covering it up to the sum insured. Meth contamination caused by a tenant sits in this territory as well.

Where insurance comes into it

The cap limits what you owe. It does not pay it for you. That is what the personal liability section of a contents policy is for, and it is the single strongest argument for a renter holding contents cover even if their possessions are modest.

AA Insurance sets this out on its own renters page using the carpet-staining example directly: where the landlord makes an insurance claim, AA covers the difference between the landlord's excess and the renter's own contents excess. That is the insurer's own published description of how the cover responds. Every insurer words this differently and the policy wording is what governs, so this is a question worth asking specifically rather than assuming your policy behaves the same way.

If you are already in a dispute

The rules above are the framework, not a prediction of the outcome. Whether a particular mark is wear and tear or damage, whether damage was careless or deliberate, and what the repair reasonably costs are all matters of fact that can be argued. The Tenancy Tribunal exists to decide them, and Tenancy Services publishes guidance on getting there.

If a claim is being made against you and you hold contents insurance, tell your insurer early rather than after you have agreed to pay something. Liability cover generally comes with conditions about admitting liability, and settling first can cause problems.
