Living with flatmates in New Zealand often works well for months, then one unpaid power bill, a dirty kitchen, or a flatmate who stops talking to everyone flips the whole dynamic. Most people assume the rules that protect tenants also protect them, but the research says otherwise. A flatmate is not a tenant under the Residential Tenancies Act 1986, which means the Tenancy Tribunal cannot hear a dispute between flatmates. That single fact changes everything about how you handle a conflict, recover unpaid rent, or end a living arrangement. Here’s what you actually need to know.

Flatting is the most common housing arrangement for young renters in New Zealand, yet most people walk into a shared house without a written agreement and assume the law works the same way it does for a tenant. It doesn’t. The distinction between a tenant and a flatmate has real consequences for bond disputes, notice periods, and who you can take to a tribunal. And the person who stands to lose the most is often the head tenant, who is legally responsible for the entire property.
What Makes a Flatmate Different From a Tenant in NZ
The first thing to understand is the legal line that separates a tenant from a flatmate. A tenant signs a tenancy agreement with the landlord and has exclusive use of the rental property. That person is protected by the Residential Tenancies Act, which covers bond lodgement, notice periods, and access to the Tenancy Tribunal.
A flatmate, by contrast, shares the property with a head tenant and does not have a direct relationship with the landlord. The RTA does not apply to flatmates. If you are sharing a kitchen, bathroom, or living area with the person who signed the lease, you are almost certainly a flatmate, not a tenant. The only exception is if you have a self-contained space with exclusive access, in which case the RTA may apply.
What I tend to notice is that most people don’t realise this distinction until something goes wrong, and by then the wrong tribunal has been contacted and weeks have been wasted.
The Real Cost of a Flatmate Fallout
A flatmate dispute rarely stays small. What starts as a disagreement about cleaning duties can quickly turn into lost rent, a damaged bond, or a head tenant facing a landlord’s termination notice. The table below shows the typical financial risks.

| Situation | Who pays | How to recover |
|---|---|---|
| Flatmate stops paying rent | Head tenant must pay the landlord in full | Disputes Tribunal claim for unpaid rent |
| Flatmate damages property | Head tenant is liable to the landlord | Disputes Tribunal or written agreement on deductions |
| Flatmate leaves without notice | Remaining flatmates cover the rent | Reasonable notice period applies; claim through Disputes Tribunal |
| Bond dispute at move-out | Head tenant holds the bond (no legal lodgement required) | Disputes Tribunal if no written agreement |
There is a hidden cost that rarely gets mentioned. If a head tenant sublets without the landlord’s written consent, the landlord can terminate the entire tenancy. That means every flatmate in the house could be looking for a new place within weeks. The ShiftScript guide warns that unauthorised subletting is a breach of the tenancy agreement, and the consequences fall on the head tenant first.
Another figure worth weighing is the cost of lost rent. If a flatmate leaves without notice and the remaining flatmates cannot cover the shortfall, the head tenant is still on the hook to the landlord. The Disputes Tribunal can order the former flatmate to pay, but that takes time and an application fee. In the meantime, the head tenant’s credit or tenancy record may already be affected.
Where Flatmates Most Often Get It Wrong
No written agreement in place
This is the most common mistake and the one that causes the most damage. Without a written flatmate agreement, there is no record of the notice period, the bond amount, or who pays for what. When a dispute arises, each person has a different memory of what was agreed. The Tenancy Services flatting guide provides a free template, but most people skip it. What I’d do: fill out the template before the first flatmate moves in. It takes 15 minutes and saves months of uncertainty.
Assuming the Tenancy Tribunal can help
Flatmates often call the Tenancy Services helpline expecting to file a claim against each other. The Tenancy Tribunal only hears disputes between landlords and tenants. Disputes between flatmates are general civil disputes and must go to the Disputes Tribunal. The distinction matters because the Disputes Tribunal has a different application process and a lower monetary limit. If you have already applied to the wrong tribunal, you will have to start over.
Handling the bond like a landlord
Under the RTA, landlords must lodge bonds with MBIE within 23 working days. For flatmates, there is no legal requirement to lodge a bond at all. That sounds convenient, but it creates a real risk. If a flatmate pays a bond and the head tenant spends it, the flatmate has no automatic protection. The head tenant should hold the bond in a separate trust account and provide a written receipt. If the flatmate later claims tenant status, the head tenant could be liable for failing to lodge the bond. A written agreement stating the RTA does not apply is essential here.
Locking a flatmate out or removing their belongings
When a flatmate stops paying rent, the instinct is to change the locks or throw their stuff on the lawn. That is legally risky. Even without a written agreement, a flatmate has occupancy rights under common law. A head tenant who locks out a flatmate without proper notice can face a claim for trespass or conversion at the Disputes Tribunal. The correct process is to give reasonable notice as per the agreement, then seek a court order if the flatmate still refuses to leave. Self-help remedies rarely hold up.
How to Resolve a Flatmate Dispute Step by Step
Start with a direct conversation
Before involving any tribunal or third party, talk to the flatmate directly. The OUSA support guide recommends raising issues early and choosing a time when neither person is under pressure. Avoid confronting someone late at night or after drinking. State the problem clearly and what you want to change. Most disputes at this stage are about habits, not money, and a calm conversation can reset expectations.
Call a flat meeting to renegotiate terms
If a direct conversation does not work, or if the issue affects the whole house, call a flat meeting. This is not a formal legal step, but it serves a practical purpose. A meeting allows everyone to air their view and agree on new rules. The OUSA guide suggests using this moment to renegotiate the flatmate agreement if circumstances have changed. Write down any new agreements and have everyone sign. A photo of the signed page counts as evidence if the dispute later goes to tribunal.
Try mediation before going to tribunal
Tenancy Services offers free mediation for landlord-tenant disputes, but flatmate disputes are not covered by that service. However, private mediation is an option, and some community organisations offer low-cost mediation for flatmates. The goal is to reach a written agreement that both sides can sign. If mediation fails, the next step is the Disputes Tribunal. The YouthLaw guide notes that under-25s can contact YouthLaw for advice, and everyone else can contact their local Community Law Centre for free help.
Apply to the Disputes Tribunal
The Disputes Tribunal is the correct forum for flatmate disputes that cannot be resolved by agreement. The process works like this: the applicant files a claim online or at a local Ministry of Justice office. The tribunal then lists a hearing, usually within a few weeks. At the hearing, an independent referee listens to both sides and makes a binding decision. The tribunal can order the payment of money, the return of property, or the performance of a specific action. Legal representation is generally not allowed, so you present your own case. The filing fee is relatively low, and the process is designed to be accessible without a lawyer. For any dispute involving legal grey areas, you might consider using a landlord-tenant law service to check your position before filing.
Upcoming changes that could affect flatmates
New Zealand’s rental laws have been evolving steadily, and flatmate arrangements are not immune to future reform. The Healthy Homes Standards already apply to rental properties, and the head tenant is responsible for ensuring the property meets those standards. Any future changes to the RTA that tighten subletting rules or impose new obligations on head tenants will directly affect flatmate arrangements. Keeping an eye on Tenancy Services updates is the best way to stay ahead of changes that could shift the balance of rights and responsibilities in shared housing.

A Written Agreement Is the Best Argument You Never Have
The most reliable way to avoid a flatmate feud is also the simplest: a written agreement signed before anyone moves in. The flat/house sharing agreement template from Tenancy Services covers rent, bond, chores, notice periods, and guest policies. It is not a legal requirement, but it becomes the reference point when memories differ. For head tenants, it also provides a clear record that the flatmate is not a tenant under the RTA, which reduces the risk of a later claim for tenant status.
What I tend to notice is that the houses with a written agreement resolve disputes faster because the rules are already on paper. The agreement does not need to be complicated. Two pages, signed and dated, with a clause stating the RTA does not apply, is enough to keep most disputes out of a tribunal hearing.
