Flatmate Agreement (New Zealand)

A Flatmate Agreement (New Zealand) in New Zealand a Flatmate Agreement is a private written arrangement between the head tenant and one or more flatmates who share a rented property in New Zealand. Flatting — sharing a house, flat, or apartment with others — is an integral part of New Zealand's rental culture, particularly in major cities like Auckland, Wellington, Christchurch, and Dunedin, where high property prices and living costs make shared living a practical and popular choice for students, young professionals, and anyone seeking affordable housing.

One of the most important things to understand about a flatmate agreement in New Zealand is that flatmates are NOT covered by the Residential Tenancies Act 1986 (RTA). The RTA applies only to the formal relationship between the landlord and the person or persons named on the tenancy agreement — the tenant or co-tenants. A flatmate who is not named on the tenancy agreement does not have the legal protections of the RTA and cannot apply to the Tenancy Tribunal to resolve disputes with the landlord or with the head tenant. This means that flatmate disputes must be resolved through direct negotiation, community mediation, the Disputes Tribunal (for financial claims under $30,000), or the District Court.

Because flatmates lack the statutory protections of the RTA, a well-drafted flatmate agreement is essential for establishing clear rights and obligations between the head tenant and the flatmates. The agreement sets out all the key terms of the shared living arrangement: rent contributions, bond arrangements, utilities splits, cleaning duties, food sharing arrangements, notice periods for moving out, the process for replacing a departing flatmate, visitors policies, and any house-specific rules.

A flatmate agreement typically covers the following parties: the head tenant (the person whose name is on the formal tenancy agreement with the landlord, who is solely responsible to the landlord for rent and compliance with the RTA), and one or more flatmates (who pay rent and utility contributions to the head tenant under the private flatmate agreement). The head tenant bears the risk of flatmates not paying their contributions — if a flatmate fails to pay their share, the head tenant remains fully obligated to pay the full rent to the landlord.

New Zealand's flatting culture has developed a set of commonly understood norms and expectations about how flats are run. Rent is typically paid weekly, utilities are split equally between all flatmates, cleaning is managed by a rotating roster, food is usually kept separate (though some shared staples are common), and flatmates are generally expected to give two to four weeks' notice before moving out. A flatmate agreement codifies these expectations in a legally binding document and provides a clear reference point if any dispute arises.

The agreement also addresses the important question of bond contributions. The bond paid to Tenancy Services (MBIE) under the tenancy agreement is the head tenant's responsibility, but in practice, flatmates typically contribute proportionally to the bond. The agreement should clearly record each flatmate's bond contribution and specify how it will be returned at the end of the tenancy after any valid deductions have been agreed.

A Flatmate Agreement is needed whenever two or more people share a rented property in New Zealand where only one person (the head tenant) is named on the formal tenancy agreement with the landlord. In this situation, the other occupants are flatmates rather than co-tenants, and a flatmate agreement is the appropriate document for establishing the rights and obligations between them.

The most common situation is when a head tenant takes in one or more flatmates to help share the cost of rent and living expenses. This is especially common in New Zealand's larger cities, where rental costs have risen significantly. A flatmate agreement should be signed before any flatmate moves in, so that all parties understand the terms of the arrangement from the outset.

A flatmate agreement is also needed when an existing flatmate is replaced by a new person. The new flatmate should sign the agreement (or a new version of it) before moving in, and any changes to rent shares, room allocations, or utilities arrangements should be updated at that time. Without a signed agreement, there is no clear record of what was agreed with the new flatmate, and disputes about rent, utilities, or bond contributions become much harder to resolve.

The agreement is also important when the flatmates have agreed on specific arrangements that differ from common defaults — for example, unequal rent shares (because rooms differ significantly in size or amenities), shared grocery costs, or specific cleaning responsibilities. Having these arrangements in writing prevents misunderstandings and provides evidence if a dispute arises.

In situations where the head tenant is planning to travel, work overseas, or is temporarily absent, a flatmate agreement provides clarity about who is managing the property in the head tenant's absence and how bills and rent will be handled during that period.

Finally, a flatmate agreement is useful for establishing clear house rules about matters like smoking, pets, noise, parking, and the use of shared facilities. Many flatmate conflicts in New Zealand arise from differing expectations about these matters, and a written agreement that all flatmates have signed provides an objective reference point for resolving any disagreement.

Because flatmates are not covered by the Residential Tenancies Act 1986, having a written flatmate agreement is the primary legal protection available to both the head tenant and the flatmates. Without it, either party is in a significantly weaker position if a dispute arises about rent, bond, or the right to remain at the property.

A well-drafted New Zealand Flatmate Agreement must address all the key elements of the shared living arrangement to provide clarity and reduce the risk of disputes between the head tenant and flatmates.

The parties and property section must correctly identify the head tenant by full legal name with contact details, and list all flatmates by their full legal names with contact details and room allocations. The full address of the property and a description of the shared and private areas should also be included.

The important legal disclaimer about the RTA not applying to flatmates should be prominently included in the agreement. Both the head tenant and all flatmates should understand that their rights and obligations are governed by this private agreement and not by the Residential Tenancies Act 1986, and that disputes are resolved through the Disputes Tribunal or the District Court rather than the Tenancy Tribunal.

The rent and bond section is the financial core of the agreement. It must specify the total rent payable to the landlord, each flatmate's weekly rent contribution, the due day and payment method for rent contributions, the head tenant's bank account number, and each flatmate's bond contribution with a clear explanation of how bond contributions will be managed and returned at the end of the tenancy.

The utilities and internet section must specify how electricity, gas, water (if separately metered and charged), and internet costs are split — typically equally between all flatmates — and who is named on each account. The process for sharing bills and recharging costs to flatmates should be clear.

The shared spaces and cleaning section should identify all shared areas and set out the agreed cleaning arrangement, whether a rotating roster, assigned areas, or communal cleaning days. Specific cleaning standards and expectations should be described to avoid the most common source of flatmate conflict.

The food and groceries section should specify whether food is kept separate, shared, or a mixture of both, and any specific conventions about labelling and storage that the flatmates have agreed.

The notice period section must specify how much written notice a flatmate must give before moving out (typically two to four weeks in New Zealand), the method for giving notice, and the head tenant's right to ask a flatmate to leave with equivalent notice. The disclaimer about the Tenancy Tribunal having no jurisdiction over flatmate eviction disputes should be included.

The replacing a flatmate section should explain the process for finding and approving a new flatmate when someone moves out, including the requirement for the remaining flatmates' agreement and the landlord's consent (if required under the tenancy agreement).

Additional sections should address visitors and overnight guests, and any house-specific rules about smoking, noise, pets, parking, and shared equipment use.

Finally, the agreement must be signed by the head tenant and all flatmates, with dates recorded. All parties should receive a signed copy. Under Section 34 of the Contract and Commercial Law Act 2017, an enforceable flatmate agreement requires offer, acceptance, and consideration. Tenancy Services (Ministry of Business, Innovation and Employment) administers the Residential Tenancies Act 1986 but has no jurisdiction over flatmate arrangements under Section 13 of that Act; the Bond Centre holds bond monies lodged by head tenants under Section 18. The Disputes Tribunal Act 1988 (administered by the Ministry of Justice) establishes the Disputes Tribunal of New Zealand, which resolves flatmate financial disputes up to NZD 30,000 — covering unpaid rent contributions, bond deduction disputes, and utility cost recovery. Hearings are conducted by a Referee at district registries in Auckland, Wellington, Hamilton, Tauranga, Christchurch, and Dunedin. For claims exceeding NZD 30,000, the District Court of New Zealand has jurisdiction under the District Court Act 2016. Section 11 of the Privacy Act 2020, enforced by the Office of the Privacy Commissioner, governs how personal information collected during the flatmate screening process — including identity documents and IRD numbers — must be stored and used. Section 11 of the Limitation Act 2010 imposes a six-year limitation period on contract claims arising from flatmate agreements. Citizens Advice Bureau offices and Community Law Centres across Auckland, Wellington, Christchurch, Hamilton, and Dunedin provide free legal guidance on flatmate disputes. WorkSafe New Zealand and the Employment Relations Authority have no jurisdiction over private flatmate arrangements. The Inland Revenue Department (IRD) may have interest in flatmate arrangements where the head tenant generates rental income.
