Sharing a flat in New Zealand with a verbal agreement might feel fine at first, but thousands of disputes happen every year because nothing was written down. Without a signed document, the person who paid the bond has no receipt, and a verbal notice to leave has no proof. Flat sharing in New Zealand is not covered by the Residential Tenancies Act 1986, which means the usual tenant protections don’t apply. A written flat-sharing agreement is the only document that gives both parties enforceable rights.

Most people assume a handshake and a shared bank transfer are enough. They aren’t. If you’re a flatmate paying rent to a tenant, you have no protection under the RTA. If your landlord lives on-site, the same applies. Short-term boarders and lodgers are also excluded and have no access to the Tenancy Tribunal. Here’s what you actually need to know.
The central concept here is a flat-sharing agreement.
What I tend to notice is that people only think about this after something goes wrong. A signed agreement written before anyone moves in saves a lot of hassle. If you’re unsure about the legal side of things, it’s worth getting a second opinion from a landlord-tenant law service to check your specific situation.
What a flat-sharing agreement actually costs and covers
The cost of a written agreement is minimal compared to what you lose without one. A digital flat-sharing agreement can be created, sent, signed, and stored in minutes. The real cost is the time spent sorting out a dispute that could have been avoided.
Without a written agreement, the person who paid a bond has no receipt. That means if a flatmate leaves early and the bond is disputed, there’s no proof of who paid what. The same goes for rent payments and shared bills. Verbal notice has no proof either, so you can’t reasonably enforce departure terms if nothing is written down.
Disputes not covered by the RTA must go to the Disputes Tribunal. That process requires its own documentation and has a $30,000 claim limit. The Tribunal is cheaper than court, but it still takes time and energy. A written agreement provides clear terms that the Tribunal can use to make a decision.
Here’s a breakdown of what a good flat-sharing agreement should include and what happens if it’s missing:
→ Scroll right to see all columns
| Item in agreement | What it covers | Risk if missing |
|---|---|---|
| Property address and parties | Who lives where and who is responsible | Unclear who is liable for damage or rent |
| Rent and bond amount | How much is paid and who paid the bond | No proof of bond payment; rent disputes |
| Start date and term | When the arrangement begins and ends | Can’t enforce move-out dates |
| Expense share | How bills, food, and cleaning costs are split | Unfair cost distribution; resentment |
| Notice period | How much warning is needed to leave | Can’t enforce departure terms |
| Special conditions | Guests, pets, noise, cleaning schedules | Ongoing arguments about house rules |
If you’re the tenant who signed the original lease, you’re the one on the hook if a flatmate stops paying. A written agreement with your flatmate doesn’t change your obligation to the landlord, but it gives you a way to recover the money.

Common flatmate agreement mistakes and how to fix them
Relying on a verbal agreement
The most common mistake is assuming a verbal arrangement is enough. Thousands of disputes happen every year because nothing was written down. Without a written agreement, you have no proof of the terms. If a flatmate stops paying rent or leaves without notice, you can’t enforce anything. The fix is simple: write it down before anyone moves in. Use a digital platform to create, send, sign, and store the agreement. That way, both parties have a copy.
Not specifying the notice period
Without a written notice period, you cannot reasonably enforce departure terms. If a flatmate wants to leave tomorrow, there’s nothing you can do. The same applies if you want them to leave. A standard notice period is usually 21 or 28 days, but it should be written into the agreement. If you’re the tenant on the lease, you also need to check what notice period your landlord requires.

Ignoring the bond paperwork
The person who pays the bond needs a receipt. Without a written agreement, there’s no proof of who paid what. If the bond is disputed when someone moves out, the person who paid it has no way to prove it. The fix is to include the bond amount and who paid it in the written agreement. If the bond is held by the landlord or a tenancy service, make sure the flatmate’s name is on the paperwork.
Not defining how bills are split
Arguments about power, internet, and food costs are one of the most common sources of flatmate conflict. Without a written agreement, there’s no clear rule for how expenses are shared. The fix is to specify exactly how bills are split — equally by person, by room size, or by usage. Include what happens if someone is away for a week or a month. A bill splitting app can help track shared costs, but the agreement should still state the method.
How to set up a flat-sharing agreement that works
Drafting the agreement before anyone moves in
The agreement should be written before the first flatmate moves in. Include the property address, both parties’ full names, the rent amount, the bond amount, and who paid it. Specify the start date and whether the term is fixed or periodic. List how expenses are shared and what happens if someone doesn’t pay. Add special conditions for guests, pets, noise, and cleaning. Both parties should read it carefully before signing.
Sending and signing digitally
Digital platforms let you create, send, sign, and store the agreement in minutes. Both parties get a copy, and there’s no risk of losing the paper version. The signed document is stored securely and can be accessed later if needed. This is especially useful if a dispute goes to the Disputes Tribunal, because you have a clear record of what was agreed.
What to do when a flatmate leaves
When a flatmate gives notice, check the written agreement for the notice period. If they leave without proper notice, you can use the agreement to recover the rent owed. If a new flatmate moves in, write a new agreement or update the existing one. The bond should be transferred or refunded according to the terms. If there’s damage, the agreement should state how the cost is split.
Upcoming changes to flatmate rights
There’s ongoing discussion in New Zealand about extending some tenancy protections to flatmates. Nothing has changed yet, but it’s worth keeping an eye on. If the law does change, flat-sharing agreements will still be important because they provide a clear record of what was agreed. For now, the Residential Tenancies Act does not cover flat shares, so a written agreement is your only protection.

Why a written agreement is the only real protection for flatmates
Flat sharing in New Zealand sits outside the usual tenancy laws, which means the standard safety nets don’t apply. A written flat-sharing agreement is the only document that gives both parties enforceable rights. Without it, you’re relying on goodwill and memory, which rarely holds up when money is at stake. The cost of setting one up is negligible compared to the cost of a dispute.
