Why Every Flat-Share Needs a Written Rental Agreement
Flat sharing in New Zealand is not covered by the Residential Tenancies Act — which means without your own written agreement, you have very limited legal protection without your own written agreement.
Not covered by law
Flatmate arrangements between tenants are excluded from the NZ Residential Tenancies Act 1986.
Agreements fill the gap
A written flat-sharing agreement is the only document that gives both parties enforceable rights.
Flathive makes it simple
Create, send, sign, and store your rental agreement digitally — in minutes, not days.
The problem
Why do so many flat-shares have no written agreement?
In New Zealand, most people know they should have a tenancy agreement when renting from a landlord. But when it comes to flat sharing — where a tenant rents a room from another tenant, or where friends move in together — written agreements are rarely used. The common assumption is that things will just work out, or that only "official" rentals need paperwork.
That assumption leads to thousands of disputes every year where one party has no documentation to support their version of events. Without a written agreement, the person who paid a bond has no receipt. The flatmate who gave notice verbally has no proof. The head tenant who is owed unpaid rent has no agreed terms to point to.
The fix is straightforward — a written flat-sharing agreement takes less than ten minutes to create and can prevent months of conflict.
Flathive lets you create a digital flat-sharing agreement in minutes. Fill in the details, send it to both parties, and get it signed — all in one place, with no paperwork required.
Why agreements matter
Six reasons a written agreement protects you
Proof of what was agreed
A written agreement is the only reliable record of rent amount, bond, notice period, and house rules. Verbal agreements are nearly impossible to prove in any dispute.
Protection for both sides
An agreement protects the head tenant or homeowner if a flatmate disappears owing rent, and protects the flatmate if their bond is unfairly withheld.
Clear grounds for the Disputes Tribunal
Without a written agreement, it becomes much harder to prove what was agreed in a dispute.. A signed agreement gives the Tribunal clear terms to enforce.
Sets expectations from day one
Most flatmate conflicts come from unclear expectations — not bad people. An agreement removes ambiguity before it becomes resentment.
Enforceable notice periods
Without a written notice period, you cannot reasonably require a flatmate to give you two weeks or more before leaving. The agreement gives that clause teeth.
Bond recovery
If a flatmate leaves without paying the last week's rent or causes damage, a signed agreement and bond receipt gives you grounds to recover those costs legally.
The legal gap
Why flat sharing is not covered by the NZ Residential Tenancies Act
The Residential Tenancies Act 1986 (RTA) is the law that protects tenants in New Zealand. It governs the relationship between landlords and tenants, sets bond rules, and gives access to the Tenancy Tribunal. But flat-sharing arrangements — where a tenant rents a room to another person — are largely excluded from its protection.
Flatmates paying rent to a tenant — not the landlord
The RTA covers the relationship between a landlord and the principal tenant only. If you are a flatmate paying rent to the head tenant, you are not protected by the Act.
Shared accommodation with the property owner
If the landlord also lives in the property, the arrangement is specifically excluded from the RTA under Section 5.
Boarder and lodger arrangements
Short-term boarders, particularly where meals or services are provided, fall outside the RTA and have no access to the Tenancy Tribunal.
No access to the Tenancy Tribunal
Tenancy Tribunal is only for RTA-covered tenancies. Flatmate disputes must go to the Disputes Tribunal — which requires its own documentation to be effective.
What this means for you
If you are a flatmate and a dispute arises — over bond, unpaid rent, damage, or notice — you cannot go to the Tenancy Tribunal. You must use the Disputes Tribunal, which has a claim limit of $30,000 and requires you to bring your own evidence. A signed flat-sharing agreement is the most important piece of evidence you can have.
What to include
What should a flat-sharing agreement cover?
A good flat-sharing agreement does not need to be long or complicated. It just needs to cover the essentials clearly so that both parties understand their obligations from day one.
Property address
Full address including suburb and city
Both parties' details
Full name, email, phone, and service address
Rent and bond
Weekly rent amount, bond weeks, and payment day
Start date and term
Fixed term or periodic, with an end date if applicable
Expense share
Percentage of bills the flatmate is responsible for
Special conditions
Pets, smoking, guest rules, or anything else agreed upfront
Without a written notice period, you cannot reasonably enforce departure terms. If a flatmate decides to leave tomorrow with no warning, you have very limited options without an agreement that specifies the required notice.
How Flathive helps
Creating your rental agreement with Flathive
Flathive provides a complete digital rental agreement flow designed specifically for flat-sharing arrangements in New Zealand. No legal knowledge required — just fill in the details and the platform handles everything else.
Create the agreement
The landlord or head tenant fills in the property address, both parties' details, rent, bond, payment day, agreement type (fixed term or periodic), and any special conditions.
Send for signing
Flathive generates a unique signing link for each party and emails it directly. No account is needed — each person clicks their link and reviews the full agreement.
Each party signs digitally
Using the built-in e-signature tool, each party draws or types their signature. The signature is placed directly into the agreement document at the correct field.
Flathive certifies the document
Once both parties have signed, Flathive generates a final certified PDF with a final PDF with a verification record and timestamp for both parties printed on the agreement.
Both parties receive a copy
The signed agreement is available to download immediately. Both the landlord and flatmate receive their own copy — stored securely on the platform.
The entire process — from creating the agreement to getting both parties' signatures — can be completed in under ten minutes. Both parties receive a certified copy of the signed document automatically.
Every signed agreement is certified
When both parties sign on Flathive, the final PDF is stamped with a Flathive certification seal that includes a unique SHA-256 verification code generated from the signing data. This makes the document tamper-evident — if anyone alters it after signing, the code will no longer match the platform's records.
The verification code is printed directly on the document, giving the Disputes Tribunal a concrete way to verify authenticity if a dispute ever arises.
Common questions
Frequently asked questions
Is a digital signature legally valid in New Zealand?
Yes. Under the Contract and Commercial Law Act 2017, electronic signatures are legally recognised in New Zealand for most types of agreements. A flat-sharing agreement signed digitally carries the same legal weight as a handwritten signature.
What happens if a flatmate refuses to sign?
You can still proceed — but an unsigned agreement only protects the party who was willing to sign. If a prospective flatmate refuses to sign any form of written agreement, that is a meaningful signal worth taking seriously before they move in.
Can I use this agreement if the landlord also lives in the property?
Yes. Flathive's flat-sharing agreement is designed for these situations specifically. Since the RTA does not cover arrangements where the owner lives on site, a private written agreement is even more important in this context.
How do I use the agreement if a dispute goes to the Disputes Tribunal?
Bring the signed PDF with the verification code. The Disputes Tribunal will review the agreed terms — rent amount, notice period, bond — and apply them. The certification seal on the Flathive document shows it has not been altered after signing.
Is Flathive's rental agreement only for NZ?
The current flat-sharing agreement template is tailored for New Zealand law and uses NZ-specific terminology. Australian arrangements have different regulatory contexts and are being addressed separately.
Ready to create your rental agreement?
It takes less than ten minutes. Both parties sign digitally, and you both receive a certified copy automatically.
