Flatting arrangements are common in New Zealand, but managing flatmate changes within a fixed-term tenancy can be complex. This article explains the legal and practical considerations for landlords and tenants.
Are Flatmates Covered by Tenancy Law?
Only the tenants named on the tenancy agreement have legal rights and responsibilities under the Residential Tenancies Act (RTA). Flatmates not on the lease have no direct legal standing.
Can Tenants Swap Flatmates?
Generally, tenants cannot replace themselves or add new flatmates without landlord consent, especially during fixed-term tenancies. The landlord’s written approval is essential to avoid breach of contract.
What Happens if a Flatmate Leaves?
The tenancy remains in effect until the fixed term ends, with all tenants jointly and severally liable for rent and property care—even if one tenant leaves.
Practical Tips for Flatmate Changes
- Tenants should notify the landlord or property manager promptly about any changes
- New flatmates should complete reference and background checks
- Landlords may require a deed of assignment or a new tenancy agreement for replacement tenants
