How long can a tenant have a guest stay in NZ?

Under the Residential Tenancies Act, tenants have a right to quiet enjoyment, which includes having guests. Landlords cannot legally ban guests or limit their stay.

However, a guest becomes an occupant if they stay long-term, move in furniture, contribute to rent, or receive mail. If this exceeds the tenancy agreement's occupant limit, a landlord can issue a 14-day notice to remedy. Unresolved issues can be taken to the Tenancy Tribunal for mediation.
