Otago landlords with unruly tenants are being told to give them the boot before a law change makes that even harder to do.
But the group representing tenants' rights said the move was "highly unethical".
Limitations to terminating a rental were among new changes to tenancy rules that come into effect next February.
Landlords would need firm evidence, such as video of several anti-social events before going to the Tenancy Tribunal.
Property expert Sara Hartigan joined The One Roof Radio Show on The Weekend Collective to share her advice.
