The landlord may give 42 days' notice in writing if:
(a) the landlord has an agreement to sell the premises with
vacant possession; or
(b) the premises are required for occupation by the landlord
or a member of the landlord's family; or
(c) the premises are required for an employee of the landlord
and this has been agreed at the start of the tenancy.
In other cases, the landlord must give 90 days' notice in
writing.
If the fixed term is for longer than 90 days, the tenancy will automatically become a periodic tenancy when it expires unless the landlord or the tenant gives notice to say they don’t want that to happen. This notice must be given between 90 and 21 days before the end of the fixed term:http://tenancy.govt.nz/assets/Fo ... ritten-template.pdf
