It is common for tenancies in New Zealand to be fixed term for a period of 12 months. The length of term will be included in your tenancy agreement. Before you sign your agreement, make sure the term is right for you because you cannot give notice to end the tenancy early without incurring cost. Once your fixed term tenancy ends, the tenancy will become periodic. You must give notice in writing at least 21 days before the term ends if you don't want this to happen.
