Rent increases in New Zealand: 60 days’ notice and the 12-month rule

Two numbers decide whether a rent increase stands: 60 days and 12 months.

28 October 2026 · 4 min read

The rules

  • At least 60 days’ notice, in writing (28 days in a boarding house).
  • The increase can take effect only 12 months after the last increase took effect, and 12 months after the tenancy started.
  • The notice can be given before the 12 months are up, as long as the increase itself does not start until they are.
  • During a fixed term, rent can go up only if the tenancy agreement allows it.
  • A bond top-up can be asked for when the rent goes up.

Where it goes wrong

  • Notice given less than 60 days before the new rent starts.
  • An increase that starts less than 12 months after the last one.
  • An increase during a fixed term the agreement does not allow.
  • An increase served after the tenancy has already been given notice to end.

Checked before it is served

Propex checks a proposed rent increase against these rules before the notice is produced, and says why when it cannot go ahead: too soon, notice too short, served too late, or not an increase at all. On the day the new rent starts, it is applied to the tenancy; if it no longer can be, the person who proposed it is told.
