How often can rent be increased in NZ?

Rent cannot go up more than once in any 12 month period, and it cannot go up at all during the first 12 months of a tenancy. The clock runs from the date the last increase took effect, not from when notice was given. So a tenant who started in March with an increase the following March cannot face another until March the year after. The rule follows the tenancy, so a change of property manager or owner does not restart anything.

This is one of the most useful questions to ask before signing: when did the rent last change? The answer tells you when the next change becomes possible.

An increase only takes effect if the landlord gives written notice at least 60 days before the new rent starts, stating the new amount and the date it applies from. A comment at the door or a message saying rent is going up soon does not start anything.

If the notice is short or informal, the increase does not take effect on the stated date. Keep the notice itself, because the dates on it are what matter if there is ever a disagreement.

During a fixed term, rent can only be increased if the tenancy agreement specifically provides for it, and the 12 month and 60 day rules still apply on top. If the agreement is silent, the rent is locked until the term ends. This is worth checking before signing a longer fixed term: a two year tenancy with no rent review clause is a two year price. Some agreements tie reviews to specific dates or formulas, so read the clause rather than assuming.

There is no legal cap on how much rent can rise, but the law does not leave tenants without options. If the new rent is substantially above what similar properties in the area go for, you can apply to the Tenancy Tribunal, which can set the rent at market level.

Tenancy Services publishes market rent figures by area, drawn from lodged bonds, and that is the evidence to start with. Most of the time, though, the practical first step is a conversation: landlords with good tenants often have room to move.
