How often can my landlord increase the rent in NZ?

Under s24 of the Residential Tenancies Act 1986 (as amended), landlords are restricted in how often they can increase rent.

The rules:

• Rent can only be increased once every 12 months
• The landlord must give you at least 60 days written notice of the increase
• The notice must specify the new rent amount and the date it takes effect

If the notice period isn't met: A rent increase with insufficient notice is not valid. You are not required to pay the increased amount until valid notice has been given and the 60-day period has passed.

Challenging an excessive increase: If you believe a rent increase is excessive compared to market rates, you can apply to the Tenancy Tribunal for a review. The Tribunal can order that the increase be reduced or set aside.

Fixed-term tenancies: During a fixed term, rent can only be increased if the tenancy agreement expressly provides for it, and the 12-month and 60-day rules still apply.

Note: The rules changed in 2021. Before 12 August 2021, landlords could increase rent every 180 days. If your situation predates this, check which rules applied.
