How much can my landlord increase my rent by?

In New Zealand, landlords can increase rent only once every 12 months, and not within the first year of a tenancy. They must provide at least 60 days' written notice before the new rate applies.

While there's no legal cap on the amount, any increase must be reasonable and aligned with market rates. If you believe a rent hike is excessive, you can challenge it at the Tenancy Tribunal. Use Trade Me Property to research comparable local rents.
