The Big One: 60 Days’ Notice (and Why It Matters)
Let’s start with the non-negotiable. Under the Residential Tenancies Act, landlords must give at least 60 days’ written notice before a rent increase takes effect. That’s for standard tenancies. Boarding houses operate under a different set of rules, with a shorter 28-day notice period, but for most Hibiscus Coast landlords, 60 days is the number to remember.
The notice itself must be in writing, and it needs to spell out two things clearly: the new rent amount and the exact date the increase kicks in. How you deliver that notice matters too. You can hand it to the tenant in person, pop it in their letterbox, send it by post, or email it if you’ve both agreed to electronic communication. Each delivery method has its own timing rules for when the notice is officially considered served, so don’t leave it to the last minute. A good habit is to use the official Tenancy Services notice template. It’s free, straightforward, and removes the guesswork. A small technical slip-up, like forgetting to include the effective date, could invalidate the whole process, and nobody wants to start the 60-day clock all over again.
The 12-Month Rule: Yes, You Really Have to Wait
Here’s another rule that trips people up. You can only increase the rent once every 12 months. That changed back in August 2020, when the frequency shifted from every six months to once a year. If you’ve been managing properties for a while, don’t let old habits creep back in. The 12-month clock starts ticking from the date the last increase actually took effect, not from the date you gave notice. That’s an important distinction.
What if you’ve just bought a tenanted property? You inherit the existing tenancy as is, including the rent review timeline. You can’t reset the clock simply because you’re the new owner. If the previous landlord increased the rent four months ago, you’ll need to wait another eight months before you can consider another increase. This applies whether the tenancy is periodic or fixed-term, though fixed-term agreements come with their own extra layer of rules, which we’ll get to shortly.
Fixed-Term Tenancies: A Different Set of Rules
Fixed-term tenancies are a slightly different beast. During a fixed term, you can only increase the rent if the tenancy agreement specifically includes a rent review clause. Without that clause, the rent stays locked in for the entire duration of the fixed term. No exceptions, no workarounds.
If your agreement does have a rent review clause, you still need to follow the standard rules: 60 days’ written notice and no more than one increase every 12 months. Once the fixed term ends and the tenancy rolls over into a periodic arrangement, the usual 12-month rule applies without the need for a special clause. It’s worth checking your existing agreements now, especially if you’ve been using a standard template for years. A quick review could save you a headache later.
How Much Can You Increase Rent? (The Tricky Question)
Now for the question everyone asks. New Zealand law doesn’t set a maximum percentage or dollar amount for rent increases. There’s no cap. But, and this is a big but, the increase must be in line with fair market rates for similar properties in your area.
What does “fair market rate” actually mean? It means looking at properties of a similar size, condition, location, and set of amenities and comparing them to yours. On the Hibiscus Coast, that might mean checking what a three-bedroom home with a garage in Orewa rents for compared to a similar property in Stanmore Bay or Manly. If your increase is significantly above what the local market supports, your tenant can apply to the Tenancy Tribunal within 21 days of receiving your notice. A practical step before you set a new figure is to get a current rental appraisal. We offer these free, and they give you a realistic picture of where your property sits in the local market. It’s a simple way to make sure you’re in the right ballpark before you put anything in writing.
What About Bond Top-Ups and Paperwork?
When the rent goes up, the bond often needs to follow. You can ask your tenant to top up their bond so the total stays at a maximum of four weeks’ rent. So if the existing bond was calculated on the old rent, the tenant pays the difference to bring it in line with the new amount.
As of 29 June 2026, all bond transactions moved online through Bond Hub. The days of paper forms are behind us. Once you receive the top-up payment from your tenant, you have 23 working days to lodge it digitally. Keep clear records of everything along the way: the notice you served, when and how you delivered it, any correspondence with the tenant, and the bond lodgement confirmation. Good record-keeping isn’t just tidy admin; it’s your best defence if a dispute ever arises.
What If the Tenant Disputes the Increase?
Tenants have the right to push back, and they have 21 days from receiving your notice to apply to the Tenancy Tribunal. The most common grounds for dispute are that the increase isn’t in line with local market rates, proper notice wasn’t given, or the 12-month rule wasn’t followed.
If the Tribunal finds the increase is unreasonable, it can reduce the amount or cancel it altogether. That’s why getting it right from the start saves everyone time and stress. If you’re unsure about market rates or notice procedures, having a property management team in your corner can make the process far smoother. They handle the details so you don’t have to second-guess yourself.
Can You Ever Decrease Rent? (Yes, Sometimes)
Rent reductions aren’t just for the tenant’s benefit. They can be a practical tool for landlords too. If part of the property becomes temporarily unusable, say a bedroom is out of action while repairs are underway, a temporary reduction might be the fair and sensible move.
There’s also the strategic angle. If market rents have dipped and you’ve got a great tenant you’d rather keep, offering a voluntary reduction can be a smart long-term play. The best part is that reductions don’t have to follow the same strict notice rules as increases. You and your tenant can agree on a new amount at any time, as long as it’s recorded clearly.
Common Mistakes Landlords Make (and How to Avoid Them)
Even experienced landlords slip up from time to time. One classic error is not giving the full 60 days’ notice, often because they’ve counted from the wrong date. Another is trying to increase rent during a fixed term without a rent review clause in the agreement. Forgetting the 12-month rule and moving too soon is surprisingly common too, especially after a change in ownership.
Setting an increase that’s out of step with local market rates is another pitfall. Tenants talk, and the Tribunal listens. And finally, not keeping proper records of when and how notice was served can leave you with nothing to fall back on if the timeline is questioned. A little diligence upfront goes a long way.
Feeling Overwhelmed? You Don’t Have to Go It Alone
Rent increases are just one piece of the compliance puzzle, and getting it wrong can be costly. A good property management team handles the timing, the paperwork, and the communication so you don’t have to lie awake wondering if you’ve missed a step. Whether you’re after full management or just a helping hand with tenant placement, having local expertise on your side makes all the difference.
