How Often Can a Landlord Increase Commercial Rent In New Zealand?

If you’re running a small business, rent is usually one of your biggest ongoing costs.

So when you get an email from your landlord saying it’s time for a rent review (and the numbers look… higher than you expected), it can feel like the ground shifts under you.

The good news is: in New Zealand, a landlord generally can’t increase commercial rent whenever they feel like it. In most cases, rent increases are driven by what the lease says (because there isn’t a single “one-size-fits-all” statutory rule for commercial rent reviews). That means rent should only change if the lease allows it - and the lease should spell out how and when a commercial lease rent review can happen.

Below, we’ll break down how commercial rent reviews typically work, how often they can happen, what methods are used, and what you can do to protect your business before you sign (and when a review is coming up).

What Is A Commercial Lease Rent Review (And Why Does It Matter)?

A commercial lease rent review is the process in your lease that lets the rent be adjusted during the lease term (and often at renewal). It’s one of the most important lease clauses for small businesses because it affects:

• Cashflow (your monthly outgoing can jump quickly)
• Pricing decisions (you may need to increase your prices to keep up)
• Business viability (especially for hospitality and retail where margins can be tight)
• Exit planning (it can affect whether you can afford to stay, sell, or relocate)

In many commercial leases, rent reviews aren’t “negotiated later” - they’re locked into the contract from day one. That’s why it’s worth getting the lease reviewed before you sign, including the rent review mechanism and timing. A good starting point is having a Commercial Lease Review so you’re clear on what’s coming and where you can negotiate.

It’s also worth remembering that “rent” in a commercial lease usually isn’t just your base rent. Your total occupancy cost may include outgoings (and sometimes other charges), so a rent review can be only one part of the overall picture.

How Often Can A Landlord Increase Rent In A Commercial Lease?

Most of the time, the answer is simple: your landlord can increase rent only as often as your lease allows.

In New Zealand, commercial leases commonly provide for rent reviews at set intervals. Often, that might be:

• Every year (annual reviews)
• Every 2 years
• Every 3 years
• At renewal (when you exercise a right of renewal, if your lease has one)

It’s also common for leases to include different types of reviews across the term, such as a CPI adjustment one year and a market review later.

Where Do You Find The Rent Review Frequency?

The frequency and timing usually appear in one (or more) places:

• The Schedule to the lease (often a table with dates and figures)
• A specific rent review clause in the main body of the lease
• The renewal clause (which may say rent is reviewed when you renew)

If you’re unsure what your lease actually says, it’s often quicker (and cheaper) to clarify early than to argue later. This is where having a lawyer review your Commercial Tenancy Agreement can help you spot how the review is triggered and what notice requirements apply.

Can A Landlord Increase Rent Mid-Year Or Outside The Review Date?

Generally, not unless the lease allows it. In a typical lease, rent changes only on:

• the specified rent review dates
• renewal dates (if you renew)
• other specific trigger events written into the lease (less common)

That said, some leases can include additional cost-related mechanisms (for example, outgoings reconciliations or increases in operating expenses). Those aren’t always “rent reviews” in name, but they can still increase what you pay overall.

What About “Ratchet Clauses” And Minimum Increases?

Some leases include terms that effectively prevent rent going down even if the market drops (often called a “ratchet” style effect). These clauses can be a big deal if you’re signing up in a hot market and conditions later cool.

Whether a clause is acceptable depends on your industry, bargaining power, and the location - but it’s something you want to understand before you commit.

What Are The Common Types Of Commercial Lease Rent Review In NZ?

Not all rent reviews work the same way. Understanding the method matters because it influences how predictable your rent increases will be.

1) Market Rent Review

A market rent review adjusts the rent to what comparable premises would rent for on the open market at the review date. This can be the most unpredictable type of commercial lease rent review (it can go up sharply, but sometimes it can go down depending on the lease wording and market conditions).

Market rent reviews usually involve:

• valuation evidence (sometimes from a registered valuer)
• reference to comparable leases and locations
• a negotiation process, with a dispute pathway if you can’t agree

If your lease requires a formal valuation process, make sure you understand who appoints the valuer, who pays, and what information can be considered. These details can make a big difference to the outcome.

2) CPI (Inflation) Rent Review

A CPI review adjusts rent based on the Consumer Price Index. It’s typically more predictable than a market review and tends to track inflation.

However, not all CPI clauses are identical. Some use a base quarter, some apply caps/floors, and some may use a specific index series. Small drafting differences can change the result.

3) Fixed Percentage Or Fixed Amount Increase

Some leases increase rent by a fixed percentage (for example, 3% per annum) or a fixed dollar amount each year.

This can be great for predictability, but it can also be risky if:

• the fixed increase is high compared to realistic revenue growth; or
• the market declines and you’re locked into above-market rent.

4) “The Greater Of” Clauses

Some leases combine methods - for example, rent increases by the greater of CPI or a fixed percentage. These clauses are landlord-friendly because they’re designed to protect against low inflation years.

If you’re signing a lease with a “greater of” clause, it’s worth doing a simple scenario test: what happens to your rent over 3–6 years under different inflation conditions?

5) Rent Review On Renewal

If your lease includes rights of renewal, it may also say rent gets reviewed when you renew (often to market rent). This is important because you might assume renewal equals “same deal, longer time”, but the rent can change significantly at that point.

If you’re considering renewing (or negotiating an extension), it can help to get advice on the lease terms at that point. Depending on what you’re doing, you might be dealing with an Extension Of Lease and rent review terms at the same time.

How Do You Prepare For A Rent Review As A Small Business Tenant?

A rent review doesn’t need to be a nasty surprise. With some planning, you can reduce the risk of a sudden budget blowout and put your business in a stronger negotiating position.

Check The Notice Requirements And Timeframes

Most leases require the landlord to give notice of the review, and they may set deadlines for:

• when the landlord must notify you of the reviewed rent
• when you must object or dispute the proposed rent
• when the new rent takes effect (sometimes backdated to the review date)

Missing a deadline can limit your options. It’s worth diarising rent review dates well in advance and keeping an eye out for notice emails or letters.

Understand The “Total Occupancy Cost” (Not Just Base Rent)

When your rent changes, your outgoings may also change over time. Before you make business decisions (like hiring, expanding, or investing in a fit-out), take a holistic view of your premises costs, including:

• base rent
• operating expenses/outgoings
• car parks, storage, signage fees (if any)
• maintenance obligations and compliance costs

If you’re under pressure from a downturn or unexpected disruption, you may also be negotiating temporary relief. Depending on your situation, a formal Rent Abatement Agreement can help document a short-term reduction or suspension properly (instead of relying on informal emails that might create confusion later).

Gather Market Evidence Early (Especially For Market Reviews)

If the lease provides for a market rent review, it helps to collect evidence before you’re in the middle of a dispute. Useful evidence can include:

• recent leasing deals in your area (similar size, fit-out, foot traffic)
• current vacancy rates (if publicly available)
• any limitations in your premises (access issues, parking, building works, restrictions on use)

This is also where professional valuation evidence can be useful, particularly if the numbers are significant and the lease process expects a valuation-style approach.

Look For Negotiation Levers Beyond Rent

Sometimes you can’t get the rent figure to move much - but you can still improve the overall deal. For example:

• a rent-free period (especially if you’re renewing and committing longer term)
• landlord contribution to fit-out or repairs
• caps on outgoings increases
• more favourable make-good terms
• clarity around permitted use (so your revenue streams are protected)

These are the kinds of items that are often dealt with at the heads of terms stage as well, before final paperwork is signed. If you’re negotiating the commercial terms upfront, a Heads Of Agreement Review can help you spot risk areas before they get locked into the lease.

What If You Don’t Agree With The Rent Review Amount?

Disagreeing with a rent review doesn’t automatically mean you’re stuck. Many leases include a process for negotiation and, if needed, a formal dispute pathway.

What you can do depends heavily on the lease wording, but common options include:

Step 1: Check Whether You Can Object (And By When)

Some leases require you to notify the landlord within a set timeframe if you dispute the reviewed rent. If you miss that window, the lease might treat the landlord’s figure as accepted.

In other words: even if you’re still “thinking about it”, it’s often safer to raise your objection in writing early, then keep negotiating.

Step 2: Follow The Lease’s Review Procedure

A commercial lease rent review clause often sets out a sequence like:

• landlord notifies proposed rent
• tenant disputes / counter-proposes
• parties negotiate in good faith
• if unresolved, an independent expert/valuer is appointed to determine the rent

These processes can be technical. For example, the lease may specify how the valuer is appointed (jointly, by a professional body, or by nomination) and what assumptions must be made about the premises (for example, assuming a “reasonable lease term”).

Step 3: Consider The Commercial Reality

Even if you think the rent is too high, it’s worth weighing up the bigger picture:

• Is the location critical to your revenue (foot traffic, visibility, access)?
• Would relocating cost more than staying (fit-out, downtime, marketing, staff disruption)?
• Are there alternative sites available at a better rate?

Sometimes the best outcome is negotiating the deal so the rent is manageable over time, rather than “winning” a valuation battle.

Step 4: Think Ahead If You Might Sell Or Exit

If you’re planning to sell your business, lease terms can directly affect buyer confidence. A rent spike (or an unpredictable rent review clause) can make your business harder to sell because the buyer can’t forecast costs.

If you’re thinking about transferring the lease to a buyer, the lease may require landlord consent and formal paperwork. That’s where documents like a Deed Of Assignment Of Lease can become part of the transaction process.

Either way, it’s wise to treat rent reviews as part of your long-term business planning - not just a “lease admin” task.

How Do You Protect Yourself Before Signing A Commercial Lease?

The easiest rent review dispute to manage is the one you avoid by getting the clause right upfront.

Before you sign, it’s worth checking:

• How often the rent can be reviewed (annual? every two years?)
• What method applies (market/CPI/fixed/the greater of)
• Whether there are any caps or floors on increases
• Whether rent can ever decrease in a market review (some leases prevent this)
• Who pays for valuers/experts and what happens if there’s a dispute
• Whether rent is backdated to the review date if the process runs late

It can be tempting to treat the lease as a “standard form” document and assume it’s not negotiable. But small changes in the rent review clause can have a huge impact over a 3–6 year period.

If you haven’t signed yet, getting advice on your Commercial Lease Agreement can help you understand where you’ve got room to negotiate, and what terms might cause issues later.

Key Takeaways

• A landlord usually can’t increase rent whenever they want - rent increases are typically limited to what your lease allows and when the lease says a commercial lease rent review can occur.
• Commercial rent reviews in New Zealand commonly occur annually, every 2–3 years, and/or on renewal, but the exact timing depends on your specific lease terms.
• Common rent review methods include market rent reviews, CPI adjustments, fixed increases, and “the greater of” clauses - each has different risk and predictability for your cashflow.
• Preparing early (diarising review dates, understanding notice periods, and gathering market evidence) puts you in a stronger position before a rent increase hits.
• If you disagree with the reviewed rent, your lease may set out a dispute pathway (often involving negotiation and an independent valuation/expert determination), but strict deadlines can apply.
• The best time to manage rent review risk is before you sign - having the rent review clause properly reviewed can protect your business from day one.
