If you’ve been told you missed your renewal window, you’re stuck – that’s not the law.
Three lease mechanisms get used interchangeably by tenants, landlords, agents in a hurry, and the occasional lawyer who should know better. They are not the same thing. The difference between them can be the difference between a routine renegotiation and a six-figure problem you didn’t see coming.
Here is what each one actually does, why the distinction has commercial consequences, and the statutory relief most tenants don’t know exists.
Extension vs renewal – the real distinction
An extension continues the existing lease. Same document, same clauses, same fit-out clock, same make-good obligation. The lease just runs longer. If the extension is built into the original lease as a contractual right, it triggers like any other clause – including any rent review mechanism the extension clause references.
A renewal renews the lease under the renewal mechanism in the original lease. A new term commences, rent resets per the renewal clause – typically to market subject to whatever ratchet, CPI cap, or arbitration mechanism applies – and the renewal-rights count steps down by one.
Both can be contractual. Both can be negotiated. The difference is what happens to the terms when the new period begins.
This sounds academic until you are in the middle of a refinance and the bank wants to know your term certain. A right of renewal that has not been exercised counts for nothing. A signed extension counts in full. Same physical lease, two different bank conversations.
Why the distinction has commercial consequences
WALT. Weighted average lease term, the number every commercial valuer and every institutional buyer looks at first, is calculated on signed term. Unexercised renewals do not count. Signed extensions do. A landlord pushing for an extension before going to market is usually making a WALT decision. It can be relational too: the tenant may want the additional tenure. But the timing is often the giveaway.
Rent review timing. Renewals typically – though not always – carry a market review at the commencement of the new term. That is the ADLS standard, and where the clause specifies a review, it fires on the renewal date whether anyone wants it to or not. Extensions do not have a commencement in the same sense, because they continue the existing lease rather than starting a new term. Whether an extension triggers a review depends on how the extension clause is drafted. Tenants who assume an extension is simply keep going can be caught out if the extension clause was drafted to trigger a review on the extension date.
Make-good and yielding up. Make-good crystallises against the commencement date of the current term – either the original commencement, or, where a renewal has occurred, the renewal date that started the current term. An extension does not create a new commencement, so it does not shift the make-good reference point. Assuming an extension resets the make-good clock is a common mistake and can lead to a surprise bill at end of term. One exception: if a mid-term refurbishment has been carried out and the lease has been varied at that point to deal with fit-out ownership and make-good obligations, the variation itself can reset or rework the make-good baseline. That is a deal-specific outcome driven by what the parties documented, not the date mechanic.
Surviving renewal rights. Take a tenant on a six-plus-three-plus-three lease – six-year initial term with two three-year rights of renewal. At year three the tenant wants certainty out to year nine. Renewing early consumes one of the two renewal rights: the lease runs to year nine, but only one renewal right is left, so the total potential occupation is twelve years. A deed of extension to year nine, by contrast, leaves both renewal rights intact, taking total potential occupation to fifteen years. Same nine years of certainty either way – three years of option value either kept or given up, depending on which mechanism is used.
Break clauses – the easy part to misuse
A break clause is a contractual right, almost always the tenant’s and occasionally mutual, to terminate the lease early at a specified date.
The mechanics are simple. The conditions usually are not. A typical break clause requires notice within a fixed window, payment of any break fee, full compliance with covenants, vacant possession, and no arrears. UK case law is full of break notices that failed on technicalities – carpets not replaced, signage not removed, a few hundred pounds of unpaid service charge.
NZ leases are increasingly importing UK-style break clauses, particularly in larger institutional deals and longer corporate occupier leases. If you have one, treat the conditions like a checklist with a deadline. Most break failures happen because someone assumed substantial compliance was enough. It is not.
The relief tenants don’t know about
This is the part most tenants do not get told.
Under the Property Law Act 2007, sections 261 and 264, a tenant whose landlord refuses to renew can apply to the Court for relief. The Court can order the landlord to enter into the renewal, despite a missed notice date or even a substantive breach.
The Court has very broad discretion and a strong tendency to grant relief where the breach is not subsisting and substantial and can be quickly remedied. Factors weighed include why the tenant failed to give timely notice, whether landlord conduct contributed to the failure, the tenant’s overall compliance history, prejudice to each side, the landlord’s motivations for refusing, and third-party interests like incoming tenants or purchasers.
NZ Courts have granted relief even where the tenant deliberately withheld notice trying to negotiate better terms. In Wendco (NZ) Ltd v LJCTB Trustees Ltd [2017] NZHC 2668 – the Wendy’s NZ franchise operator – the High Court ordered a renewal despite the tenant intentionally delaying notice to seek a rent reduction. The Court weighed factors including the potential loss of staff employment and Wendco’s substantial fit-out investment.
The underlying principle is that landlords should not be able to take commercial advantage of an inadvertent mistake where refusal would be disproportionate. That said, the principle is not a free pass. A subsequent High Court decision signalled that without comparable mitigating factors – employment impact, sunk fit-out cost, disproportionate harm – courts may be less sympathetic where the sole reason for withholding notice was negotiating leverage. The relief is available. The outcome is fact-dependent.
There is one hard deadline. The tenant must apply to the Court within three months of the landlord’s communication refusing to renew. Miss that and the Court cannot help. Pay close attention to the date on the landlord’s refusal letter.
This relief is available even when the lease has expired and the tenant is holding over on a month-to-month periodic tenancy. An unexercised renewal right can be revived when the landlord moves to terminate.
What this means in practice
If you are a tenant who has missed a renewal notice, you have not necessarily lost the site. Remedy any breach, get advice, and move within the three-month window. Time is the thing that kills these claims, not the underlying breach.
If you are a landlord and the tenant missed their notice or has been in breach, do not assume you can re-let or sell with vacant possession. The Court can still require you to renew. Get advice before you list, sign a new tenant, or commit to a buyer who expects vacant possession.
If you are a developer or investor underwriting a deal with leased income, ask whether any of the income depends on unexercised renewal rights and whether those rights have notice deadlines coming up that could be relevant to your hold period. WALT is the easy number. The option mechanics behind it are the real story.
Honest caveats
This piece is general guidance, not specific legal advice. The PLA relief framework is broad but discretionary – outcomes turn on the specific facts, the wording of your lease, and the conduct of both sides. ADLS Sixth Edition leases have particular renewal mechanics that are not universal across all NZ commercial leases. Bespoke and older leases vary.
If you are sitting on a real renewal, extension, or break issue, the framework above is a starting point, not a substitute for advice from someone who has read your lease.
When to get help
The fastest way to lose money on a commercial lease is to assume the words mean what they sound like in everyday English. They do not.
