Commercial Tenant Rights Without A Written Lease In New Zealand

Signing a commercial lease is one of those “grown-up business” moments - but in the real world, plenty of small businesses start trading in a premises before the paperwork is finished (or sometimes without any paperwork at all).

Maybe you took over a friend’s space, you’re subleasing informally, you moved in while the landlord “gets the lease drafted”, or you’ve been paying rent month-to-month without anyone pushing to document things properly.

If that’s you, it’s normal to feel a bit exposed. And you’re not imagining it: operating without a written lease can create uncertainty around rent, repairs, access, termination, and what happens if the landlord wants you out.

In this guide, we’ll walk you through what commercial tenants’ rights can look like without a written lease in New Zealand, what protections you may still have, and what practical steps you should take to protect your business from day one.

Note: This article is general information only and isn’t legal advice. Your rights can depend heavily on whether your arrangement is legally a lease or a licence, the length/terms agreed, and what evidence exists.

Is A Commercial Lease Valid Without Being In Writing?

Sometimes - but it depends on the type and length of arrangement.

In New Zealand, agreements creating an interest in land (including many leases) often need to comply with formal requirements to be enforceable. In particular, a lease (or agreement to lease) for a longer term will generally need to be in writing and signed to be reliably enforceable, whereas shorter or more informal arrangements may operate in practice as a periodic tenancy or licence.

In practice, you might have:

• An oral (verbal) arrangement - where you and the landlord agreed key points in conversation (rent, what area you occupy, etc). Depending on the circumstances (including duration), it may be difficult to enforce as a “lease” in the way you expect.
• An implied tenancy - where your conduct creates a tenancy relationship (for example, you occupy the premises and pay rent, and the landlord accepts it). This is often treated as a periodic tenancy (eg month-to-month) if there’s no clear fixed term.
• A licence to occupy - which is different from a lease and usually gives you weaker “security of tenure” (it can look like a lease in everyday life, but legally it’s not always treated the same way).

The tricky part isn’t whether something exists - it’s what exactly exists, and what terms apply when something goes wrong.

Without a written lease, you lose the clarity of agreed terms. That can make it harder to prove things like:

• how long you can stay
• how much rent can be increased (and when)
• who pays for repairs and maintenance
• who insures what
• what rights you have to signage, parking, storage, after-hours access, or exclusive areas
• how the arrangement ends (and what notice must be given)

That’s why, even if you’re currently “fine”, it’s usually worth getting the arrangement documented properly - whether that’s a formal lease or another arrangement that reflects what you’ve agreed.

If you’re already looking at paperwork from a landlord (or you’ve been asked to sign something quickly), it’s often worth getting a Lease Review so you’re not locking your business into terms that don’t match how you operate.

What Rights Might You Still Have As A Commercial Tenant Without A Written Lease?

Even without a written lease, you may still have protections - particularly if you can show there is a tenancy relationship (not just a licence) and you have evidence of what was agreed.

1) The Right To Occupy (For Now)

If you’ve moved in, you’re paying rent, and the landlord is accepting it, you’ll often have at least a basic right to occupy - but it may be a periodic tenancy (for example, month-to-month), rather than a secure long-term lease.

That means you can often run your business day-to-day, but your “security” depends on what notice is required to end the arrangement (which may be unclear without written terms, and may also depend on whether the arrangement is legally a lease or a licence).

2) The Right To Quiet Enjoyment (Often, But Not Always)

“Quiet enjoyment” is a core lease concept. In plain English, it means you should be able to use the premises for your business without unreasonable interference from the landlord.

However, the strength of this protection can depend on what your arrangement legally is. If you have a true lease (even if not fully documented), quiet enjoyment is commonly treated as an important tenant protection. If you have a licence to occupy, the same tenant-style rights may not apply in the same way.

Examples of potential issues include:

• landlord entering the premises frequently without notice
• landlord disrupting your trading hours
• landlord cutting off access to parts of the property you’ve been using

Where disputes arise, what matters is often evidence: what was agreed, what has been the practice to date, what rights your arrangement actually grants, and what is “reasonable” in the circumstances.

3) The Right To Enforce Some Agreed Terms (If You Can Prove Them)

If you and the landlord agreed to certain terms (even verbally), those terms may still be enforceable - but the key challenge is proof (and for longer-term deals, enforceability may be limited without a signed written agreement, unless an exception applies).

Helpful evidence can include:

• emails, texts, or messages discussing rent and conditions
• invoices and receipts for rent payments
• bank statements showing consistent rent amounts and dates
• any heads of agreement or draft lease versions
• photos and records showing the area you were allowed to occupy

If you do have a written “summary” document (even if it’s not the final lease), it might function as a Commercial Tenancy Agreement or at least strong evidence of the arrangement.

4) Potential Protections Under General Contract And Property Principles

Even if your arrangement is messy, you may have protections through general principles of contract law and property law - particularly where one party has relied on promises and acted to their detriment (for example, you spent money fitting out the premises based on an agreed term). In limited cases, this can support equitable remedies even where a longer-term lease wasn’t properly documented.

That said, these disputes can become expensive quickly. It’s far better (and cheaper) to document the deal early than to argue about it later.

What Are The Biggest Risks Of Renting Commercial Premises Without A Written Lease?

When people look up commercial tenant rights without a written lease, it’s usually because something has started to go wrong - a rent increase, a dispute about repairs, or a sudden request to leave.

Here are some of the biggest risks we see for small businesses operating without a written lease.

Unclear Term And Termination Rights

If you don’t have a defined lease term (for example, 3 years with renewal rights), you may be treated as having a periodic arrangement.

That can leave you vulnerable if:

• your landlord decides to sell
• the landlord wants the space back
• another tenant offers higher rent

Without clear written notice requirements, disagreements can arise around how quickly you must vacate - and whether the landlord’s conduct is lawful (and, again, whether your arrangement is a lease or a licence can be critical).

Rent Increases And Additional Charges

A written lease usually spells out:

• base rent
• when rent can be reviewed (and how)
• outgoings (like rates, insurance, body corporate levies)
• utilities and shared costs

Without that, you may face surprise costs, or a landlord may attempt to change the deal mid-stream.

Repairs, Maintenance, And Fit-Out Disputes

One of the most common “no lease” disputes is: who pays to fix things?

Examples include:

• air conditioning repairs
• leaking roof
• electrical issues
• plumbing failures
• shopfront glass damage

With no written lease, you may end up paying for items you assumed were the landlord’s responsibility - or the landlord may refuse to act quickly, impacting your ability to trade.

Insurance Gaps

A properly drafted lease will usually allocate insurance responsibilities, and may require you to hold specific cover (like public liability) while the landlord insures the building.

If you’re operating without documentation, there’s a real risk that:

• you’re underinsured
• you assume the landlord has cover they don’t actually have
• there’s no clear process if there’s damage, theft, or a major incident

Difficulty Selling Your Business

If your business is tied to its location (think hospitality, retail, studios, health clinics), a buyer will often ask: “What’s the lease?”

If there isn’t one, it can make a sale much harder - and can reduce the value of what you’ve built, because the buyer can’t be confident they’ll be able to stay in the premises.

This often becomes a key issue during a Legal Due Diligence process.

What Should You Do If You’re Already Trading Without A Written Lease?

If you’re currently in the space and things are “okay”, that’s the best time to tidy this up - before a dispute forces everyone into defensive mode.

Step 1: Gather Your Evidence Of The Arrangement

Start by pulling together:

• bank statements showing rent payments
• emails/texts about rent, outgoings, term, access, and repairs
• any draft lease or heads of agreement
• photos or plans showing what part of the premises you occupy
• invoices/receipts for any fit-out (especially if the landlord agreed to contribute)

This evidence helps clarify what deal has actually been operating in practice.

Step 2: Confirm The Basics In Writing (Even Before A Full Lease)

If a full lease will take time, a short interim document can still reduce risk. At a minimum, you want clear written confirmation on:

• who the parties are (and the correct legal names)
• the premises (what area is included)
• rent amount and payment frequency
• outgoings and utilities
• term (or at least notice required to end the arrangement)
• repair and maintenance responsibilities
• insurance expectations

This can be a stepping stone toward a more formal lease arrangement later.

Step 3: Be Careful About “Informal” Variations

Even when you do eventually sign a lease, many disputes come from side-promises like:

• “We’ll definitely renew you for another 3 years.”
• “Don’t worry about that rent review.”
• “You can use that storage room too.”

If it matters to your business, get it written into the lease or documented properly as an agreed variation.

If you need changes to a lease (or you’re negotiating different terms), it may be better handled through a formal Contract Amendment approach, depending on what stage you’re at and what documents exist already.

Step 4: Consider Whether You’re Actually In A Sublease Or Shared Space Arrangement

Sometimes you’re not dealing directly with the landlord - you might be paying another business to occupy part of their premises.

In that case, you may need a sublease or a clear occupancy arrangement that reflects the real relationship. If a document does exist (or is being proposed), a Commercial Sublease Review can help you understand what you’re signing up to.

Step 5: Get Advice Before You’re Forced To Make A Fast Decision

The most stressful lease problems happen when you’re suddenly told:

• rent is increasing next week
• you need to vacate in 14 days
• you must pay for major repairs immediately

At that point, you’re negotiating under pressure - and that’s rarely where you get the best outcome.

Getting advice early (while you still have options) usually saves time, money, and disruption.

How Can You Protect Your Business Going Forward?

Once you understand your current position, the goal is to get you protected from day one going forward - ideally with a written lease that matches how your business actually runs.

Have A Proper Written Lease (Or The Right Alternative)

A well-drafted commercial lease can clarify the terms that matter most, including:

• lease term and renewals
• rent review mechanisms
• outgoings and operating costs
• repair and maintenance allocation
• make-good obligations at the end of the lease
• permitted use (so you’re allowed to operate your business type)
• assignment rights if you sell your business

If you’re being offered a lease, getting it checked before you sign is one of the simplest ways to avoid nasty surprises later. If you’re negotiating from scratch, you may need help with a Commercial Lease that properly reflects the deal.

Document Any Assignment Or Transfer Properly

If you’ve taken over a premises from another business (or you’re stepping into an existing lease arrangement), it’s important that the transfer is documented properly - otherwise you might be operating in a grey area.

This is often handled through a Deed of Assignment of Lease, which helps formalise who is responsible for what going forward.

Think Ahead To Growth, Renovations, And Selling

It’s easy to focus on “can I just get the keys and start trading?” - but the lease terms you lock in now can shape your options later.

For example:

• If your business takes off, can you extend hours or add signage?
• If you need renovations, do you need landlord consent?
• If you want to sell, can the lease be assigned to a buyer?
• If you want to exit early, what are the break rights (if any)?

A lease should support your business plan, not block it.

Key Takeaways

• It’s possible to occupy commercial premises without a written lease, but longer-term lease arrangements generally need to be in writing and signed to be reliably enforceable, and the lack of documentation can make rights and obligations unclear and harder to enforce.
• Even without a written lease, you may still have protections based on what was agreed (and what can be proven), but this can differ significantly if the arrangement is a licence rather than a lease.
• The biggest risks for commercial tenants without a written lease include uncertain termination/notice, rent increases, disputes over repairs and insurance, and difficulties selling the business.
• If you’re already trading without a written lease, gather evidence of the arrangement, confirm the key terms in writing as soon as possible, and avoid relying on side-promises that aren’t documented.
• The best way to protect your business is to put a proper written lease (or the right alternative arrangement) in place early, so your rent, repairs, renewals, and exit options are clear.
