Subleasing Commercial Premises in New Zealand: Tenant Legal Guide

If you’re running a small business, your premises can make or break your day-to-day operations. But what happens when you’ve signed a commercial lease and your situation changes-maybe you need to downsize, you’re moving locations, or you want to offset rent by bringing in another business?

That’s where a sublease agreement often comes in.

A sublease can be a smart commercial move, but it’s also a legal arrangement with real consequences. If it’s not documented properly (or if your head lease doesn’t allow it), you could end up in a dispute with your landlord, stuck with unexpected costs, or liable for breaches you didn’t cause.

Below, we’ll break down how a sublease agreement works in New Zealand, what to check before you agree to anything, and the practical legal steps you can take to protect your business from day one.

What Is A Sublease Agreement (And How Is It Different From An Assignment)?

A sublease agreement is where the current tenant (you) leases all or part of the premises to another party (the subtenant) for a period of time.

In a typical commercial leasing setup, there are three key players:

• Landlord – owns the property and has the primary lease with you (the “head lease”).
• Tenant / Head Tenant – you, the party named on the main lease.
• Subtenant – the party you allow to occupy the premises under the sublease.

It’s easy to confuse subleasing with assigning a lease, but they’re different-and the legal outcome can be very different too.

Sublease

• You stay the tenant under the head lease.
• You usually remain responsible to the landlord for head lease obligations (even if the subtenant causes the issue).
• You become a “landlord” to the subtenant and need a contract that manages that relationship properly.

Assignment

• You transfer your lease interest to a new tenant.
• The assignee becomes tenant under the head lease (subject to the terms agreed and landlord consent).
• Your ongoing liability depends on the lease wording and the deal negotiated (sometimes you’re released, sometimes not).

If you’re unsure which option suits your situation, getting advice early can prevent expensive mistakes. In many cases, the landlord will have strong preferences and the head lease will dictate what you can do.

If you need help reviewing the head lease terms before you sublet, a Commercial Lease Review can clarify what’s allowed and what your risks are.

Can You Sublease Commercial Premises In NZ?

Sometimes you can. Sometimes you can’t. And sometimes you can, but only if you follow a specific process.

In most commercial leasing arrangements, your right to sublease will be controlled by the head lease. Common approaches include:

• Subleasing is prohibited entirely (rare, but it happens).
• Subleasing is allowed with landlord consent (very common).
• Subleasing is allowed as long as certain conditions are met (e.g. the subtenant meets the landlord’s criteria, the sublease is in an approved form, or rent can’t be discounted).

Even where consent is required, the lease may say:

• the landlord may withhold consent at its discretion (depending on the wording), or that consent can’t be “unreasonably withheld”;
• you must provide certain documents (like financials or references for the subtenant); and
• the landlord can impose conditions (for example, requiring a deed, guarantees, or variations).

Why Getting Consent Matters

If you sublease without required consent, you may be in breach of the head lease. That can lead to:

• a formal breach notice from the landlord;
• termination rights (depending on the lease and the seriousness of the breach);
• costs, disputes, and pressure to remove the subtenant; and
• damage to your commercial relationship with the landlord (which matters when you later need renewals, rent relief, or variations).

Before you sign anything with a subtenant, it’s worth checking your head lease carefully and, where needed, getting the landlord’s consent in writing (and on terms that match what you’re actually agreeing with the subtenant).

If your arrangement involves taking over someone else’s lease instead, you may be dealing with Assigning A Lease rather than a sublease, which comes with its own process and documentation.

Key Legal Issues And Risks In A Sublease Agreement

A sublease can be a great solution for cashflow and flexibility, but it’s not a “set and forget” document. Here are the key legal issues we typically see for NZ businesses.

You Might Still Be Liable Under The Head Lease

This is the big one: even if the subtenant is paying you rent and occupying the premises, you’re usually still on the hook to the landlord.

That means if the subtenant:

• doesn’t pay rent,
• damages the premises,
• breaches use restrictions (e.g. operating an unapproved type of business), or
• causes compliance issues (noise, safety, hazardous materials, etc.),

the landlord will generally pursue you first, because your contract is with them.

Your sublease agreement should be drafted to manage this risk, including clear obligations, remedies, and recovery rights if you have to pay the landlord because of the subtenant’s actions.

The Sublease Must Not Conflict With The Head Lease

Your sublease agreement can’t give the subtenant “more rights” than you have under the head lease.

Practical examples:

• If your head lease restricts trading hours, your sublease should too.
• If your head lease says no signage without approval, your sublease should reflect that.
• If your head lease requires you to maintain insurance, your sublease should set out what the subtenant must do (and what evidence they must provide).

If your sublease doesn’t line up with the head lease, you can end up stuck in the middle-owing obligations to the landlord that your subtenant isn’t contractually required to meet.

Outgoings, Utilities, And Hidden Costs

Many disputes happen because the parties didn’t clearly define who pays what.

A solid sublease agreement should clearly address:

• rent amount and when it’s payable;
• GST (whether rent is plus GST, and invoicing approach-which can depend on GST registration and the specific arrangement; this is general information, not tax advice);
• outgoings (rates, body corporate fees, insurance contributions, common area maintenance, etc.);
• utilities (power, internet, water)-especially if there’s no separate meter;
• cleaning and waste management; and
• repair and maintenance responsibilities.

Even where your subtenant is taking “part” of the premises, you still need a method for allocating shared costs fairly (and a process for reconciling them).

Term, Renewal, And What Happens If The Head Lease Ends

One issue many businesses don’t realise: a sublease is generally dependent on the head lease.

So if your head lease ends (for example, it expires and isn’t renewed, or it’s terminated due to breach), the sublease will often end as well. In some cases, outcomes can vary depending on the lease documents and what the landlord does (for example, whether the landlord agrees to recognise the subtenant), but you shouldn’t assume a subtenant can stay if the head lease ends.

This needs to be handled carefully in the sublease drafting, including:

• the sublease term (and whether it can extend past the head lease term-usually it shouldn’t);
• early termination rights if the head lease ends;
• handover obligations and make-good requirements; and
• what notices must be given, and when.

If you’re negotiating a new site and want flexibility from the start, it may be worth addressing subleasing and sharing arrangements up front in your Commercial Lease Agreement negotiations.

What Should Be Included In A Sublease Agreement?

A good sublease agreement should do more than just set rent. It should protect your business relationship with the landlord, set clear rules for the subtenant, and reduce the chance of disputes.

While every sublease is different, most well-drafted agreements cover the following.

Parties And Premises

• Correct legal names of the head tenant and subtenant.
• A clear description of what area is being subleased (whole premises vs part).
• Plans/diagrams if only part of the premises is being sublet.

Sublease Term And Rent

• Start date, end date, and any options (if permitted).
• Rent amount and payment frequency.
• Rent review method (fixed increases, CPI, market review-if applicable).
• Bond/security and when it can be applied or must be returned.

Permitted Use And Compliance

• What the subtenant is allowed to do from the premises.
• Any restrictions from the head lease that flow down to the subtenant.
• Obligation to comply with laws and obtain licences/consents relevant to their operations.

Repair, Maintenance, And Make-Good

• Who maintains fixtures and fittings.
• Rules around alterations and fit-outs (including landlord approval if required).
• End-of-term make-good requirements (what condition the space must be returned in).

Insurance And Risk Allocation

• What insurance the subtenant must hold (and evidence required).
• Indemnities (who covers losses arising from damage or breach).
• Limitation of liability positions, where appropriate and enforceable.

Default And Termination

• What happens if rent isn’t paid.
• What happens if the subtenant breaches the sublease or causes head lease breach.
• Notice requirements and remedies.
• Rights to recover costs (including legal costs, if agreed).

If you’re working with a sublease template or a quick download, be careful. Subleases need to match your head lease and your premises realities, and that’s where generic templates can fall short.

For many businesses, it makes sense to have a purpose-built Commercial Sublease Agreement prepared so the obligations are clear and enforceable.

Subleasing Part Of A Premises: Practical Issues Small Businesses Should Plan For

Subleasing isn’t always “here are the keys, good luck”. If you’re sharing space (like a back-of-house area, offices, storage, or a corner of a retail store), there are extra operational details you’ll want locked in.

Shared Access And Security

You’ll want to be clear on:

• who can access the premises and at what times;
• alarm codes, keys, swipe cards, and what happens if they’re not returned;
• security responsibilities if there’s shared access.

Health And Safety Responsibilities

Under the Health and Safety at Work Act 2015, businesses have duties to ensure, so far as reasonably practicable, that people aren’t put at risk.

If you have multiple businesses operating from one space, responsibilities can overlap. You’ll want to think about:

• hazard reporting and incident procedures;
• who provides safety equipment and training (if relevant);
• how shared areas are managed (kitchens, hallways, loading bays); and
• contract terms requiring the subtenant to comply with your site rules.

Fit-Outs, Signage, And Brand Presence

Small businesses often rely on signage, customer experience, and layout. If a subtenant is moving in, consider:

• what signage they’re allowed to install (and whether landlord approval is required);
• whether they can display branding externally or only internally;
• what fit-out changes are permitted; and
• who owns fixtures added by the subtenant when they leave.

Privacy And Customer Data

If you’re sharing premises and systems (like Wi-Fi, CCTV, reception, or shared devices), you may also be sharing access to information.

The Privacy Act 2020 applies to how you collect, store, and use personal information. If your business collects customer details (even something as simple as email addresses for bookings), it’s smart to have a Privacy Policy in place and make sure your internal processes match it-especially when third parties operate onsite.

Also, if you have cameras on the premises, consider workplace/customer privacy expectations and make sure you have a clear, lawful reason and appropriate notices in place.

Key Takeaways

• A sublease agreement lets you sublet all or part of your premises, but you’ll usually remain the tenant under the head lease and stay responsible to the landlord.
• Before subleasing, check whether your head lease allows it and whether landlord consent is required, because subleasing without permission can put you in breach.
• Your sublease should align with the head lease (especially around permitted use, signage, fit-outs, and compliance requirements) so you’re not caught between inconsistent obligations.
• A well-drafted sublease agreement should clearly cover rent, outgoings, utilities, maintenance, insurance, term/termination, and what happens if the head lease ends early.
• If you’re sharing a premises, don’t forget practical risk areas like security, shared access, health and safety responsibilities, and how customer information is handled.
• Because subleasing is heavily dependent on your specific lease terms and business setup, getting tailored legal advice can save you time, cost, and major disputes later.
