Subleasing Commercial Premises In New Zealand: Legal Requirements

Outgrowing your space isn’t the only reason a commercial lease stops working. Maybe you’ve expanded online, downsized your team, finished a short-term project, or simply locked in a lease term that no longer matches your cashflow.

In many cases, subleasing commercial premises is a practical solution. You keep your lease (and may avoid the costs and disruption of negotiating an early exit), while bringing in a subtenant to cover some or all of the rent and outgoings.

But subleasing isn’t just a handshake deal. It’s a legal arrangement layered on top of your existing lease, and if it’s not structured properly, you can end up paying for a space you don’t control, dealing with disputes you didn’t anticipate, or breaching your lease with the landlord.

This guide breaks down how subleasing commercial premises works in New Zealand, what you need to check before you do it, and how to set it up so your business is protected from day one.

What Does Subleasing Commercial Premises Actually Mean?

When you sublease, you (the original tenant) grant another party (the subtenant) the right to occupy all or part of the premises for a period of time.

It’s important to understand what doesn’t change:

• You’re still the tenant under the head lease (your lease with the landlord).
• You’re still responsible to the landlord for rent, outgoings and complying with the head lease.
• Your landlord usually still deals with you, not the subtenant (unless the lease allows otherwise).

That’s why the legal risk sits heavily with you. Even if the subtenant pays you late, damages the premises, or breaches the permitted use rules, the landlord may treat it as your breach under the head lease.

Subleasing is also different to a few similar arrangements:

• Assignment: you transfer your lease to a new tenant, and (depending on the terms) you may be released from ongoing liability. This often involves a Deed of Assignment of Lease.
• Licence to occupy: a more flexible permission to use the space (often used for pop-ups, desk sharing, storage, or short-term arrangements). In some situations, a Property Licence Agreement is more appropriate than a sublease.

If you’re not sure which structure fits, it’s worth getting advice early. Picking the wrong structure can create enforcement issues later (for example, you may think you have a “licence”, but legally you’ve granted a lease-like right to occupy).

Can You Sublease Commercial Premises Under Your Lease?

Before you negotiate with anyone, start with your head lease. Most commercial leases have specific rules about subleasing, and it’s common for subleasing to require landlord consent.

Typically, your lease will cover things like:

• Whether subleasing is allowed at all (some leases prohibit it).
• When consent is required (often “prior written consent”).
• Conditions the landlord can impose (e.g. approving the subtenant’s financials, requiring references, requiring a deed, or charging legal costs).
• Use restrictions (the subtenant’s business may need to match the “permitted use” in your lease).
• Signage, fitout, access and hours rules that must still be followed.

If you sublease without following the lease process, you could be in breach. Depending on the wording of your lease and the circumstances, the landlord may be able to issue a breach notice, require you to remedy the issue, recover costs, or take other enforcement steps (and in more serious or unresolved situations, it could ultimately put the lease at risk).

If you’re uncertain about your subleasing rights, getting a Commercial Lease Review before you commit can save you a lot of time (and prevent you from negotiating a deal you can’t legally implement).

Do You Need The Landlord’s Written Consent?

Often, yes. Even where the lease doesn’t outright ban subleasing, it commonly requires written consent.

In practice, landlords usually want comfort that:

• the subtenant is credible and financially stable
• the subtenant’s use won’t create compliance issues (noise, fumes, foot traffic, after-hours access)
• their property won’t be damaged or poorly maintained
• the arrangement won’t reduce their ability to enforce the head lease

It’s also common for a landlord to require you to pay their legal fees for reviewing and documenting consent. Make sure you budget for this from the start.

How Do You Set Up A Sublease? A Practical Step-By-Step

Subleasing commercial premises tends to go smoothly when you treat it like a structured transaction, not a quick fix. Here’s a practical process many small businesses follow.

1. Confirm Your Business Goal (And Your Non-Negotiables)

Start by being clear on what you actually need:

• Do you want to sublease the whole premises or just part?
• Do you still need access (e.g. storage, a back office, shared amenities)?
• Do you need a subtenant aligned with your brand (e.g. a complementary business)?
• Are you trying to reduce costs short-term, or permanently change how you operate?

This matters because the legal structure (and the level of control you keep) should match your operational reality.

2. Check The Head Lease For Restrictions

Look closely at:

• consent process and timeframe
• permitted use
• outgoings and who must pay them
• maintenance and repair obligations
• insurance requirements
• make good / reinstatement obligations at the end of the lease

If your lease is unclear (or you suspect the “standard” wording won’t match what you want to do), it’s worth getting advice before you negotiate. It’s much easier to negotiate with the landlord early than to try to “fix” a sublease after it’s signed.

3. Negotiate Heads Of Agreement With The Subtenant

Before drafting the full sublease, it’s common to agree on the commercial terms first, such as:

• sublease term and any renewal options
• rent amount and payment frequency
• outgoings (included or charged separately)
• bond / security
• fitout permissions
• who pays utilities
• any shared space rules

These terms are often captured in a Heads of Agreement, which helps keep negotiations on track and reduces misunderstandings when the final document is drafted.

4. Obtain Landlord Consent (Before Anyone Moves In)

Don’t let the subtenant take possession (or start paying rent) until you’ve met the consent requirements under the head lease.

In many cases, the landlord may require:

• a copy of the sublease for approval
• information about the subtenant and their business
• evidence of insurance
• a deed or written consent document signed by all parties

If timing is tight, you can still move quickly - but it needs to be done in the right order.

5. Sign A Proper Sublease (Not A Template)

Once you’ve agreed the terms and received consent, the key legal step is documenting the arrangement properly. For most businesses, that means putting a tailored Commercial Sublease Agreement in place.

A well-drafted sublease doesn’t just say “pay rent and use the premises”. It should also align with your head lease, allocate risk clearly, and give you practical enforcement options if something goes wrong.

What Should A Commercial Sublease Agreement Cover?

Because you’re still on the hook under the head lease, the sublease should be drafted to “flow through” the obligations the landlord can enforce against you.

While every sublease is different, these clauses commonly matter the most for small businesses.

Rent, Outgoings And Payment Mechanics

Your sublease should clearly cover:

• the rent amount (and whether GST is included)
• when it’s due and how it’s paid
• late payment interest
• outgoings (rates, insurance, utilities, body corporate fees, maintenance contributions)
• how outgoings are calculated and billed

This is one of the biggest dispute areas in subleasing commercial premises. If the subtenant thinks outgoings were “included” but you intended to pass them on, you can end up wearing the shortfall.

Note: GST treatment can be fact-specific and depends on the arrangement and the parties. This article is general information and isn’t tax advice.

Term, Renewal, And Alignment With The Head Lease

A common trap is offering a sublease term that doesn’t match your head lease term.

In most cases:

• your sublease should end before (or at the same time as) your head lease ends
• any renewal options should be carefully drafted so you’re not promising something you can’t deliver

If you plan to negotiate a renewal with the landlord, keep your subtenant informed - but avoid making guarantees unless the landlord has already agreed.

Permitted Use And Compliance With Laws

Your head lease will usually restrict the “permitted use” of the premises, and that needs to carry through to the subtenant.

You should also consider legal compliance that might impact you as head tenant, such as:

• Health and Safety at Work Act 2015 obligations (particularly if there are shared areas or you retain some control of the premises)
• Fair Trading Act 1986 risks (for example, if you make representations about the premises or its suitability)
• Privacy Act 2020 requirements if you’re handling the subtenant’s personal information (applications, IDs, background checks, contact details)

The key idea: even though the subtenant runs their own business, the arrangement can still create legal and operational exposure for you if it’s not managed properly.

Repairs, Maintenance And “Make Good”

Maintenance and end-of-term reinstatement (“make good”) obligations can be expensive, and they often become a problem when the subtenant has altered the space.

Your sublease should deal with:

• who is responsible for day-to-day maintenance
• what happens if the subtenant causes damage
• who pays for repairs and when
• whether the subtenant must remove fitout and reinstate the premises

Remember: the landlord can enforce the head lease against you, even if the damage was caused by your subtenant.

Insurance And Indemnities

It’s common for the head lease to require certain types of insurance. Your sublease should reflect this, and you’ll usually want the subtenant to carry appropriate cover too.

An indemnity clause can also be critical. Put simply, it’s a contractual promise that if the subtenant’s actions cause you loss (for example, landlord claims, repair costs, or third-party claims), the subtenant must cover that loss.

Default, Termination And Step-In Rights

When subleasing commercial premises, you need practical options if the subtenant:

• doesn’t pay rent
• breaches the permitted use
• damages the premises
• creates issues with neighbours or the landlord

Your sublease should include clear breach notice processes, termination rights, and (where appropriate) rights for you to step in and remedy issues quickly to protect your position under the head lease.

Common Risks With Subleasing (And How To Manage Them)

Subleasing can be a smart move, but it’s not “set and forget”. Here are some common issues we see small businesses run into.

You’re Still Liable To The Landlord

This is the big one. Even if the subtenant is the one occupying the space, the landlord will usually hold you responsible for:

• rent and outgoings
• damage and repairs
• compliance with use and conduct rules
• make good at the end of the head lease

That’s why your sublease needs to be tight, and why you should stay involved enough to ensure the premises are being used properly.

Partial Subleases Create Shared Space Complexity

If you’re subleasing part of your premises (for example, one room, a back warehouse area, or a portion of a retail floor), you should think about “shared space” issues upfront:

• who controls access and keys/alarm codes
• who can use meeting rooms, bathrooms, kitchens and parking
• how utilities are split
• noise, deliveries, security, waste and cleaning responsibilities

If these aren’t clear, you can end up with day-to-day friction that turns into a legal dispute later.

Financial Stress: Rent Abatement And Renegotiation

Sometimes, the reason you’re subleasing commercial premises is financial pressure. If that’s the case, it can be worth considering whether you also need to negotiate with the landlord on rent or other terms.

Depending on your circumstances (and your lease wording), a Rent Abatement Agreement might be relevant - for example, where the premises can’t be used in the usual way for a period of time. This is a specialised area and usually needs tailored advice, because the facts matter.

Due Diligence: Don’t Skip The Basics On Your Subtenant

It’s tempting to accept the first interested party, especially if you’re paying rent on unused space. But you should still do basic checks on the subtenant, such as:

• identity and company details
• creditworthiness and trading history
• references (including prior landlords if possible)
• what business they’ll run and whether it fits the premises

If the sublease is significant (high rent, long term, or a large portion of your premises), a more formal Legal Due Diligence Package can help you spot issues before you commit.

Know When Assignment Is The Better Option

Subleasing is great when you want to retain the lease or return to the premises later. But if you’re exiting permanently, assignment can sometimes be cleaner.

With an assignment (subject to lease terms and landlord consent), the incoming tenant takes over the lease. That process is usually documented through a Deed of Assignment of Lease. Depending on the lease and negotiations, you may be released from some ongoing obligations (though not always).

This is one of those “get advice first” decisions, because the wrong approach can lock you into liability for longer than you expect.

Key Takeaways

• Subleasing commercial premises can reduce costs and keep your business flexible, but it doesn’t remove your obligations under the head lease.
• Always check your head lease for sublease restrictions and whether you need landlord consent before negotiating too far.
• A sublease should align with your head lease, especially around term, permitted use, outgoings, repairs, and make good.
• Use clear written terms (often starting with a Heads of Agreement) and avoid relying on generic templates for the final sublease.
• Do practical due diligence on your subtenant, because if they breach the rules, you may still wear the landlord’s enforcement action.
• If you’re leaving permanently, consider whether an assignment (rather than a sublease) is the better long-term solution.
