Director Guarantees In New Zealand: What Business Owners Should Know

If you run a small business, chances are you’ve been asked (or will be asked) to sign a personal guarantee at some point - often when you’re trying to secure a lease, open a trade account, or get funding.

It can feel like “just paperwork” standing between you and the next step in your business. But director guarantees in New Zealand can create very real personal financial exposure, even if you’ve set your business up as a limited liability company.

In this guide, we’ll walk you through what a director guarantee usually means, when you’re likely to see one, the risks to watch for, and practical ways to negotiate and protect yourself before you sign.

What Is A Director Guarantee (And Why Do Businesses Ask For One)?

A director guarantee (often called a “personal guarantee”) is a promise you make in your personal capacity to pay a business debt or meet a business obligation if your company doesn’t.

Even though your company is a separate legal entity, a guarantee is designed to give the other party extra comfort that they can recover their money if things go wrong.

How A Guarantee Works In Practice

Let’s say your company signs a contract with a supplier on 30-day terms. If the company doesn’t pay, the supplier might be able to:

• chase the company for the debt; and
• if there’s a guarantee, also chase you personally (and sometimes other directors/guarantors) for the same debt.

Many business owners are surprised by how far this can go. A guarantee can sometimes extend beyond a single invoice and apply to:

• ongoing trading accounts (including future orders),
• rent and outgoings under a commercial lease,
• damages, interest, and enforcement costs, and
• other obligations your business agrees to (depending on the document).

Director Guarantee vs “Limited Liability”

A big reason people form companies is to separate business risk from personal risk. But a guarantee can “cut across” that separation.

That doesn’t mean guarantees are always unreasonable - they’re common in the New Zealand market, especially for newer companies. But you should treat them as a major legal and financial decision, not a formality.

If you’re trying to get your overall risk exposure clear, it’s also worth understanding how personal exposure can arise in other ways for directors (not just guarantees), including director duties and other liability issues. This is closely related to Personal Liability Company Director considerations.

When Are Director Guarantees Common In New Zealand?

Director guarantees in New Zealand show up most often when your company is taking on a commitment where the other party is worried about non-payment, or where your company doesn’t have a long trading history.

1) Commercial Leases

Landlords commonly require directors (and sometimes shareholders) to personally guarantee the tenant company’s obligations.

This is especially likely where:

• your company is newly incorporated,
• the lease term is long,
• the premises are specialised (harder for the landlord to re-lease), or
• there are significant fit-out contributions or incentives.

Before signing anything in this space, it’s often worth having the lease and guarantee reviewed together so you can see how the obligations interact. A Commercial Lease Review can be particularly helpful where the “guarantee” is embedded into broader lease documents or drafted as a separate deed.

2) Trade Credit Accounts And Suppliers

It’s very common to see personal guarantees in “credit application” forms, supply terms, or customer onboarding packs - particularly where you’re applying for terms instead of paying upfront.

A common trap is that a director signs a credit application quickly, without realising that:

• the guarantee is continuing (it doesn’t automatically end), and
• it might cover all amounts owing, including interest and collection costs.

3) Equipment Finance, Loans, And Banking Facilities

Lenders often want guarantees, and sometimes also want security over personal assets. Depending on the structure, you may also see business security documents that work alongside a guarantee, such as a General Security Agreement (which can secure business assets, and sometimes sits alongside personal guarantees).

4) Business Purchases Or “Earn-Out” Deals

If you’re buying a business, or entering into a payment plan arrangement, the seller may request a director guarantee to reduce their risk.

Similarly, where there’s an instalment plan or vendor finance arrangement, personal security may be part of the negotiation.

What Are The Biggest Risks With Director Guarantees?

A guarantee is not automatically “bad” - but it’s risky when you don’t understand what you’re signing, or when the drafting is broader than you expect.

Here are the biggest issues we see business owners run into.

1) Unlimited Or “All Monies” Guarantees

Some guarantees aren’t limited to a specific amount. Instead, they cover all money your business owes now or in the future.

That can be hard to control, particularly if:

• multiple staff can order goods/services,
• pricing changes over time, or
• you’re not monitoring credit limits closely.

2) Joint And Several Liability

If multiple people sign as guarantors (for example, two directors), the guarantee may say liability is joint and several.

That typically means the creditor can pursue one guarantor for the whole debt, not just “their share”. You may be able to pursue the other guarantor later, but that can be messy and expensive (especially if relationships have changed).

3) Guarantees That Outlive Your Involvement In The Business

A very common scenario is:

• you sign a guarantee early on,
• years pass,
• you resign as director or sell your shares, and
• the account continues, but your guarantee was never properly released.

So even though you’re no longer “in the business”, you might still be exposed if the company defaults later.

This is why it’s important that when ownership or control changes, you tidy up the legal documents around it (including how guarantees are dealt with). It’s also why strong internal governance documents can matter, like a Shareholders Agreement that sets expectations around approvals, funding, and major commitments.

4) Enforcement Costs, Interest, And Legal Fees

Many guarantees don’t just cover the principal debt. They can also cover:

• default interest,
• collection costs, and
• legal fees on an indemnity basis (meaning you might have to pay more than “standard” costs).

In a worst-case scenario, the “extras” can significantly increase the amount you’re exposed to personally.

5) Set-Off Rights And Security Clauses

Some guarantee documents are packaged with other protections for the creditor, such as:

• the right to combine accounts,
• the right to set-off amounts across different arrangements, or
• charges over assets (in more complex documents).

This is one reason it’s worth having a lawyer read the whole set of documents, not just the page titled “Guarantee”.

Can You Negotiate A Director Guarantee? Practical Options For Small Business Owners

Yes - in many cases, you can negotiate. Whether the other side agrees depends on your bargaining power, the value of the deal, and how risk-averse they are.

But even small changes to a guarantee can make a big difference.

1) Ask For A Cap (Maximum Amount)

One of the most practical protections is a dollar cap (for example, “limited to $20,000”).

This helps you quantify your maximum personal exposure and align it with your actual ability to manage risk.

2) Limit The Guarantee To Specific Obligations

Instead of guaranteeing “all obligations”, you may be able to limit it to:

• rent only (excluding make-good or damages),
• invoices issued within a defined period, or
• a single contract (not future contracts).

3) Time-Limit The Guarantee

A guarantee can sometimes be limited to a period (for example, the first 12 months of trading, or the initial lease term but not renewals).

This can be especially useful where the other party’s main concern is that your business is “new” - once you’ve built a track record, their risk may reduce.

4) Replace Or Supplement With Other Security

Sometimes the other party will accept alternatives, such as:

• a higher bond (in a lease context),
• a bank guarantee,
• personal property security over business assets, or
• payment upfront / shorter payment terms.

These options aren’t always cheaper or easier - but they may reduce the risk of your family home or personal assets being on the line.

5) Get A Release When You Exit

If you’re selling your business, stepping down as a director, or bringing in new owners, make “guarantee release” a specific item on your exit checklist.

It’s not enough to just resign on the Companies Office register. You generally need the creditor/landlord to formally release you (often in writing, and sometimes by deed) and, if required, replace you with a new guarantor.

What Should You Check Before You Sign A Director Guarantee?

This is the part that saves you headaches later. Before you sign, slow down and check what you’re actually agreeing to - because once it’s signed, it can be hard to unwind.

1) Who Is The Guarantor (And Are You Signing The Right Way)?

Make sure the document clearly states:

• your full legal name (not a nickname),
• your address, and
• that you’re signing personally (not just “as director”).

It’s also important to understand whether you’re signing an agreement or a deed, as formalities can differ and the consequences can be serious. This ties into What Makes A Signed Document Legally Binding considerations, especially if the guarantee is being signed quickly as part of onboarding.

2) Is It A Guarantee Only, Or A Guarantee And Indemnity?

You’ll often see “guarantee and indemnity” wording. In plain terms:

• a guarantee is typically a promise to pay if the company doesn’t; and
• an indemnity can create a more direct obligation to compensate for loss, sometimes in broader circumstances.

This difference can affect how easy it is for the other party to enforce against you, and what defences might be available.

In commercial contexts, this is often documented as a deed. If you’re dealing with a formal document of this kind, it may be relevant to use (or review) a Deed Of Guarantee And Indemnity that reflects the actual deal you intended.

3) What Debts And Obligations Are Covered?

Look for clauses that define the “Guaranteed Money” or “Guaranteed Obligations”. Ask yourself:

• Does it cover only invoices, or also interest and legal fees?
• Does it cover damages and “consequential loss”?
• Does it cover future contracts and renewals automatically?
• Does it apply even if the creditor varies the underlying agreement?

Many guarantees allow the creditor to change terms with the company (for example, increasing a credit limit) without needing to notify you personally - and your guarantee may still apply.

4) Are There Any “Demand” Provisions?

Some guarantees allow the creditor to require payment by making a formal demand. In practice, once a valid demand is made, the next steps (and how quickly things can escalate) will depend on the wording of the guarantee and the circumstances.

It’s worth checking:

• how a demand can be served (for example, email, post, or hand delivery), and
• what timeframe applies after a demand is served (if any is specified).

5) Are You Required To Get Independent Legal Advice?

Some lenders and landlords want confirmation you’ve had legal advice, or at least the opportunity to get it. Even if it’s not required, it’s often a smart step - particularly if the amount involved is significant.

It can also help protect you from later disputes about what you understood when signing.

6) Does It Need To Be Witnessed (And If So, By Who)?

Some guarantees (particularly if they are drafted as deeds) have specific signing requirements, which may include witnessing. The rules can vary depending on the document and context, so it’s important to get this right before you sign.

If witnessing is required, make sure the witness is eligible and the signing process is done correctly. This is where Who Can Witness A Signature becomes practically important - because problems with execution can create delays and disputes later.

7) Consider The “Worst Case” Scenario Before You Commit

This isn’t about being pessimistic - it’s about being prepared.

Ask yourself:

• If the business failed, could I pay this personally without losing key assets?
• Am I comfortable with the risk given the upside of the deal?
• Do I need to restructure the deal (cap, time-limit, alternative security)?

It’s also a good moment to review your internal decision-making and governance. For example, if you’re in business with others, you may want rules about when guarantees can be signed and who must approve them, which can be supported by a tailored Company Constitution.
