Do You Inherit Debt When Buying A Business In New Zealand?

Buying an existing business can be a great shortcut to revenue, systems, staff and a customer base - but it also comes with a big question most buyers don’t want to ask out loud:

Are you taking on someone else’s debt?

This is where concerns about debt liability when buying a business become very real (and very practical). The good news is that in New Zealand, you don’t automatically “inherit” all business debt just because you buy a business.

But the not-so-good news is that you can end up exposed to liabilities if you buy the wrong way, don’t do proper due diligence, or sign a contract that shifts risk onto you.

Below, we’ll walk you through how debt and liability can work when buying a business in NZ, the key differences between an asset sale and a share sale, what to look for in due diligence, and the contract protections that can help keep you safe.

Do You Automatically Inherit Debt When Buying A Business?

Usually, no - but it depends on what you’re buying and how the deal is structured.

When people talk about “buying a business”, they often mean one of two things:

• Asset sale: you buy the business assets (stock, equipment, IP, customer lists, goodwill), and you typically don’t take over the seller’s company itself.
• Share sale: you buy the shares in the company that owns the business, meaning you effectively “step into” ownership of that same company.

That structure matters because debt and liability generally “live” with the legal entity that incurred them.

So, if you buy assets, you can often avoid taking on historical debts (unless you agree otherwise). If you buy shares, you are buying the entity that already has those debts and obligations - even if you didn’t cause them.

In other words, the risk of debt liability when buying a business is generally higher in share sales unless the contract and due diligence are done properly.

Asset Sale Vs Share Sale: Which One Exposes You To Debt?

This is one of the first things you should get clear on before you negotiate a price.

Asset Sale (Usually Lower Debt Risk)

In an asset sale, you purchase selected assets from the seller. The seller keeps their company (or sole trader structure), and you usually start running the business using your own structure.

In many cases, the contract will specify that:

• the seller pays out their existing liabilities (such as trade creditors) up to completion; and
• you’re not taking on their historical debts unless explicitly listed.

That said, an asset sale isn’t a “magic shield”. You can still end up with liability risks if:

• you agree to take on certain contracts (like a lease, supplier agreement, finance agreement);
• you purchase stock or equipment subject to security interests; or
• there are employee-related obligations that carry over in practice (more on this below).

Typically, you’d document the deal clearly in an Business Sale Agreement so it’s obvious what you are and are not assuming.

Share Sale (Higher Debt Risk)

In a share sale, you buy the company itself (by buying its shares). The company remains the same legal entity - you’re just changing who owns it.

That means the company still has:

• its loans and liabilities,
• its tax history,
• its contracts,
• its employment obligations, and
• potentially unknown claims (for example, disputes, warranty claims, or investigations).

You can manage these risks with the right warranties, indemnities and due diligence, but this is where buyers can get caught out if they rely on high-level summaries without verifying what sits underneath.

Common Debts And Liabilities Buyers Get Stuck With (Even If They Didn’t Expect To)

When we talk about “debt”, most people think of a bank loan. But in business purchases, “liability” is broader - and some liabilities are not obvious until after settlement.

Here are some of the more common ones to watch for.

1) Loans, Finance Agreements And Personal Guarantees

If the seller has business loans, hire purchase, or equipment finance, check:

• who the borrower is (the seller personally or the company),
• whether the loan is secured against business assets, and
• whether the seller has given personal guarantees (and whether the lender will release them).

If you’re buying assets, you’ll usually want the seller to pay out and discharge finance before completion - otherwise the lender may have rights over the assets you think you’re buying.

2) Security Interests Over Assets (PPSR Issues)

In NZ, lenders and suppliers can register security interests over business assets. If you buy equipment or stock that’s subject to a registered security interest, you can end up in a messy dispute about who owns what.

This is one of the reasons legal due diligence matters even for “simple” purchases.

3) Tax Liabilities (GST, PAYE And Income Tax)

Tax is a big area where buyers can underestimate risk, especially in share sales.

Examples include:

• unpaid GST returns,
• PAYE issues (including payroll errors),
• late filing penalties and interest, and
• historical tax positions that may be challenged later.

You’ll usually want your accountant involved here, and this article isn’t tax advice. As part of the legal side, your sale documents should also allocate risk properly (for example, by requiring the seller to warrant that tax filings are up to date and providing protections if a pre-completion tax issue arises).

4) Employment Liabilities And Staff Entitlements

If the business has staff, liabilities can include:

• outstanding holiday pay and other leave entitlements,
• unresolved personal grievances,
• underpayment claims (minimum wage, overtime, public holiday rates), and
• contracting arrangements that are actually employment in disguise.

Even in an asset sale, employees may transfer to the buyer in certain situations (for example, if the business is being sold as a going concern), and some categories of employees have special protections. Exactly what carries over (and who pays what) can be fact-specific, so you’ll want to be very clear in the sale documentation about accrued entitlements and responsibility for any pre-completion issues.

If you’re onboarding staff after completion, having proper Employment Contract documentation (and a plan for transfer/continuity) can help avoid confusion from day one.

5) Lease Obligations

If the business operates from commercial premises, the lease is often one of the largest ongoing liabilities.

Key questions include:

• Are you taking an assignment of the existing lease, or signing a new one?
• Are there arrears (rent, outgoings) owing?
• Are there upcoming rent reviews or renewal deadlines?
• Are there make-good obligations at the end of the term?

It’s common for buyers to have a Commercial Lease Review done alongside the business purchase so there are no surprises after settlement.

6) Customer Claims And Consumer Law Exposure

If you’re buying a consumer-facing business (retail, services, e-commerce), you should assume there’s ongoing exposure under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986.

Sometimes complaints relate to sales made before you took over. Whether the seller remains responsible, or the ongoing business (and therefore you) ends up having to handle the claim, can depend on how the sale is structured, what representations were made, and what the sale agreement says about pre-completion conduct and claims. This is why it’s important to address pre-completion customer issues clearly in the contract.

How Do You Protect Yourself From Debt Liability When Buying A Business?

You can’t eliminate all risk, but you can reduce it dramatically with the right approach before you sign anything.

1) Choose The Right Deal Structure (Don’t Skip This Step)

Many buyers focus on price first. But the structure determines your risk profile.

• If you want to minimise historical liabilities, an asset sale is often preferred.
• If you need to keep contracts, licences, brand history, or the company structure itself, a share sale may be necessary - but you’ll need stronger protections.

There isn’t a one-size-fits-all answer. A lawyer can help you compare risk and practicality before you commit to a structure.

2) Do Proper Legal Due Diligence

Due diligence is where you verify what you’re actually buying - not just what the seller says you’re buying.

Legal due diligence commonly involves reviewing things like:

• key customer and supplier contracts,
• lease documents and any side letters,
• finance documents and securities,
• employment agreements and policies,
• intellectual property ownership (brands, domains, software),
• pending disputes, claims, or notices, and
• privacy/data practices if customer information is part of the deal.

If you’re purchasing a business with online operations or customer databases, your compliance under the Privacy Act 2020 matters too - and a fit-for-purpose Privacy Policy is often part of operating safely going forward.

Where the purchase is significant (or the risk is higher), a structured Legal Due Diligence Package can help you get visibility before you sign.

3) Make Sure The Sale Agreement Allocates Liability Clearly

The sale agreement is where you set the rules for who carries which risk - especially for liabilities that relate to the “before” period.

Some key protections often include:

• Warranties: promises by the seller about the state of the business (for example, that accounts are accurate, taxes are up to date, there are no undisclosed liabilities).
• Indemnities: the seller agrees to reimburse you if a specific risk event happens (for example, if a pre-completion tax debt is assessed later).
• Completion accounts or adjustments: mechanisms to adjust the price depending on stock levels, debtors, creditors, or working capital at completion.
• Conditions precedent: requirements that must be met before the deal completes (like landlord consent, finance approval, or the discharge of a loan).

This is one of the biggest “don’t DIY” moments. Generic templates can miss the exact scenario you’re walking into, and that’s how buyers can end up paying for someone else’s mistakes.

If you already have a draft agreement from the seller (or broker), it can be worth having a Business Sale Agreement Review so you understand what liability you’re accepting before you sign.

4) Be Careful With “Taking Over” Contracts

Sometimes what looks like a simple business purchase is actually a bundle of contract transfers.

For example, you might be “taking over”:

• a lease,
• a supplier agreement with minimum purchase obligations,
• a service contract with performance KPIs, or
• a software subscription with auto-renewal fees.

If these aren’t reviewed carefully, you can end up locked into terms that don’t suit your plans - or inheriting obligations that feel like “debt” in practice (because they cost you money, regardless of revenue).

What Should A Buyer Ask Before Signing Anything?

If you’re early in the process, these are some practical questions to raise. They’ll help you surface risk and guide what you should check in due diligence.

• Am I buying assets or shares? (And do I understand what that means for debt?)
• Is there any finance over plant, equipment or vehicles?
• Are there any unpaid creditors or disputed invoices?
• Are there any pending legal claims or customer disputes?
• Are all tax filings up to date? (Have my accountant and lawyer verified this?)
• What employee entitlements are owing, and who will pay them?
• Is the lease being assigned, and are there any arrears or upcoming rent reviews?
• What contracts are essential to keep the business running?
• What happens if a “pre-sale” issue comes up after completion?

If you’re not sure which questions apply to your situation, that’s normal. A good rule of thumb is: if a business relies on it to operate, it should be reviewed and documented properly.

Key Takeaways

• In New Zealand, you don’t always inherit business debt automatically - but the risk of debt liability when buying a business depends heavily on whether the deal is an asset sale or a share sale.
• In an asset sale, you usually avoid historical debts (unless you agree to assume them), but you still need to check finance, security interests, and contract transfers carefully.
• In a share sale, you’re buying the company that incurred the debts and obligations, so hidden liabilities can follow you unless the deal is properly protected.
• Liability isn’t just “loans” - it can include tax issues, employee entitlements, lease obligations, supplier contracts, and customer claims under the Consumer Guarantees Act and Fair Trading Act.
• Strong due diligence and a well-drafted sale agreement (with warranties and indemnities) are practical ways to reduce your risk before settlement.
• Having key documents reviewed early - especially the business sale agreement and the lease - can save you from costly surprises after you take over.
