Share Sale vs Asset Sale: What’s The Best Path When Buying A Business? (2026 Updated)

Buying a business is exciting - you’re stepping into something that already has customers, systems, and (hopefully) steady revenue.

But there’s one decision that can quietly shape your risk, your paperwork, and your tax outcomes: are you buying the shares in the company (a share sale), or are you buying the assets the business uses (an asset sale)?

This is one of those “get it right from day one” choices. The structure you choose affects what you actually own on settlement day, what liabilities you might inherit, and how easy (or painful) the handover is. This updated guide reflects current expectations around due diligence, privacy/data issues, and practical deal structuring that NZ buyers are facing right now.

Let’s break it down in plain English.

What’s The Difference Between A Share Sale And An Asset Sale?

At a high level, the difference is about what you buy.

What Is A Share Sale?

In a share sale, you buy the shares in the company that owns the business.

That means:

• You take over the company itself (the legal entity).
• The company continues to own its assets (equipment, stock, IP, contracts, etc.).
• The company continues to owe its debts and remain responsible for its obligations - even if those obligations arose before you bought it.

It’s common where the business has valuable contracts that are hard to transfer, licences that sit with the company, or a structure that the seller wants to preserve.

What Is An Asset Sale?

In an asset sale, you buy specific assets used in the business (and sometimes take on specific liabilities), but you don’t buy the company itself.

That means:

• You (or your company) purchase a list of assets: plant/equipment, stock, website, IP, customer lists, goodwill, etc.
• You can often choose which liabilities (if any) you’re taking on.
• The seller keeps their company and anything not sold.

This approach is often used when you want a cleaner “start” and to avoid inheriting historical issues - but it can involve more transfer paperwork.

Why This Choice Matters In NZ

In New Zealand, the legal structure you pick doesn’t just change the contract headings - it changes how risk is allocated and what you need to check in due diligence.

For example, in a share sale, you’re effectively stepping into the company’s shoes. In an asset sale, you’re more likely to be building your own shoes and choosing what goes inside them.

Which Option Gives You Better Liability Protection?

Most buyers worry about the same thing: “Am I going to inherit a problem I didn’t cause?”

That’s a smart question, and it’s usually where share sale vs asset sale decisions start.

Share Sale: You Inherit The Company’s Past (Unless You Manage It)

When you buy shares, the company’s history comes with it. This can include:

• unpaid tax or GST issues
• employee disputes or underpayment risk
• customer complaints and warranty obligations
• supplier disputes and contractual liabilities
• privacy/data compliance issues (especially if customer data has been collected informally)

You can still manage these risks - typically through strong warranties/indemnities in the sale agreement and thorough legal due diligence - but you can’t pretend the history doesn’t exist.

It’s also worth remembering directors’ duties and governance don’t magically disappear after settlement. If you’re stepping in as a director, you’ll want to understand your ongoing obligations and exposure, including personal liability risks that can arise in certain situations.

Asset Sale: Often Cleaner, But Not “Risk-Free”

An asset sale usually lets you ring-fence what you’re buying. You can often avoid taking on unknown debts because you’re not buying the entity that owes them.

However, you still need to be careful about:

• employee transfer issues (you may still be taking on staff, and there are rules around continuity and process)
• consumer obligations that attach to goods/services you continue to supply (particularly if you continue a warranty or service model)
• leases and contracts that may need landlord/third-party consent to transfer
• misleading representations - if the seller has oversold performance, you may have remedies, but it’s better to prevent the mess upfront

If you’re relying on what the seller told you during negotiations, it’s important to understand the risk around misrepresentation and why your sale documents should line up with reality.

A Practical Way To Think About It

If you buy shares, you’re buying a container (the company) with everything in it - good and bad.

If you buy assets, you’re choosing what items to buy from the container.

There’s no universal “best” option. The best path depends on what you’re buying, how the business is run, and what risks you’re willing (or not willing) to take on.

How Do Contracts, Leases, And Licences Affect The Deal Structure?

This is where theory meets reality. Even if an asset sale looks safer on paper, it can become complicated if the business relies heavily on contracts that can’t be transferred easily.

Commercial Leases: Assignment And Landlord Consent

If the business operates from premises, a lease is often central to the deal.

In an asset sale, you’ll usually need an assignment of the lease (and the landlord’s consent). That means timing, paperwork, and negotiations about ongoing guarantees or bond requirements.

In a share sale, the tenant (the company) often stays exactly the same - so the lease may continue without a formal assignment. That can be a big practical advantage.

Still, you’ll want to review the lease carefully either way, because change-of-control clauses and consent requirements can still exist. A Commercial Lease Review can flag hidden deal-breakers like personal guarantees, make-good obligations, rent review mechanics, and permitted use restrictions.

Supplier And Customer Contracts: Do They Automatically Transfer?

In an asset sale, contracts typically don’t “automatically” move over - you may need:

• a contract assignment (if the contract allows it), or
• a novation (a new contract replacing the old one, with all parties agreeing).

In a share sale, the company remains the contracting party, so the contracts often continue with minimal disruption.

If the business depends on a small number of key supplier/customer agreements, that can push you toward a share sale - but you’ll still want to check what those contracts say about change of control, termination rights, pricing resets, exclusivity, and restraints.

Licences, Permits, And “Hard-To-Move” Operating Requirements

Some industries have permissions, registrations, or operational arrangements that are easier to keep intact inside the same company.

That doesn’t mean you must do a share sale - but it does mean you should identify early:

• what approvals are required to operate
• who holds those approvals (individual vs company)
• what must happen after settlement to remain compliant

If you’re not sure what exactly you’re “inheriting”, due diligence is where you find out.

What Should You Look For In Due Diligence (And Why It Changes Between Deal Types)?

Due diligence is your chance to confirm that the business is what it claims to be - financially, operationally, and legally.

And yes, it can feel overwhelming. But it’s far less painful than discovering after settlement that the business has missing contracts, tax issues, or a dispute simmering in the background.

Share Sale Due Diligence: Think “Whole Company Health Check”

Because you’re buying the entity, due diligence usually goes wider. Common focus areas include:

• Company structure and governance: share register, constitution, director resolutions, shareholder approvals
• Financial and tax: GST/PAYE filings, debts, aged receivables, lending, guarantees
• Employment: wages, leave, disputes, contractor vs employee risk, restraint clauses
• Key contracts: suppliers, customers, partnerships, software subscriptions
• Compliance and disputes: threatened claims, regulator issues, insurance cover
• Privacy and data: how customer data is collected/stored, marketing consent, security measures

If the business holds valuable customer data (especially if it’s in a CRM, email list, or subscription model), you’ll want comfort that it’s being handled consistently with the Privacy Act 2020. That’s also where a properly tailored Privacy Policy can be part of demonstrating the business has been taking compliance seriously.

Asset Sale Due Diligence: “Are We Getting What We Think We’re Getting?”

Asset sale due diligence is often more targeted, but it still needs to be thorough. You’ll want to confirm:

• the seller actually owns the assets being sold (and they’re not encumbered)
• what’s included and excluded (stock, vehicles, tools, IP, domain names, customer lists)
• what contracts will be assigned/novated (and whether third-party consents are needed)
• what liabilities you’re taking on (if any)

A key document here is an Asset Sale Agreement, because the “shopping list” of what’s being sold needs to be crystal clear. Ambiguity is where disputes love to start.

Don’t Skip IP Checks (Even For Small Businesses)

Even if you’re buying a small business, its brand can be one of the most valuable assets - sometimes more valuable than equipment.

In either deal type, check:

• who owns the domain name(s) and social media handles
• who owns the logo, website content, photography, and marketing materials
• whether the brand name is trade marked (or if it infringes someone else’s mark)
• what software licences or third-party tools are used to operate

If IP ownership isn’t clear, you can end up paying for a business you can’t properly run under its existing brand.

How Do Staff, Customers, And “Goodwill” Work In Each Sale Type?

When you buy a business, you’re not just buying objects - you’re buying relationships and reputation.

That’s often bundled into the idea of goodwill (things like customer loyalty, brand reputation, recurring revenue, and systems).

What Happens To Employees?

Employees are often one of the biggest operational risks in a business purchase - not because people are the problem, but because employment obligations can be complex if they haven’t been handled properly.

In a share sale:

• The employer (the company) stays the same, so employees typically remain employed without needing new contracts.
• You still inherit employment risks within the company (for example, underpayment or unresolved grievances).

In an asset sale:

• You may offer new employment to staff, or transfer them across depending on the structure and agreements.
• You need to plan the transition carefully so you don’t accidentally create disputes or operational disruption.

Either way, it’s a good time to review whether you’ll need updated Employment Contract templates, especially if you’re changing roles, hours, commission structures, or workplace policies after settlement.

What About Customers, Warranties, And Ongoing Service Obligations?

Customers don’t always care about your deal structure - they just want the business to keep delivering what it promised.

If the business sells products or services to consumers, you’ll want to understand how consumer protections apply, including obligations around refunds, quality, and representations under the Consumer Guarantees Act 1993 and Fair Trading Act 1986.

Also think about:

• outstanding prepaid services, memberships, or gift vouchers
• open orders and deposits
• existing warranty commitments
• current disputes and negative reviews (and how they’re being handled)

Goodwill Is Real - But It Needs To Be Protected In Writing

Goodwill is often the reason you’re buying a business instead of starting from scratch. But goodwill can evaporate if the handover is messy or the seller starts competing immediately.

That’s why sale documents often include clauses around:

• restraints of trade (non-competes)
• handover and training periods
• introductions to key clients/suppliers
• announcements and branding transition plans

These need to be tailored - generic templates can miss key practical points that matter to your industry and the way the business actually operates.

Key Takeaways

• A share sale means you buy the company that owns the business, which can be simpler for keeping contracts and leases in place, but it can also mean inheriting historical liabilities.
• An asset sale lets you choose what you’re buying (and often what you’re not), which can reduce legacy risk, but it may require more work to transfer leases, contracts, IP, and operational arrangements.
• Due diligence is critical in both structures, but it’s usually broader in a share sale because you’re taking over the whole entity, including tax, employment, and compliance history.
• Leases and key contracts often influence the “best” structure, because some agreements are difficult to transfer without third-party consent.
• Employment, customer promises, and goodwill need to be managed carefully during the transition so you don’t lose value immediately after settlement.
• Getting the sale documents right (and not relying on generic templates) is one of the most effective ways to protect yourself from day one.
