Buying or Selling a Business in New Zealand: Common Legal Mistakes

A business sale can look straightforward on paper, but the legal risks often show up in the details. Sellers commonly overpromise what the business includes, buyers often rely on assumptions instead of proper due diligence, and both sides regularly leave key points too vague in the sale agreement. That is where deals start to wobble, or worse, where expensive disputes begin after settlement.

In New Zealand, buying or selling a business usually involves much more than agreeing on a price. You may need to deal with leases, staff, supplier contracts, intellectual property, privacy obligations, restraint clauses, and the difference between an asset sale and a share sale. Each of those choices changes the legal risk.

This guide explains the most common mistakes in a business sale, when they usually come up, and what practical steps can help you avoid problems before you sign a contract and before you spend money on setup or transition.

Overview

A business sale works best when the parties document exactly what is being bought, what risks are being accepted, and what must happen before settlement. Most problems come from unclear terms, weak due diligence, or missed third party consents.

• Confirm whether the deal is an asset sale or a share sale
• Define exactly what is included, such as stock, plant, customer lists, trade marks, websites and goodwill
• Check the lease position and whether landlord consent is needed
• Review employee arrangements and who is responsible for final pay, leave and new employment contracts or other new employment documentation
• Test supplier, customer and finance contracts for assignment limits or change of control clauses
• Verify financial records, key licences, registrations and ownership of intellectual property
• Make sure warranties, indemnities, restraints and settlement conditions are clearly drafted
• Plan handover obligations, training, announcements and post settlement access to records

What Business Sale Means For New Zealand Businesses

A business sale is the transfer of a trading operation from one owner to another, but the legal effect depends on the structure of the deal. The first thing to get clear is whether the buyer is purchasing business assets or buying shares in the company that owns the business.

Asset sale or share sale

In an asset sale, the buyer usually picks up selected business assets and rights. That can include equipment, stock, branding, a phone number, a website, customer contracts, and goodwill. The seller usually keeps the existing company unless the deal says otherwise.

In a share sale, the buyer acquires shares in the company itself. That means the company generally keeps its contracts, liabilities, records and legal history, unless changes are separately negotiated. Buyers often like continuity, but the risk is that hidden liabilities may come with the company.

This distinction matters because it affects due diligence, contract drafting, consents, employee arrangements and risk allocation. Founders often get caught when they negotiate the headline price before they understand which structure actually suits the deal.

What is usually being sold

Many owners say they are selling “the business”, but that phrase is too loose for a legal agreement. The contract should spell out the exact assets, rights and obligations involved.

Common sale items include:

• business name and goodwill
• stock and inventory
• plant, equipment and vehicles
• website, domain names and social media accounts
• trade marks, logos and other branding
• customer lists and databases
• supplier and customer contracts
• phone numbers, email accounts and software subscriptions
• leases or rights to occupy premises

Some of these items can only transfer if the legal ownership is clear. For example, a logo may have been designed by a freelancer years ago, but if the rights were never properly assigned to the business, the seller may not actually own it in a way that can be sold cleanly.

New Zealand legal context

New Zealand business sales often touch several legal areas at once. Depending on the business, you may need to consider Companies Office records, personal property security interests, employment obligations, privacy compliance, fair trading issues, and whether any industry specific licences or permits are tied to the current owner.

That does not mean every deal is complicated, but it does mean casual paperwork can create real risk. A short heads of agreement or email trail is rarely enough to protect either side in a meaningful transaction.

When This Issue Comes Up

Business sale issues usually arise well before settlement, often as soon as one party starts making assumptions. The legal work starts when the deal is being shaped, not only when someone asks for a final contract.

When an owner decides to exit

A seller often starts by speaking with a broker, accountant or potential buyer. At that point, confidential financial information may be shared, the price may be floated, and informal promises may be made about what the buyer will receive.

This is where sellers should slow down. Before you sign a contract or hand over sensitive records, you need clarity on confidentiality, deal structure, key assets and any problems that could affect value.

When a buyer spots an opportunity

Buyers often move quickly when a business seems undervalued or has strategic value. The risk is paying a deposit, signing a basic offer, or spending money on setup without checking whether the business can actually be transferred in the way expected.

For example, a buyer might assume the lease can continue, that all staff will stay, or that the website and trade mark are owned by the seller. Those assumptions can fall apart during due diligence.

When the business has employees, premises or regulated operations

The more moving parts a business has, the more likely legal issues will arise. A café with leased premises, a software business holding customer data, or a services business built around a founder's personal relationships can all present very different risks.

Common trigger points include:

• the premises are leased and landlord consent is required
• important supplier contracts cannot be assigned without consent
• the company has employees with accrued entitlements or incomplete records
• the business handles personal information and customer communications need to be managed carefully under its privacy obligations
• the value of the business depends heavily on branding, know how or goodwill
• the seller is expected to stay on for a handover period

When the parties rely on a template

A template can help with structure, but it will not fix the wrong assumptions. This is a common mistake in smaller New Zealand deals where the parties know each other and want to keep things simple. The problem is that each business has its own assets, consents, risks and handover issues.

A generic form may leave major gaps around stock adjustments, employee transfer, restrictive covenants, deferred payments, vendor finance or claims after settlement. Those gaps usually become visible only when something goes wrong.

Practical Steps And Common Mistakes

The safest approach is to identify the legal pressure points early and document them clearly in the sale process. Most business sale disputes can be traced back to one of a handful of avoidable mistakes.

1. Treating the price as the whole deal

The purchase price matters, but it is only one part of the transaction. A deal with a good price and poor legal terms can still be a bad deal.

Both sides should pin down:

• what exactly is being sold
• how the price is calculated
• whether stock is included or valued separately
• whether part of the price is deferred or conditional
• what happens if key conditions are not met before settlement

A common example is where the parties agree on a headline figure, but later discover the seller intended to exclude some equipment, software accounts or debtors. Another example is where stock is counted differently by each side, causing an argument just before completion.

2. Choosing the wrong deal structure

Asset sales and share sales create different risks. Buyers sometimes prefer an asset purchase to avoid historical liabilities. Sellers sometimes prefer a share sale for simplicity or commercial reasons. Neither option is automatically better.

The main mistake is choosing a structure without testing the practical consequences. In a share sale, the buyer may inherit unresolved liabilities, weak contracts or past compliance issues. In an asset sale, the buyer may need to re-paper contracts, obtain fresh consents and put new employment arrangements in place.

The right structure should be decided with the legal and accounting consequences in mind. Tax treatment is important here, so a business should also speak with its accountant or tax adviser.

3. Skipping or rushing due diligence

Buyers should assume nothing until the records support it. Due diligence is not about mistrust, it is about checking that the business being sold matches the story being told.

A practical due diligence review often covers:

• financial statements and management accounts
• major customer and supplier contracts
• leases and property arrangements
• employee records and key contractor terms
• intellectual property ownership
• privacy practices and customer data handling
• finance documents and security interests
• complaints, disputes and outstanding claims
• licences, permits and registrations

One common mistake is focusing only on revenue and profit while ignoring contract quality. A business may look healthy financially, but if its largest customer has no written agreement, or can terminate on short notice, the value may be far less secure than expected.

4. Failing to confirm ownership of key assets

Sellers often assume the business owns its branding, content and systems, but ownership can be messy. If a founder built the website personally, if a contractor created core materials, or if software licences are in someone else's name, the sale can hit avoidable delays.

Buyers should verify ownership and transferability of:

• trade marks and brand assets
• domain names and hosting accounts
• website content and marketing materials
• custom software or code
• databases and customer relationship tools
• phone numbers, email systems and social media accounts

This is especially important where the business trades online or depends heavily on digital channels. A brand can carry much of the purchase price, but only if the legal rights are actually in place.

5. Missing lease and consent issues

Premises can make or break a deal. If the business operates from a leased site, you need to know early whether the lease can be assigned, whether landlord consent is required, and whether any arrears or breaches exist.

Buyers sometimes spend money on fit out planning or transition costs before the lease position is secure. Sellers sometimes promise continuity without checking the lease terms. The same issue can arise with franchise agreements, distribution arrangements, equipment finance and software subscriptions.

Before you sign, identify any contract that may need consent or replacement. Settlement should usually be conditional on critical consents being obtained.

6. Handling employees casually

Staff issues are often sensitive and highly practical. In an asset sale, employees do not automatically move across on the same basis just because the business changes hands. In a share sale, the employing company usually stays the same, but there may still be employment risks in the company that the buyer is acquiring.

The parties should clarify:

• which employees are expected to stay
• who is responsible for accrued leave and final entitlements
• whether new employment agreements are needed
• when staff will be told about the sale
• whether any key employees need retention arrangements

A common mistake is leaving staff communication too late or failing to review employment records before settlement. Poor records can create uncertainty around pay, leave and other obligations, which can quickly become a buyer concern.

7. Using weak warranties and indemnities

Warranties are statements the seller makes about the business, and indemnities allocate risk for specific issues. These clauses matter because they give buyers recourse if the business is not what was promised, and they give sellers a framework to limit and define that exposure.

Weak drafting often creates two opposite problems. Buyers may get broad promises that are hard to enforce in practice, or sellers may accept open ended liability without sensible limits. The contract should deal clearly with what is warranted, what has been disclosed, how long claims can be made, and whether there are caps or thresholds.

This is one of the most negotiated parts of a business sale because it goes directly to who carries the risk after settlement.

8. Forgetting restraint and goodwill protections

If a buyer is paying for goodwill, the buyer will usually want the seller restrained from competing, soliciting customers or poaching staff for a period after settlement. Sellers often accept a restraint clause without appreciating how broad it is.

The main legal question is whether the restraint is reasonable in scope, time and geographic area. A restraint that is too wide may be harder to enforce. A restraint that is too narrow may not protect the buyer's bargain.

The right wording depends heavily on the business. A local service business may justify a different restraint from a digital business serving customers nationwide.

9. Mishandling confidential information and privacy

Most sales involve sharing commercially sensitive records. That should happen on a controlled basis, particularly if the buyer is a competitor or may not complete the deal.

Confidentiality terms should cover what information can be used, who can see it, and what must happen if negotiations end. Privacy obligations also matter if customer or employee personal information is being reviewed or transferred. The parties should think carefully about what can be disclosed at due diligence stage, what should be de-identified, and what notices or contractual protections may be needed.

This is where founders often get caught in online businesses, professional services, healthcare-adjacent operations, and any business with a valuable customer database.

10. Leaving the handover too vague

Settlement is not the end of the transaction. Many businesses need active handover support from the seller, especially where customer relationships, operational know how or bespoke systems are involved.

The agreement should spell out:

• how long the handover lasts
• whether training is included
• who introduces the buyer to key customers and suppliers
• what records and access credentials must be provided
• whether the seller will stay on as a consultant or employee for a short period under a service agreement

Without that detail, expectations can diverge quickly. Buyers may expect significant assistance, while sellers may think their involvement ends at settlement.

11. Signing too early

Momentum can be useful, but rushing into a binding commitment is risky. Heads of agreement, letters of intent and term sheets can carry legal consequences even when the parties think they are only setting out broad principles.

Before you sign a contract, check whether it is intended to be binding, what exclusivity or confidentiality obligations it creates, and whether key conditions have been clearly stated. A short preliminary document can shape the whole deal, for better or worse.

FAQs

Is a business sale the same as selling a company?

No. A business sale may be an asset sale, where selected assets and rights are transferred, or a share sale, where the company itself is sold. The legal and commercial consequences can be quite different.

Do I need landlord consent to sell my business?

Sometimes, yes. If the business operates from leased premises and the lease is being assigned, landlord consent is often required. The lease terms need to be checked early in the transaction.

Do employees automatically transfer to the buyer?

Not always. In an asset sale, new employment arrangements may be needed. In a share sale, the employing entity usually stays the same, but the buyer should still review employment records and risks carefully.

What should buyers look for in due diligence?

Buyers should review financial records, contracts, leases, employee arrangements, intellectual property, privacy practices, licences, disputes and any security interests. The aim is to confirm value and identify risks before settlement.

Can I use a simple template for a business sale?

A template may help as a starting point, but many deals need tailored drafting. If the sale involves staff, a lease, deferred payments, special warranties, restraints or intellectual property, a generic document may leave major gaps.
