Contract Sales for Shares and Businesses in New Zealand: Legal Steps and Risks

If you are buying or selling a business in New Zealand, the contract sale document is where deals often go right, or go badly wrong. Founders and small business owners regularly make the same mistakes: relying on a heads of agreement as if it settles everything, assuming the price is the only commercial issue that matters, or signing standard sale terms before due diligence is finished. Another common problem is missing the difference between a share sale and an asset sale, then discovering too late that the liabilities, employees, leases, or customer contracts do not transfer the way you expected.

This guide explains what contract sales means in the context of share and business transactions in New Zealand, what legal issues you need to check before you sign, and where business owners most often get caught. If you are negotiating a sale, buying into an existing company, or exiting your business, this is the groundwork to get right before you rely on a verbal promise or spend money on the transaction.

Overview

A contract for sale in a business transaction sets out exactly what is being bought, what is excluded, when completion happens, and who carries which risks before and after settlement. In New Zealand, the right structure and the right drafting matter because a share sale and a business asset sale produce very different legal and commercial outcomes.

• Confirm whether the deal is a share sale, an asset sale, or a mixed transaction.
• Identify precisely what is included in the sale, such as equipment, stock, IP, goodwill, contracts, customer data and employees.
• Check conditions precedent, including finance, landlord consent, third party consents, due diligence and regulatory approvals if relevant.
• Review warranties, indemnities and restraint clauses closely, because this is where future risk is often allocated.
• Make sure the purchase price mechanics, stock adjustment, settlement steps and handover obligations are clear.
• Consider privacy, employment, fair trading and other operational issues that continue after completion.

What Contract Sales Means For New Zealand Businesses

For New Zealand businesses, contract sales usually refers to the written sale agreement used when ownership of a business, company shares, or business assets changes hands. The document is not just paperwork, it is the legal framework that decides what the buyer gets and what the seller remains responsible for after settlement.

People often use the term loosely, but there are two common transaction structures. Each has a different risk profile.

Share sale

In a share sale, the buyer purchases shares in the company that operates the business. The company itself continues to own its assets and remains party to its existing contracts, leases and obligations.

That can be simpler operationally, but the buyer is effectively stepping into ownership of a company with its history intact. If the company has old liabilities, unresolved disputes, weak compliance practices or poor records, those issues may still exist after completion.

For sellers, a share sale can be cleaner from an asset transfer perspective because the business stays inside the same legal entity. For buyers, the main risk is inheriting more than they expected.

Business asset sale

In an asset sale, the buyer purchases selected business assets rather than the shares in the company. This might include plant, stock, equipment, goodwill, intellectual property, domain names, customer lists, and the benefit of some contracts if they can be assigned.

This structure gives the buyer more control over what they take on. It also means more work, because each asset category may need separate transfer steps. Leases may need landlord consent. Customer or supplier contracts may need novation or assignment. Employee arrangements need careful handling.

For sellers, an asset sale can leave the original company behind with any assets or liabilities that are not transferred. That can be useful, but only if the contract clearly says what remains.

Why the distinction matters

The legal and practical consequences change depending on deal structure. Before you sign a contract sale, you need clarity on issues such as:

• whether employees transfer and on what terms
• whether the lease stays in place or needs a new agreement
• whether licences, permits or regulatory registrations can be transferred
• whether customer data can be shared under the Privacy Act 2020
• whether the buyer takes on historical liabilities, tax risks or warranty claims
• whether trade marks, software licences and other intellectual property are actually owned by the seller and can be transferred

Many SME deals start with broad commercial agreement on price, timing and handover. That is only the beginning. The sale contract turns those high level discussions into enforceable obligations, and this is where founders often get caught if important details were left to later.

What a business sale agreement usually covers

A properly prepared contract sale for a New Zealand business transaction often includes terms dealing with:

• the buyer and seller details
• the exact assets, shares or business being sold
• the purchase price and how it is paid
• deposits, adjustments and apportionments
• conditions that must be satisfied before settlement
• warranties about the business and its financial position
• indemnities for specific identified risks
• confidentiality obligations
• restraint of trade or non-solicitation clauses
• employee transfer or termination arrangements
• intellectual property ownership and assignment
• handover, training or transition support after completion
• dispute resolution and termination rights

Some transactions also have related documents, such as a shareholders agreement, deed of assignment, IP assignment, restraint deed, lease consent, consultancy agreement for the outgoing owner, or board and shareholder resolutions.

Legal Issues To Check Before You Sign

Before you sign a contract sale, you need to know exactly what is being transferred, what assumptions the document makes, and which risks sit with each party after completion. A well-negotiated agreement should reflect the real business you are buying or selling, not an idealised version of it.

Deal structure and parties

Start by confirming the legal structure of the transaction. If the buyer thinks they are only buying a trading operation, but the contract is actually for shares in a company with old liabilities, the gap can be expensive.

Check that the correct parties are signing. In founder-led businesses, assets are sometimes held in different places. A trade mark might be owned personally. Software may have been developed by a contractor without a signed IP assignment. A vehicle might be leased, not owned. The contract should match the legal reality.

Due diligence and disclosure

Due diligence gives the buyer a chance to test the seller's statements before completion. It also gives the seller a chance to disclose known issues in a structured way so there is less room for dispute later.

Areas commonly reviewed include:

• company records and Companies Office filings
• material customer and supplier contracts
• leases and property occupation rights
• employment agreements, contractor arrangements and disputes
• ownership of IP, software and branding
• financial records and outstanding debts
• privacy compliance and data handling practices
• insurance arrangements
• any claims, complaints or regulator contact

Sellers should be careful not to make broad assurances that are not backed by records. Buyers should be careful not to skip due diligence because the seller is known to them or because the business appears straightforward.

Warranties and indemnities

Warranties are promises about the state of the business. Indemnities are liability clauses that require one party to cover certain losses if a specified issue arises. These provisions often matter more than general legal boilerplate.

A buyer may ask for warranties that the accounts are accurate, there is no undisclosed litigation, tax obligations have been met, IP ownership is valid, and all material contracts are in force. A seller will usually try to limit those promises by time, knowledge, disclosure and financial caps.

Indemnities are often used where a specific issue has already been identified, such as a past employment issue, unresolved supplier dispute, or uncertain ownership claim. Sellers should resist open-ended indemnities. Buyers should make sure any known risk is addressed specifically, rather than hoping broad warranty wording will cover it.

Conditions precedent

Many business sale contracts are signed before every issue is finalised. Conditions precedent are the mechanism that allows the parties to commit to the deal while requiring certain matters to be completed first.

Common conditions include:

• satisfactory due diligence
• finance approval
• landlord consent to lease assignment or a new commercial lease
• third party consent for assignment of key contracts
• board or shareholder approval
• regulatory or licence-related approvals where relevant to the business

The drafting matters. The contract should set deadlines, explain who must take what steps, and state what happens if the condition is not satisfied or waived.

Employees and contractors

Employee arrangements are often underestimated in contract sales. In an asset sale, employees do not always move automatically with the business, and the parties need to decide who is responsible for accrued entitlements, notice obligations and any offers of new employment.

Contractors can be an issue too. If the business depends on key freelancers or consultants, the buyer should confirm whether those relationships can continue after settlement and whether the underlying contracts allow assignment.

If the business handles personal information about staff, customers or clients, any transfer of records needs to be managed carefully under the Privacy Act 2020 and any applicable privacy notice.

Lease, premises and assets in use

If the business operates from leased premises, the lease position can determine whether the transaction is viable. A buyer should not assume they can simply continue in occupation after settlement.

Check:

• whether the lease is current and compliant
• whether landlord consent is needed
• whether there are rent arrears or breaches
• whether any make good or reinstatement obligations exist
• whether fitout, equipment or signage is owned, leased or financed

Where plant or equipment is subject to finance or security interests, further steps may be needed before clear title can pass.

Restraints and goodwill protection

If a buyer is paying for goodwill, they will usually want the seller restricted from competing for a period after settlement. This may be framed as a restraint of trade, non-solicitation obligation, or a ban on approaching staff or customers.

These clauses need to be reasonable and carefully drafted to have a better chance of being enforceable. Overreaching wording can create uncertainty and weaken protection.

Consumer, marketing and privacy issues after completion

A business sale does not erase ongoing compliance obligations. If the buyer continues using existing advertising, website claims, customer representations or product descriptions, the Fair Trading Act 1986 may still be relevant. Misleading statements about the business, its results, or its products can create post-sale exposure.

If the business provides goods or services to consumers, the Consumer Guarantees Act 1993 may also affect how complaints and service issues are handled after settlement. The sale contract should deal with responsibility for pre-completion and post-completion claims where possible.

Price mechanics and settlement process

The purchase price is not just a number. It can change depending on stock valuation, work in progress, debtor realisation, retention amounts or earn-out terms.

Before you sign, make sure the contract states:

• how the price is calculated
• when payment is due
• whether there is a deposit
• how stock is counted and valued
• whether any amount is retained for claims
• what documents and deliverables must be handed over at settlement

If the outgoing owner is staying on for a transition period, that arrangement should be documented separately or clearly within the sale agreement, using clear written terms.

Common Mistakes With Contract Sales

The most common contract sales mistakes are not dramatic legal errors, they are practical gaps that create avoidable disputes later. Small omissions in the drafting can leave one side paying for assumptions that were never actually written down.

Treating the term sheet as the final deal

A heads of agreement or email summary can be useful, but it is rarely enough on its own. Parties often act as if the key deal is already settled, then become frustrated when the formal contract introduces real issues around liability, conditions, restraints or handover.

The fix is simple: treat early commercial documents as a starting point only, unless they are intentionally drafted to be binding on specific points.

Using the wrong sale structure

Buyers sometimes agree to a share purchase without fully appreciating they are acquiring the company with its history. Sellers sometimes assume an asset sale transfers everything neatly, when in reality customer contracts, leased equipment or software licences need separate consent or assignment.

This mistake usually shows up late, when completion is close and someone realises a key asset cannot move the way they expected.

Relying on verbal promises

If the seller says major customers are secure, key staff will stay, or a landlord is relaxed about the transfer, that should not stay as a conversation only. Put material promises into the contract, disclosure schedule, or condition precedent.

Before you rely on a verbal promise, ask whether it is important enough to be enforceable. If the answer is yes, it should be written down.

Missing ownership gaps

Founders often assume the business owns all its branding, content, software and know-how. Sometimes it does not. Trade marks may never have been registered. Code may have been built by a contractor. Product photos or marketing assets may have been licensed only for limited use.

In a sale, these gaps matter because the buyer may be paying for assets that the seller cannot legally transfer.

Overlooking privacy and customer data issues

Customer lists are valuable, but they are not just commercial assets. Personal information needs to be handled lawfully. The parties should think about what can be shared during due diligence, what should be anonymised, and what notices or internal steps may be required before records are transferred.

Ignoring employee obligations

It is common for owners to focus on customers and stock, then realise late in the process that employment arrangements are unclear. Who pays leave balances, what offers are made, and who deals with pre-completion issues should be addressed early.

Employment issues can become emotional quickly, especially in founder-led businesses where staff relationships are personal as well as contractual.

Accepting wide warranty exposure without limits

Sellers sometimes agree to broad warranties because they seem standard. The real question is how long those warranties last, what disclosure qualifies them, whether there is a claim threshold, and whether total liability is capped.

Without those limits, a seller may remain exposed long after they thought the deal was done.

Using generic templates for a non-generic deal

A simple template may not fit a business with leased premises, regulated activity, multiple shareholders, custom software, imported products, or a staged earn-out. Founders often download a contract that covers the sale at a high level but misses the points that matter in the actual business.

The result is usually one of two things: a false sense of security before signing, or expensive negotiation after the problems surface.

FAQs

Is a share sale better than an asset sale?

Neither is automatically better. A share sale may be simpler operationally, while an asset sale can give the buyer more control over which liabilities they take on. The right choice depends on the business, the risk profile, and the commercial deal.

Do I need due diligence if I know the seller personally?

Usually, yes. Personal trust does not replace legal and commercial verification. Due diligence helps confirm ownership, liabilities, contracts, lease position, employee issues and compliance practices before you sign.

Can customer contracts transfer automatically in a business sale?

Not always. Some contracts can be assigned, some need consent, and some need a new agreement entirely. You need to review the contract terms rather than assuming the buyer can step in automatically.

What happens to employees in a business sale?

That depends on the sale structure and the arrangements made between the parties. In many cases, the contract should clearly allocate responsibility for termination, new employment offers, accrued entitlements and any pre-completion issues.

Are restraint of trade clauses enforceable in New Zealand?

They can be, but only to the extent they are reasonable and drafted properly. A clause that goes further than necessary to protect legitimate business interests may be difficult to enforce.

Key Takeaways

• A contract sale for a New Zealand business transaction should clearly identify whether the deal is a share sale or an asset sale, because that changes what transfers and which risks remain.
• Price is only one part of the transaction. Warranties, indemnities, conditions precedent, restraints, handover obligations and settlement mechanics often matter just as much.
• Due diligence is essential before you sign, even where the parties know each other well or the business seems straightforward.
• Founders often get caught by lease issues, employee arrangements, privacy concerns, ownership gaps in IP and overreliance on verbal promises.
• The sale agreement should reflect the actual business records, assets, liabilities and third party consents required for completion.
