Selling Shares in a New Zealand Private Company: Legal Checklist

Selling shares in your private company can be a smart move - whether you’re bringing in an investor, exiting the business (fully or partially), or restructuring ownership between founders.

But selling shares in a private company isn’t just a handshake and a bank transfer. In New Zealand, share transfers sit at the intersection of your company’s constitution, shareholder arrangements, director duties, and (sometimes) employee, tax and financial markets considerations.

If you get the legal steps right from the start, you’ll avoid delays, disputes, and “surprise” restrictions that can derail a deal late in the process.

What Does A “Sale Of Shares In A Private Company” Actually Mean?

When you sell shares, you’re selling ownership in the company (not the company’s assets). The buyer steps into your shoes as a shareholder, and the company continues operating as the same legal entity - with the same contracts, liabilities, employees, and obligations.

This is different from an asset sale, where the buyer purchases specific business assets (like equipment, stock, IP, or customer lists) and may leave certain liabilities behind.

Why The Distinction Matters

In a share sale, the buyer is effectively buying into the company “as is” - meaning they’ll care a lot about what the company has done in the past, and what risks may come with it. That’s why share sale transactions usually involve deeper due diligence and stronger protections (like warranties, indemnities, and conditions precedent).

Common Reasons NZ Businesses Sell Shares

• Founder exit or succession planning (full or partial sell-down)
• Raising capital by selling shares to an investor
• Adding a strategic partner (someone who brings customers, distribution, or industry expertise)
• Restructuring ownership (e.g. one shareholder buying out another)
• Creating an employee ownership pathway (usually via a structured scheme rather than a simple transfer)

Whatever your reason, it’s worth treating the process like a proper commercial transaction - because that’s what it is.

Before You Agree To Anything: Check The Rules That Control Share Transfers

One of the most common issues we see is business owners agreeing to sell shares, only to discover later that they can’t transfer them freely.

Before you negotiate price and terms, you should check what documents and legal rules govern your company’s shares, including:

• your Company Constitution (if you have one)
• any Shareholders Agreement
• your share register and current share structure
• any special share rights attached to particular share classes

Pre-Emptive Rights (Right Of First Refusal)

Private companies often include “pre-emptive rights” (also called a right of first refusal). This usually means a selling shareholder must offer the shares to existing shareholders first, before selling to an outsider.

This can be a great protective mechanism - but it can also slow down a deal if you don’t plan for the process and timeframes.

Director Discretion And Transfer Restrictions

Some constitutions allow directors to refuse to register a share transfer in certain circumstances. If that applies to your company, your transaction steps need to include the right approvals at the right time.

In practice, this means you should avoid promising a buyer “the deal is done” until you’ve confirmed the company can actually process and register the transfer.

If There’s No Constitution Or Shareholders Agreement

Even if your company doesn’t have bespoke documents in place, share transfers still need to be executed properly and recorded correctly under the Companies Act 1993. And if you’re bringing in a new investor, it’s usually a good time to put proper governance and decision-making rules in place (so everyone knows where they stand).

Key Legal Steps In A Share Sale (A Practical Checklist)

A clean sale of shares in a private company usually follows a clear sequence. The exact steps can vary depending on your deal, but here’s the typical roadmap.

1) Agree Heads Of Terms (So You’re Negotiating The Same Deal)

Many share sales start with a short document that outlines the commercial terms - like price, payment timing, due diligence, and key conditions. Depending on how it’s drafted, it may be binding, non-binding, or a mix of both.

The key is making sure you’re not accidentally committing to something you didn’t intend (for example, locking yourself into exclusivity or a “must sell” obligation before you’ve checked the transfer restrictions).

2) Due Diligence (What The Buyer Will Want To Check)

In a share sale, a buyer will usually conduct due diligence on the company. This can feel invasive, but it’s normal - and it’s often what separates a smooth transaction from a deal that collapses late.

Common due diligence areas include:

• company structure, share register, and governance
• financials, tax filings, and liabilities
• key customer and supplier contracts
• leases and property arrangements
• intellectual property ownership (e.g. whether the company actually owns its brand and key assets)
• employment arrangements and contractor arrangements
• privacy and data handling (especially if you collect customer information)

If your business collects personal information (like customer emails, delivery addresses, health information, or payment details), make sure your Privacy Policy is up to date and actually reflects what you do in practice.

3) Draft And Negotiate The Share Sale Agreement

The core legal document for a share sale is the share sale agreement. This sets out what’s being sold, for how much, and on what conditions.

A well-drafted agreement typically covers:

• the shares being transferred (and any share classes)
• purchase price and payment mechanics (including instalments or deferred payments if relevant)
• conditions precedent (things that must happen before completion)
• warranties (promises about the company’s position)
• indemnities (risk allocation for specific issues)
• restraints (if the seller is leaving and you need protections like non-compete or non-solicit)
• completion steps (what documents get signed and what gets updated)

This is the part you really don’t want to DIY. A generic template often won’t match your company’s governance documents, your deal structure, or the risk profile of your business.

4) Get The Right Company Approvals

Depending on your constitution and shareholder arrangements, you may need:

• director approval to register the transfer
• shareholder approval for related matters (especially if the deal changes control)
• waivers or consents if pre-emptive rights apply

If approvals are required and you skip them, you can end up with a buyer who paid for shares but can’t be properly registered - which is the kind of dispute no one wants.

5) Completion: Transfer Forms, Share Register, And Records

At completion, you’ll usually deal with practical (but crucial) steps like:

• executing share transfer documentation
• updating the company’s share register
• issuing or updating share certificates (if your company uses them)
• recording board resolutions and shareholder resolutions as required

These steps matter because, in a private company, the share register is a key record of ownership. If it isn’t updated correctly, it can create headaches later - especially if there’s a dividend, a future sale, or a dispute about voting rights.

Warranties, Indemnities, And Risk: What Sellers And Buyers Need To Think About

If you haven’t been through a share sale before, warranties and indemnities can feel like “extra legal stuff”. In reality, they’re the commercial engine room of many share deals.

What Are Warranties?

Warranties are statements of fact (or promises) about the company and the shares. If a warranty turns out to be untrue, the buyer may have a claim against the seller (depending on the agreement terms).

Warranties often cover areas like:

• the seller owns the shares free of encumbrances
• the company’s accounts are accurate
• there are no undisclosed liabilities
• contracts are valid and not in breach
• the company has complied with laws (including employment, privacy, health and safety)

What Are Indemnities?

An indemnity is usually a specific promise to cover a known risk if it eventuates. For example, if due diligence identifies a potential tax issue, the buyer may ask for an indemnity relating to that issue.

How To Manage Warranty Risk As A Seller

If you’re the seller, managing your warranty risk often involves:

• disclosing issues clearly (so they’re carved out of warranties)
• negotiating caps and time limits on claims
• being realistic about what you can promise (especially if you’re a minority shareholder without operational control)

This is also where having good internal paperwork helps. For example, if your team is employed under proper written Employment Contract terms and your key supplier arrangements are documented, it’s easier to support the warranties you’re being asked to give.

Don’t Forget The “Flow-On” Business Impacts (Employees, Contracts, Leases, And Privacy)

A share sale doesn’t usually require you to re-sign every contract (because the company is the same entity). But in the real world, ownership changes can still trigger practical and legal issues you’ll want to check early.

Key Contracts And “Change Of Control” Clauses

Some commercial agreements include clauses that allow the other party to terminate (or require consent) if there’s a change in ownership or control of the company.

This can apply to:

• major customer agreements
• supplier or distribution arrangements
• financing arrangements
• licences to use IP or software

If you suspect any contract might have change-of-control implications, make it part of your early deal planning - it’s much easier to obtain consents upfront than to scramble at completion.

Commercial Leases

Many businesses operate from leased premises, and lease terms can sometimes be sensitive to ownership changes (even if the tenant company doesn’t change).

If your transaction could trigger a consent requirement (or you’re not sure), it’s worth getting advice early and, where needed, having a Commercial Lease Review done as part of your transaction readiness.

Employees And Workplace Continuity

In most share sales, employees remain employed by the same entity (the company), so employment technically continues uninterrupted.

That said, a new owner may want to review employment arrangements, incentive plans, or leadership structures after the transaction. If you’re selling to an external buyer, think about how you’ll manage communications and continuity - particularly for key staff.

Privacy And Customer Data

Even though the company remains the same legal entity, a share sale can still raise privacy questions in practice (for example, if a new owner is getting access to customer databases or changing how data is used).

Under the Privacy Act 2020, businesses need to handle personal information in a way that’s lawful, transparent, and secure. If your transaction involves sharing data during due diligence, you may need confidentiality controls and careful scoping of what’s provided.

Key Takeaways

• A sale of shares in a private company transfers ownership of the company itself (including its history, liabilities, contracts, and obligations), so the legal process needs to be handled carefully.
• Before negotiating price or promising a buyer anything, check your Company Constitution and Shareholders Agreement for transfer restrictions, pre-emptive rights, and approval requirements.
• A typical share sale includes heads of terms, due diligence, a negotiated share sale agreement (with warranties and indemnities), required company approvals, and proper completion steps like updating the share register.
• Warranties and indemnities are how sellers and buyers allocate risk - and poorly drafted terms can lead to expensive disputes down the track.
• Even though the company stays the same entity, a share sale can still affect key contracts, financing, leases, and the practical handling of customer data under the Privacy Act 2020.
• Because tax outcomes and fundraising rules can vary a lot depending on your structure and who the buyer/investor is, it’s worth getting legal and accounting advice early (including where Financial Markets Conduct Act requirements may be relevant).
• Having your key documents in shape - like your Privacy Policy, your Employment Contract templates, and a clear governance setup - makes the transaction smoother and increases buyer confidence.
