Shareholder vs Director in New Zealand: Key Differences and Duties

If you’re running (or setting up) a company in New Zealand, it’s normal to feel a bit stuck on the difference between a shareholder and a director.

They’re both “part of the company”, and in small businesses the same people often wear both hats - but the legal roles are different. If you mix them up, you can end up with messy decision-making, disputes between founders, or (in the worst cases) personal liability for decisions you thought the company would cover.

Below, we’ll break down what shareholders and directors actually do, how the roles interact, and the legal responsibilities you need to understand so you can set your company up properly from day one.

Why The Difference Between Shareholder And Director Matters For Small Businesses

Here’s a simple way to think about it:

• Shareholders typically own the company (or a portion of it).
• Directors generally govern the company (they make board-level decisions and oversee management).

Understanding the difference between shareholder and director matters because it affects:

• Who has authority to make decisions day-to-day (or sign contracts) for the company
• Who can be held responsible if something goes wrong
• How you raise investment (ownership vs control)
• What happens if someone wants out (selling shares vs resigning as a director)
• How you prevent disputes between co-founders and investors

A common small business scenario is this: you and a friend start a company 50/50, you both assume you can make decisions, and you never properly document who does what. Then you hit a growth moment - hiring staff, signing a lease, bringing in an investor - and suddenly you realise you need clarity around ownership, control, voting, and responsibilities.

That’s why it’s usually worth putting proper foundations in place early, including a Shareholders Agreement (especially if you have more than one owner).

What Does A Shareholder Do (And What Rights Do They Have)?

A shareholder is a person (or entity, like another company or a trust) that owns shares in a company.

In practice, shareholders usually:

• contribute capital (money or assets) to help the company start or grow
• take on the “upside” if the business grows (the value of their shares increases)
• receive dividends if the company decides to pay them (not automatic)
• vote on major company decisions where shareholder approval is required

Shareholders Own The Company (But Don’t Automatically Run It)

This is one of the biggest points people miss when they’re trying to understand the difference between shareholder and director.

Being a shareholder does not automatically mean you:

• can sign contracts on the company’s behalf
• can instruct staff or contractors
• can access the company bank account
• can make operational decisions

Those powers usually sit with the directors (and then management), unless the Companies Act, the company’s constitution, or shareholder arrangements require shareholder approval for a particular matter.

Common Shareholder Rights In NZ Companies

Shareholders’ rights come from a mix of sources, including the Companies Act 1993, the company’s constitution (if it has one), and any shareholder arrangements.

Depending on the company and what’s been agreed, shareholder rights often include:

• Voting rights on major matters (for example appointing directors, adopting or changing a constitution, approving major transactions in some cases, or other decisions reserved to shareholders)
• Rights to receive information that the Act requires the company to provide (for example, access to certain company records and shareholder information, and financial statements where applicable)
• Rights relating to share transfers (for example, restrictions on selling shares to outsiders)

In a small business, these rights are often clarified and expanded in a Company Constitution and a Shareholders Agreement.

Shareholders Usually Have Limited Liability (But Not Always)

One reason people choose to operate through a company is limited liability - meaning shareholders are generally not personally responsible for the company’s debts just because they own shares.

But “limited liability” doesn’t mean “no risk”. Shareholders can still face personal exposure if, for example:

• they’ve given a personal guarantee (common with bank lending or commercial leases)
• they’ve acted in a way that creates personal liability (depending on the situation)
• they’re also a director (director duties and liability are separate - we’ll cover that below)

What Does A Director Do (And What Duties Do They Owe)?

A director is responsible for governing the company. Directors make decisions they believe are in the best interests of the company, and they have legal duties they must follow.

In small businesses, directors often also act as the “hands-on” operators - but legally, the director role is about governance and oversight (even if day-to-day management is delegated).

Directors Manage The Company’s Governance And Decision-Making

Directors typically have the power to:

• enter into contracts on behalf of the company (subject to any limits in the constitution or matters reserved to shareholders)
• open bank accounts and approve spending
• hire and manage staff (or delegate management)
• set strategy, budgets and risk settings
• ensure the company complies with legal and regulatory obligations

If you’re negotiating roles with a co-founder, it helps to document who has what authority (and what happens if you disagree). This is often set out in a Founders Agreement early on, then reflected in your company governance documents as the business matures.

Director Duties In New Zealand (Companies Act 1993)

Directors’ duties are a key part of the difference between shareholder and director - because shareholders generally don’t owe these governance duties just by owning shares.

Under the Companies Act 1993, directors have duties that include (in plain English):

• Acting in good faith and in the best interests of the company
• Using powers for a proper purpose (not for personal advantage, or to benefit one shareholder unfairly)
• Complying with the Act and the company’s constitution
• Not trading recklessly (for example, carrying on business in a way likely to create a substantial risk of serious loss to creditors)
• Not incurring obligations the company can’t perform (for example, signing contracts when the company can’t pay or deliver)
• Exercising care, diligence, and skill

These duties apply even if you’re a “silent” director or you’re not involved day-to-day. If you’re listed as a director, you’re expected to take the role seriously.

It’s also worth understanding potential personal exposure, because directors can face liability in certain circumstances. This is why many business owners look closely at personal liability as a company director before taking on (or continuing) the role.

Directors Must Manage Conflicts Of Interest

Conflicts are common in small businesses, especially where:

• directors are also shareholders
• the business does deals with related parties (family members, trusts, other companies you own)
• different founders have different risk appetites

Good governance means identifying conflicts early, documenting them, and handling approvals properly. If you don’t, disputes can escalate quickly - and sometimes a director’s decision can be challenged if it wasn’t made appropriately.

Can The Same Person Be Both A Shareholder And A Director?

Yes - and in NZ small businesses, it’s extremely common for the same person to be both a shareholder and a director.

But even if you wear both hats, you still need to understand which “hat” you’re wearing when you make decisions.

A Practical Example

Imagine you co-own a company 50/50 with another founder, and you’re both directors.

• As shareholders, you and your co-founder might vote on major changes (like issuing new shares to an investor or changing the constitution).
• As directors, you might approve signing a supplier agreement, hiring staff, or taking on debt.

This distinction becomes even more important when the company grows and you add:

• an investor shareholder who is not involved in operations
• an independent director who is not an owner
• employees who need clarity on who can direct work and approve spending

What If A Shareholder Disagrees With The Directors?

This is where clear documents and clear processes matter.

Shareholders can’t usually step in and run the company just because they don’t like a decision. However, shareholders may have certain rights to:

• vote to appoint or remove directors (depending on the Act, the constitution, and any agreed thresholds)
• bring matters to a shareholder meeting
• exercise rights set out in a Shareholders Agreement or constitution

If you want rules around decision-making, voting thresholds, reserved matters (decisions requiring shareholder approval), and exit pathways, a properly drafted Shareholders Agreement is often the cleanest way to reduce future disputes.

What Happens When Ownership Or Control Changes?

In real life, companies don’t stay static. People join, people leave, investors come in, founders step back, and roles evolve.

This is where understanding the difference between shareholder and director helps you manage change cleanly.

Changing Shareholders (Ownership)

A change in shareholders usually happens when:

• someone sells their shares
• new shares are issued to raise capital
• shares are transferred (for example, to a family trust or holding company)

Any share movement needs to be handled properly - not just with an informal email agreement. The company should keep accurate records, and you may need formal documents depending on the transaction.

If you’re moving ownership around (for example, one founder buying the other out, or bringing in an investor), it’s worth getting advice on transferring shares and how that impacts control, voting rights, and future exits.

Changing Directors (Control)

A director can be appointed or resign, and the company should follow proper processes and update the Companies Office records where required.

Directors should also make sure key decisions are properly documented - for example, major approvals or governance steps are often recorded through formal company resolutions. If you need a straightforward starting point for documentation, a Directors Resolution can be part of keeping your company records clean and consistent.

When Both Change At Once

Many “business partner breakup” scenarios involve both a change in shareholding and

In those situations, you’re not just managing ownership. You’re also managing:

• who has authority to make decisions going forward
• who is responsible for past decisions
• ongoing obligations (like personal guarantees, leases, or loans)
• access to company systems, bank accounts, and IP

It’s also common for people to loosely describe this as “changing the company ownership”, but it’s important to separate the ownership piece from governance and control. If you’re heading into a restructure or buyout, it helps to understand the legal steps involved in changing company ownership so nothing is missed.

How To Set Up Clear Roles And Protect Your Business From Day One

If you’re starting (or cleaning up) your company structure, the goal is to make ownership and control clear, and to reduce risk when the business hits stressful moments (cashflow crunches, growth opportunities, disagreements, exits).

1. Decide Who Owns What (And What That Actually Means)

Talk through:

• who holds shares and in what percentages
• whether shares are issued upfront or earned over time (vesting can be useful for early-stage businesses)
• what happens if someone stops working in the business

Many disputes happen because someone thinks shares are “just a reward for effort”, while another person sees them as “permanent ownership”. You want to align expectations early.

2. Decide Who Controls What (And Document Authority)

Ask:

• Who are the directors?
• What decisions can one director make alone?
• What decisions require unanimous director approval?
• What decisions require shareholder approval?

This is one of the most practical ways to manage the difference between shareholder and director in day-to-day operations.

3. Put Your Governance Documents In Place

In many small businesses, the documents that create clarity are:

• a Shareholders Agreement (to manage ownership, exits, and decision-making rules)
• a Company Constitution (to set internal governance rules and how the company operates)

These documents should work together. For example, your Shareholders Agreement might say certain big decisions require shareholder approval, while the constitution sets out how shareholder meetings and voting work.

4. Don’t DIY The “Important Bits”

Templates can be tempting - especially when you’re trying to move fast and keep costs down - but company ownership and director duties aren’t the place to guess.

If the documents don’t match your real arrangements, you can end up with:

• unclear authority (who can sign what)
• deadlocks between owners
• unexpected dilution when raising capital
• exit disputes (including pricing fights and restraint issues)
• governance steps that weren’t validly done

Getting advice early is usually much cheaper than trying to untangle a dispute later.

Key Takeaways

• The core difference between a shareholder and a director is that shareholders generally own the company, while directors govern the company and make key decisions.
• Shareholders typically have rights around voting on major matters, receiving dividends (if declared), and benefiting from business growth - but they don’t automatically have authority to manage operations.
• Directors have serious legal duties under the Companies Act 1993, including acting in the best interests of the company, avoiding reckless trading, and exercising care and diligence.
• In small businesses, the same people are often both shareholders and directors, but it’s still important to separate “ownership decisions” from “director decisions”.
• When shares are sold, issued, or transferred, ownership changes - and this should be documented properly to avoid disputes and governance issues later.
• Clear documents like a Company Constitution and Shareholders Agreement can prevent deadlocks and protect your business as it grows.
