New Zealand Director Duties: What Every Company Director Must Know

Becoming a company director can feel like a natural next step when your business is growing. Maybe you’re registering a company for the first time, bringing on investors, or formalising a structure that started out as “just a side hustle”.

But here’s the thing: once you’re a director, you’re not just “helping run the business”. You’re taking on legal duties that can create real personal risk if they’re ignored.

Don’t stress - director duties in New Zealand are manageable when you understand what’s expected, keep good processes in place, and get the right documents sorted early.

What Does A Director Do (And Why Do Director Duties Matter)?

A director is responsible for governing and overseeing a company. In a small business, that often means the director is also the owner and the person doing the day-to-day work - but legally, the “director role” is still distinct.

Director duties matter because, in New Zealand, directors owe duties under the Companies Act 1993. These duties exist to protect the company (and indirectly shareholders, creditors, and the market), and they apply even if:

• you’re the only director and the only shareholder;
• your company is a small family business;
• you didn’t realise the decision was “a director decision”; or
• you were trying to do the right thing but didn’t follow a proper process.

In other words, being a director comes with legal responsibilities that you can’t ignore just because your business is small or informal.

If you’re setting your company up properly, a clear Company Constitution can help define how decisions are made, what powers directors have, and how shareholder approvals work - which makes it much easier to meet your director obligations in practice.

What Are The Core Director Duties Under The Companies Act 1993?

New Zealand director duties are mainly found in the Companies Act 1993. These duties set the baseline for how a director must act.

While the law has detail and exceptions, you can think of the core director duties as falling into a few practical categories.

1. Acting In Good Faith And In The Best Interests Of The Company

A director must act in good faith and in what they believe to be the best interests of the company.

For small business owners, this can be tricky because it’s easy to blur the lines between “the company’s interests” and “my interests”. They often align - but not always.

Examples where this duty can come up include:

• approving payments to yourself or family members;
• deciding whether to take on debt;
• selling business assets to a related party;
• making decisions that benefit one shareholder more than another.

If there’s more than one shareholder, a tailored Shareholders Agreement can help reduce disputes by setting clear rules around governance, decision-making, and protections for minority shareholders.

2. Using Powers For A Proper Purpose

Directors have powers (for example, to enter contracts, issue shares, and make operational decisions), but those powers must be used for the purpose they’re intended for.

In plain terms: you shouldn’t use your director authority to do something “technically allowed” if you’re doing it for the wrong reason.

A common example is issuing shares. Share issues are a legitimate company tool, but if shares are issued primarily to dilute someone else’s interest unfairly, you can quickly end up in dispute territory.

3. Complying With The Companies Act And The Company’s Constitution

Directors must comply with the Companies Act and (if the company has one) its constitution.

This is one reason it’s worth having clean internal documents and processes from day one - because it makes compliance practical. Things like keeping proper records, passing resolutions correctly, and understanding when shareholder approval is required can all flow from the constitution and the Act.

When you need formal decisions recorded, using (and storing) a proper Directors Resolution helps demonstrate that the director considered the decision and followed the right process.

4. Exercising Reasonable Care, Diligence And Skill

This is a big one for small businesses.

Directors must exercise the care, diligence, and skill that a reasonable director would exercise in the same circumstances - taking into account the nature of the company and the director’s role.

Practically, this often means:

• you stay informed about the company’s financial position (not just “hoping it works out”);
• you don’t sign contracts you haven’t read or don’t understand;
• you ask questions and get advice when something is outside your expertise;
• you keep an eye on compliance risks (tax, employment, privacy, health and safety, industry-specific rules).

It’s not about being perfect - it’s about taking a reasonable, active, responsible approach to running the company.

What Director Decisions Create The Biggest Personal Risk?

Most directors don’t get into trouble because they forgot to file something minor. The bigger risks usually come from a few high-impact areas where director duties and day-to-day business pressure collide.

Trading While Insolvent (Or Close To It)

One of the most serious areas for director liability is continuing to trade when the company can’t pay its debts.

In New Zealand, directors can face consequences if they allow the company to trade in a way that creates a substantial risk of serious loss to creditors (often called “reckless trading”), or if the company incurs obligations it can’t reasonably perform. These risks are commonly assessed by looking at what the director knew (or should have known) about the company’s solvency and cashflow position at the time decisions were made.

For a small business, “insolvency” isn’t always obvious. You might still have sales coming in, but behind the scenes you’re:

• behind on GST or PAYE;
• rolling over supplier invoices;
• only paying creditors when they chase;
• relying on personal loans or credit cards to keep the business afloat.

Note: This is general legal information, not tax or accounting advice. If you’re dealing with GST/PAYE arrears, payment plans, or cashflow concerns, it’s worth getting advice from a lawyer and an accountant early.

If this sounds familiar, it’s a sign you should get advice early. A director who waits until the last moment can end up personally exposed.

Related Party Deals And Conflicts Of Interest

Small businesses often work with family members, friends, and entities you also own - and that’s not automatically a problem.

The risk comes when decisions are made informally, without documenting them, or when the company enters arrangements that aren’t on fair terms (or don’t look fair to an outsider). Directors also need to think about “director interest” rules - including when an interest must be disclosed and recorded, and whether the director should be involved in the decision-making at all (depending on the constitution and the circumstances).

Common examples include:

• the company “loaning” you money without clear terms;
• renting premises owned by you without a written lease;
• paying family members without clear job descriptions or market rates;
• moving company opportunities to another business you own.

These situations are exactly where a director should slow down, document the decision (including disclosures), and ensure the company’s interests are protected.

Signing Contracts Without The Right Authority Or Protections

As a director, you might be the person signing key documents - leases, supplier agreements, funding documents, customer terms, and partnership deals.

Two common pitfalls are:

• Signing personally (or giving personal guarantees) without understanding the consequences; and
• Signing on behalf of the company without the right approvals or proper documentation.

If you’re entering a long-term commitment (like premises), it’s worth getting advice before you sign. A commercial lease can lock your business into years of costs and obligations, so a Commercial Lease Review is often money well spent.

How Do You Actually Comply With Director Duties In Day-To-Day Business?

Knowing director duties is one thing. Building habits that support compliance is what protects you long term - especially when your business is busy, understaffed, or growing fast.

Here are practical ways to meet your obligations as a director without turning your workweek into paperwork chaos.

Keep Basic Governance Records (Even If You’re A One-Person Company)

In small companies, it’s common to make decisions “in your head” and move on. The problem is that if the decision is later questioned (by a shareholder, creditor, liquidator, or regulator), you’ll want evidence of what you decided and why.

Consider keeping:

• director resolutions for major decisions (financing, asset sales, share issues);
• shareholder resolutions where required;
• up-to-date share records;
• signed contracts and variations (in one organised place);
• financial reports and cashflow forecasts (even simple ones).

This is particularly important if your company has multiple owners or you’re planning to bring investors in later.

Know When You Need Shareholder Approval

A director can’t always make every decision alone. Some decisions require shareholder approval, depending on the Companies Act and your constitution.

Examples can include (depending on circumstances and your documents):

• major transactions (like selling substantial assets);
• issuing new shares;
• entering related party transactions in certain structures;
• changing the constitution.

Practically, “shareholder approval” might be required because the Act specifically requires it for that type of decision, because the constitution says it’s needed, or because an earlier shareholder agreement imposes additional consent requirements. If you’re not sure whether a decision needs shareholder sign-off, it’s worth checking before you act - fixing it after the fact is often messier (and can fuel disputes).

Stay On Top Of Cashflow And Solvency

Directors don’t have to be accountants, but you do need a realistic view of whether your company can pay its debts as they fall due.

Practical steps include:

• reviewing cashflow weekly (or more often during tight periods);
• not ignoring tax arrears or payment plans;
• not taking on new obligations without a plan to meet them;
• getting advice early if you’re juggling creditor pressure.

It’s much easier to protect the business (and yourself as a director) when you act early rather than waiting for a crisis.

Use Clear Agreements When Money Or Ownership Is Involved

Director problems often start with unclear arrangements, especially when:

• a co-founder leaves;
• a new investor comes in;
• someone “loans” money to the business;
• shares are transferred informally.

If you’re changing ownership, it’s important that the paperwork matches what the parties agreed. A properly drafted Share Sale Agreement can help make sure the transfer, price, warranties, and handover obligations are clear.

What Other Laws Do Directors Need To Think About (Beyond The Companies Act)?

When you’re a director, your legal responsibilities don’t stop at company law. Running a company also means ensuring the business complies with other legal obligations - and directors are often the people who carry the risk when compliance is neglected.

Depending on your industry, your “director compliance checklist” may include several key areas.

Employment Law And Workplace Compliance

If your company employs staff (even one person), you’ll need to meet employment law obligations. That includes having written employment agreements and meeting minimum entitlements.

For many small businesses, the simplest risk-reducer is getting the basics right from day one, including a fit-for-purpose Employment Contract.

If you don’t, you can end up with disputes that become expensive and time-consuming - and as a director, you’re often the one managing the fall-out.

Privacy And Data Protection

Most businesses collect some form of personal information - customer contact details, online orders, employee records, CCTV footage, mailing lists, and more.

The Privacy Act 2020 applies broadly, and directors should ensure the company takes privacy seriously. That can include having a clear Privacy Policy (especially if you operate online), along with internal practices around data access, storage, and responding to requests or complaints.

Privacy compliance isn’t just “box-ticking”. If something goes wrong (like a data breach), it can quickly damage customer trust and create legal risk.

Health And Safety Duties (If You Have A Workplace Or Staff)

Health and safety obligations can apply even for small teams and low-risk workplaces. Directors should ensure the business is taking reasonable steps to keep workers and others safe.

This might include safe systems of work, training, incident reporting, and contractor management - depending on your operations.

If you’re growing fast and bringing on contractors, labour hire, or new locations, it’s worth checking that your internal policies and contracts keep up with the business.
