Law & accounting guide

Business law basics in NZ

The legal essentials every New Zealand business owner should understand: how contracts work, what governance and directors' duties mean, and the obligations you carry just by being in business.

Most people start a business focused on the product and the customers, and the legal side only becomes urgent after a problem. That is backwards. The basics are not complicated, and understanding them prevents most of the expensive surprises. This guide covers the three that matter most.

Contracts: the plain rules that make them work

A contract does not need to be a formal, lawyer-drafted document to be real. In New Zealand a contract exists when there is a clear agreement, something of value passing between the parties, and a genuine intention to be bound. The practical rules that keep you safe:

The honest view on lawyers here: you do not need one for every purchase order, but for the contracts that underpin your business, the fee for a review is cheap insurance against signing something you do not actually understand.

Governance and directors' duties

If you run a company, you carry duties that go beyond running the day to day. Corporate governance is the framework of rules and duties that decides how the company is run and who is accountable, and the responsibilities that land on directors are real:

Worth noting

Directors' duties are one of the places where the difference between a company and being a sole trader shows up most sharply. A sole trader carries personal risk on everything the business does. A company limits some of that personal exposure, but it replaces it with a heavier set of formal obligations. The structure question is covered more in the services guide.

The obligations you carry as a business owner

Beyond contracts and governance, every business carries a set of standing obligations, whether you are a sole trader or a company:

These standing obligations are why a little professional support early is usually a poor place to economise. A single overlooked filing, an unread clause, or a privacy lapse can cost far more than the modest fee an accountant or lawyer would have charged to catch it. The businesses that get into real legal trouble are rarely the ones that worried about the rules and asked questions; they are the ones that treated compliance as a problem for later. Later shows up, and it is always more expensive then.

The point

Business law in New Zealand comes down to a few honest rules: make your contracts clear and in writing, understand the duties you take on when you run a company, and meet your standing obligations to tax, customers and staff. None of it is exotic, but all of it is expensive to ignore. When in doubt, confirm the current position with a lawyer or accountant.

Common questions

Business law basics: asked and answered

What obligations do I have as a business owner in New Zealand?

Every business carries obligations around tax, record keeping and how it treats customers and staff. If you run a company, you also take on directors' duties, which means acting in the company's interests and meeting your filing and reporting obligations on time.

How do I make a contract enforceable?

A contract needs a clear agreement between the parties, something of value exchanged, and a genuine intention to be bound. Getting it in writing with the key terms spelled out makes it far easier to enforce, and having a lawyer review important contracts is usually worth the cost.

What is corporate governance?

Corporate governance is the framework of rules and duties that governs how a company makes decisions and who is accountable for them. It covers directors' duties, keeping proper records, and running decision making properly, so the company operates fairly and stays compliant.

Do I need to keep company records?

Yes. Companies have to keep proper accounting records that show their financial position, and there is a legal duty to keep them up to date. Good records protect you, make tax and reporting easier, and are a legal requirement rather than an option.
