Choosing A Company Name In New Zealand: Legal Checks, IP Risks And Steps

Picking a company name is one of the most exciting parts of starting a business. It’s the name you’ll put on your website, invoices, packaging, social media, and (hopefully) a growing list of happy customer reviews.

But it’s also one of the easiest places to get tripped up.

In New Zealand, the “right” company name isn’t just the one that sounds good. You’ll also want to check whether it’s available for registration, whether it might infringe someone else’s intellectual property (IP), and whether it could create issues under New Zealand’s advertising and consumer rules.

Below, we’ll walk you through the key legal checks, common IP risks, and the practical steps to register your company name properly - so you can build your brand with confidence from day one.

What’s The Difference Between A Company Name, Trading Name And Brand?

Before you do any checks or registrations, it helps to get the terminology straight - because in New Zealand, these labels can get confusing quickly.

Company Name

Your company name is the legal name of your company recorded on the Companies Register. If you incorporate a company, it’s the official name of that legal entity (and it’s the name you’ll use in many legal and administrative contexts, even if you trade under a different name).

If your company is registered as a limited liability company, its name must include “Limited” (or “Ltd”).

Trading Name

A trading name is the name you use publicly in the market. You might operate with a trading name that’s different from your company name (for example, if you want a shorter name for branding).

Important point: using a trading name doesn’t automatically give you exclusive rights to it. If you want stronger protection, you typically need to look at trade marks and broader brand protection strategies.

Brand (And Your IP)

Your “brand” often includes things like:

• your business name (company name and/or trading name)
• logos and designs
• taglines and product names
• domain names and social handles

Some parts of your brand can be protected through intellectual property rights (especially trade marks), which can matter a lot if you’re planning to scale, franchise, or sell your business down the track.

If you’re also working out how to structure your business at the start, it’s worth thinking about whether you’ll need a Company Constitution early on (particularly if you’ll have multiple founders or shareholders).

How Do I Check If A Company Name Is Available In NZ?

It’s tempting to fall in love with a name first and “figure out the legal stuff later” - but doing your checks early can save you a costly rebrand.

When checking if a company name is available, you’ll want to consider three different kinds of “availability”:

• Companies Register availability (can you register that company name?)
• Trade mark availability (could someone stop you using it?)
• Market availability (is it already being used in a confusing way?)

1) Check The Companies Register

If you’re registering a company, the Companies Office may refuse a proposed name in certain situations - for example, where it’s identical (or almost identical) to an existing name on the register, is offensive, or is likely to mislead (such as implying a connection to government or a regulated industry where that’s not true).

This step is important, but it’s not the whole story. Even if the Companies Office accepts the name, that doesn’t guarantee you’re safe from IP disputes.

2) Check Trade Marks (This Is The Big One)

In practice, trade mark conflicts are one of the biggest risks when choosing a company name - because a registered trade mark owner may have the legal right to stop you using the same name (or a confusingly similar name) for the same or similar goods or services.

That’s why it’s smart to do trade mark checks early, especially if you’re:

• investing in branding, packaging, or signage
• launching an online store
• planning to grow beyond a small local customer base
• raising money or bringing in co-founders

If you’re setting up with more than one founder, it’s also a good time to think about how you’ll manage ownership and decision-making with a Shareholders Agreement, so your company’s growth doesn’t turn into a governance headache later.

3) Check Domains And Social Handles

This isn’t strictly a legal check, but it’s a practical one that can become a legal and commercial headache if you ignore it.

If your company name is available but the matching domain name is taken (or a close alternative is being used by a competitor), you might end up with:

• customer confusion
• missed website traffic
• a name you can’t build long-term brand equity in

What Are The Legal Risks If My Company Name Is Too Similar To Someone Else’s?

Choosing a company name that’s “close enough” to someone else’s can cause real problems, even if you didn’t mean to copy anyone.

Here are the main legal risks business owners usually run into.

Trade Mark Infringement

If your company name (or the way you use it) is the same as, or confusingly similar to, someone else’s registered trade mark for the same or similar goods or services, you could face trade mark infringement issues.

This can lead to things like:

• cease-and-desist letters
• being forced to rebrand (including changing your domain and marketing materials)
• legal costs and business disruption

Even if you successfully register your company name, that doesn’t override a trade mark owner’s rights.

Fair Trading Act Issues (Misleading Or Deceptive Conduct)

Even without a registered trade mark, there are still risks under the Fair Trading Act 1986. Broadly, New Zealand businesses must not engage in misleading or deceptive conduct (or conduct likely to mislead or deceive).

If your company name suggests you’re connected to another business, a particular qualification, or an endorsement that isn’t true, that can create exposure under the Fair Trading Act - especially if customers are likely to be confused.

“Passing Off” And Reputation-Based Claims

There are also common law risks (including “passing off”) where a name is used in a way that misrepresents a connection with another business and causes (or is likely to cause) harm to that other business’s goodwill or reputation. These kinds of claims often come down to whether customers are likely to be misled into thinking the businesses are connected.

These disputes can be time-consuming and expensive, which is why name checks are one of those “do it once, do it right” steps.

Customer Confusion And Commercial Damage

Not every risk is a courtroom risk. A similar company name can cause:

• customers contacting the wrong business
• bad reviews meant for someone else landing on your pages
• difficulty running online ads or social campaigns
• problems with suppliers, banks, or payment providers verifying your business

These issues can slow your growth even if no one ever formally complains.

Step-By-Step: How To Choose And Register Your Company Name

Once you’ve got a short list of names, here’s a practical process you can follow.

Step 1: Narrow Your List And Sense-Check The Name

Start with a shortlist (usually 3–5 options). Then ask:

• Is it easy to spell and say out loud?
• Will it still fit if you expand into other products or regions?
• Could it be misunderstood (for example, implying a service you don’t provide)?
• Does it unintentionally include restricted words like “bank”, “trust”, or “royal”?

Step 2: Do The Availability Checks (Register + Trade Mark + Online)

At this stage, do your core checks:

• Companies Register name availability
• Trade mark search checks for the same or similar names
• Google search and social media checks (for real-world use)
• Domain checks for .co.nz and any key variations you want to secure

If you’re unsure whether a similar name is “too close,” it’s worth getting tailored legal advice. The line between “fine” and “legally risky” often depends on context - including industry overlap and how customers are likely to interpret the name.

Step 3: Reserve The Company Name

In New Zealand, you can usually reserve a company name through the Companies Office before you fully incorporate. This helps hold the name while you finalise your setup.

Keep in mind that reserving a name is not the same as owning the brand from an IP perspective - it’s more like holding a spot on the Companies Register while you complete incorporation.

Step 4: Register Your Company (If A Company Is The Right Structure)

Registering a company is a separate decision from choosing a company name. You might be operating as a sole trader or partnership instead - and in those cases, your “company name” won’t exist because you’re not actually incorporated.

If you are incorporating, make sure you think through the broader setup, including governance, ownership, and ongoing compliance. Many growing businesses also adopt a constitution to set clear rules early - and it’s often easier to do this upfront than to retrofit it later. (A Company Set Up done properly can make a big difference as you scale.)

Step 5: Consider Registering A Trade Mark For The Name

If your business name is central to your branding (and for most businesses, it is), registering a trade mark can be one of the strongest ways to protect it.

Trade marks can help you:

• stop others from using confusingly similar names
• build a real asset in your brand (useful if you sell the business later)
• reduce the risk of someone else trade marking “your” name after you’ve invested in it

Trade mark strategy isn’t one-size-fits-all. It often depends on what you sell, where you sell it, and what parts of your branding you want to protect (name only, logo, slogan, etc.). If you want to protect the name properly, Register Your Trade Mark with the right classes and a clear filing strategy.

Step 6: Align Your Documents And Public-Facing Materials

Once you’ve settled the name, make sure your legal and operational setup matches it. That includes:

• your website footer and contact details
• invoicing details (especially where your legal entity name must appear)
• customer terms (if you sell online or provide services)
• supplier agreements and contractor agreements

If you’re collecting personal information through your website (for example, customer orders, email newsletters, enquiry forms), you’ll also want a properly tailored Privacy Policy so you’re meeting your obligations under the Privacy Act 2020.

Common Mistakes When Choosing A Company Name (And How To Avoid Them)

We see the same issues pop up for small business owners again and again - usually because the naming stage feels “creative” rather than “legal.”

Here are a few common traps to watch out for.

1) Assuming A Company Name Registration Gives You IP Rights

Registering a company name is important, but it doesn’t automatically give you exclusive rights to use that name in the market.

If someone else owns a trade mark, they may still be able to object to your use of the name (even if your company is already incorporated).

2) Only Checking Exact Matches

It’s not just exact matches that can cause problems.

Many disputes are about names that are:

• spelled differently but sound similar
• visually similar (especially in logos)
• similar enough that customers might assume there’s a connection

3) Picking A Name That’s Too Descriptive

Names that are purely descriptive can be harder to protect as a brand (and sometimes harder to trade mark). From a marketing perspective, descriptive names can also be tough to stand out with online.

This doesn’t mean you can’t use descriptive words - but it’s worth thinking about whether your name has something distinctive that customers will remember.

4) Forgetting About Future Growth

A name that works for a local service might not work when you expand nationwide, move online, or bring on investors.

Imagine this: you’ve spent two years growing your business, and now you’re ready to expand - but you discover a similar brand is already established in the new region, or someone has registered the trade mark in a way that blocks you. That kind of issue is much easier (and cheaper) to avoid at the start.

5) Not Setting Up Your Legal Foundations Alongside The Name

Your company name is only one part of your legal setup. If you’re hiring, selling products online, working with contractors, or entering supplier relationships, you’ll usually need legal documents that match how your business actually operates.

For example, if you’re employing staff, a clear Employment Contract can help protect your business and set expectations from day one.

And if you’re running an e-commerce store, having fit-for-purpose website terms (alongside your privacy compliance) matters just as much as having the right name.

Key Takeaways

• Your company name is your legal entity name on the Companies Register, but it’s not the same thing as a trading name or a protected brand.
• Before committing to a company name, you should check Companies Register availability, trade marks, and real-world use (including domains and social media handles).
• Registering a company name doesn’t automatically protect you from trade mark disputes, Fair Trading Act issues, or reputation-based claims like passing off.
• A practical naming process includes shortlisting, doing legal/IP checks, reserving the name, registering the company (if appropriate), and considering trade mark protection.
• It’s worth thinking about your wider legal setup at the same time - including governance documents, contracts, and privacy compliance - so you’re protected from day one.
