How To Register A Business Name In New Zealand And Reserve A Company Name

Picking the right name can feel like one of the most exciting parts of starting a business. It’s the thing you’ll put on your website, your invoices, your social media profiles, and (hopefully) your storefront one day.

But before you go all-in on branding, there’s a practical question you need answered: how do you actually register a business name in New Zealand?

Here’s the catch: in NZ, “business name registration” doesn’t work the same way it does in some other countries. Depending on how your business is structured, you might not “register a business name” as a standalone step - you might instead be registering a company, reserving a company name, and/or protecting the name as intellectual property.

In this guide, we’ll walk you through what “registering a business name” really means in New Zealand, how to reserve your company name, what checks you should do before committing, and how to protect your name from day one.

What Does It Mean To “Register A Business Name” In New Zealand?

When people search for how to register a business name, they’re usually trying to achieve one (or more) of these goals:

• Make the name “official” so they can trade under it confidently
• Stop other people using it (or at least reduce the risk)
• Set up a company so they can operate through a separate legal entity
• Open bank accounts, invoice customers, and sign contracts under a consistent business identity

In NZ, your options depend on your business structure:

If You’re A Sole Trader

If you operate as a sole trader, there’s no Companies Office process to “register a business name” the way you might expect. You can generally trade under your own personal name, or use a trading name.

However, using a trading name doesn’t automatically give you exclusive rights to that name. If name protection matters (and it often does), trade mark protection may be the key step rather than “business name registration”.

If You’re A Partnership

Similar to sole traders, a traditional partnership doesn’t involve reserving or registering a business name with the Companies Office in the same way a company does. You’ll still want to be careful about:

• choosing a name that doesn’t mislead customers
• checking whether someone else already uses a similar name
• agreeing internally on who owns the branding and IP

If you’re going into business with someone else, it’s also worth getting the relationship locked in early with a Partnership Agreement.

If You’re Registering A Company

If you set up a limited liability company, your company name is registered on the Companies Register. This is what most people are referring to when they talk about registering a business name in NZ.

To do this, you typically:

• reserve your company name (so no one else takes it while you’re setting up)
• incorporate your company using that name

If you’re ready to incorporate, getting your structure right from day one matters - including whether you need a Company Constitution and what your founder arrangements look like.

Step-By-Step: How To Register A Business Name (By Reserving And Registering A Company Name)

If your goal is to register a business name by setting up a company, here’s the practical step-by-step process most small businesses follow in New Zealand.

Step 1: Decide Whether You’re Registering A Company Or Just Using A Trading Name

Before you jump into name reservation, decide whether you actually want a company structure.

A company can be a good fit if you:

• want limited liability (your personal assets are generally better shielded from business risks)
• plan to bring on co-founders or investors
• want a structure that can scale more easily
• want to build a business you might sell later

On the other hand, if you’re testing the waters or operating alone, you might start as a sole trader first and incorporate later. There’s no one-size-fits-all answer - it depends on your risk profile, growth plans, and tax/accounting position (it’s usually worth getting tailored advice, including from an accountant or tax adviser on the tax side).

Step 2: Shortlist Names (And Think Beyond Just The Companies Register)

It’s easy to focus only on whether your preferred name is available on the Companies Register. But a “free” company name doesn’t automatically mean:

• you’re not infringing someone else’s trade mark
• the domain name is available
• your social handles are available
• your name won’t create confusion in the market

From a practical branding perspective, it’s usually smart to shortlist 2–3 options and sense-check them across:

• Companies Register
• trade marks database
• domain availability
• social media platforms

This bit can save you a lot of stress later - especially if you’ve already paid for logos, packaging, signage, or marketing campaigns.

Step 3: Reserve Your Company Name In NZ

To reserve a company name in New Zealand, you apply through the Companies Office. The idea is to “hold” the name for a limited period while you complete the incorporation process.

When you apply, you’ll generally need to provide:

• your proposed company name
• your details (or the applicant’s details)
• payment of the relevant fee

Important: reserving a name isn’t the same as incorporating a company. It’s a separate step, and it typically only reserves the name for a set period (so you’ll want to incorporate before it expires).

Step 4: Incorporate Your Company (Register The Company Name)

Once the name is reserved, you can incorporate the company using the Companies Office online process.

At a high level, you’ll usually need to confirm things like:

• company address details
• director details (and director consent)
• shareholder details
• share allocations

This is also the point where a lot of founders realise the name is only one part of setting the business up properly. If you have multiple owners, it’s worth thinking early about what happens if someone wants to leave, someone stops contributing, or you bring in investors - and that’s where a Shareholders Agreement can make a big difference.

Step 5: Use Your Correct Legal Name On Contracts And Invoices

Once incorporated, your company has a legal name (the registered company name). You can still use a trading name for branding, but your legal documents should clearly identify the correct entity.

For example, if your company is “ABC Limited” but your website branding is “ABC Studio”, you’ll want to make sure your:

• invoices identify ABC Limited (often “ABC Studio” as a trading name)
• customer agreements are signed by ABC Limited
• supplier contracts name the correct legal party

This helps avoid disputes about who is actually responsible for paying, delivering services, refunds, and so on.

Also, once you’re up and running, check what business information you’re required to display on documents and communications. For many companies, that can include details like the registered company name and company number (and in some contexts your NZBN), depending on how you trade and what documents you issue.

What Rules Apply When Choosing A Company Name?

When you’re trying to register a company name in NZ, there are rules around what can and can’t be registered, and the Companies Office can decline names that don’t meet requirements.

While the detail can get technical, some common issues include names that are:

• too similar to an existing company name
• misleading (for example, suggesting your business is a government body or has a status it doesn’t)
• offensive or otherwise inappropriate
• restricted due to certain words requiring approval (depending on context)

Also remember: even if the Companies Office approves your company name, you still need to think about how you’ll market the name to the public. Under the Fair Trading Act 1986, your branding and representations to customers must not be misleading or deceptive. This matters for things like:

• claims about what you sell
• suggestions that you’re associated with another business
• how you advertise pricing and “discounts”

If your business sells products or services to consumers, the Consumer Guarantees Act 1993 also impacts how you handle issues like refunds, repairs, and returns (so your customer-facing terms and statements need to align with those obligations too).

Does Registering A Business Name Protect It From Copycats?

This is the big one. If you’re registering a business name (or reserving a company name) because you want to stop other people from using it, it’s important to understand what you are and aren’t getting.

Company Name Registration Is Not The Same As Trade Mark Protection

Registering a company name generally:

• puts your company on the Companies Register under that name
• stops another company from registering the exact (or confusingly similar) company name in many cases

But it doesn’t automatically give you full ownership rights over the brand in the market.

If you want stronger legal protection over your business name, logo, or slogan, you usually need to consider a trade mark registration. This is especially important if you’re investing in branding, packaging, or marketing, or if you plan to grow nationally (or overseas).

It’s also worth thinking about IP ownership internally - for example, if a designer creates your logo or a contractor builds your website, you want to be clear about who owns what. That can be handled through well-drafted contracts and/or an IP assignment.

Don’t Forget Online Assets

From a practical standpoint, you’ll also want to lock in the basics:

• your domain name (and common misspellings if relevant)
• social media usernames
• Google Business profile name (if you’ll have a physical presence)

These steps don’t replace legal protection, but they reduce the risk of confusion and help you build a consistent brand identity.

What Else Should You Set Up Once You Register Your Business Name?

Getting the name sorted is a great milestone, but it’s only one piece of getting your legal foundations right.

Once you register your business name (or your company name), here are some common next steps that help protect your business as you start trading.

1) Put The Right Agreements In Place

If you’re providing services, you’ll usually want a written contract (or strong terms and conditions) that covers things like payment terms, scope, delays, cancellations, and liability.

If you’re hiring staff, you’ll also need proper documentation and processes. A good Employment Contract is a practical way to set expectations around duties, pay, hours, confidentiality, and termination rights.

If you’re engaging contractors, the agreement should clearly set out deliverables, IP ownership, and confidentiality, and it should be consistent with how the working relationship actually operates.

2) Get Your Privacy Settings Right

If you collect personal information - even something as simple as customer names, emails, delivery addresses, or enquiry forms - you need to think about the Privacy Act 2020.

Most businesses that collect customer data online should have a Privacy Policy that explains what you collect, why you collect it, how you store it, and how customers can request access or corrections.

Privacy compliance is one of those “set it up early and forget about it” steps that can save you major headaches later, especially as your customer list grows.

3) Make Sure Your Advertising And Customer Terms Stack Up

Once you’re trading under your business name, the way you describe your products and services matters.

For example, if you run an online store, your website wording, refund policy, and checkout terms should align with NZ consumer law. If you offer promotions or discounts, you need to ensure those claims are accurate and not misleading.

It’s often worth having properly drafted Website Terms And Conditions (or ecommerce terms) so you’ve got clear rules for orders, delivery, chargebacks, cancellations, and liability limits.

4) Consider Your “Future You” Problems

Here’s a scenario we see all the time: you and a friend start a business with a great name, you split things “50/50”, and you get going quickly. Six months later, one of you is doing most of the work, or someone wants out, or a new investor wants in - and suddenly there’s confusion about decision-making and ownership.

That’s why it’s smart to tackle founder and ownership documents early, while everyone’s still aligned and excited about building the business.

Key Takeaways

• In New Zealand, “registering a business name” often means reserving and registering a company name through the Companies Office, rather than a separate “business name registration” system.

• To reserve a company name in NZ, you generally apply to reserve the name first, then incorporate your company before the reservation expires.
• Registering a company name can help with legitimacy, but it does not automatically protect your brand the way a trade mark can.
• When choosing and using your name, make sure your branding and advertising are accurate and not misleading, especially under the Fair Trading Act 1986 and (if you sell to consumers) the Consumer Guarantees Act 1993.
