Passing Off Law in New Zealand

You do not need a registered trade mark to run into a branding dispute in New Zealand. A business can still complain that your name, logo, packaging, website wording or social media presence is too close to theirs, even if they never registered formal rights. This is where passing off law often comes up, and founders usually get caught by a few avoidable mistakes.

The common problems are choosing a brand name because the Companies Office allowed it, assuming a small design tweak makes a copy safe, and launching online before checking how customers might actually read the branding. Another frequent mistake is waiting until after packaging, domains, signage and ad spend are locked in before doing any legal checks.

This guide explains what passing off law means in New Zealand, when it becomes a real business risk, what a claim usually turns on, and the practical steps to take before you spend money on setup, marketing or a rebrand.

Overview

Passing off law protects business goodwill where one trader misrepresents its goods or services as being connected with another. In plain terms, the question is whether your branding or conduct is likely to mislead customers into thinking there is some link, endorsement or shared source when there is not.

A passing off claim usually depends on whether the other business has goodwill, whether there has been a misleading representation, and whether damage has happened or is likely to happen.

• Check whether a similar business already has a market reputation in New Zealand.
• Compare the full customer impression, not just the exact business name.
• Review logos, packaging, slogans, domain names, social handles and ad copy together.
• Remember that company name registration does not give you a free pass.
• Consider related claims too, especially under the Fair Trading Act and trade mark law.
• Sort out contracts, IP ownership and clearance checks before you print, launch or rebrand.

What Passing Off Law Means For New Zealand Businesses

Passing off law is a business reputation claim. It is designed to stop one trader from gaining an advantage by creating confusion about another trader's identity, products or services.

In New Zealand, passing off sits alongside other legal rights, especially registered trade marks and the Fair Trading Act 1986. A business may rely on one of these routes or use them together, depending on the facts.

The basic idea in plain English

If customers are likely to think your business is the same as, associated with, endorsed by or supplied by another business, that can create a passing off problem. The issue is not limited to deliberate copying. You can create legal risk even if the similarity was accidental.

This matters for startups and SMEs because branding decisions are often made quickly. A founder picks a name, a designer creates a logo, packaging is ordered, a website goes live and paid ads start running. If the brand is too close to someone else, the legal and commercial cost can be high.

What a claimant usually needs to show

Passing off claims are often discussed using three core elements. The precise legal framing can vary, but these are the practical points most businesses need to understand.

1. Goodwill: The other business must have an established reputation or customer connection in the relevant market. This is about real commercial recognition, not just an idea for a brand.
2. Misrepresentation: Your branding or conduct must be likely to mislead customers into believing there is a connection between the two businesses.
3. Damage: The claimant must show actual or likely harm, such as lost sales, diluted brand value, damaged reputation or interference with expansion plans.

Goodwill is often the first pressure point. A business with a small but real reputation in a niche market may still have protectable goodwill. On the other hand, a business with no real customer recognition may struggle to rely on passing off alone.

What counts as a misleading representation

The law looks at the overall impression on the relevant customers. That means courts and lawyers do not just compare names side by side like a spelling quiz. They look at how people encounter brands in the real world.

That can include:

• business names and trading names
• logos and colour schemes
• product packaging and labels
• website layout and app presentation
• social media usernames and profile branding
• taglines and advertising copy
• store fit-out or get-up
• claims about history, location, partnerships or origin

A disclaimer is not always enough. If the first impression already misleads people, a small line of clarifying text may not fix the problem.

How passing off differs from trade mark infringement

A registered trade mark gives statutory rights. Passing off is different because it relies on reputation and misleading conduct rather than registration alone.

This is where founders often get caught. They search the Companies Register, see a name is available, register a company and assume they are safe. Company registration and business name use are not the same thing as having trade mark clearance or being free from a passing off claim.

Trade mark registration can make enforcement easier, but it is not the only source of rights. An established unregistered brand may still have enough goodwill to bring a passing off case.

Why this matters beyond product businesses

Passing off is not just about labels on shelves. It can affect service businesses, tech startups, agencies, consultants, online platforms, retailers, hospitality operators and franchised businesses.

Common situations include a new consultancy using a name similar to an existing firm, an online store adopting packaging that looks like a known local brand, or a startup suggesting affiliation with an industry partner it does not actually have. The legal risk grows when the overlap affects the same customers, channels or region.

When This Issue Comes Up

Passing off issues usually appear at moments of growth, launch or conflict. The risk tends to surface when a business is moving fast and branding decisions are made before proper checks.

Choosing a business or brand name

The classic trigger is name selection. You might find a company name available through the Companies Office and think that means it is safe to use in trade. It does not. The real question is whether another business already has enough reputation that your use could confuse customers.

This is particularly common when founders use descriptive words, local references or minor spelling changes. A one-letter difference may still sound identical when spoken, and customers often remember the gist of a brand rather than the exact wording.

Launching online or selling through marketplaces

Online trading can increase confusion quickly. Search results, paid ads, marketplace listings and social media recommendations can place similar brands side by side. If your name or visual identity resembles another business, customers may assume they have found the same supplier.

Before you launch online, review:

• domain names
• social media handles
• app store names
• website headings and metadata
• product listing titles and images
• influencer and affiliate marketing materials

Digital marketing can also create problems if ads target a competitor's brand in a way that implies affiliation or official status.

Packaging, labelling and product get-up

Packaging disputes often turn on the overall look and feel rather than one exact feature. A similar bottle shape, label arrangement, colour palette and product description can create the impression that goods come from the same source or a related source.

This matters before you print at scale. Once stock is manufactured and shipped, changing branding can be expensive and disruptive.

Rebrands, collaborations and distributor arrangements

Risk also appears when a business expands or changes direction. A rebrand can drift too close to a competitor. A collaboration campaign can overstate the relationship between two businesses. A distributor or reseller might use branding in a way that suggests exclusivity or endorsement that has not been agreed.

Before you sign a contract, make sure brand use is clearly covered. Distribution agreements, reseller terms, agency arrangements and influencer agreements should say exactly how names, logos and claims can be used.

Exits from employment, partnerships or franchises

Another common flashpoint is when a person leaves a business and starts a competing operation with similar branding or messaging. Customers may believe they are dealing with the old business, a successor, or an authorised branch.

These situations often involve a mix of issues, including confidential information, restraints, ownership of branding assets and client communications. Passing off can become one part of a larger commercial dispute.

Practical Steps And Common Mistakes

The best protection is to clear your brand properly before launch and document ownership from the start. Once confusion is in the market, fixing it is harder and more expensive.

Do more than a company name search

A Companies Office search is only one small step. Before you spend money on setup or company setup, check the wider market position.

Your review should include:

• registered trade marks in relevant classes
• existing unregistered businesses using similar names
• domain names and social media presence
• industry directories, app stores and marketplace listings
• whether similar brands target the same customers or locations
• whether the name sounds alike when spoken aloud

If your business plans to sell online across New Zealand, a narrow local check is not enough. If you plan to export, overseas rights may matter too.

Look at the whole brand, not one asset in isolation

Founders often focus only on the word mark. The actual risk may come from the combination of name, logo, colours, packaging and claims.

For example, a generic name might be manageable on its own, but not when paired with packaging that copies a known market style. A new logo may also create issues if it reinforces similarity rather than reducing it.

Register trade marks where appropriate

Trade mark registration is not mandatory, but it is often a sensible step. It can strengthen your position if someone later copies your brand, and it can help flush out conflicts before you invest heavily in a launch.

Registration strategy depends on what you are actually using. Some businesses should protect the name first. Others may also need logo marks, product line names or slogans. The right filing scope depends on your goods or services and expansion plans.

Trade mark registration does not replace good branding discipline. You still need consistent use, proper ownership and sensible marketing claims.

Make sure your contracts deal with IP ownership and use

Brand disputes sometimes start inside the business, not outside it. If a freelance designer, agency, web developer or co-founder created the branding, ownership should be clearly documented.

Check that your agreements cover:

• who owns the name, logo, artwork and content
• whether assignments have been signed
• who can approve changes to branding
• how contractors can use your brand in portfolios or case studies
• what happens if a rebrand is needed after launch

Without clear contracts, you can end up with two problems at once, a third party claim and an internal ownership dispute.

Avoid marketing claims that imply affiliation

Passing off is not limited to similar names. Your advertising can create the same issue if it suggests a relationship that does not exist.

Watch for statements and imagery that imply:

• official partnership or endorsement
• authorised reseller status
• shared ownership or common group branding
• origin from a better-known supplier
• legacy, history or continuation of another business

This also overlaps with the Fair Trading Act. If your marketing is misleading or deceptive, you may face more than one legal route of complaint.

Act early if you receive a complaint

A letter of demand does not automatically mean the other side is right, but ignoring it is rarely a good idea. The facts matter, and early responses often shape whether the issue becomes a quick commercial resolution or a long dispute.

When a complaint lands, gather the key materials first:

• your branding files and launch dates
• trade mark records
• evidence of your searches and clearance steps
• examples of how customers encounter your brand
• any customer confusion complaints, comments or misdirected enquiries
• relevant contracts with designers, agencies, distributors or resellers

You may decide to hold a launch, adjust branding, negotiate coexistence, or get a contract review before defending your position. The right response depends on the strength of the other business's goodwill, the degree of similarity and the likely commercial damage.

Common mistakes founders make

Most passing off problems are not caused by obvious copying. They come from rushed assumptions.

• Assuming company registration means legal clearance.
• Relying on a quick internet search and stopping there.
• Choosing a name that sounds too close to a known competitor.
• Copying a successful market look while changing only minor details.
• Letting a designer or marketer create branding without legal review.
• Using claims like “official”, “authorised” or “partner” too loosely.
• Failing to assign IP from founders or contractors to the company.
• Waiting until packaging, ads and signage are paid for before checking risk.

These are all fixable early. They become expensive after launch.

FAQs

Do I need a registered trade mark to bring a passing off claim?

No. A business may rely on passing off if it has sufficient goodwill and can show misleading conduct and likely damage. A registered trade mark can still be very helpful, but it is not the only basis for a complaint.

Can I use a business name if the Companies Office let me register it?

Not necessarily. Company registration does not confirm that the name is safe from trade mark or passing off issues. You still need to consider existing market reputation and customer confusion.

Does passing off only apply when two names are identical?

No. Similar sounding names, lookalike logos, packaging, website design or marketing claims can all contribute to a misleading impression. The overall customer takeaway matters most.

What if I did not mean to copy another brand?

Intent can matter in some disputes, but accidental similarity can still create legal risk. The main question is whether customers are likely to be misled, not whether the conduct was deliberate.

What should I do before a new brand launch?

Clear the name and visual branding, review trade mark availability, check online use, confirm IP ownership in contracts and assess whether any marketing language implies a relationship that does not exist. Doing this before you print, advertise or sign supply arrangements or customer terms can save a lot of cost later.
