How Do You Protect Your Slogan Or Tagline From Your Competitor? (2026 Updated)

Your slogan (or tagline) can be one of the most valuable parts of your brand. It’s the line people remember, repeat, and search for when they’re ready to buy.

That’s also why competitors sometimes “borrow” it - or get uncomfortably close.

This (2026 updated) guide walks you through the practical, NZ-specific ways to protect your slogan or tagline, what legal rights you can (and can’t) rely on, and what to do if a competitor copies you.

What Legal Protection Can A Slogan Or Tagline Have In New Zealand?

A slogan usually isn’t protected in just one way. In New Zealand, protection tends to come from a mix of:

• Trade mark law (often the strongest option for slogans)
• Fair trading and misleading conduct rules if a competitor’s use confuses customers
• Copyright (sometimes, but usually limited for short phrases)
• Contract protections (with staff, agencies, freelancers) to stop “leaks” or re-use
• Brand strategy (consistent use and evidence, which matters in disputes)

The key thing to know is: you don’t automatically “own” a slogan just because you thought of it first. Ownership and enforceability depends on what rights you’ve built around it - especially whether you’ve registered it as a trade mark and how you use it in market.

What Counts As A “Slogan” For Legal Purposes?

In practice, a “slogan” or “tagline” is just a short brand phrase - like a marketing line used:

• on your website and social media
• in ads and packaging
• in email signatures and sales material
• on signage, uniforms, or vehicles

If it’s used to identify your business (not just as a one-off marketing line), it’s much more likely to be protectable as a trade mark.

Is Registering A Trade Mark The Best Way To Protect A Tagline?

In most cases, yes - trade mark registration is the cleanest and most enforceable way to protect a slogan in New Zealand.

A registered trade mark gives you exclusive rights to use that slogan as a trade mark for the goods/services you register it for. That means if someone uses the same (or confusingly similar) slogan in the same commercial space, you have a much clearer path to enforcement.

In a dispute, it’s often the difference between:

• “This feels unfair” (harder to enforce), and
• “This infringes our registered rights” (much stronger position).

When Is A Slogan Registrable As A Trade Mark?

Not every phrase can be registered. Generally, slogans are easier to register if they’re:

• distinctive (unique to you, not something everyone in the industry uses)
• not purely descriptive (e.g. “Best Coffee In Auckland” is likely too generic)
• not misleading (e.g. claiming qualities you can’t back up can create problems under the Fair Trading Act 1986)
• not too close to an existing trade mark in your category

Distinctiveness matters because trade marks exist to identify a single trade source. If your slogan is basically a common phrase, it’s harder to argue that customers associate it only with you.

Should You Register The Slogan Alone Or With Your Logo?

This is a strategic decision, and it’s one area where tailored legal advice is worth it.

• Slogan as words only: usually gives broader protection, because it covers the words regardless of stylisation.
• Logo version: can be useful if the words alone aren’t distinctive enough, but it may narrow protection to that particular design.

Many businesses register both over time, especially if the slogan becomes a key part of the brand.

What If You Haven’t Registered Yet?

Don’t stress - you might still have options (we’ll cover them below). But if the slogan is central to your brand, registering early is one of the best “protect your business from day one” moves you can make.

If you’re reviewing your broader brand protection (not just a slogan), it can also help to consider how your tagline sits with your overall trade mark strategy and any licensing arrangements you might need later, like an IP Licence.

What Other Laws Help If A Competitor Copies Your Tagline?

Even without a registered trade mark, New Zealand law can still give you tools - particularly where the competitor’s use could mislead customers.

Fair Trading Act 1986: Misleading Or Deceptive Conduct

The Fair Trading Act 1986 (FTA) broadly prohibits misleading or deceptive conduct in trade.

In slogan disputes, this can matter when a competitor uses a similar tagline in a way that:

• makes customers think their business is connected to yours
• creates confusion about who is providing the goods/services
• piggybacks off your reputation

This is especially relevant if you’ve built strong market recognition and can show consumers associate the phrase with you.

Passing Off: Protecting Your Brand Reputation

“Passing off” is a common law claim (not a statute) that can apply where someone misrepresents their goods/services as being yours, or connected to you, and that harms your goodwill.

It tends to be more complex and evidence-heavy than trade mark infringement - but it can be helpful where your brand has real market traction and a competitor is trying to ride on it.

Copyright: Usually Limited For Short Phrases

A lot of business owners assume copyright automatically protects their slogan. In reality, copyright protection for short phrases is often limited, because copyright generally protects original “works” (like written content, designs, images) and not simple, common, or very short expressions.

If your “slogan” is actually a longer piece of original copy (or part of a broader creative work), copyright might be more relevant. But for most taglines, trade marks and fair trading protections are the more practical focus.

How Do You Reduce The Risk Of Someone Else Claiming Your Slogan?

Protecting your slogan isn’t only about stopping a competitor from copying you. It’s also about avoiding the nightmare scenario where you get accused of infringement after you’ve invested in marketing, packaging, and signage.

A good protection plan usually includes both legal checks and operational steps.

1) Do A Clearance Search Before You Commit

Before you print, launch, or spend serious money on ads, do checks such as:

• searching the NZ trade marks register for identical and similar phrases
• checking close competitors in your industry
• looking at domain names and social media handles (not determinative legally, but a practical red flag)

This is where many businesses trip up: a phrase can feel “original” but still be too close to someone else’s trade mark in the same class of goods/services.

2) Use Your Slogan Consistently (And Keep Records)

If you ever need to prove your reputation or show consumer recognition, evidence matters. It helps to keep:

• dated screenshots of your website and social pages
• copies of ads, brochures, packaging, and invoices
• campaign documents showing when the slogan was launched and used
• customer messages or reviews referencing the slogan

This kind of record-keeping can be invaluable if you’re relying on the Fair Trading Act or passing off, or if you need to show the history of your brand use during a dispute.

3) Lock Down Ownership Internally (Employees, Contractors, Agencies)

Sometimes the competitor copying your tagline isn’t a random competitor at all - it can happen after a staff member leaves, a contractor re-uses assets, or a marketing agency repurposes concepts across clients.

Make sure your agreements clearly cover:

• who owns brand assets and marketing collateral
• confidentiality obligations
• how intellectual property created during the engagement is assigned to you (where appropriate)

If you hire staff to build your brand, your Employment Contract is a good place to deal with confidentiality and IP created in the course of employment.

If you outsource work (designers, marketers, copywriters), having the right terms in place early can save you a lot of dispute risk later - it’s similar to the reason businesses put proper Service Agreement terms in place with suppliers and contractors rather than relying on informal emails.

4) Make Sure Your Advertising Claims Stack Up

Slogans often include bold claims (“fastest”, “#1”, “guaranteed results”, “cheapest”). Even if you’re focused on competitor risk, you also need to think about whether your tagline could create compliance risk under the Fair Trading Act 1986.

If your slogan could be read as a factual claim, you should be able to substantiate it.

This is also part of overall consumer law hygiene - the same ecosystem that affects refund messaging and product claims under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986.

What Should You Do If A Competitor Starts Using Your Slogan?

When you spot a competitor using your slogan (or something very close), it’s tempting to jump straight to a public call-out. In practice, that often escalates things and can make resolution harder.

A calmer, more strategic approach usually works better.

Step 1: Confirm What They’re Actually Doing

Start by gathering evidence:

• screenshots of their website and ads (with dates)
• photos of signage, packaging, or promotional material
• where and how the slogan is being used (headline, logo lockup, product name, etc.)

Also note whether their slogan is identical, or just similar. The legal analysis often turns on likelihood of confusion and the context of use.

Step 2: Check Your Rights (Registered And Unregistered)

Ask:

• Do you have a registered trade mark for the slogan (or a similar mark)?
• Are they using it for goods/services that overlap with yours?
• Have you built recognition in the market so consumers associate the tagline with you?
• Is their use likely to mislead customers?

If you have a registered trade mark, enforcement is usually more direct. If not, you may still have strong arguments under the Fair Trading Act 1986 and passing off - but it often depends on evidence and how established your brand is.

Step 3: Decide Your Commercial Goal Before You Write Anything

Before contacting them, get clear on what outcome you want:

• Do you want them to stop entirely?
• Would you accept them using a modified version?
• Is this a one-off local operator issue, or a direct competitor targeting your customers?
• Do you want a short transition period (e.g. to update signage)?

Being clear on the goal makes your communications much more effective.

Step 4: Send A Well-Drafted Cease And Desist (Or Negotiation Letter)

Often the next step is a letter setting out your rights and what you want them to do. This can be positioned as:

• a firm cease and desist, or
• a commercial negotiation to resolve the issue quickly.

It’s worth getting legal help here. These letters can have real consequences, and an overly aggressive (or poorly grounded) letter can backfire.

Step 5: Consider Longer-Term Brand Protection If This Is A Bigger Pattern

If you keep seeing imitation (not just for the slogan), it can be a sign your brand has reached a level where you need tighter legal foundations across the board - such as cleaning up IP ownership, strengthening customer-facing terms, and ensuring internal documents match how you actually operate.

For example, if you run a digital business and the slogan is tied closely to your online presence, it’s also smart to ensure your website legals are consistent and up to date, including a properly drafted Privacy Policy if you collect personal information.

How Do You Build A Strong “Brand Protection System” Around Your Slogan?

A slogan rarely sits on its own. It usually forms part of a bigger brand system: your name, logo, product names, tone of voice, and customer experience.

If you want to protect your slogan in a way that’s practical (not just theoretical), it helps to treat it as part of your legal foundations.

Register And Document Your Key Brand Assets

Depending on your business, that might include:

• your business name and trading name
• your logo
• your slogan/tagline
• product or service names
• domain names and key social handles

Registration doesn’t replace real-world use - but it makes enforcement clearer and often faster.

Make Sure Your Business Structure Supports Ownership

As your business grows, you might bring in a co-founder, investors, or new directors. It’s important that everyone is clear on who owns what - including brand assets.

If you run a company, the internal rules (and shareholder arrangements) should line up with how decisions get made and how IP is controlled. This is often where a Company Constitution and a Shareholders Agreement can reduce disputes later - especially if someone exits and there’s disagreement about who can use the brand.

Use Contracts To Stop “Soft Copying” (Not Just Exact Theft)

In real life, competitors don’t always copy your tagline word-for-word. Sometimes they copy the “concept”, cadence, or campaign theme - especially when someone involved in your marketing later works with them.

That’s why confidentiality and IP clauses in your key agreements matter. They won’t stop all competitor behaviour, but they can stop a lot of the most common leakage points.

Key Takeaways

• Trade mark registration is usually the strongest way to protect a slogan or tagline in New Zealand, because it gives clearer rights and stronger enforcement options.
• The Fair Trading Act 1986 and passing off can still help if a competitor’s use of a similar slogan is likely to confuse customers or piggyback on your reputation.
• Copyright protection for slogans is often limited, because short phrases are not always protected as “works” in the way people assume.
• Do clearance checks before you invest in branding so you reduce the risk of rebranding later due to infringement issues.
• Use your slogan consistently and keep evidence (screenshots, ads, packaging, dates) in case you need to prove reputation or confusion.
• Lock down ownership with the right contracts so employees, contractors, and agencies can’t re-use or disclose your brand assets.
• If a competitor copies your slogan, take a calm and strategic approach: gather evidence, assess your rights, and consider a lawyer-drafted letter to resolve it quickly.
