Affiliate Marketing Legal Essentials In New Zealand

Affiliate marketing can be a cost-effective way to grow your sales, build brand awareness, and tap into audiences you’d struggle to reach on your own.

But once you start paying commissions for clicks, leads, or sales, you’re also stepping into a space where consumer law, advertising rules, privacy obligations, and contract risk all matter.

If you’re running an online store, subscription service, SaaS, coaching business, or any other small business in New Zealand, this guide will walk you through the legal essentials of affiliate marketing so you can scale with confidence (and avoid nasty surprises later).

This article provides general information only and doesn’t constitute legal advice. If you need advice about your specific affiliate program, it’s worth getting tailored guidance.

What Is Affiliate Marketing (And Why Do The Legal Details Matter)?

Affiliate marketing is where you partner with third parties (affiliates) who promote your product or service and earn a commission when they drive a desired result, such as:

• a sale (e.g. a percentage of revenue);
• a lead (e.g. a fixed payment per enquiry or sign-up);
• a click (less common now, but still used in some industries).

In practice, you might have affiliates who are:

• content creators and publishers (blogs, review sites, newsletters);
• industry experts and consultants who refer clients;
• existing customers or community members;
• other businesses doing cross-promotions.

The legal risk is that affiliates can look and feel like an extension of your marketing team. Even if they’re independent, their advertising can still create problems for your business if it’s misleading, non-compliant, or mishandles customer data.

So the key question isn’t just “how do we launch an affiliate program?” It’s “how do we launch an affiliate program that protects the business from day one?”

What Laws Apply To Affiliate Marketing In New Zealand?

Affiliate marketing sits at the intersection of marketing, consumer protection, and data handling. That means a few core laws often come into play.

Fair Trading Act 1986 (Misleading Or Deceptive Conduct)

The Fair Trading Act 1986 is one of the biggest legal “watch-outs” for affiliate marketing. In plain terms, it means you can’t mislead customers (or let your marketing mislead customers) about what you’re selling.

This matters because affiliates often publish:

• “best of” lists and product comparisons;
• reviews and testimonials;
• discount or pricing claims;
• performance claims (e.g. “guaranteed results”).

If an affiliate makes claims that are misleading or can’t be substantiated, you could end up dealing with customer complaints, reputational damage, or (in serious cases) regulatory attention.

Practical tip: give affiliates a “claims guide” (what they can and can’t say) and keep a right to require edits or removal if content is non-compliant.

Consumer Guarantees Act 1993 (If You Sell To Consumers)

If you sell goods or services to consumers in NZ, the Consumer Guarantees Act 1993 will often apply. This affects things like acceptable quality, fitness for purpose, and remedies if something goes wrong.

Affiliate marketing can create legal trouble if affiliates oversell your product, misrepresent what’s included, or imply “no refunds” when consumer guarantees may still apply.

Practical tip: align your affiliate messaging with your actual customer terms, shipping policy, and refund processes. Marketing should never promise what your operations can’t deliver.

Privacy Act 2020 (Tracking, Referrals, And Customer Data)

Affiliate marketing commonly involves tracking links, cookies, pixels, and referral codes. That can involve “personal information” (for example, if you can identify an individual directly or indirectly).

Under the Privacy Act 2020, you generally need to:

• collect personal information for a lawful purpose and only what you need;
• tell people what you’re collecting and why (transparency);
• store it securely and only keep it as long as needed;
• ensure third parties handling data don’t misuse it.

This is where your website Privacy Policy becomes more than just a box-ticking exercise. It should match what your affiliate tracking actually does.

Practical tip: if you share data with affiliates (even something as simple as “this affiliate made a sale to Customer X”), consider whether you’re disclosing more than you need to and whether you’ve clearly explained this to customers.

Unsolicited Electronic Messages Act 2007 (Spam Rules)

If affiliates are emailing or texting promotions, spam rules can be triggered. While affiliates are independent, you don’t want your program associated with spammy practices.

Practical tip: your affiliate terms should clearly prohibit spam and require compliance with NZ marketing laws, and you should reserve the right to suspend or terminate affiliates who breach these rules.

Advertising Standards (ASA Codes And Disclosure Expectations)

In New Zealand, affiliate content is also commonly expected to follow the Advertising Standards Authority (ASA) Advertising Codes. These aren’t statutes, but they can still matter in practice because complaints can be made about ads that are misleading or not clearly identifiable as advertising.

This is especially relevant where affiliates are influencers, reviewers, or publishers and the content could be seen as “editorial” unless it’s clearly labelled.

Practical tip: require affiliates to clearly disclose the commercial relationship (for example, “ad”, “affiliate link”, “sponsored”, or an equivalent clear disclosure) and to keep disclosures prominent (not hidden in footers or behind “more” buttons).

How Do You Structure Affiliate Relationships Without Creating Problems?

Before you sign anyone up, you’ll want to think about what the relationship actually is in legal terms.

Most affiliate arrangements are structured as an independent contractor / referral relationship, not employment. That’s usually what you want, because employment comes with payroll obligations, leave entitlements, and a different risk profile.

That said, classification depends on how the relationship works in reality (not just what you call it). If you tightly control hours, processes, and performance like they’re staff, the relationship can start to look like employment.

If your affiliates are individuals doing regular work for you, it can be worth documenting the relationship properly with a tailored Contractor Agreement (or affiliate terms drafted with contractor-style protections).

Practical tip: keep affiliates genuinely independent. For example, you can set brand guidelines and compliance rules, but avoid directing their day-to-day work like they’re on your payroll.

What Should Your Affiliate Terms And Conditions Include?

Your affiliate program should never rely on “handshake deals” or vague DMs. If an affiliate relationship goes bad, you want the agreement to do the heavy lifting.

Some businesses use standalone affiliate terms and conditions (often hosted on their website), while others use a signed agreement for each affiliate. Either way, the legal goals are the same: clarity, control, and enforceability.

Here are clauses and topics commonly worth including.

1) Commission Structure And Payment Rules

Spell out exactly how commission is earned and calculated, including:

• what counts as a “valid” referral (sale/lead/click);
• what happens with refunds, chargebacks, or cancellations;
• cookie duration / attribution rules (who gets the credit);
• payment timing, thresholds, and payment method;
• tax responsibilities (e.g. whether the affiliate is responsible for their own tax, and whether any GST applies).

Note: tax and GST treatment can vary depending on how the affiliate operates (for example, whether they are GST-registered and where they’re based). Consider getting accounting advice on your specific setup.

This is where many disputes start-especially if an affiliate believes they “earned” commission but you later void it due to refund fraud or non-compliant traffic.

2) Marketing And Compliance Rules (What They Can And Can’t Do)

You should clearly set boundaries around how affiliates can promote you, including rules about:

• truthful advertising and substantiation of claims (Fair Trading Act);
• discounting and pricing (no fake “was/now” deals);
• testimonial and review rules (no fake reviews, no misleading endorsements);
• clear disclosure of affiliate relationships (including where ASA Advertising Codes apply);
• spam and unsolicited messages;
• prohibited content (e.g. offensive, unlawful, or brand-damaging content);
• use of your trade marks and brand assets.

If you have partners doing more formal promotions (like co-branded campaigns), a tailored Marketing Services Agreement can also help lock down approvals, deliverables, and who is responsible for what.

3) Intellectual Property And Brand Use

Affiliates often need to use your:

• logos and brand names;
• product images and videos;
• marketing copy;
• trade marks and taglines.

Your terms should confirm you own (or control) your IP, and affiliates get a limited licence to use it only for the affiliate program and only while they’re compliant.

You should also cover what happens to content they create. For example: do you want the right to repost affiliate-generated videos on your channels? If yes, get that permission clearly (and ideally, in writing).

4) Confidentiality And Data Handling

Affiliates may learn sensitive information such as:

• conversion rates, pricing strategy, or launch timelines;
• private discount codes;
• customer or lead information (if you share it).

Your terms should include confidentiality obligations and restrictions on using or disclosing information outside the program. Depending on your business, a separate Non-Disclosure Agreement can be useful for higher-value partners.

5) Fraud, Prohibited Traffic, And Chargeback Protection

Affiliate fraud is real, and you don’t want to pay commission for fake leads or manipulated sales. Your terms can cover:

• no self-referrals (or rules about when self-referrals are allowed);
• no fake accounts, fake leads, or incentive abuse;
• no adware, cookie stuffing, or misleading redirects;
• your right to withhold or claw back commission in specific cases.

Be specific about what you can do and when-because if you want to withhold payment, you’ll need contractual support.

6) Termination Rights (And What Happens After)

A good affiliate program gives you control. That means having clear termination rights, including:

• termination for breach (immediate);
• termination for convenience (with notice);
• what happens to outstanding commissions at termination;
• how quickly they must stop using brand assets and affiliate links.

If you don’t have this, you could end up stuck with a “partner” who’s hurting your brand-and limited ability to respond quickly.

7) Liability, Indemnities, And Risk Allocation

This is one of the most important (and most often overlooked) parts.

Your affiliate terms should deal with:

• limits on your liability to the affiliate;
• the affiliate’s responsibility for their own actions and content;
• indemnities if their conduct causes you loss (e.g. legal claims, regulator issues, platform bans).

These clauses can be the difference between an annoying dispute and a truly expensive one.

Do You Need A Privacy Policy, Cookie Policy, Or Website Terms For Affiliate Marketing?

If you’re running affiliate marketing, you’re usually operating online-and that means your website documents matter more than you might think.

Privacy Policy And Tracking Disclosures

Your Privacy Policy should accurately describe:

• what personal information you collect (including via analytics and tracking tools);
• why you collect it (including affiliate attribution and performance measurement);
• who you share it with (including platforms, service providers, and potentially affiliates);
• how users can request access or correction.

If you’re using cookies or similar tracking technology, you should also make sure your cookie and consent approach matches what’s actually happening on your site (especially if you deal with overseas customers or use global marketing tools).

Website Terms And Conditions

Affiliates can drive a lot of first-time buyers to your website. That means your customer-facing terms need to be tight, clear, and consistent with your marketing.

Depending on your business model, this might mean having:

• online shop terms (sales, returns, shipping);
• subscription terms (billing cycles, cancellation, renewal);
• acceptable use rules (if you’re a platform or SaaS product);
• disclaimers that match what you’re actually selling.

Many small businesses start with basic website terms, then refine them once marketing ramps up. But affiliate marketing can scale quickly-so it’s smart to have your Website Terms and Conditions in place early.

Common Affiliate Marketing Mistakes NZ Businesses Make (And How To Avoid Them)

You don’t need a “perfect” affiliate program on day one. But you do want to avoid the mistakes that cause the biggest legal and commercial headaches.

Mistake 1: Letting Affiliates Say Anything They Want

If you don’t set rules, affiliates will default to what gets clicks-big claims, exaggerated results, and comparisons that might not be accurate.

Fix: create clear marketing do’s and don’ts in your affiliate terms, and actively monitor high-performing content.

Mistake 2: Using Template Terms That Don’t Match Your Program

Affiliate programs vary a lot. A generic template might not cover your attribution rules, refund logic, prohibited traffic, or the reality of how you operate.

Fix: get your affiliate terms drafted (or at least reviewed) so they reflect what you’re actually doing and what risks you’re actually exposed to.

Mistake 3: Paying Commission Without A Clear Paper Trail

If you can’t show how commission was calculated, disputes become “your word vs their word”. That’s a time drain and can turn into reputational damage.

Fix: document calculation rules and keep reporting systems that can be exported and audited if needed.

Mistake 4: Not Thinking About Privacy Until There’s A Complaint

Affiliate tracking is often invisible to customers, which is exactly why transparency matters.

Fix: make sure your privacy disclosures match your tracking practices, and double-check what data is shared with third parties.

Mistake 5: Treating Affiliates Like Staff (Without Any Employment Paperwork)

If you start controlling affiliates like employees, you can accidentally create legal ambiguity (and practical conflict).

Fix: keep affiliates independent, and use the right agreement structure to reflect that reality.

Key Takeaways

• Affiliate marketing can be a powerful growth channel for NZ businesses, but it needs clear legal foundations to protect you as you scale.
• Your affiliate promotions should comply with the Fair Trading Act 1986, particularly around misleading claims, pricing statements, and testimonials.
• In practice, affiliate promotions should also be clearly identifiable as advertising where appropriate (including by following ASA Advertising Codes and using clear disclosures like “ad” or “affiliate link”).
• If you sell to consumers, the Consumer Guarantees Act 1993 can affect how your product should be described and what remedies customers may be entitled to.
• Affiliate tracking and referral systems can involve personal information, so your Privacy Policy and data handling practices should align with the Privacy Act 2020.
• Strong affiliate terms should cover commission rules, refund/chargeback handling, compliance obligations, brand use, confidentiality, fraud controls, termination rights, and liability allocation.
• It’s worth getting the agreements and website terms set up properly from day one-templates often miss the exact risks affiliate programs create.
