New Zealand Competition Law: Staying Compliant and Avoiding Anti-competitive Conduct

Competition law can catch growing businesses earlier than most founders expect. The risk is not limited to big corporates or headline cartel cases. A small supplier discussing prices with a competitor, a franchisor setting hard resale prices, or a business signing an exclusive deal without thinking through market impact can all create real problems under New Zealand law.

The most common mistakes are surprisingly ordinary. Businesses copy a competitor's pricing conversation into a group chat, include restrictions in contracts that go further than necessary, or assume market-sharing arrangements are acceptable because everyone in the industry does them. This guide explains what New Zealand competition law actually covers, when issues usually arise, and what practical steps can help your business stay compliant before you sign a contract, launch a pricing strategy, or negotiate with a distributor.

Overview

New Zealand competition law is mainly designed to stop businesses from limiting competition in ways that harm markets, suppliers, and customers. For most SMEs, the key legislation is the Commerce Act 1986, supported by other rules that affect how businesses market, contract, and deal with customers.

The main compliance question is usually whether your business is competing fairly on its own merits, or whether it is coordinating, restricting, or using market power in a way the law may prohibit.

• Check whether you are discussing prices, customers, territories, bids, output, or strategic plans with competitors.
• Review contracts for exclusivity, minimum resale pricing, bundling, or restrictions that may substantially lessen competition.
• Consider whether your business has significant market power and whether a proposed strategy could amount to misuse of that power.
• Train staff who handle sales, procurement, industry meetings, and distribution arrangements.
• Keep marketing, pricing, privacy, and contract practices aligned, especially if you are selling online or expanding quickly.

What Competition Law Means For New Zealand Businesses

Competition law means your business must make independent commercial decisions and avoid arrangements or conduct that improperly restrict competition in New Zealand markets.

In practice, this usually comes back to a few core rules under the Commerce Act 1986. The law is concerned with conduct that prevents markets from working properly, such as competitors coordinating instead of competing, or a business with substantial market power using that position in a way that damages competition.

The main areas businesses should know

Most founders do not need to memorise legislation, but they do need to recognise the patterns that create risk. The main areas are:

• Cartel conduct, including price fixing, restricting output, market allocation, and bid rigging.
• Arrangements that have the purpose, effect, or likely effect of substantially lessening competition.
• Misuse of substantial market power.
• Resale price maintenance, where a supplier tries to control the minimum price at which resellers sell goods.
• Mergers or acquisitions that may substantially lessen competition, which may require specialist advice before completion.

Cartel conduct is not just a big business issue

Cartel conduct often sounds like a problem for large industries, but SMEs can be exposed too. If two competing businesses agree to keep prices above a certain level, avoid targeting each other's customers, split territories, or coordinate tender responses, that can raise serious concerns.

The risky part is that the agreement does not always need to be formal. A handshake, text exchange, coffee meeting, WhatsApp chat, or repeated informal understanding may still be enough to create legal exposure.

Substantially lessening competition

Many business arrangements are legal, even if they restrict conduct in some way. The question is often whether the arrangement goes so far that it substantially lessens competition in a market.

That assessment depends on context, such as market share, barriers to entry, the number of competitors, the duration of the restraint, and whether customers still have real alternatives. A distribution restriction that is manageable in a crowded market may be much riskier in a niche industry with only a few players.

Misuse of market power

A business with substantial market power is allowed to compete hard. What it cannot do is use that power for conduct that has the purpose, effect, or likely effect of substantially lessening competition.

This issue sometimes arises with dominant suppliers, digital platforms, or businesses that control access to key channels. Heavy discounting, exclusivity, refusals to supply, loyalty rebates, and bundling are not automatically unlawful, but they can become risky when they block competitors rather than simply win customers fairly.

How this connects with other legal areas

Competition law does not sit in isolation. The same commercial behaviour often touches other legal obligations too.

• Contracts matter because many competition risks appear in supply agreements, distribution deals, franchise arrangements, software terms, and procurement contracts.
• Fair Trading Act obligations matter because pricing claims, promotions, and comparative advertising still need to be accurate and not misleading.
• Privacy issues can arise if you collect competitor or customer data inappropriately or share commercially sensitive information carelessly.
• Trade mark and branding issues can matter where businesses coordinate on packaging, product presentation, or channel strategies.
• Business structure matters because parent companies, subsidiaries, joint ventures, and agent relationships can affect how arrangements are analysed.

For startups, this usually means competition compliance should be built into commercial decision-making early, especially before you scale distribution, appoint exclusive partners, or enter a market dominated by a few incumbents.

When This Issue Comes Up

Competition law issues usually appear at ordinary commercial decision points, not only during major disputes or investigations.

Founders often first encounter the issue when a deal sounds commercially sensible but involves coordination or restrictions that may affect the wider market. Here are some of the most common moments where businesses should pause and assess risk.

When talking with competitors

Conversations with competitors are one of the biggest danger areas. Industry association meetings, conference chats, collaborative projects, and supplier roundtables can all drift into sensitive topics very quickly.

Problems often start when people discuss:

• future pricing or discounts
• customer allocation
• territories or regions
• production levels or capacity
• which tenders to pursue or avoid
• plans to enter or leave a market

Even if no deal is reached, sharing strategic information can still create risk. Staff should know when to stop a conversation and record that they did not participate.

When drafting supply or distribution contracts

Many competition issues are embedded in contracts. A clause can look commercially standard and still need closer review.

This often comes up before you sign a contract that includes:

• exclusive supply or exclusive dealing obligations
• territorial restrictions
• online sales restrictions
• bundling requirements
• long lock-in periods
• minimum resale pricing controls

Some of these terms may be lawful in the right context. The main risk is using them more broadly than necessary or in a market where they significantly shut out competitors.

When responding to tenders or procurement opportunities

Tendering creates a high-risk environment for anti-competitive conduct. Businesses sometimes try to avoid undercutting each other or share information about bid levels because the market is small or relationships are long-standing.

That is exactly where founders often get caught. Agreements about who will win a tender, who will submit a cover bid, or who will stay out of the process can amount to bid rigging.

When appointing resellers, franchisees, or marketplace sellers

Growth businesses often want consistency across channels. That is commercially understandable, but hard rules on resale pricing can be unlawful.

You can usually recommend resale prices or set a maximum price in some contexts, but trying to force a reseller not to go below a minimum price is where resale price maintenance concerns can arise. This should be reviewed carefully before you print reseller terms, launch a wholesale programme, or sign channel partner agreements.

When scaling fast or entering a concentrated market

Fast growth changes the legal analysis. A practice that seems harmless when your business is small can become riskier once you hold stronger market power or become an important gateway for customers.

This is especially relevant if you are going through company setup in New Zealand in a niche sector, build a platform business, or become one of only a few suppliers. Before you spend money on setup, exclusivity, or aggressive pricing campaigns, it is worth checking whether the strategy is simply competitive or may be seen as excluding rivals.

When buying another business or assets

Competition law often becomes a live issue during acquisitions, mergers, and some joint ventures. The concern is whether combining businesses will substantially lessen competition.

Even smaller deals can raise questions in local or specialised markets. Businesses should get advice early, before transaction documents are finalised and before announcing completion steps to customers or suppliers.

Practical Steps And Common Mistakes

The safest approach is to build competition law checks into pricing, contracting, sales, procurement, and strategic planning before risky conduct becomes normal business practice.

Most businesses do not need a complex compliance system. They need clear rules, sensible contract review, and staff who know where the danger points are.

1. Make independent decisions on price and strategy

Your pricing, discounting, customer targeting, and output decisions should be made independently. Do not align these decisions with competitors, even informally.

If your team attends industry meetings or deals with competitors in some capacity, set a rule that they must not discuss commercially sensitive matters. Keep a written note if a conversation becomes inappropriate and your representative leaves or objects.

2. Review contracts for competition risk before you sign

Competition issues often sit quietly inside ordinary commercial documents. A legal review should look not only at whether the drafting is enforceable, but also at whether the restrictions go further than needed.

Clauses worth reviewing closely include:

• exclusivity terms
• restraints on customers or territories
• non-compete obligations in commercial arrangements
• minimum purchase commitments tied to market access
• pricing controls imposed on distributors or resellers
• most favoured customer clauses

Founders sometimes assume a term is safe because a supplier template includes it. That is not a reliable test.

3. Be careful with trade associations and collaborative projects

Industry groups can be useful, but they need boundaries. Collaboration should be structured around legitimate objectives and not become a channel for coordination.

If your business is joining an association, participating in a benchmarking exercise, or discussing a joint initiative, think about:

• what information will be shared
• whether the information is current or future-facing
• whether it identifies individual businesses
• whether the project could influence competitive behaviour
• whether minutes and agendas clearly limit discussion topics

Joint ventures and collaborations can be legitimate, but they need careful design. The exception for collaborative activity can be technical, so this is an area where tailored advice is often worthwhile.

4. Train the people who create the highest risk

Competition compliance should not stop with founders. Sales staff, procurement managers, business development leads, franchise managers, and anyone attending industry events should understand the basics.

A short internal policy can help cover:

• which topics must never be discussed with competitors
• how to handle an unexpected pricing conversation
• when legal sign-off is required for distribution or exclusivity terms
• how to respond to tenders independently
• who to contact internally if a concern arises

The mistake here is waiting until the business is much larger. Early training is often easier and cheaper than repairing a bad practice that has become routine.

5. Watch resale pricing and channel controls

Many product businesses want brand consistency, especially when selling online through multiple outlets. That goal needs to be handled carefully.

You can often protect brand presentation through lawful channel standards, marketing rules, and quality controls. The risk increases when those controls cross into setting a minimum resale price or pressuring resellers not to discount.

Before you launch online, appoint stockists, or build a franchise-style network, review the commercial model as a whole. What matters is not just what the contract says, but also what sales staff say in practice.

6. Consider the full legal picture, not just competition law

Businesses often treat pricing or distribution as a standalone commercial issue. In reality, the same project may involve several legal workstreams.

For example, if you are selling online through exclusive channels, you may need to think about:

• contract terms with suppliers, distributors, and marketplaces
• privacy policy updates and disclosures if you collect customer data
• Fair Trading Act compliance for pricing claims and promotions
• trade mark protection for your brand and product names
• business structure and registration if you are expanding into a new entity or joint venture

This does not mean every expansion plan is high risk. It means legal review works best when it is done early and in context.

Common mistakes SMEs make

The most common mistakes are practical rather than technical.

• Assuming informal conversations are harmless because nothing was signed.
• Using standard overseas templates without checking New Zealand law.
• Forcing reseller pricing instead of recommending it.
• Accepting broad exclusivity terms without considering market impact.
• Letting sales teams speak too freely with competitors at events.
• Leaving merger or acquisition advice until the documents are nearly final.

If any of these sound familiar, the right response is usually to pause, document the current position, and get the arrangement reviewed before it expands further.

FAQs

Does competition law only apply to large companies?

No. Small businesses, startups, franchises, local suppliers, and online sellers can all be affected. The law focuses on the conduct and its market impact, not just the size of the business.

Can I talk to a competitor about pricing if it is only general market chat?

You should be very careful. Discussions about current or future pricing, discounts, margins, customer allocation, or tender intentions can create risk quickly, even if the conversation is informal and no written agreement follows.

Is exclusivity always illegal under New Zealand competition law?

No. Exclusive dealing is not automatically unlawful. The key question is whether the arrangement has the purpose, effect, or likely effect of substantially lessening competition in the relevant market.

Can I tell resellers the minimum price they must charge?

That can raise resale price maintenance concerns. Businesses should be cautious about imposing minimum resale prices or pressuring resellers not to discount, even where brand consistency is important.

When should I get legal advice?

Get advice before you sign a contract with exclusivity or resale controls, before you collaborate with competitors, before you respond to a sensitive tender situation, or before you complete a merger, acquisition, or joint venture in a concentrated market.
