Working with overseas suppliers can be a huge win for your business. It can open the door to better pricing, faster scaling, more product options, and access to specialist manufacturing that might not be available in New Zealand.
But it can also be the moment where things get complicated fast - different laws, different time zones, different expectations, and a lot more risk if something goes wrong.
This (2026 updated) guide is designed to help you think through the key legal and practical issues before you commit to an overseas supplier, so you can set your business up with strong legal foundations from day one.
1. Have You Checked Who You’re Actually Dealing With?
One of the biggest risks with overseas suppliers isn’t even the product - it’s the identity of the supplier.
In cross-border deals, it’s easier for businesses to look legitimate online while being difficult to verify in reality. Even genuine suppliers may be operating through multiple entities (parent company, factory operator, export agent), which can create confusion about who is responsible for what.
Practical Supplier Due Diligence Checks
Before you pay a deposit or sign anything, it’s worth doing a basic “supplier due diligence” checklist. Depending on the supplier and the size of the deal, this might include:
- Confirming the legal entity name (not just the trading name on a website).
- Confirming the address and business registration details in the supplier’s country.
- Checking whether you’re dealing with a manufacturer or an intermediary (both can be fine, but you want clarity).
- Requesting references from other businesses (ideally in NZ or Australia, if available).
- Verifying bank account details match the contracting entity (mismatches can be a red flag).
From a legal perspective, the goal is simple: if you ever need to enforce your agreement, you need to know exactly who the agreement is with.
If you’re not sure how to structure the paperwork, it can be worth getting a contract lawyer to review the supplier’s documents or draft a clean agreement from scratch (templates often won’t cover the risks that come with international supply arrangements).
2. Is There A Written Contract That Covers The Real Risks?
If there’s one “non-negotiable” when working with overseas suppliers, it’s having a clear written contract.
Many suppliers will send a pro-forma invoice, a purchase order, or standard terms that are heavily supplier-friendly. Sometimes there’s no formal contract at all - just emails and a payment request.
The risk is that when something goes wrong, you’ll be relying on informal communications and assumptions. That’s a tough position to be in, especially across borders.
Key Terms To Include In An Overseas Supply Contract
Every business and product is different, but most overseas supplier contracts should clearly address:
- Product specifications (materials, dimensions, ingredients, tolerances, packaging requirements).
- Quality assurance process (sample approvals, testing standards, inspection rights).
- Minimum order quantities (MOQs) and what happens if you need to reorder or adjust volumes.
- Price, currency, and payment terms (including deposit amounts and milestone payments).
- Delivery terms (timelines, shipping method, and responsibility for delays).
- Warranties and remedies (replacement stock, refunds, credits, repair obligations).
- Liability allocation (who is responsible if the products cause loss or injury).
- Termination rights (when you can exit and what happens to work-in-progress stock).
- Dispute resolution (jurisdiction, governing law, and how disputes will be handled).
In practice, many New Zealand businesses combine a master supply agreement with purchase orders that sit underneath it. If your supplier relationship is ongoing, this structure can be much easier to manage than negotiating from scratch each time.
If you’re supplying goods to customers (especially consumers), the supplier contract becomes even more important, because you may be the one who has to handle refunds, replacements, and product issues in NZ - even if the supplier caused the problem.
3. What Laws Apply In New Zealand (Even If Your Supplier Is Overseas)?
A common misconception is: “If the supplier is overseas, it’s their problem.”
In reality, if you’re selling in New Zealand, you’re usually the one responsible for complying with New Zealand laws - regardless of where you sourced the goods.
Consumer Law: Advertising, Quality, And Refunds
If you sell to consumers, the Consumer Guarantees Act 1993 and Fair Trading Act 1986 are key. In plain terms:
- The goods you sell generally need to be of acceptable quality and match their description.
- You need to be careful about product claims (including marketing claims, “before and after” comparisons, and “made in” or sustainability claims).
- Misleading or deceptive conduct (even unintentionally) can expose your business to complaints and enforcement action.
This is why it’s important that your supplier contract gives you strong rights if products are defective or don’t match specifications - because you may have to fix the problem for your customers first, then try to recover your losses from the supplier later.
If you’re building out your storefront and customer terms at the same time, having strong eCommerce Terms and Conditions helps set expectations around delivery, returns, and how you handle customer issues (while still staying compliant with NZ consumer law).
Product Safety And Liability
Depending on what you import, you may also need to consider product safety obligations and product liability risk. If something causes harm - for example, an electrical fault, a cosmetic reaction, or a structural failure - the consequences can be serious.
That’s why it’s smart to build in:
- testing and certification requirements (where relevant),
- clear traceability (batch numbers, manufacturing dates), and
- indemnities and insurance expectations in your supplier contract.
For many businesses, your supplier is only one part of the risk picture - your customer-facing documents and processes matter too, including warranties and complaints handling.
4. Are You Protecting Your IP And Branding Before You Share Designs?
If you’re sending designs, formulas, prototypes, packaging artwork, or brand assets to an overseas supplier, you’re sharing valuable intellectual property (IP).
Even if you “own” the idea in a general sense, enforcing rights can be difficult if you haven’t put protections in place early.
Start With Confidentiality (But Make It Practical)
Before you share anything sensitive, a confidentiality agreement can help set clear expectations about:
- what information is confidential,
- what the supplier can use it for (and what they can’t),
- who they can disclose it to (for example, subcontractors), and
- what happens if confidentiality is breached.
A simple Non-Disclosure Agreement can be a good starting point, but it should align with your supply contract and the realities of manufacturing (for example, allowing disclosure to the factory floor while still restricting reuse).
Trade Marks Matter More Than Most People Think
If you’re building a brand in NZ, protecting your trade mark early is often one of the most cost-effective legal steps you can take - especially if your products are made overseas and you’re relying on consistent branding across packaging, product labels, and digital marketing.
Trade marks also help you enforce your brand on marketplaces and social platforms when copycats pop up.
If you’re not sure where to start, a Trade Mark Search Report can help you assess whether your brand is available before you invest heavily in packaging and stock.
Make Sure Your Contract Covers IP Ownership
Your supplier agreement should clearly say:
- you own your designs, artwork, branding, and product concepts,
- the supplier can’t reproduce or sell your product to others (including under a slightly modified version), and
- any improvements or variations created during production are dealt with properly (this is a common grey area).
This is particularly important if you’re paying for custom moulds, tooling, or product development work.
5. Have You Locked Down Quality Control, Samples, And Inspection Rights?
“Quality” can mean very different things in different markets. Even if your supplier is acting in good faith, misunderstandings about standards and tolerances are common.
If you’re planning to build a strong brand in NZ, quality control needs to be built into the relationship - not treated as an afterthought.
What Good Quality Control Clauses Look Like
Your agreement should clearly cover:
- Pre-production samples and whether they must be approved in writing.
- Production samples (for example, “golden sample” to match for the full run).
- Inspection rights (including whether you can appoint a third-party inspector).
- Acceptance/rejection criteria (what counts as a defect, and what defect rate triggers a remedy).
- Remedies (replacement, refund, credit, or rework at the supplier’s cost).
It’s also worth thinking about how you’ll document issues. If you ever need to dispute defective goods, evidence matters (photos, inspection reports, batch numbers, and clear timelines).
If you’re importing goods for resale, you should also be mindful of how returns and refunds will be handled at the customer level. Your internal processes and external terms should line up, so you’re not promising customers one thing while your supplier agreement leaves you with no practical remedy.
6. Are You Clear On Shipping Terms, Risk Transfer, And Insurance?
Shipping is one of the most misunderstood parts of overseas supply - and it’s where costs and delays tend to stack up.
You’ll want to be very clear about:
- who books freight,
- who pays for freight, customs, duties, and local delivery,
- when risk transfers (for example, when goods leave the factory vs when they arrive in NZ), and
- what happens if stock is damaged or lost in transit.
Use Clear Delivery Terms (And Don’t Assume)
Many supplier relationships use Incoterms (like EXW, FOB, CIF, DDP). These terms can be helpful shorthand, but only if both sides understand what they mean and you’ve matched them to your real-world freight arrangement.
Even small misunderstandings - for example, who is responsible for customs clearance, or whether insurance is included - can create large unexpected costs.
Insurance Should Match The Risk
Depending on your products and volumes, you might need to look at:
- marine cargo insurance (for goods in transit),
- product liability insurance (for goods sold in NZ), and
- recall insurance in higher-risk industries.
Your supplier contract should also say what insurance the supplier must hold (if any) and what evidence they must provide.
7. Can You Enforce The Deal If Something Goes Wrong?
This is the part many businesses only think about after the first major problem.
With overseas suppliers, enforcement can be challenging because:
- the supplier is in a different legal system,
- documents might be governed by foreign law,
- court proceedings overseas can be expensive and slow, and
- even if you “win”, collecting payment can be a separate challenge.
That doesn’t mean you shouldn’t work with overseas suppliers - it just means you should structure your deal with enforcement in mind.
Governing Law And Jurisdiction Clauses
Your contract should clearly set out:
- governing law (which country’s law applies), and
- jurisdiction (where disputes will be heard).
In some cases, it may be realistic to use NZ law and NZ courts. In other cases, the supplier will insist on their local law. Sometimes a more practical solution is international arbitration or a tiered dispute resolution clause (negotiation, mediation, then arbitration).
What’s “best” depends on your supplier, bargaining power, deal value, and what assets the supplier has. This is one of those areas where tailored legal advice can save you a lot of stress later.
Make Payment Terms Work For You
Enforcement isn’t only about courts - it’s also about leverage.
Smart payment structuring can reduce your risk, such as:
- smaller deposits, with more paid after inspection,
- holding a portion back until goods arrive and pass quality checks,
- using secure payment methods where appropriate, and
- having clear documentation requirements before payments are released.
Even if your supplier relationship is strong, having protective payment mechanics is part of running your business professionally.
Key Takeaways
- Before you commit to an overseas supplier, confirm who you’re contracting with and document the relationship clearly, so you’re not relying on informal emails if a dispute arises.
- A written supply contract should cover specifications, quality control, delivery terms, payment terms, warranties, liability allocation, and practical remedies for defective goods.
- If you sell in New Zealand, you still need to comply with laws like the Fair Trading Act 1986 and Consumer Guarantees Act 1993, even if the products were manufactured overseas.
- Protecting your intellectual property early (including confidentiality and trade marks) helps reduce the risk of copycats and misuse of your designs or branding.
- Quality control needs to be built into the relationship through samples, inspection rights, and clear acceptance criteria, so you can protect your brand reputation in NZ.
- Shipping terms, risk transfer, and insurance should be clearly agreed upfront to avoid unexpected costs and disputes about damage or delays.
- Enforcement is harder across borders, so it’s important to choose sensible governing law and dispute resolution options and structure payment terms to reduce risk.
