International trade and investment

International trade and investment

Helping businesses and governments navigate the rules, risks and opportunities of doing business across borders.

International business increasingly sits at the intersection of trade regulation, national security, geopolitics and rapidly changing technology. We help businesses, financial institutions and governments navigate these rules, manage cross-border risk and pursue international opportunities.

Our specialist international trade team advises on all aspects of cross-border business, from entering new markets and planning supply chains to customs, sanctions and export-control compliance, regulatory investigations and disputes. We combine technical expertise with practical commercial advice and strategic government engagement.

How we can help
  • Sanctions and export controls: Strategic goods and dual-use classifications, defence trade controls, export licensing, sanctions exemptions, end-user due diligence, screening, technology transfers, compliance programmes, voluntary disclosures and enforcement.
  • Customs, tariffs and trade remedies: Tariff classification, customs valuation, origin, import and export requirements, US and other tariff measures, customs disputes, anti-dumping, countervailing duty and safeguard investigations.
  • Market access and product regulation: Help navigating the rules for bringing products, technologies and services to market, including licences, approvals, product standards, labelling and ongoing compliance.
  • Strategic and responsible supply chains: Geopolitical and supply-chain risk, contractual protections, forced-labour and modern slavery risk, ethical sourcing and emerging responsible-trade requirements.
  • Trade agreements, investment and government engagement: Free trade agreements, WTO rules, market-access and investment barriers, treaty interpretation, trade policy, regulatory reform and government engagement.
  • Investigations and disputes: Internal investigations, voluntary disclosures, regulatory and Police investigations and enforcement, judicial review and litigation.
A specialist practice for complex cross-border matters

We advise on day-to-day compliance through to strategically significant transactions, market-entry projects, investigations and disputes. Our experience includes advising financial institutions, global technology businesses, exporters and manufacturers, aerospace and defence businesses, logistics providers, industry bodies and New Zealand and overseas government agencies.

We have particular experience where international trade regulation intersects with technology and national security, including aerospace and autonomous systems, defence-related technologies, telecommunications and satellites, advanced manufacturing, software and cryptography. Where matters span jurisdictions, we coordinate with overseas counsel and international law firms.
