Commerce Commission’s Digital Markets Act targeting tech giants faces implementation hurdles

The Commerce Commission’s enforcement of New Zealand’s Digital Markets Act is encountering significant implementation challenges as major tech platforms resist compliance measures. Early regulatory actions suggest a complex path ahead for governing digital competition in New Zealand’s small but strategically important market.

• Commerce Commission issued first formal warnings to three major tech platforms in March 2026
• Compliance costs for designated digital gatekeepers estimated at $15-25 million annually
• International coordination discussions underway with Australian and UK regulators
• Small business advocacy groups report mixed early outcomes from new interoperability requirements
• Legal challenges expected from at least two major platforms by mid-2026

The Commerce Commission’s initial enforcement actions under the Digital Markets Act have revealed the practical complexities of regulating global tech giants within New Zealand’s jurisdiction. Three major platforms received formal warnings in March for failing to meet interoperability requirements, marking the first significant test of the legislation passed in late 2025.

“We’re seeing a pattern of minimal compliance strategies designed to meet the letter of the law while avoiding its spirit,” says Commerce Commission Chair Anna Rawlings. The regulatory challenges mirror those experienced in the European Union’s implementation of similar digital market rules, but New Zealand’s smaller market size creates unique enforcement dynamics.

Compliance costs mounting rapidly

Designated digital gatekeepers face estimated annual compliance costs of $15-25 million each, according to regulatory impact assessments. These figures represent a significant burden relative to New Zealand-specific revenues for some platforms, potentially creating incentives for market exit strategies rather than full compliance.

Legal firms specialising in competition law report unprecedented demand for advisory services. “The Act’s extraterritorial reach combined with its broad definitional scope creates compliance uncertainty that’s driving extensive legal consultation,” notes Chapman Tripp partner Michael Wigley.

According to New Zealand Law Society, the regulatory framework presents significant jurisdictional challenges that may require legislative refinement within the first year of operation.

Small business representatives express cautious optimism about improved platform access but worry about unintended consequences. “We’re seeing some positive changes in app store policies, but also new barriers emerging as platforms restructure their compliance approaches,” says Canterbury Employers’ Chamber of Commerce CEO Leeann Watson.

International coordination essential

The Commission is actively coordinating with Australian and UK counterparts to ensure consistent enforcement approaches. This collaboration becomes critical when platforms adopt different compliance strategies across jurisdictions, potentially creating market fragmentation.

Regulatory experts predict at least two major legal challenges will emerge by mid-2026, likely focusing on the Act’s market definition criteria and penalty structures. The outcomes of these challenges will significantly influence the long-term effectiveness of New Zealand’s digital markets regulation.

“Early implementation always reveals gaps between policy intent and practical enforcement,” observes Victoria University competition law expert Professor Lewis Evans. “The Commission’s learning curve will be steep, but their willingness to issue early warnings suggests a robust enforcement approach.”

Market analysts note that New Zealand’s regulatory approach could serve as a testing ground for more proportionate digital market governance, particularly for smaller economies seeking to balance innovation incentives with competition protection. The next six months will prove crucial for establishing the Act’s credibility and long-term viability.
