Competition and Consumer Law

Many New Zealand markets are highly concentrated. Entry can be challenging where there appears to be room for only 2 or 3 major players. Additionally, the Commerce Commission is a well-resourced and vigilant regulator aiming to protect the welfare of consumers.

We provide considerable expertise in all aspects of Commerce Commission work, including defending investigations and prosecutions, applying for clearance or authorisation, and administrative law or judicial review cases. We offer clients a unique perspective blending litigation and commercial skills, having worked in both dispute resolution and transactional merger clearance.

Competition and trade practices law covers all manner of dealings with the Commission or courts on matters of cartels or collusion, misuse of market power, anti-competitive contracts and business practices, merger clearance control, and JV collaboration. Consumer law includes Fair Trading Act and unfair contract terms expertise along with consumer finance/credit. We also offer experience in price control and sector-specific regulation in utilities and energy.
