About

Provided by Simpson Grierson

Our team of experts advises on all aspects of competition law and are recognised market leaders. By working closely with our clients to understand their business and the industries they operate in, we are able to produce practical advice that is tailored to their specific needs and desired outcomes.

We have a strong history of obtaining clearance from the Commerce Commission in relation to complex mergers and acquisitions and are frequently engaged by overseas law firms to act on global transactions.

We regularly act for clients in Commerce Commission investigations and court proceedings relating to alleged restrictive trade practices, such as price fixing and anti-competitive agreements. We also assist clients with applications for cartel leniency.

Our team frequently advises on non-contentious matters, such as general advisory work in relation to compliance with cartel laws, misuse of market power, access issues, joint ventures and other competitor collaborations. We also assist clients to implement compliance programmes.
