About

Provided by Chapman Tripp

Chapman Tripp is a market leader in New Zealand competition, regulatory and antitrust law, advising on merger approvals, abuse of market power, cartel activity such as price fixing, anti-competitive arrangements, resale price maintenance, compliance audits and training programmes.

We have a sought-after team of competition law specialists, led by partners Neil Anderson and Matt Sumpter – two of New Zealand’s most experienced competition lawyers. This team advises an enviable client base comprising a mix of New Zealand’s largest corporates, key government and financial institutions, major primary sector operatives, core infrastructure providers and multinationals, including Z Energy, Vector Limited and Godfrey Hirst.

We have acted on multiple international cartel investigations and on the New Zealand competition aspects of global M&A deals through referrals from major international firms such as King & Wood Mallesons, Herbert Smith Freehills, Freshfields Bruckhaus Deringer and Skadden, Arps, Slate, Meagher & Flom. This work often involves complex parallel merger clearance applications in multiple jurisdictions.

We have advised on New Zealand’s most high profile contentious matters including Commerce Commission investigations and precedent-setting competition law litigation. We continue to develop our experience to our clients’ advantage by securing clearance for deals from competition authorities and winning landmark competition cases.
