Campbell specialises in international law and dispute resolution. After taking his LLB at Victoria, Campbell studied in Europe and then practised law as a partner in the firm of Herbert Smith, and as Head of its International Law Practice Group, until his return to New Zealand in 2003. Campbell is President of the Australian and New Zealand Society of International Law, an Arbitrator for the International Centre for the Settlement of Investment Disputes, and a Member of the International Chamber of Commerce Court of Arbitration.

He is a Specialist Editor for the 14th edition of Dicey, Morris and Collins on the Conflict of Laws (2006), the leading text on Private International Law in the Common Law world, and is responsible in particular for the chapter on Arbitration. His book (with Shore and Weiniger) International Investment Arbitration: Substantive Principles was published by OUP in 2007, and is the first modern study of the law applicable in investment treaty arbitration. It won the J F Northey Prize in 2008.

In July 2008, he became the first New Zealand-based academic to give a course of lectures at The Hague Academy of International Law. His topic was ‘Lis Pendens in International Litigation.’ The lectures will be published in 2009. Campbell was appointed Queen’s Counsel in 2007.
