Tom Weston QC has practiced for 35 years as a commercial litigator throughout New Zealand.  He has appeared at all levels before the New Zealand Courts and regularly appears as counsel in arbitrations.  While his specialist area of interest is competition law and regulation, he primarily sees himself as a barrister specialising in the running of lengthy commercial trials.  As a consequence, he has experience across a range of commercial subject-matters such as companies and securities law, the law of trusts, professional liability, insurance, and building disputes.

Mr Weston was rated by Chambers & Partners Global 2017 as one of the top seven QCs practising in New Zealand.

In addition to his advocacy work, Mr Weston also sits regularly as an arbitrator in domestic arbitrations both individually and as part of a panel.  He also acts as a mediator.

He has written extensively in his areas of interest including in the New Zealand Law Journal.  He was an author of Sims High Court Practice for fifteen years.  He has presented papers at many conferences (insurance, commercial regulation, competition law etc).

Recent and Notable Cases

Recent cases include work on behalf of the Administrators of Solid Energy and The Helicopter Line, as well as the Feltex litigation (now in the Supreme Court).  He acts for family interests within the Gough Family trust litigation which has included hearings in the Court of Appeal and the Supreme Court.  He acted for Kiwibank in a case concerning money laundering: E-Trans v Kiwibank [2016] 3 NZLR 241.

He has many arbitration retainers including for listed public companies and one on behalf of an international manufacturer of industrial equipment.

He is regularly appointed as amicus by the High Court to assist the Court to represent interests not otherwise formally represented before it (including in relation to two applications brought by the Earthquake Commission to define its legal obligations:  Re Earthquake Commission [2011] 3 NZLR 695 and EQC v ICNZ [2015] 2 NZLR 381).
