Book excerpt: This book provides practitioners and students with a full treatment of one of the most important and complex aspects of company law, directors' powers and duties. Of all the areas of company law, directors' powers and duties is among the least accessible from the statute (i.e. Companies Act 1993). Behind the statute, is a long and very complex history of equitable and common law case law, most of which remains applicable in New Zealand. This book also contains short summaries of leading cases which is very useful both for students and practitioners.
