Political Staff in Executive Government: Conceptualising and Mapping Roles within the Core Executive

Political advisers are attracting increasing attention in Westminster jurisdictions. Typically, scholars focus on the corrosive impact they allegedly have on elements of Westminster convention and practice. We argue that a concern with accountability detracts from other important matters, including understanding and theorising ministerial advisers' roles. In this article we address these issues using primary data from a survey of ministerial advisers in New Zealand. We draw on Maley's typology to classify advisers' activities according to the contribution they make to executive government policy-making. We then theorise these activities through the lens of the core executive. We conclude that ministerial advisers are increasingly important actors in governing environments characterised by complex resource dependencies, modes of operation that are as often relational as they are hierarchical, and bargaining relationships that are often positive and not zero-sum in nature.
