This article examines the phenomenon of increased political pressures on governments in four Westminster systems (Australia, Britain, Canada, and New Zealand) derived from changes in mass media and communications, increased transparency, expanded audit, increased competition in the political marketplace, and political polarization in the electorate. These pressures raise the risk to impartial public administration and management performance to the extent that governments integrate governance and campaigning, allow political staff to be a separate force in governance, politicize top public service posts, and expect public servants to be promiscuously partisan. The article concludes that New Zealand is best positioned to cope with these risks, in part because of its process for independently staffing its top public service posts. The article recommends this approach as well as the establishment of independently appointed management boards for public service departments and agencies to perform the governance of management function.
