Industrial democracy and worker participation have become important topics for international debate, with developments taking place in many countries. Despite its former reputation for advances in the social field, little has been heard about developments in worker participation in New Zealand. The aim of the present paper is to report and assess such developments whilst placing these within the context of developments in industrial relations in that country. The strong reliance upon legal arrangements and government intervention in industrial relations matters have had a marked effect upon the development of the industrial relations system in New Zealand. Yet, despite this tradition of legalism, successive governments remain singularly reluctant to legislate in the field of worker participation. Recent initiatives by employers have been strongly unitary in nature, whilst the trade unions appear to be concentrating their efforts upon extending the scope of collective bargaining, an opportunity afforded to them due to recent changes in the law. The present Government's wish that voluntary arrangements between employers and trade unions will eventuate to cover worker participation seems less than pragmatic, since employers, unions and the Government itself differ so fundamentally upon what constitutes worker participation, and the forms it might take.
