In this article we employ Fairclough's model of critical discourse ana
lysis to explore the roles that public relations practitioners play in
discursive struggles. We also draw on Moffitt's work on articulation
and overdetermination to analyze the discursive practices employed by
public relations practitioners in the research, redesign and training
phases of discourse transformation. At the societal level, discourse t
ransformations emerge out of the discursive struggles engaged in by co
mpeting institutions and groups over sociocultural practices. The inst
ances of discursive struggle over sociocultural practices which are an
alyzed in this article are drawn from the environmental, labor relatio
ns and education policy areas in New Zealand and Western Australia.
