Research on New Zealand English has suggested that pragmatic markers such as eh and you know are associated with informal speech, while I think has been found to be more frequent in formal registers (Stubbe (Te Reo, 42:39–53, 1999); Stubbe and Holmes (Language and Communication 15:63–88, 1995)). New Zealand workplaces are considered to be relatively informal, but does analysis of pragmatic markers in workplace data support this? In this chapter, the use of these pragmatic markers is explored in white-collar data from the Wellington Language in the Workplace corpus, with a particular focus on the ways speakers may utilise them to strategically index informality in order to achieve their interactional goals.
