This paper presents the result of an acoustic analysis of the more monophthongal of the New Zealand English vowels read in word lists for the Wellington Social Dialect Survey (carried out in 1989). Speakers are cross-classified by sex, social class, ethnicity and age, and a total of 75 speakers were recorded. In addition, comparisons are made with other (earlier and later) acoustic analyses of New Zealand English vowels, with a view to discovering diachronic trends or regional differences. Comparative figures for RP and Australian English are also given from a number of sources.
