This study presents a kinematic and acoustic comparison of the vowels spaces of New Zealand English (NZE) and Australian English (AE). Five talkers of NZE (3F and 2M) and five female talkers of AE each produced between 9 - 15 tokens of the monophthongs in HEAD, HID,HAD, and HERD. For each token, measurements of lip aperture, lip protrusion, jaw height, and tongue height and backness were made, in addition to formants and vowel duration being calculated. There were three main findgs from this study. Firstly the widely held view that the NZE HID vowel may have lowered as it centralised may be incorrect. In this study results suggest that although the NZE HID vowel is retracted it remains a high front vowel. The second results is HERD is lip rounded in NZE and AE. The final finding is that there is no significant difference in vowel duration between NZE and AE HEAD and HAD, despite NZE HEAD and HAD being phonetically more raised. The implications of these results are discussed.
