This thesis investigates the status of te reo ā-iwi o Ngāti Hauā in the current climate of reo revitalisation among iwi Māori today. The key focus of this study conveys the views of Ngāti Hauā iwi within the context of reo Māori revitalisation, in particular, that of our own reo ā-iwi. As an extension to this approach the research explored the language of three Ngāti Hauā kaumātua from different generations and compared their language usage and language registers in the context of the particular roles they held within iwi at the time.
