The intent of this thesis is to investigate the role media plays in relation to the revitalisation of te reo Māori in Aotearoa/New Zealand society. This is essential as the media's latent potential is often underestimated and therefore underutilised. For Māori and inevitably te reo Māori, media has been a topic of heated contestation for over a century. It is postulated that throughout this troubled history, media's influence has contributed to an erosion of te reo Māori and then conversely, since the late 20th century, its attempted revival. The journey of te reo Māori from past to present may be likened to a voyage of a traditional 'waka hourua' (voyaging or double hulled canoe). 'Nga ngaru e toru' ('three waves') illustrates the three stages that I have defined as catalysts significantly impacting te reo Māori. Grounded firmly in a Kaupapa Māori methodological and theoretical framework based on careful research and intimate cultural knowledge, my innovative approaches to language revitalisation entitled the Tapatoru (triangle) Model 1 and Tapatoru Model 2 will be introduced and explained. These distinct language revitalisation paradigms illustrate the core ingredients needed in effective language revival and illustrate the positioning and function of the media within these strategic models.
