On 13 October 1975, a historic land march reached the grounds of Parliament in Wellington. The elderly, articulate woman leading the way became Te Whaea o te Motu (Mother of the Nation). Whina tells Dame Whina Cooper's life story, from her achievements as a Tai Tokerau leader to the hīkoi that made Māori land rights a key national issue. In this trailer, the teenage Whina (Tioreore Ngatai-Melbourne) experiences the injustice of land confiscations. Adult Whina (Miriama McDowell) takes up the mantle for Māori women, and elderly Whina (Rena Owen) delivers a powerful kōrero (speech).
