In Kia Ora, Good Evening, veteran journalist and newsreader Mike McRoberts steps out of his comfort zone. The documentary follows McRoberts as he commits to learning te reo Maori and reconnects with his Ngāti Kahungunu roots. In his public role as a polished newsreader, McRoberts hid his whakamā (shame) at not speaking te reo and being a 'real' Maori. His whānau discuss their mixed heritage and the racism their parents experienced as a couple. McRoberts' emotional exploration of his identity includes receiving a tā moko and delivering his first whaikōrero (te reo speech) on his father's marae.
