Did you get any further info?
I'm descended from Hori Waaka and Panatita Te Awanui and trying to trace whakapapa. I believe Ngāti Kirihika Hapū of Ngāti Raukawa Iwiw - though not sure if both 'Te Kauri' side and 'Te Awanui' side are Ngāti Kirihika, or just one. There's a lot of mention of Te Kauri, Waaka, Awanui and Kiritapu in this document which indicates Te Kauri and Waaka names as part of Ngāti Here. The document explains that Ngāti Here were a hapū of Ngamarama which occupied the Tauranga area before the migration of the main waka (Tainui, Te Arawa etc). Over the years the hapū of Ngamarama have been absorbed into Raukawa and Ngāti Ranginui (Ngāti Kahu, of Ngāti Ranginui was originally Ngāti Kahu of Ngamarama). Ngāti Here seems to have been absorbed into Raukawa - perhaps into Ngāti Kirihika(?).
