Raiha  was daughter of Rawhiri and Ria Waitohi, both of Ngati Toa and niece of Te Hiko  and was senior head of Ngati Toa in the 1890's. Mrs Joshua Prosser, or Raiha Puaha, as she was known amongst her own people, succumbed to an attack of double pneumonia, and Porirua lost a well-known member of the Maori race. She was one of the leading women in the Ngati Toa tribe and grandniece of the great Te Pehi, an early warrior in the  days when Porirua was a whaling station. Te Pehi was famous for the fact that he once boarded a whaler off Kapiti Island, and refused to leave the ship, demanding to be taken Home to see King George IV. His wish was granted, ana subsequently he was presented to the King, and a model of his tattoo was taken. Raiha Puaha, or "Granny, as she was known amongst her people was of a most lovable disposition, and a large attendance at her tangi was held over her remains at Porirua. She left a brother (Matengo te Hiko), a husband (J. H. Prosser), and one son (D. J. Prosser). Relatives from as far North as Tauranga and as far South as the Bluff attended.
