Paora Josephs: Koro Taku Tai Moana Turoa as a child was brought up on the Whanganui river. He told me that he was raised as a Tohunga and had a total recall from the age of 5 years. Upokotauaki at Patiariroa (Jerusalem) was commonly known as the Whare wānanaga where Tohunga received their formal training in the Whanganui area.
