Wiremu Ohia was born at Papamoa and was educated at Papamoa Native School and Tauranga College. After he finished school, he wanted to join the airforce but his grandfather wouldn’t let him go to war so he remained at home and worked on the family dairy farm. In 1942 he married Hinemanu and together they worked on their dairy farm at Welcome Bay. Ohia was chair of the Whetu o Terangi marae committee and chair of the Tauranga Moana District Māori Council. He was Tauranga representative on the Waikato District Council and became chair of the Tauranga Moana Trust Board. Ohia worked for Māori Affairs, continued working as a dairy farmer and eventually moved into orcharding.
