In 1958 he began working for Burns Philp as a copra shed clerk, where he remained until 1964.[3] He later became a farmer and entrepreneur.[4] He was first elected to the Legislative Assembly of Western Samoa in a by-election in January 1981 following the murder of MP Ron Berking.[1] He was re-elected at the 1982 Western Samoan general election, and at every successive election until his retirement in 2001. During his political career he served as Minister of Agriculture, Minister of Transport, and Minister of Public Works. In 1994 while Minister of Civil Aviation he was named in auditor-general Sua Rimoni Ah Chong's report over his role as chair of the board of Polynesian Airlines, which lost millions of dollars.
