Educated at Avele School, Vaelaʻa spent three years working for Burns Philp before joining the police. After six years in the police force, he worked for a sawmill and then for E.A. Coxon.[2]
In 1954 he was elected to the Legislative Assembly from the Vaʻa-o-Fonoti constituency. He was re-elected in 1957 elections and was a member of the 1960 Constitutional Convention and a signatory of the independence constitution. He was re-elected again in 1961, and following the 1964 elections he was appointed Minister for Health. After the 1967 elections he was moved to Minister of Justice. Although he was re-elected in 1970, he was left out of the new cabinet.
