It was announced on 5 June 2017 that Ma'afu would link up with fellow Saints Api Ratuniyarawa and head back to Fiji for the summer international.[6]
After 2 seasons with Northampton, Ma'afu initially signed for Ealing Trailfinders before subsequently joining Leicester Tigers for the 2018/19 season.[7] On 15 May 2019 he was announced as one of the players to leave Leicester following the end of the 2018-19 Premiership Rugby season.[8]
