|Rugby union career|
Ma'afu was educated at Granville and Ashfield Boys High Schools in Sydney and played rugby league as a youngster in the Balmain district before starting up with rugby, aged 11. Ma'afu first made his mark at representative level in the NSW Under-19 side in 2001 and 2002, later featuring in the Waratahs Academy through 2004 and 2005.
He signed with the ACT Brumbies in 2006 and made his Super Rugby debut in 2007. Ma'afu made the Australia A squad the same year, ending his year with a late-season appearance for the British Barbarians club during its 22-5 win over the new Rugby World Cup holders, South Africa. In the NSW club competition, after spending two years with Warringah, in 2009 Ma'afu returned to West Harbour, where he played alongside his brother Campese.
Before the commencement of the 2013 Super Rugby season Ma'afu signed with the English Premiership side Northampton Saints ahead of the 2013/2014 season. Ma'afu became a regular in the side, helping them to victory in both the Premiership and the European Challenge Cup. On 13 June 2015, Maafu would join top French club Toulon in the Top 14 on a two-year contract. Ma'afu returned to Aviva Premiership to sign for English club Gloucester Rugby
Ma'afu's first test cap was in 2010 against Fiji, where he had the unusual challenge of marking his brother, who was also playing on debut. The pair became just the fourth set of brothers to oppose each other in Tests, and the first to achieve this feat when both were on debut. Subsequent tests in 2010 against England, Ireland, and South Africa completed a strong year for the prop.
