Tonga chose to drive to Maitua's unit, and found Maitua attempting to take his own life. Tonga believes that had he even arrived 10 seconds later, Maitua would not have survived. Tonga and Maitua told their story on the NRL Footy Show in June 2014 as an attempt to help remove the stigma around mental illness in league. On 9 July 2014, it was confirmed that Tonga had signed a contract to play for the Super League club the Catalans Dragons in 2015. He made his Super League début in round 1 against the 2014 Champions, St. Helens. He scored his first ever Super League try against the Warrington Wolves in round 3.
