Tuiloma was first named in the Counties Manukau Steelers squad ahead of the 2016 Mitre 10 Cup where he again linked up with former Bombay coach Darryl Suasua, who was now in charge of the Steelers. Preseason injuries to experienced front row pair Pauliasi Manu and Nepo Laulala opened the door for Tuiloma, who quickly cemented himself as a regular starter in the number 3 jersey. He played all 11 of Counties Manukau's games during the campaign and scored 4 tries, including a memorable hattrick against Waikato as the Steelers reached the Premiership semi finals before going down to Canterbury.[3][4]
In October 2016, it was announced that Tuiloma would take up a 7-month contract with French side Grenoble where he would serve as an injury replacement until the end of the 2016–17 season.[1]
In December 2021 he signed a deal to return to Major League Rugby with Rugby New York for the 2022 Major League Rugby season.[5]
