In 2017 Williams was part of the Blues super rugby squad. Coming back from injury, his first game for the Blues was in April against the Highlanders, a game where he made headlines for taping over the BNZ logo on his jersey. After a patchy return from injury, Williams looked back in form when the Blues drew with the Chiefs on a rainy Auckland evening. Williams delivered a man of the match performance to help the Blues defeat the British and Irish Lions, 22–16. With time running out and the Lions in the lead, Williams gave an offload to Ihaia West to score the match-winning try.
