McKenzie, taking over from fellow All Black Barrett as the star import at the Tokyo Sungoliath, was instrumental in their 60-46 win over the Brave Lupus in the opening weekend of the revamped 2022 League One season.
McKenzie kicked nine goals - four conversions and five penalties - for 23 points.
Playing at fullback, he sparked plenty of counter-attacks in the high-scoring affair.
Recalled Wallaby Sean McMahon scored three tries for the Sungoliath who are looking to go one better this year after finishing runner-up in 2021.
