Dixon was retained for the All Blacks' 33-man squad for the 2016 Rugby Championship. The All Blacks won the competition but it was a personal disappointment for Dixon, who only managed four minutes of game time in the competition, mostly due to the dominance of Savea and Squire as replacements off the bench. Those four minutes came on 1 October 2016 when he replaced All Blacks captain Kieran Read 76 minutes into the All Blacks' 36–17 over Argentina. Dixon made one more appearance for New Zealand in 2016, playing the full 80 minutes against Italy on 12 November. Dixon scored his first international try against Italy, scoring in the 62nd minute while also setting up Steven Luatua for his try.
