The following season saw Harris-Wright play more regularly, due to the retirement of first choice hooker John Fogarty. New Leinster coach Joe Schmidt regularly used Harris-Wright as a replacement in the league and in Europe. Harris-Wright made his European debut for Leinster in a 2010–11 Heineken Cup pool stage game against Racing Metro on 9 December 2010. He made his first start for the team against Ospreys in the league on 28 November 2010. Harris-Wright made 11 league appearance in total for the season, with all but three of these coming from the bench. Harris-Wright played in four Heineken Cup games, including the final against Northampton Saints which Leinster won, with all of these appearances coming from the bench.
