A hulking strike runner, van der Merwe was part of the South Africa squad that finished runners-up at the 2014 Junior World Championship alongside now World champions Handre Pollard and Jesse Kriel.

He averaged a try every other game for Edinburgh and was named PRO14 Players’ Player of the Season for the 2019/20 campaign. He made a try-scoring Scotland debut in the home win against Georgia in October 2020 before notching in both Florence and Dublin, and scored the only try of the game in Scotland’s 2021 Calcutta Cup victory against England at Twickenham.

Van der Merwe’s blistering form brought about a 2021 British & Irish Lions call-up, during which he had the distinction of starting in all three Test matches.

His prolific international form has continued since, and he now sits second on Scotland’s all-time try-scoring list after a sensational hat-trick against England in the 2024 Guinness Six Nations.

During the 2024 Skyscanner Americas Tour Duhan cemented his place in the history books, first becoming Scotland Men’s joint top try-scorer with a score against USA before scoring his 28th try against Uruguay to become the solo leader.
