While not included in the Tasman squad that was named for the 2017 Mitre 10 Cup season,[4] Salmon made his debut for the Mako on 27 August 2017 against Manawatu.[5] He went on to play 6 games for the province in his first season.
Salmon was part of the Tasman team that won the Mitre 10 Cup in 2019 for the first time.[7] He was again part of the Mako side that won their second premiership title in a row in 2020.[8] Tasman again made the final in 2021, with Salmon coming off the bench, but the Mako this time lost 20–23 to Waikato.[9]
