Braydon stormed onto the provincial rugby scene in 2017 with a standout season for the championship Canterbury team..
Originally from Auckland, he joined the Crusaders Academy in 2015 with a scholarship. Braydon was part of the victorious New Zealand Under 20 team that lifted the Junior Rugby World Cup in Georgia in 2017 and went on to be named Canterbury A First Year Player of the Year at the Canterbury Rugby Awards later that year.
He made his Crusaders debut in 2018 and his Test debut for the All Blacks in 2019. Braydon returns for his fifth year with the Crusaders in 2022 following an unfortunate run of injuries which saw him sidelined for most of the 2021 season.
