Because of Nock's promise as a school boy at Saint Kentigern College the Blues Super Rugby franchise announced in June 2015 that they'd signed him on a 3 year contract before he'd even played any national provincial championship rugby. He gained a season's experience at provincial level before joining up with the Blues ahead of the 2016 Super Rugby season. He spent the season as third choice halfback behind Bryn Hall and Billy Guyton. When Guyton fell ill prior to the match against the at Eden Park, Nock was called into the Blues 23 man squad and debuted as a second half replacement for Bryn Hall in a 19-23 loss.
