[1] Born and raised in Waikato, Gatland attended Southwell School where he played first XI cricket & first team Rugby.

[2] Gatland made the Waikato squad for the 2015 ITM Cup, but due to the emergence of future All Black Damian McKenzie in the number 10 jersey, his game time was limited to just a solitary substitute appearance against the Bay of Plenty.

His decision to move to Harbour proved to be an enlightened one as his form at Fly Half saw the more experienced Matt McGahan shifted to fullback to accommodate him.

Gatland played all 12 games during the 2016 season and scored 123 points as North Harbour won the Mitre 10 Cup Championship with an upset victory away to Otago and secured a place in the 2017 Premiership.

Gatland became a regular starter for the Blues in the 2018 Super Rugby season, with injuries to Stephen Perofeta and Otere Black.
