Graham started his senior rugby career in Canterbury and turned out for Canterbury"s A, B and Under-21 teams while studying to be a Chemical Engineer at the University of Canterbury. He made such an impression that he was signed up by the Chiefs ahead of the 2015 Super Rugby season.
He made one Information Technology Management Cup appearance for Canterbury in 2013 before shifting north to link up with Taranaki upon completing his university degree. Although he started out his career as a tighthead prop, Graham was used to great effect in the loosehead prop position by Taranaki during their successful 2014 Information Technology Management Cup campaign.
