Robinson made his debut for Southland in round three 2008 Air New Zealand Cup against the Hawke"s Bay Magpies. He played majority of his games at fullback rather than his favoured first five-eighth position due to the competitions top scorer Blair Stewart having cemented the role for the season. In 2009 Robinson was selected for the New Zealand Under 20s team for the Junior World Cup in Japan.
Robinson played the majority of the tournament at fullback due to the team"s captain Aaron Cruden being a specialist first five-eighth.
The team went through the tournament unbeaten, defeating England 44-28 in the final. His season continued with Southland making a great start to the competition after being second after 8 rounds of the 2009 Air New Zealand Cup.
His form led to him securing a Highlanders contract for the 2010 and 2011 Super Rugby seasons. In 2012, after two years with the Highlanders, he signed with the Chiefs, with his contract extending until the 2014 season.
He was released by the Chiefs in 2014 after a frustrating injury that kept him out for the entire campaign.
