He'll be with the Warriors until at least the end of the 2014-15 season.
Since making his Super Rugby debut in 2008, Sean has scored some 24 tries, equaling the record for the most individual touchdowns in a single tournament game when he crossed the whitewash four times against the Brumbies in 2011.
He was a part of the New Zealand U19 team that won the World Cup in 2007, and the U20 side that scooped the 2008 IRB Junior World Championship. Sean scored against Argentina, Ireland and Wales in that latter tournament.
In 2010, he represented the New Zealand Maori team, and commended himself to the British audience with two tries for the Crusaders at Twickenham in their showcase Super Rugby game against the Sharks in March 2011.
Sean has strong family lineage in the game, being a cousin of Wallabies pivot Quade Cooper. He is also related to “Smoking Joe” Stanley, the centre who helped New Zealand win the Rugby World Cup in 1987.
Sean qualifies to play for Scotland courtesy of both his paternal Grandparents who were born in Glasgow.
