Angus has played for Auckland, the Blues, New Zealand Maori and the All Blacks in a career that began in 2001. Angus is known for his versatility, as he has played in various positions in the forwards including Lock, Flanker and Number 8.
He was part of the champion Blues Super 14 campaign in 2003 and has captained his province; at the young age of 24.
Since 2008, he has been based in Japan, where he has played a key role in the development of Toyota Verblitz and latterly Coca Cola West Red Sparks.
On his move to Glasgow, Angus said: “I’m really happy to have signed for Glasgow Warriors and I’m excited by the opportunity of playing for a club where there’s a concerted effort to achieve success.
“Since this move became a possibility, I’ve been keeping a close eye on how the team have been performing in the RaboDirect PRO12, and it’s clear they’ve got a tremendous spirit and sense of purpose in what they do.
“They’ve got every chance of making the play-offs and they’ve recruited and retained a good number of players, so it’s a positive environment to be coming into.
“The aim will be to use everything I’ve learned in the southern hemisphere to bring my own influence to the table. My overriding feeling right now is one of real anticipation. It’s a great new challenge for me, and one I can’t wait to get stuck into.”
