The Ospreys have started the domestic season well and currently find themselves top of the RaboDirect table having won all six of their opening league matches.
And with their first Heineken Cup tie against Biarritz Olympique under two weeks away, Fotuali'i is looking for game time ahead of the opening clash.
"I'm hoping to get some decent game time and get involved quite a lot," he said.
"I'm going to try to nail down a starting spot and then play well.
"I want to learn when I'm here as well, learn about the northern hemisphere and hopefully give a little bit of my experience from the Crusaders. I'm looking forward to getting involved."
