Warriors sign Chiefs lock
The 22-year-old arrived in Glasgow on Saturday and started training with his new teammates at Scotstoun on Monday.
Alainu'uese is a product of Wesley College in Auckland, a school whose alumni include current All Black Malakai Fekitoa, Ulster's Charles Piatau and the great Jonah Lomu to name just a few.
The giant lock played six times and scored three tries in his first season for Waikato. His performances earned him a call-up to the Samoa Under-20s squad due to his island heritage, where he played five times and scored one try.
Last season Alainu'uese made two appearances for Dave Rennie's Chiefs in Super Rugby and this season he has started seven times in the National Provincial Championship for Waikato.
Speaking to glasgowwarriors.org about his new chapter, Alainu'uese said: "I'm really excited about joining Glasgow.
"I've spoken to Dave Rennie about the move and he told me great things about the club and it made me want to join.
"Everyone in New Zealand knows that Glasgow Warriors is a great club and there are good people here.
"I watched Corey Flynn playing when I was growing up and Jarrod Firth spent some time at the Chiefs, so it'll be good to get to know those boys, as well as the rest of the squad.
"From what I've seen Glasgow like to throw the ball around and play a fast game and that's the way I like to play too.
"I'll give it my best over here and if an opportunity comes I'll take it. I just want to give my all for Glasgow."
Glasgow Warriors head coach Gregor Townsend said: "Brian has a real physical presence and has played well for Waikato in the NPC this season.
"He has the ability to play an offloading game and will help our set-piece play.
"With Greg Peterson, Scott Cummings and Tjiuee Uanivi currently injured, we're delighted to secure the services of such a quality second-row, and we're looking forward to integrating him into our squad."
