Onosai Auva'a (born 7 February 1985 in Auckland) is a New Zealand rugby union footballer who has played for the Auckland Blues Super Rugby team and also for Auckland in the ITM Cup.[2] Auva'a has signed for Sale Sharks on a two-month loan contract lasting until February 2012, but an outstanding performance against Leicester Tigers in the Aviva Premiership would appear to further Auva'a's aim of a long-term contract with the Sharks.
At the 2006 Commonwealth Games he was part of the New Zealand Sevens team that won a gold medal.[3]
