Siale Piutau (born 13 October 1985, in Auckland, New Zealand) is a rugby union centre who represents Wasps RFC in the English Aviva Premiership. Although born and educated in New Zealand, he represents Tonga internationally. He is the elder brother of New Zealand player Charles Piutau.
Piutau joined Counties Manukau during the 2006 Air New Zealand Cup. Over the ensuing few seasons, his solid game on both sides of the ball cemented his place in midfield for the Steelers.
Lining up next to former All Black Tana Umaga in midfield, Piutau was in the 2010 ITM Cup for the Steelers. He started every game for Counties, and was one of the club's top performers over the course of the season. As a reward for his efforts, he was named the 2010 Counties Manukau Player of the Year. His season was also highlighted by the earning of his 50th cap for Counties in the final game of the year.
For the 2011 Super 15 season, Piutau was signed by the Highlanders and emerged as a key squad member, making 13 starts and scoring 3 tries. In 2012, he was limited by injuries and made only 5 appearances. Following the season, he left New Zealand to sign in Japan.
