Former All Black Sam Tuitupou has announced he is taking his hard-hitting, high-octane game to the English Premiership, the Blues second five signing a two and a-half year deal with the Worcester club. Tuitupou, who has played nine tests for the All Blacks, unveiled his plans live on Newstalk ZB on Monday evening, the 25-year-old key member of the Blues backline admitting that he had told nobody -- including his team-mates -- of his intention to head overseas. "It's just time for it," Tuitupou said on radio. "I've got a young family, three kids, and it's the right time for me and my wife to get away and look for a new challenge." He also said he wouldn't rule out, at the age of 25, returning to play again in New Zealand once his commitments in the north finished. "But I've always wanted to play overseas and I guess now is the right time for me to go," he added.
