WELLINGTON (Reuters) - World Cup winner Sonny Bill Williams will return to New Zealand to switch codes again in 2015 in a bid to win another Webb Ellis trophy plus a gold medal in rugby sevens at the 2016 Rio Olympics.
The 28-year-old is to play for rugby league's Sydney Roosters, the club he helped to Australia's National Rugby League (NRL) title this year, in 2014 before rejoining the Waikato Chiefs on a two-year contract.
