Alexander James "Ali" Williams is a New Zealand rugby union player at the position of lock. He currently captains for the Blues in Super Rugby. In 2008, he played for the Crusaders and in 2010 signed on loan for Nottingham in the RFU Championship. He played for the All Blacks between 2002 and 2012. He was in the All Blacks squad for the 2003, 2007 and 2011 World Cups. In 2005, NZ Rugby Almanack chose him as one of its five players of the year. An advert he commentated for a product his company sells, "Water for Everyone", was found by the Chairman of the Advertising Standards Authority New Zealand to have potentially broken some Codes of Advertising including the codes of advertising to children. The advert was discontinued so did not go before the full ASA board, thus the case was considered settled.
