Sonny Bill Williams is not the only top rugby player in New Zealand to exercise his right to not promote certain sponsors.
It is understood that others have had issues with fast-food giant KFC and have alerted New Zealand Rugby that they would rather not appear in advertisements. Even those who do have negotiated strict rules with the help of their players' association.
Some have felt that professional athletes backing a fast food company would send the wrong message when obesity, particularly among children, is becoming such an issue in New Zealand. Those that do appear in the television ads are never seen eating the product.
It boils down to individual choice, and while we don't know why Williams taped over the BNZ logos on his Blues jersey in his debut for the team against the Highlanders in Dunedin, many have surmised it is related to his Muslim faith.
Before the match he shared on social media a picture of the lower portion of his jersey, and the fact it was embroidered with the name of his wife Alana and their two daughters Imaan and Aisha.
