Labour's ethnic communities spokesperson Phil Goff is calling for the Government to clarify where and when Sikhs can wear a kirpan.
Seven Sikh cricket fans were barred from entering Eden Park to watch India play Zimbabwe in a Cricket World Cup match on Saturday because they were wearing kirpans.
The kirpan is a ceremonial sword or dagger carried by Sikhs for religious purposes.
To possess one is not unlawful in New Zealand but the kirpan is considered by the ICC to be a weapon.
Yesterday, Prime Minister John Key said at a press conference that the ICC was wrong in barring Sikh fans from wearing kirpans at World Cup matches.
