Incoming All Blacks coach Scott Robertson is reportedly persona non grata at his prospective teams' Rugby World Cup games.

Former halfback and SuperSport pundit Justin Marshall claimed Robertson would be a 'distraction' to the current players, according to New Zealand staff.

Former All Blacks coach Laurie Mains has cast doubt over Robertson's reported ban.

"Anybody can go to the games that wants to go- New Zealand Rugby Union doesn't have any say in that. You can't ban him from games."
