New Zealand referee Paddy O'Brien has been chosen to officiate the North v South rugby aid match at Twickenham on March 5.
O'Brien, who took charge of the RBS 6 Nations game between Italy and Ireland on Sunday and will referee this weekend's showdown between England and France, will be assisted by fellow New Zealander Paul Honiss and Frenchman Joel Jutge, both of whom will be touch judges.
Meanwhile, former All Blacks lock Ian Jones has been appointed as assistant to southern hemisphere coach Rod Macqueen.
The proceeds from the International Rugby Board-organised match will go towards helping the victims of the Asian tsunami.
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
