Mrs Barbeau said the family had always loved cricket, with her son playing the game from school age.
"My husband has been following it [the World Cup] quite closely, I don't get to watch all the games because I am working but I feel sorry for whoever is losing ... we are definitely sitting on the fence with that one," she said.
Mrs Barbeau's son-in-law, Jean-Pierre Joubert, said whichever side won he would be in for some ribbing from either his New Zealand or South African friends
Mr Joubert, who moved to New Zealand eight years ago, said he always supported the Black Caps because his two children Joshua, 8, and Chelsey, 6, were born here.
He said there had always been friendly rivalry in the family when the two nations played and betting on who would win today's game had already begun.
