Former All Black five-eighths Lima Sopoaga has warned that New Zealand's global rugby dominance is at risk.
The Highlander who moved to British club Wasps this season, has warned of a growing exodus of players in their prime, who are making ''business decisions'' to seek their fortunes in Europe, reports the Daily Mail.
For years, New Zealand have managed to hold on to the bulk of their leading lights by refusing to pick players based abroad. The allure of the black jersey guarded against a mass migration, but Sopoaga believes that others are ready to give their best years to clubs offering lucrative contracts in the northern hemisphere.
''I do think that things are starting to change and players are starting to wise up,'' he said. '''They realise that it's a business these days. When you've got it, you've got it, but when you don't, clubs aren't going to be afraid to cut you.
''For players these days, a lot of us are starting to talk to each other more and talk about experiences and about how we can benefit from the game, because it is a business and it can be pretty cut-throat. That's the way it is. Players are starting to wise up to that.''
