The New Zealand Rugby Union is not revealing who it will back in the vote for chairman of the International Rugby Board in Auckland on Wednesday.
Incumbent Bernard Lapasset of France is being challenged by vice-chairman Bill Beaumont of England.
NZRU chief executive Steve Tew says there has been plenty of lobbying going on over the past few days.
The views of the two candidates on the future governance of the World Cup will no doubt play a large part in the vote.
SANZAR unions (South Africa, New Zealand and Australia) say the tournament has cost them $50 million in lost revenue.
Tew and former All Black captain Graham Mourie are New Zealand's two representatives on the IRB Council. A simple majority of the 26 votes will decide the contest.
