Auckland mayor Wayne Brown has taken a swing at the Government's $70 million major events fund - while seemingly revealing its spend on bringing Robbie Williams here this year.

Eden Park chief executive Nick Sautner says he can't confirm that figure and Wayne Brown's comments are disappointing.

"The mayor - part of his role is to advocate for our city.  Now, I’m not privy to the investment level. What I am privy to is the fact that the Government took a leadership position on getting major events back into the country."
