The glitzy event at ASB Stadium in the Auckland suburb of Kohimarama will raise money for Kidney Kids of New Zealand.
Guests at "Corporate Takeover" will include sporting celebrities including heavyweight boxer David Tua. There will also be a professional and amateur fight at the black tie event, which is being co-hosted by Awen Guttenbeil and Hayley Holt with celebrity guest judges Neil Waka and Ben Mitchell.
Both Buckwheat and Miss Ribena have been sweating it out at the gym to get into prime shape for the bout and it should be a fight to remember.
The event begins at 6.15pm and door sales are $30.
