Mr Gollan said the Olympians would be interviewed on stage.
Edward said she wanted to attend because the Rotorua community had been a great support during her years of rowing, right from high school, and there were great charities to raise money for.
She said she was looking forward to talking on stage about her Olympic experiences in Rio and London and her future in the sport, as well as catching up with familiar faces.
Auction leader Chris Smith said a contact in Australia had donated a framed and signed Eagles guitar.
The frame also includes photographs of the band and is signed by the four original members. A certificate of authenticity is included.
Mr Smith said it was nice to have an item that was a bit different to the norm.
"You can't beat the Eagles, they are a super-band. Getting something like this would be very unique."
Mr Smith said there were close to 140 items up for grabs and there would be 18 live auction items.
