"We've had quite a few enter - hundreds of couples have responded. It's quite a niche thing to do. You have to be prepared to have this intimate moment broadcast on air," he said.
The radio station is looking for 10 finalists with the public then voting two weeks before the special day on who they wanted to see marry, Mr Dickey said.
The Edge FM had previously run wedding competitions and were looking forward to the wedding, he said.
"We're really excited ... we love weddings at The Edge."
Staff at Rotorua's Bath House are excited about the special event also.
Rotorua Museum sales and marketing manager Jo Doherty said it was fitting the Bath House would host one of the first gay weddings in the country with the place now being opened up for such events.
"We are so excited. It's an historic moment in New Zealand history."
The museum will be recording the event.
"It's a serious but awesome occasion," she said.
