Things like booze culture to organ donation to life without kids or women in governance could be discussed, she said, it really just depended on what the women attending were passionate about.
The event only took 100 women, who applied and were selected by organisers.
Applicants came from around and outside the Bay and nearly half of the selected women were from the Bay of Plenty.
Ms Wallace said the women were selected to reflect a wide variety of ages, ethnicities, backgrounds and passions.
"We wanted to get as many voices as possible."
Ms Wallace attended the event in Wellington and knew it would be a hit in the Bay of Plenty.
Mount Maunganui's Sarah Bunker, owner of writing agency Away With Words, was one of the 100 women going to the unconference.
"I've never been to an unconference or even knew what it was . . . but for me this is a year of adventure and trying new things," Mrs Bunker said.
She said she was looking forward to meeting all the powerful, different, inspiring, passionate but "also just normal" women that she would not have met in her life otherwise.
"It will be great being able to share good energy with other women who are all there because they have something to give but also make connections and learn from everyone else."
