Georgia revealed she'd ditched her shoes at the awards, because she'd "had enough" of them.
She and her brother also collected Tuis for best group, best pop album for Evergreen, and the radio airplay record of the year for their single Mother and Father.
"It's crazy. It's times like these that you really realise, like, wow," Georgia Nott said.
"We have actually done so much, not even this year, but in the last two years. It's pretty surreal to have it in the shape of five or four awards. It's pretty crazy."
At last year's awards Broods was named the breakthrough artist of the year.
All the recognition had left the duo "proud and humbled".
"We're going to try and keep this going."
For now, Georgia Nott said she was looking forward to Christmas at home in Nelson and "hanging" with her parents and sisters.
