"We're kind of freaking out a little about what we're supposed to look like and [how] we're supposed to turn out. Red carpets are terrifying - I'm going to have to practise my smile in the mirror."
Broods are finalists for the people's choice, single of the year, and breakthrough artist of the year awards.
Georgia said it was reassuring to see their album Evergreen - which was produced by Lorde's producer, co-writer and engineer Joel Little - reach gold status in New Zealand.
"We're pretty bloody proud of ourselves to be honest. It's a really good reassurance that you've done a pretty good album."
The awards will be held at Auckland's Vector Arena on November 20.
Little won two of the event's early prizes last night.
The technical category awards were given out at an event at the Pullman Hotel in Auckland, and Little took out the best producer and best engineer awards for his work on Lorde's debut album, Pure Heroine.
