"There are now more paintings than Creative Northland can hang," she said.
"We're asking the community, or local businesses, to hang a couple of the paintings in their window."
They also need screens, trestle tables and plinths to display the artworks at the gallery.
"Artists have been incredibly generous and the artwork is stunning," Greenwod said.
"It's so good they've given the donations and kindness to Ukraine; we just need help to display it somehow."
The group - called Arts for Ukraine - is determined to support humanitarian aid in the eastern European country and give ongoing care for those still under Russian occupation.
It has already raised more than $1000 which has been transferred to the United 24 bank account set up by the Ukrainian government.
All proceeds from the upcoming auction will also go to the account.
