His trout, entitled Gotcha, appealed to the team from BNZ Rotorua, according to assistant manager Amy Callaghan.
"I just think it is a really skilful drawing and a bit of Rotorua," she said.
The bank has a collection of artworks from the auctions over the years.
Topping the stakes was 6-year-old Cory Josephs' Beads of Life artwork, which went for $500, followed by Paige Maxwell's picture Mickey Mouse, My True Bead of Courage which went for $480.
It's the third year the 5-year-old has created a piece of artwork.
She said she chose to draw her Mickey Mouse toy as it had been through "everything" with her - even sporting its own hospital name tag.
Professionals operations manager Kylee Douglas said they were "over the moon" with the way the event went - with more than 330 people turning out.
While the total hadn't been tallied, she said it was likely to be just over the $20,000 target.
She said they were grateful for the generosity of the community.
