Thousands are expected to attend the Ashhurst-Pohangina Lions Club Smallholders' auction on January 25, with the gate takings going to the Palmerston North Rescue Helicopter.
Organiser Ron Farrugia said the event is on 8h/a of McDonald's farm, 695a Pohangina Rd, 7km north of Ashhurst.
Parking is also on the site.
Farrugia says people can bid on plants and trees, chooks and ducks, small animals, farming equipment and household goods.
"There's always the quirky and unusual lots," he said, with three auctions being held at the same time throughout the day.
