Gunnedah's Hay and Harvest Festival will now be held in September next year, six months after the original date.
The date was pushed back by the event's working group so it "doesn't impact" the Day of the Devils event.
"We're making sure we support everything," head of the working group Kathryn Blinman said.
Ms Blinman said the exact date in September was yet to be confirmed, but plenty needed to be organised before then.
"It's going to take a lot of team effort and investment in the community and it's going to have a great impact on our tourism for Gunnedah hopefully," she said.
"We are calling to community members who want to be involved ... whether it's small to large or looking at being a sponsor, any interest people would like to have they're welcome to lodge it with council."
The event will still be held at Gunnedah's Riverside Racecourse.
Those interested in getting involved with the event are encouraged to contact Gunnedah Shire Council on 6740 2100.
Gunnedah's councillors voted to merge the event with the old Porchetta festival at a recent council meeting.
Porchetta was a popular Italian food festival held in town, but after seven years, the event committee called it a day in 2016 because of a lack of volunteers.
The merged event will now be funded through the grant and the festival's seed funding of $17,000 through the federal government's Building Better Regions Fund.
