These include Reduced To Clear, Diversion Maze Park, Reading Cinemas, Rotorua Aquatic Centre, Rotorua Duck Tours and more.
Registrations open at 9.30am and the dig starts at 10.30am. This year children need to be registered and it is limited to the first 400 children.
The Hits Rotorua presenter Paul Hickey said it was neat to see the smiles and changing reactions on the children's faces, from getting into the excitement of the dig, to finding a stick, then collecting their prize bag full of goodies.
"You don't get much for free nowadays, so it is pretty rewarding for us to do all the work and make this happen for the young families in our community.
"However, it wouldn't be possible without the generous support of other like-minded businesses."
McDonalds Rotorua franchisee Linley Parry said McDonalds Rotorua was pleased to be the main sponsor of the fun family event again.
"It's just fantastic it has gained such enormous support from day one.
"We have provided a bounty of prizes, including sporting items so the families can stay around and enjoy the day.
"We hope everyone has another memorable day and enjoys being together in our wonderful community."
This year there are also two bikes to give away thanks to The Warehouse.
One will go to a V.I.D (Very Important Digger) from entries Hickey has had on his show all week.
Weather updates and any postponement details will be available on The Hits Rotorua Facebook page today.
