Bunnings has announced a new collectible campaign for kids starting January 14.

The Building Block collectibles are designed to complete the fan favourite Bunnings Block Warehouse, which is currently available in stores.

The first “add-on” is a Building Block Bunnings truck, described as a replica of “the quiet hero, always ensuring the shelves are fully stocked with more than 40,000 products for customers to choose from.”

Every month until May a new mystery collectible will be available in stores.

“Each add-on will be a replica of features you can easily spot inside a Bunnings Warehouse so that customers can collect and build some of their favourite in store features,” a Bunnings representative said.

The collectibles will cost $10 each and are available nationally, online and in-store, in limited quantities and while stock lasts.
