Nestlé has launched a new addition to its Kit Kat range, the Kit Kat Chunky3, which features the brand's signature wafer, topped with three breakable chunks containing three separate textures - fudge, crisp and sauce.

The new chocolate bar will be available in three flavours - chocolate, caramel and cookies & cream.

The new line was developed over two years from an idea sourced from the factory floor at the Nestlé factory in Campbellfield in Melbourne, which produces the majority of the company's chocolate in Australia. Nestlé Australia's Head of Confectionery, Mr Andrew McIver, said other markets around the world had expressed an interest in the Australian-developed Kit Kat Chunky3.

"This is a really innovative step in terms of the next big thing for Kit Kat and shows that great ideas can come from anyone in the company," he said.

"Kit Kat Chunky3 follows on from another home grown idea - the Kit Kat block - which was developed by employees from the same factory."

As part of Nestlé's global $117 million Cocoa Plan, the Kit Kat Chunky3 bars will be manufactured using Utz Certified sustainable cocoa.

Kit Kat Chunky3's launch will be supported by an extensive TV, digital and outdoor advertising campaign, beginning on Sunday June 12.
