Nestlé is driving KitKat sales with two new limited-edition flavours and a £2m ‘break off’ campaign.

KitKat Vanilla, available in four-finger format, and KitKat Chunky Extra Chocolate, RRP 58p, are available to convenience retailers now.

For a limited time, all KitKat packs will have revamped packaging with a series of messages that are designed to suit the consumers of each format.

The brand will be backed by TV advertising from January 18, and the campaign will also include social media, digital and PR activity. PoS is also available to retailers.

KitKat has also introduced a new YouTube promotion across its range.
