KP has been forced to re-think the pack size and price of Hula Hoops Shoks due to poor sales.

It has reduced packs from 55g to 40g and marked packs at 39p, down from 47p.

A buyer for one major wholesaler said the brand had not performed “as well as expected” in the larger size. However, she said the new size and price should provide a better offer for consumers.

The bagged snacks specialist is also revamping its core Hula Hoops range with a new look, two new flavours and £10m worth of marketing support - a rise of £1.5m on last year.

On shelf at the beginning of next month, Bacon & Ketchup flavour replaces Sizzling Bacon, with Cheese Toastie taking over from Cheese and Onion. Salt and Vinegar has been reformulated.

New packaging emphasises the shape, with a large hoop on the front. It includes a phrase associated with each flavour, such as ‘Say Cheese’ for Cheese Toastie. The back includes ‘Hoop-tastic’ ideas for playing with the snacks. Redesigned multipacks more clearly indicate the number of bags.

Ad support kicks off with posters in September, followed by sampling, and focuses on an individual flavour according to which is the most popular in a region. TV advertising is also scheduled and is likely to feature ‘fictional ambassador’ Steve Threlfall.
