Cadbury is reviving its Wispa and Twirl chocolate eggs for the first time in five years for next year's battle of the Easter eggs. It has also followed rivals Nestlé and Mars by cutting the amount of packaging across its Easter range.

The all-new Wispa and Twirl eggs, which will each contain three chocolate bars, will carry an rsp of £5.59. Consumer demand for an Easter egg version of Wispa had been phenomenal since it returned to the shelf permanently this year, said Keith Widelski, Cadbury category manager for Easter.

"After the huge buzz that prompted Wispa's return as a chocolate bar, it was a no brainer to bring it back as an Easter egg," he said. "Along with the Twirl egg, these two iconic additions to next year's egg range will generate excitement."

Pack designs for the Cadbury Dairy Milk egg and its Caramel variant have also been revamped with brighter colours but the luxury vanilla Cadbury Dairy Milk egg launched this Easter has been delisted due to poor sales.

The company has also cut the amount of plastic and cardboard by 25% on its medium eggs and by 30% on its large shell eggs. Nestlé cut the amount of packaging across its shell range by 30%, and eliminated plastic inserts in 80% of its eggs.

Widelski claimed, however, that Cadbury would be saving 302 tonnes of cardboard this year, which was more than its rival.

"We were also the first to instigate the Easter packaging reduction trend by launching our unboxed eggs range this year, a move that won us the Best Green Packaging award at this week's Green Awards," added Widelski. "It's also worth remembering that some consumers actually want packaging as they want a packaged gift that can be wrapped or mailed."

Cadbury's CSR report, launched last week, included news of the Cadbury Cocoa Partnership, a £45m investment over the next 10 years to guarantee a long-term source of quality cocoa and a structured sustainability programme for farmers in Africa.
