Key Points:

Two varieties of Kit Kats were recalled today because of the possibility they might contain small pieces of plastic.

The voluntary national recall was announced by Nestle New Zealand, the manufacturer.

The affected products are Kit Kat Caramel 65G and Kit Kat Cookie Dough 65G, with all "best before" dates up to and including February 14 next year.

Corporate services manager Maurice Gunnell said the company believed the plastic entered the packs during the production process.

The company was recalling the products as a precaution and consumers should ensure they didn't eat the specified varieties.

Consumers who had such Kit Kats should return them to where they were bought for a refund.

Mr Gunnell said no other Kit Kat products were affected.
