Packets of shaved roast chicken are being recalled because of undeclared soy.

The Hellers shaved roast chicken 200g with a best before date of 10 December was being recalled, the company said.

Hellers chief executive Christine Cash said the wrong ingredient label was applied to the back of pack.

"While the label states 'May Contain Soy', any people with a soy allergy should not eat this product due to the presence of soy."

It was safe for people without a soy allergy to eat, she said.

"As soon as we detected the issue, we made contact with New Zealand Food Safety to conduct a public recall and have notified all relevant supermarkets."

Cash apologised for any inconvenience caused.
