The Rototuna New World is the only supermarket affected by the recall.

Hamilton's Rototuna New World supermarket is recalling a batch of sausages, fearing they may contain pieces of plastic.

Customers are asked to check if they've purchased any Honey Mint & Rosemary Lamb Sausages in any weight with best before dates of July 5, 8, 9 or 12.

The Ministry for Primary Industries issued the warning on Friday night and said the Rototuna supermarket on Horsham Downs Road was the only New World affected.

"There have been no reports of injury," MPI said. "However, if you have consumed this product and have any concerns about your health, seek medical advice."

Customers will receive a full refund.
