Fresh oysters sold from a Northland shop and certain batches of packaged oysters are being recalled due to reports of people becoming ill after eating the shellfish.
Paroa Bay Oysters, which has a factory shop on State Highway 1 just south of Kawakawa, is recalling some of its Paroa Bay brand Raw Oysters pottles as well as all fresh oysters sold from the shop between July 30 and August 5.
The packaged oysters affected by the recall are 200ml pottles with batch numbers 3572 and 3574 to 3583.
Jenny Bishop, of New Zealand Food Safety, said anyone who had purchased those oysters should return them to the shop for a full refund or throw them out.
The oysters were suspected in seven reported cases of foodborne illness reported in Northland and Auckland.
