LSG Sky Chefs products have been removed from supermarket shelves after a worker tested positive for COVID-19.
The woman, her partner and their daughter had all contracted the virus in the community and were now in a quarantine facility, the Ministry of Health revealed on Sunday.
The mother works at LSG Sky Chefs, a company which does laundering and catering for airlines. It also provides food to supermarkets, and these have been withdrawn from the shelves.
"The health and safety of our customers and team members is always our top priority," a Foodstuffs spokesperson told Newshub.
"Some Foodstuffs stores in North Island regularly sell ready meals, sandwiches and muesli pottles which are produced by LSG Sky Chefs.
"Taking an 'abundance of caution' approach, all LSG Sky Chefs produced products have been removed from our shelves as a precautionary measure until we understand more about the source of the recent community cases."
While LSG Sky Chefs does have a connection to the border, officials say they are keeping an open mind about the cases' source.
While genomic sequencing shows that the three cases have the UK variant, there is no direct link between them and any other positive cases detected in New Zealand to date.
So far, 42 close contacts of the infected family have been identified. They include students and teachers at Papatoetoe High School, which one of the cases attends.
Seven of the nine colleagues of the case who works at the company have tested negative for the virus. More results are expected to be announced later on Tuesday.
