Police are looking for four people who were caught on CCTV using a bank card stolen from Starship Hospital to splurge in stores.
A police spokeswoman says she did not know if the card belonged to a patient or a visitor.
On the Auckland City District Police Facebook page, authorities say transactions were made in various stores in Sylvia Park and Otahuhu.
Three women and one man are believed to be involved.
