“We have also identified less than 100 customers who had a monthly financial statement stolen.”
A Latitude spokesperson said they did not yet have information on how many New Zealanders’ data had been stolen.
It confirmed just over 2000 Kiwibank customers’ data had been stolen when the hack was first announced, but it was unclear whether more customers had been impacted than previously thought.
The company’s Gem Visa card offers interest-free deals at several major retailers, including Harvey Norman, Noel Leeming and Apple online.
The company said records dating back to at least 2005 had also been stolen, approximately 6.1 million records, 94 per cent of which were provided to the company before 2013.
“These records include some but not all of the following personal information: name, address, telephone, date of birth,” Latitude said.
Chief executive Ahmed Fahour said it was hugely disappointing that such a significant number of customers had been affected.
“We are committed to working closely with impacted customers and applicants to minimise the risk and disruption to them, including reimbursing the cost if they choose to replace their ID document,” he said.
“We are also committed to a full review of what has occurred.
“We urge all our customers to be vigilant and on the lookout for suspicious behaviour relating to their accounts.”
