Kiwi car rental company Transfercar has been hacked and its customer data compromised, according to the business.
Transfercar customers were sent an email last week alerting them to the breach which occurred on June 6.
"I am sorry to tell you that Transfercar has been the victim of a cyber security incident," the business said.
"The facility where we store our customer records has been compromised."
"The only information that relates to you that could possibly have been accessed by hackers would be your contact details that we pass to the rental operators when you made a booking," it said.
