The NZ Transport Agency is advising people to delete a widely distributed spam e-mail message which purports to be from an NZTA staff member and tells recipients to visit a bogus website to collect 'prize money'.
"These emails are not legitimate - they are spam and as such they should be deleted immediately," said NZTA spokesperson Andy Knackstedt.
The NZTA has advised the Department of Internal Affairs and the National Cyber Security Centre of these unauthorised e-mails, and both organisations have added them to their lists of spam alerts.
The NZTA has confirmed that the spam messages have been traced to a single e-mail account which has since been disabled.
The NZTA has reviewed the security of all of the websites used by customers to carry out on-line transactions, and can confirm that the spam e-mails have no connection to the use of these secure payment websites, which remain safe for customers to use.
The NZTA apologises for any concern or inconvenience caused by these spam messages, and urges anyone with questions or concerns to ring our contact centre on 0800 108 809.
