Telecom is again reassuring its customers that the "90 #" telephone scam does not work in New Zealand.
Telecom says the trick appears only to work in the US, and only with customers using a PABX system. It involves a scammer telephoning a customer, claiming to be a telephone service techician who needs to test the line. The customer is asked to dial 90# and hang up - this can then allow the fraudster to make phone calls at the customer's expense.
In a statement, Telecom says it first heard of the scam more than 18 months ago and has since tested its network and commonly used PABX system. Telecom's fraud centre manager Colin Yates says the company has checked with Telstra in Australia "and it seem its doesn't work there either."
In any case, says yates, Telecom never phones customers to ask them to complete tests over the telephone.
"Any customers receiving such calls should call Telecom as soon as possible with any details."
