Problems continue at YahooXtra
Fresh reports of "questionable activity" from YahooXtra email addresses are being investigated, Telecom says.
This follows an advisory last week that an unknown number of YahooXtra email accounts, and Yahoo email accounts globally, had been "compromised".
The company said on Monday that it believed Yahoo had prevented spam being sent out from the hacked accounts.
But some email users said today that they were receiving spam from YahooXtra addresses, suggesting more accounts may have been hacked.
Yahoo has been blocking customers' accounts once it has found hackers have obtained their usernames and passwords.
It has been asked for, but has not yet provided any reassurances that customers' mail has not been read.
Customers whose accounts have been compromised and blocked have been advised to reset their passwords so they can regain access to email, but the process does not appear to be going smoothly for everyone.
Wellingtonian Lenore Bamfield said she found all the emails she had deleted since 2009 – numbering nearly 3000 – began reappearing in her inbox after she was forced to reset her password. All new emails were appearing twice.
Telecom's customer support staff had been difficult to contact and to understand, she said.
"I am going to get Geeks on Wheels to sort it out; it is worth paying $115 for somebody else to deal with the problem."
