Telecom apologised to affected customers for the inconvenience, she said.
The outages have prompted a backlash from some customers on Twitter.
Hayden Shaw noted the issue as he mocked Telecom's planned name change to Spark: "Hi @telecomnz can you `spark' my broadband connection back to life now please?''
Kirsty Hughes said her home broadband was down this morning. "I've had to come into work to use the internet!''
Another Twitter user said her parents in Whakatane had waited on the helpline for an hour last night, but the Telecom website at the time said there were no issues.
