[UPDATE: The problem persisted into the evening for some users, but was resolved overnight.]
Some 2degrees customers can't make voice calls after problems hit the company's landline broadband network earlier today.
One customer told the Herald the problems first hit around 7.15am.
As of midday, the problem persisted, with no estimated time for a fix.
The Herald understands Nelson Marlborough DHB and Christchurch City Council are among those affected.
