2degrees has given 60 minutes of free calling to its customers who are currently in Japan or have made calls to Japan over the past 30 days.

The credit was added to customers’ accounts this morning.

Chief Executive Eric Hertz said, "We know that many of our customers are in Japan right now, or have friends, family and whanau in Japan right now.  We hope that this will help them to keep in touch with loved ones during this difficult time.”

2degrees customers who have roamed on a network in Japan over the past four days have automatically been given $50 credit.

Update: Telecom has sent word that its landline customers who called Japan between 12pm Fri 11 March to midnight Sunday will have calls credited back in next bill.
