A total of 200,000 customers have moved their Telecom or Vodafone numbers over to the 2degrees network since its launch two years ago.
Eric Hertz, 2degrees chief executive says the milestone coincides with the launch of its new services for businesses.
"The 200,000th customer to port their number to 2degrees is particularly significant given the launch of 2degrees Business in July, because the last thing a business wants to do is change their number and risk losing contact with valuable customers.”
The figures follow the revelation that Vodafone, the country's biggest mobile operator, lost 26,000 customers in the June quarter.
Hertz says mobile numbers now belong to customers, not networks.
“We understand that a customer’s mobile number is part of their identity, and it should be portable, so they can take it with them, whoever they choose as their mobile provider."
The company boasts on its website that porting takes just five minutes of a customer's time—and they'll get $10 of free credit to boot. It has actively marketed portability, which enables users to keep their 021 or 027 prefix.
It will open two new stores in Auckland's CBD on Friday, one at 34 Queen St and one in the Civic building on Wellesley St.
