CallPlus chief executive Mark Callander says Orcon's customer support may be repatriated to New Zealand from the Philippines.
Internet provider Orcon outsourced its customer support to Manila, providing work for about 100 Filipinos.
Callander said no decisions had been made on bringing the work back to New Zealand but it was an issue the company would "certainly investigate" after it agreed to buy Orcon last week.
"We have been staunchly proud to be Kiwi-owned and operated and we have proved though Slingshot that you can build a service operation in New Zealand," he said.
Callander said Orcon would remain as a separate brand within the CallPlus group but there would be economies from combining the company's network, including its national backhaul and international capacity, with that of CallPlus and sub-brands Slingshot and Flip.
Orcon employed 150 staff in New Zealand, Callander said, and it was not clear yet whether there would be any redundancies as a result of the takeover.
Orcon's parent holding company, Orcon Holdings, has been in dispute with government-owned telecommunications provider Kordia over a warranty claim. But Callander said the entity that CallPlus had bought was Orcon Limited so it would not be inheriting that dispute and would not be party to any legal action against the state-owned enterprise.
