The Commerce Commission says it will look into a transtasman cable planned by a consortium of telcos for potential competition issues.
Telecom, Telstra and Vodafone announced a memorandum of understanding yesterday for a new link between New Zealand and Australia called the Tasman Global Access.
If the project goes ahead it would be New Zealand's second international connection, running alongside the Southern Cross Cable system, which Telecom has a 50 per cent interest in and which connects to Australia and the United States.
It is estimated the project will cost less than US$60 million and planned to be completed by the end of 2014 if launched.
Slingshot chief executive Mark Callander said yesterday that the cable would create "an unlevel playing field" and that it could present competition issues.
