Telecom and Chorus are in their first big squabble since they split up, with the phone and internet company complaining to regulators over its former network-arm's proposed changes to wholesale broadband services.
The Commerce Commission said this morning it is investigating a Telecom complaint that Chorus' proposed changes could breach the Telecommunications Act.
The complaint was contained in a submission from Telecom on Chorus' proposed new broadband services. These new services - called Boost HD and Boost VDSL - are designed to compete with a regulated unbundled bitstream access service (UBA) which Chorus provides.
UBA is a service allowing internet retailers to provide broadband to customers over Chorus' copper network without needing to have their own equipment in a telephone exchange. The commission sets the terms of this service and its price.
Cuts to the price, due to come into effect in December, caused a raging brouhaha in the telecommunications industry last year.
