The lines company Chorus is able to withdraw copper in areas that already have fibre from September, and Spark had been removing public switched telephone network (PSTN) connections since last year. This had prompted plenty of advertising from the telcos, offering new and expanded services, as they try to retain customers and attract new ones. "We have examples of people being told they need to move now because Chorus and Spark are in the process of withdrawing their copper or PSTN service when withdrawal isn't even scheduled yet, and marketing materials are making claims about the performance of alternative technologies that don't reflect real world performance," Telecommunications Commissioner Tristan Gilbertson said.
