New Zealand network operator Chorus has sought leave to appeal a High Court judgement over cuts made to copper broadband prices by the commerce commission.
The appeal follows a three-day hearing in the High Court in Wellington.
During the hearing Chorus told the Court the commission had taken a "mechanical approach", rather than evidence-based decision making.
Chorus claimed the commission had therefore erred in law when cutting prices.
The commission had previously told Chorus it could charge only $10.92 per month for copper broadband connections, down from $21.96.
Justice Stephen Kos rejected this argument in a ruling against Chorus on April 8.
Chorus general counsel, Vanessa Oakley,said: “We must continue to use every option available to us in order provide clarification of pricing principles and section 18/18 (2A), which is a critical part of the regulatory regime and affects both current and future industry outcomes,” she said.
“It is important to note that seeking this further guidance does not disturb Chorus’ strong focus on the Final Pricing Principle (FPP) processes underway, which are due to be completed by the Commission by 1 December 2014.”
