(Telecompaper) New Zealand's Commerce Commission has released its proposal for the method of setting the price of unbundled bitstream access to Chorus'network. The proposal is based on the 'Final Pricing Principle' in the Telecommunications Act. The Commission determined the UBA price in November at NZD 10.92, according to the Act's Initial Pricing Principle, that is, by international benchmarking. The industry has since called for the Commission to reassess that price according to the Final Pricing Principle, by undertaking an engineering model calculation of UBA costs in New Zealand. The Commission proposes to determine the UBA price by modelling the cost of providing the UBA service on Chorus' existing copper network, or in some regions, on 'Rural Broadband Initiative' fixed wireless. The regulator's proposal is now open for public comment until 21 February, and it aims to complete the process for setting wholesale prices by 01 December this year.
