The report showed a drop-off in the number of about total mobile connections in the 2013 period, due to Telecom shutting off its failed CDMA network, through revenue climbed to $2.44 billion from $2.38 billion in 2012. Data revenues drove the increase, which the commission put down to the rising uptake of smartphones.
The increase in mobile revenue wasn't enough to offset declining revenue fixed line connections, with total telecommunications retail revenue falling to $5.21 billion from $5.25 billion. The number of fixed line connections fell to 1.85 million from 1.88 million in 2012, and revenue fell to $2.77 billion from $2.83 billion.
Still, broadband penetration improved with the number of fixed connections increasing to 1.32 million from 1.24 million.
"Fixed-line connections may be starting to slowly decline as mobile services become more attractive," the report said. "However, the increasing availability of fibre services may be starting to counter any trend to disconnect fixed lines."
Separately, a presentation by telecommunications network operator Chorus, which was carved out of Telecom in 2011, showed the company's roll-out of the ultrafast broadband fibre network was at its maximum pace, passing 238,000 premises as at April 30. The Wellington-based company aims to pass 255,000 premises by the end of June, and has already started work in some areas flagged for the 2015 financial year.
Chorus anticipates the cost to pass per premise will drop off in the 2015 financial year as it moves from priority zones into suburban areas. The company was targeting a cost of $3,100 per premise for the 2014 financial year before any 'pain' or 'gain' share with service companies.
The company has previously forecast the UFB network will cost between $1.7 billion and $1.9 billion, and the rural broadband initiative to be between $280 million and $295 million.
