"We think there are signs of (prices) stabilising," said Stanners. "Volume growth of 80 to 100 percent (in data demand) eventually finds its way through to what customers pay us. What you are starting to see is that as customers see great value, they start to pay a little bit more on the average."
Operating expenses fell during the year by $25.4 million to $639.3 million, reflecting operational efficiencies, with staff costs falling from $314.9 million to $295.5 million.
However, that fall masked the final year of one-off costs associated with the Telstra integration, with opex expected to fall further next year.
The Testra purchase gave Vodafone NZ fixed line voice and broadband services to add to its mobile offering, which Stanners says remains more profitable than the mobile business operated by its primary competitor, Spark New Zealand.

Telstra had doubled Vodafone's New Zealand staff numbers and added 50 percent to its revenue while not being profitable when it was purchased, said Stanners. The integration had, however, allowed Vodafone to cement itself as number two in the New Zealand market for mobile and fixed line services.
Spark reported this week that it was closing the gap with Vodafone, which had once had around 600,000 more mobile customers than Spark. That difference was now down to 150,000 connections, but Stanners said Vodafone NZ's revenue per mobile customer was superior to Spark's.
"Ours tend to be better value customers," he said. "While it's true that they (Spark) have bridged the customer gap, we have significant leadership in terms of market share. It would take them three to five years to catch us, which of course we won't let them do."
The mobile business was "more profitable" than Vodafone's fixed line services, he said.
Also weighing on the result was an increased in depreciation and amortisation costs at $396.4 million, up from $386.6 million in the previous year. The company has also been in the process of refinancing, which saw some $1.5 billion of principal and accumulated interest owed to Vodafone Group reclassified as current liabilities.
