The chief executive of 2degrees, Eric Hertz, says there is plenty of growth left in the New Zealand market, despite the upstart mobile phone company passing the one million customer mark.
Hertz said New Zealand, despite having market penetration of 120 per cent, had not reached saturation for mobile phone devices.
"It's no longer about the number of people in the country," he said. "It's really about the number of connections."
The advent of smartphones and tablets had already changed consumer behaviour significantly, and would continue to do so as the technology became progressively cheaper.
"In the future, cameras and all kinds of devices are going to have connections to the network," he said. "It's not about four million people, it's about, in the next few years, 15 to 20 million connections that people will be seeking."
