"They've consistently been fairly aggressive as the third challenger and that's kind of their role in the market, and they've had a few wins on the business side."
There was still a perception that the telco was a relatively minor player, but Wise pointed out that it now had more than 97 per cent coverage.
"They're certainly a credible third player and are continuing to see growth, which is good for the market."
2degrees chief executive Stewart Sherriff said the company's post-paid mobile customer base grew by 19 per cent, which the company hoped would increase further this year and raise the average revenue per user.
"Last year was a turning point for 2degrees. Total revenue grew as average customer revenues increased, while network costs reduced as we completed a mobile network extension programme," Sherriff said.
"It was also the first full year of 2degrees broadband, with customer numbers growing more than 100 per cent as our full-service bundle gained traction in the consumer market and our Telecommunications as a Service (Taas) offering attracted large government organisations such as Ministry for Primary Industries."
Sherriff said 2degrees was maturing as a company and its schemes such as "data clock", which offers time-based data for prepay customers, and New Zealand's first unlimited mobile data plan, were proving attractive.
"What started as a prepay mobile price play has become so much more, with national mobile and broadband networks serving all market segments," he said.
The biggest opportunities for growth in the year ahead were in the fixed broadband market, as well as post-paid mobile services.
2degrees' mobile market share on a subscription basis was 23 per cent, Sherriff said.
Forsyth Barr senior analyst Blair Galpin said 2degrees was an ongoing success story.
"It's fair to say they've been very prominent and influential already, and so effectively moving from loss-making to profit-making doesn't change that. What it does give is a positive message to shareholders," Galpin said.
"Compared to the other telcos the profit's quite a small profit and obviously they've been investing quite a lot as well. But a profit's a profit and effectively they're on the right path. They'll obviously be wanting to grow even further from here."
