Telecom New Zealand announced that it will continue to rapidly expand its 4G network across the country, voxy.co.nz reports.

The operator has announced that it will be bringing 4G technology to Dunedin, Rotorua, Blenheim and Nelson by September 2014. This follows on from the weekend launch of fast mobile technology in Rangiora, Rolleston and Lincoln.

Telecom Retail CEO Chris Quin says more than a hundred additional 4G sites will go live before the end of the year.

Telecom recently revealed over 60 percent of its customer base owns a smartphone, and the average monthly data use for mobile customers on both 3G and 4G has grown by 52 percent over the past year.
