Telecom plans to trial fourth generation mobile broadband network technology before the end of this year.
4G networks, also known as LTE or Long Term Evolution, are seen as the future of the mobile phone as they offer super-fast speeds.
They are already being trialled in the United Kingdom and have been rolled out in the United States and parts of Australia.
Telecom says it will progressively adopt 4G network capability and aims to have a trial service operating for selected businesses and customers before the end of the year.
The Ministry of Economic Development is yet to announce detailed plans for the auction of its 700 megahertz spectrum, which will be necessary for 4G.
The spectrum will be freed up by the move to digital television from analogue services, which begins in September this year.
