Telecom Corp and Vodafone New Zealand, New Zealand's major mobile phone operators, each spent NZ$66 million on three lots of 2x 15MHz spectrum, while new entrant Two Degrees Mobile bought two lots of 2x 10MHz for NZ$44 million, NZ Communications Minister Amy Adams said in a statement.
That left one 2x 5MHz block of spectrum, which the government expects to figure out what to do with in the coming weeks. The government can either let bidders compete for the remaining spectrum or retain the unsold lot and allocate it at a later date.
"Overall, this is a successful outcome for the auction that bodes well for the future of competitive fourth-generation mobile services in New Zealand," Adams said.
"While 2degrees has bid for slightly less spectrum than Telecom and Vodafone, internationally, we have seen that 2x 10MHz is sufficient to run a viable 4G network and provide much faster data speeds to mobile customers."
The government put a minimum reserve price of NZ$198 million for the spectrum, something that 2degrees said was a premium to the NZ$157 million spent clearing the radio waves in the switchover of analogue television to digital, and the NZ$119 million valuation attributed to the spectrum by the Treasury.
While some 4G capability is already available on higher MHz spectrum, the 700MHz range is especially well suited to pushing fast mobile broadband into rural areas because it requires fewer repeater stations to achieve coverage.
As part of the auction's conditions, the mobile phone operators will have to upgrade existing rural cell sites to 4G capability within five years, and continue to expand their coverage. That's to ensure that at least 90 percent of the country has access to a 4G network within five years.
