"The spectrum cost $15 million and had eight years left on the licence," said Sherriff. "Converted to an 18-year term, that amounts to around $33 million for 15MHz paired versus the $66 million in today's reserve."
Adams said that "in setting the reserve price, we have balanced generating a fair return on the sale of the spectrum rights with the significant investment required by mobile network operators to build the 4G network infrastructure" and "the value to New Zealand of having 4G connectivity widely deployed."
While 2 degrees welcomed the government's willingness to take staggered payments for new spectrum over five years, Sherriff said "paying a premium right now - even with terms - for spectrum we can't use for some time, is a challenge for all players but particularly 2degrees as a late entrant."
"We're investing heavily to deliver competition to a market dominated by two players controlling 90 per cent of the industry's revenue. We're still building our network and will deploy 4G next year using the 1800MHZ," he said.
"Affordable 700MHZ spectrum was crucial for future mobile competition. We hope the government keeps sustainable competition in mind throughout this process," Sherriff said.
Meanwhile, Telecom welcomed the auction but warned that, at this stage, there were no handsets available from international manufacturers to operate on the 700MHz band.
"Current indications are that suitable devices will start becoming available in mid to late calendar 2014 at the earliest," the company said.
