Chairman Tuwhakairiora Williams said the intention was to license Maori TV for the whole of the spectrum block but MTS may not need all of the frequency.
"It could well be on the cards that any spare capacity that [for] iwi/ Maori who have serious intent with regard to television broadcasting that an accommodation could be made for that purpose as well. But that will be at the behest of Maori Television," Mr Williams said.
Asked if the channels could be used for non-reo revitalisation purposes, for example a golfing or shopping channel, Mr Williams said that too was a possibility but any revenue would be pumped back into Maori TV to support language revitalisation.
Mr Jones said Maori Affairs Minister Pita Sharples had been unable to secure improved funding for iwi radio or 4G rights.
He doubted Dr Sharples would have any more luck pushing for new cash for iwi stations.
"My fear is if the spectrum ... is atomised then it will feed an appetite that everyone can have their own channel like seven migratory waka. That's fine in theory but where will the putea [funds] come from?"
Maori Television chief executive Jim Mather said the costs could be too high for iwi to get into the industry. If a tribe did set up as a broadcaster he conceded it would be "potentially" cannibalistic. Both would vie for funding and audience.
What would occur with the spectrum was still being worked through, Mr Mather said.
"Maori Television is still analysing business case scenarios to identify the commercial feasibility of converting the spectrum into a television multiplex platform from which to broadcast a range of channels. Should this threshold be fulfilled, there is still the issue of any iwi wanting to commit resources to television services."
In a statement Dr Sharples did not address Mr Jones' criticisms around funding. Asked if iwi stations would receive government funding he said: "We have not done any work to investigate the provision of government funding for iwi television."
