"We're in a unique set of circumstances in New Zealand, whereby the Government has deployed effectively a nationwide fibre to the home [network]."
Asked if 2degrees could conceivably sell UFB services to customers, Sherriff replied: "Absolutely."
While it was quite easy for 2degrees to upgrade its network to offer 4G mobile internet, Sherriff said it was difficult to see why users need the speeds from those faster services right now.
He said 4G was in the "planning mix" but that it seemed wasteful for 2degrees to deploy capital to enhance speeds when customers didn't require it.
Both Vodafone and Telecom have or will soon launch 4G services.
Sherriff took over as chief executive of the company after previous boss Eric Hertz died in a plane crash earlier this year.
The pair had been friends for almost 17 years and part of the reason Sherriff took on the job was to continue Hertz' legacy of introducing competition into the country's telecommunications market.
