Orcon Genius, which went on sale this week, would "shake up" the telecommunications industry and force down phone and internet costs for consumers.
Mr Bartlett estimated it would drop the price of monthly household internet and phone bills by $30 to $40.
While those living in Auckland, Wellington and Christchurch had reaped the benefits of telecommunications competition, places like Otago had not yet seen competition drive down prices.
The device doubled as a wireless modem, creating a complete telecommunications package in a small sleek device. Price packages started at $70 for "oodles" of broadband and phone calls.
"This is the way of the future. Pretty soon, all content will be transferred via your internet connection. With Orcon Genius, you can bin the traditional fixed phone line and make your phone calls over the internet and save money," he said.
People were able to use the handset built into Orcon Genius, or plug their own phones into the unit and make and receive calls just as they always have but over the internet, including keeping their existing phone number.
The company had been working on the product for the past two years, developing it in partnership with iiNet, Australia's second-largest broadband provider.
Much effort had been put into making it operate exactly the same way as people's household phones did now.
