The Gigatown winner will be the first town in the Southern Hemisphere to access a one gigabit per second (1Gbps) internet connection which is tipped to be a major drawcard for business interests looking to set up shop, and a major boost to existing organisations.
The current average New Zealand broadband speed is 10Mbps (Megabytes per second) and this can be increased to 100Mbps by connecting to the new ultrafast broadband (UFB) network Chorus is rolling out.
The winning town would blow even the UFB speed out of the water with connections of up to 1000Mbps (1 gigabyte) available.
Chorus social media specialist Jon Dow said the competition was essentially an advertising campaign for Chorus, the company undertaking the UFB roll-out around New Zealand.
If Dunedin won the gigabit, connections would be available in 2015 at the earliest, although some areas would not be able to access it immediately as they would not become part of the UFB network until 2016.
Any home already connected to the UFB network would be able to discuss switching to the faster connection with their provider immediately.
Those not connected to UFB would need to get a connection to the network before they could use the gigabit internet.
Chorus has already installed UFB fibre in central areas, such as Dunedin City, North Dunedin, Maori Hill, South Dunedin and Roslyn.
It was also available in a few outlying areas, such as St Clair and parts of the Kaikorai Valley and Mosgiel. The plan is to connect the rest of the city by June 2016.
Schools and hospitals would be the first big winners, as they were already connected to the UFB network as a priority, Mr Dow said.
Wholesale prices of 1 gigabit connections for residential users in the winning town would be $37.50. For businesses the wholesale price would be between $50 and $80.
While it was up to individual internet providers to set their prices, the transparency would ensure the low wholesale prices translated into low retail prices, he said.
Mr Dow predicted residents in the winning town would be looking at paying between $75 and $100 per month for the 1-gigabit connections.
Businesses would be the big winners, paying about $80 a month, where they were paying, on average, $500 or $600 now.
Digital Office Gigatown promoter Josh Jenkins said the benefits of winning Gigatown would be significant and wide-reaching.
''It would be a catalytic event that would help Dunedin's economy gain momentum.
Gigabit speeds would provide opportunities for innovation and development in the health, education, design, and niche manufacturing sectors.
This will attract investment into Dunedin and in turn talented people to live and work here because they can work globally and enjoy the great lifestyle.
''It is an amazing opportunity to make Dunedin the most connected city in the southern hemisphere. Surely that would drive innovation and attract businesses to our city,'' he said.
Digital Community Trust chairman and city councillor Chris Staynes predicted winning Gigatown would be a ''game changer'' for Dunedin.
The council's economic development strategy already planned for the city to progress as a knowledge-based economy.
The University of Otago and Otago Polytechnic were the city's largest businesses, he said.
Many other Dunedin businesses worked through the internet, and the engineers and manufacturers were innovators.
The gigabit-speed internet would provide a massive boost in connectivity to all these sectors.
Winning Gigatown would also allow more Dunedin residents access to the benefits of having high-speed internet connections, Cr Staynes said.
