NET RESULT: Shane Hobson, left, of Ultrafast Fibre, and Lightwire's Murray Pearson are bringing ultrafast broadband to Hamilton.

Hamilton internet service provider Lightwire will offer the city ultrafast broadband with no data caps from April 1.

The company, spun out of Waikato University in 2006, is the first ISP to sign an agreement with Ultrafast Fibre, which is constructing an ultrafast broadband network in the upper North Island.

Lightwire general manager Murray Pearson said the company would be able to offer the service to Hamilton businesses from April 1 but its prime market would be the residential market, where connections would be available from July 1.

"They are not going to have a data cap associated with them," Mr Pearson said.

It is too early to announce pricing on the new network but it will be worked out in coming weeks.

Lightwire already offers free wi-fi in Hamilton's central business district, as well as wi-fi at Waikato University, and has provided broadband to businesses on the Velocity Network since 2007.

Ultrafast Fibre chief executive Maxine Elliott said the deal with Lightwire was one of many in the pipeline. "This is a signal to the public that this much-anticipated technology is literally days away from being reality."

Ultrafast Fibre is expected to finish building its upper North Island ultrafast broadband network in 2016.
