Waipu's infrastructure would also be finished before the end of the year and all of Northpower's work would finish in four years.
The remaining nine towns would be connected by Chorus within six years, and included Ahipara, Kaitaia, Morewa/Kawakawa, Russell, Kaikohe, Kerikeri, Paihia and Taipa Bay/Mangonui.
Mr Guy said UFB would benefit everyone from families to businesses and while the transport infrastructure, such as the Puhoi to Wellsford route was vital, the broadband infrastructure was important to the region.
He said UFB would help transform Northland's economy.
While Northpower already had a schedule of work published, with strict conditions to complete each build in 12 months, Chorus had yet to secure that information and was taking a further three months to finalise details and sub contracts.
Mr Guy said a number of other locations would be included in the next rollout of connectivity, with the tenders for the Rural Broadband Initiative phase 2 (RBI2) and Mobile Black Spot Fund (MBSF) closing in April.
He said that despite private companies owning the vital UFB infrastructure across Northland, both were subject to government contract, with assurances that costs would remain affordable.
The communities with enhanced digital access would see social and economic benefits, said David Wilson, CEO of Northland Inc, the regional economic development agency which coordinated the region's proposal to central government for the UFB extension.
"From Northland Inc's perspective ubiquitous digital access across Northland is fundamental to strengthening and diversifying the regional economy.
"This, combined with the Hawaiki international, submarine cable landing at Mangawhai, will provide international connectivity for a large part of Northland's economy and provide the basis for developing Northland's digital economy further."
He said Northland could attract international investment in the digital sector, local businesses could do businesses better, faster and with international reach and local tech-savvy businesses could develop and locate in Northland.
"Most businesses transact online these days, this is another step towards Northland businesses being able to do that and, given that Whangarei has the highest business take-up of UFB in the country, they are ready."
Northland Chamber of Commerce CEO Tony Collins said UFB1 had changed the online landscape in Whangarei, providing faster, more reliable connections.
He said the success of UFB2 project would be measured by looking at the uptake in the newly connected areas, as well as improved online business activity and digital engagement.
