Kerikeri is among 35 towns already identified as a strong contender for inclusion in any UFB extension, with Kaitaia, Kaikohe, and Dargaville.
Mr Stuart said the team was preparing submissions which could provide UFB or RBI access to 80 per cent of the Northland population, in line with Government targets nationally.
About 50 per cent of Northlanders live rurally, compared with 14 per cent nationally.
The widely dispersed population makes UFB costs higher per person, but improved RBI cellphone and wireless services could provide a cost-effective alternative.
"By the end of this month we will have a plan in place to have Northland strongly represented when funds are allocated nationally," Mr Stuart said.
The first phase of UFB is ahead of schedule with 46 per cent of the build complete and 618,000 end users able to connect to the network nationally.
The Northland build was the first to be completed, in May last year, and more than 21,000 businesses and households are able to access the network.
In June last year 9.4 per cent of Whangarei end users with access to fibre had taken up a UFB service, increasing to 17.6 per cent by March 31 this year.
On June 30 last year 96 per cent of state and state-integrated schools in Northland had access to fibre.
All rural public hospitals and integrated family health centres will have access to fibre by the end of 2015. RBI fixed-line upgrades were 76 per cent complete in Northland on June 30 last year.
About 21,000 households and premises have access to wireless broadband service, and about 12,500 to new or improved fixed line broadband.
