The Government hopes this stage of the build will be finished by 2015.
Chorus' communications manager, Robin Kelly, said there would be an opportunity for some homes to be connected during this first part of the project.
All urban-zoned homes across the city will have a fibre connection by the end of 2019.
Crown Fibre said details of what areas would get fibre first would be released in the coming weeks.
The deputy chairman of Auckland Council's Economic Forum, Cameron Brewer, said experts were recommending the North Shore and Rodney should get a connection first.
"[The Bureau of Economic Research] identified 12 areas, which are largely in the former North Shore City area and Rodney District, as places of economic priority and places that would benefit the greatest," Brewer said. The council would identify where it would like fibre to go in its 30-year plan, he said.
The draft of the plan is due out next month and will be finalised early next year.
"This is a Government-led and funded rollout and the Government has its own priorities ... but it is keen for us to have some input at a local level, particularly around residential rollout," he said.
Crown Fibre also indicated this week that the Wellington portion of the project would begin in the fourth quarter of 2011.
The fibre rollout has already begun in Whangarei and Hamilton and is due to begin in the next few weeks in Tauranga and Wanganui.
