The new 350-kilometer pipeline will carry up to one million barrels a day, the state-run Oil Projects Company said.
A 305-kilometer gas pipeline to feed pumping stations, tanks and other service installations will be included in the project, it said.
The new line will be built alongside an existing 1.6 million barrel-per-day pipeline, which runs through restive Sunni areas and has been idle since it was badly damaged by militant attacks in 2014.
Iraqi forces drove the Islamic State group from the area earlier this year, but the militants are expected to continue to launch insurgent-style attacks.
Authorities did not provide a timeline for the project, which will be offered under a build-own-operate-transfer scheme.
At least 25 per cent of the project will be owned by Iraqi entities.
Iraqi forces seized the disputed city of Kirkuk from Kurdish forces in October.
The Kurds, who had taken control of Kirkuk and other disputed areas when IS swept into Iraq three years ago, exported oil through their own pipeline to Turkey.
The fields around Kirkuk currently produce around 140,000 barrels a day, all of which goes to refineries, Oil Ministry spokesman Assem Jihad said today.
Oil and other infrastructure suffered widespread damage during the fighting against IS. The costs of the war, along with low oil prices, have taken a heavy toll on Iraq's economy.
