The government of Prime Minister Youssef Chahed was supported by 167 of the 217 members of parliament on Friday; 22 were against and five abstained, the newspaper reported on Saturday.
"In order to face our problems, we should transfer the national united government from a simple concept into an executable practice, and then into an attitude," Chahed told the parliament members on Friday, as quoted by The Global Times.
Earlier this month, Chahed was appointed to the post of prime minister by Tunisian President Beji Caid Essebsi. The move came after the majority of lawmakers in the Tunisian parliament passed a vote of no confidence in premier Habib Essid, which followed his unwillingness to form a new unity government and push for economic reforms in the North African country.
Essebsi expressed support for a government of national unity in June, saying it would help overcome political disputes and respond to economic challenges and security problems in the country.
Chahed warned on Friday that Tunisia's economic growth might not exceed 1.5 percent in 2016, which would fall short of the 2.5 percent prediction.
