The figures show the Republican Party, led by Prime Minister Serzh Sarkisian, who is the favored successor to Kocharian, won 65 seats in the 131-seat parliament.
The pro-presidential Prosperous Armenia party placed second with 25 seats.
Opposition parties won 16 seats. The vote is regarded as a test of democracy in the Caucasian country and a dress rehearsal for a presidential contest in early 2008.
Observers from the Organization for Security and Cooperation in Europe (OSCE) called the voting a "clear improvement" that showed "progress" compared with earlier ballots, saying it largely met international standards for democratic elections.
