The Korean economy is widely believed to be moving into a firm but moderate recovery phase.
It grew 2.8 percent last year from the previous year rebounding for the first time in three years.
The Bank of Korea says the rise in the nation's gross domestic product came largely from rising exports, private consumption and construction investment.
Construction investment, in particular, rose nearly 7 percent last year, compared to a 2 percent drop in 2012.
The yearly growth was earlier forecast by the government and the central bank.
The recovery follows a zero.9 percent growth in the October to December period last year compared to the third quarter when it grew 1.1 percent.
