With 71.58 percent of votes counted, Frente de Todos candidate Fernández has 47.36 percent, with Mauricio Macri of Juntos por el Cambio on 41.22 percent.
In third is Robert Lavagna, of Consenso Federal, with 6.14 percent, while left-winger Frente de Izquierda candidate Nicolás Del Caño has 2.06 percent.
News channels quickly began calling the race in Buenos Aires City for Mayor Horacio Rodríguez Laretta after initial results emerged.
