Zanaco came from behind to beat Harare City of Zimbabwe 3-1 to advance to the second round of the 2016 CAF Confederation Cup.
Zanaco qualified 5-2 on aggregate after picking up a 2-1 first round, first leg win away in Harare on March 12.
However, Zanaco were given an early fright at Nkoloma Stadium in Lusaka on Sunday when Honey Chimutimuzeve put the visitors ahead in the 8th minute.
Zanaco captain Ziyo Tembo equalized with a header the 36th minute to score his first of two goals on the day to see the two sides go 1-1 into halftime.
Ziyo completed his brace in the 77th minute with another header before Davey Daka finished off a cross from Aubrey Funga in the 87th minute.
Zanaco will host Stade Gabesien of Tunisia in the first leg of their second round tie after the latter drew 0-0 away to AS Kaloum in Conakry on Saturday to advance 2-1 on aggregate.
