Both the SDLP and Sinn Fein were hopeful of taking a third seat in South Down after boundary changes increased the nationalist population there.
While the DUP's Jim Wells looks set to get over the line, with 5,200 first preferences, it remains to be seen if the UUP's deputy leader John McCallister will have a fight for the final seat in the six-seater constituency. The quota was 5,961 votes.
In the South Antrim constituency, two DUP men and a leading figure in Sinn Fein celebrated side by side as they were elected on the first count.

David Ford was just 41 votes short of the quota, but was later elected on the second count.
Paul Girvan of the DUP topped the poll and Mitchel McLaughlin of Sinn Fein was second in the count, 55 votes ahead of the DUP's Trevor Clarke.
