The Government will retain control of the Seanad despite the loss of two seats in the election thanks to a stronger-than-expected performance by Fianna Fáil.
Labour gained two seats and Sinn Féin won its first ever seat in Seanad Éireann due to a voting pact between the two parties.
The big surprise in the election to the six university seats was the election of newspaper columnist and college lecturer Rónán Mullen, who ousted Brendan Ryan of the Labour Party to take one of the three seats in the National University of Ireland constituency.
In the election to the 43 seats available on the five vocation panels, Fianna Fáil ended up with 22, a loss of two seats; Fine Gael won 14, a loss of one; Labour won six, a gain of two; and Sinn Féin won one.
The Taoiseach will include two Green senators and two Progressive Democrats among his 11 nominees, who are expected to be announced next week.
This will give the Government parties 33 senators, a comfortable working majority in the upper house.
Fianna Fáil was helped by its voting pact with the Greens and the PDs, and it also benefited from Sinn Féin support on some of the panels.
Fine Gael surprisingly lost a seat due to bad vote management, but the party elected a crop of new senators, most of whom will be strong candidates at the next Dáil election.
Among them are Paschal Donohoe in Dublin Central, Nicky McFadden in Westmeath, Paudie Coffey in Waterford and Eugene Regan in Dún Laoghaire.
Labour had a successful Seanad election, increasing its number of seats from four to six due to its deal with Sinn Féin on three of the five vocational panels.
The good news for Labour was marred somewhat by the failure of Mr Ryan to retain his seat in the National University of Ireland constituency.
There was some consolation for Labour in the election of party member Prof Ivana Bacik for Trinity College. While she will not take the party whip, she will retain a close association with the party.
Sinn Féin won its first seat in the Seanad with the election of Pearse Doherty from Donegal South East, widely regarded as one of the rising stars of the party.
