Voter turnout has been slow in the four by-elections around the country.
The percentage of voters was in the mid-teens by Friday afternoon.
Ahead of what is usually an evening rush, turnout in the by-elections is low as politicians fight with Black Friday sales and the 'Late Late Toy Show' for the attention of voters.
Most areas have seen turnout in the low to middle teens.
In Wexford the average turnout was around 15% with a high of 18.8% just outside Gorey
In Cork North-Central, voting was described as very slow: between 8% and 10% by one estimate.
Things are not much better in Dublin Fingal or Dublin Midwest.
The lowest ever turnout for a by election was 27.88% in Dublin South-Central back in 1999.
By-elections
The elections today are to replace the four TDs who were elected to the European Parliament in May.
The last by-election was in 2015 and these are the first in the lifetime of this Dáil.
Many candidates are expecting the turnout in these elections to be low – with some saying they would be surprised if it topped 35%.
The usual election rules apply - with voters asked to bring ID and their voting cards.
Selfies and other photos are not allowed in the polling centres.
Polling stations close at 10.00pm.
It is expected results of the by-elections will be known by Saturday evening.
The new TDs will take their seats in the Dáil for the first time next Tuesday.
