The NYCI is is calling on young people to ensure they cast their vote
New figures show an extra 30,185 people have been added to the supplementary register to vote on Friday.
The National Youth Council of Ireland (NYCI) has welcomed the numbers, and is calling on young people to ensure they cast their vote.
The NYCI is the representative body for youth organisations - with 40,000 volunteers working with over 380,000 young people nationwide.
James Doorley, NYCI deputy director explained: "The figures from the Department of the Environment indicate that 30,185 people added their names to the supplementary register before the February 9th deadline, which is to be welcomed".
"Now, however, the focus must turn to getting out the vote. NYCI is encouraging 18 to 25-year-olds in particular to make sure they make their voices heard tomorrow, Friday the 26th of February," Mr Doorley added.
Polling stations are open between 7.00am and 10.00pm tomorrow.
Voters should bring their polling card they received by post, as well as some other form of identification - passport, driving licence - with them.
For those who did not receive a polling card, it is important they bring other ID to the polling station.
The Youth Council is also making instructions available to first-time voters on its website.
