Just 15 people have applied to run for Renua in the General Election across the nine constituencies for which the party has so far sought potential candidates.
The figure includes the party's three sitting TDs and one senator who are expected to be selected to represent the country's newest political movement.
The party has stated it is targeting 10 Dáil seats after the next election, which is expected early next year.
The 15 include sitting TDs Lucinda Creighton (Dublin South East), Terence Flanagan (Dublin North East) and Billy Timmins (Wicklow) as well as Senator Paul Bradford.
So far only one candidate, childcare advocate Shane Dunphy from Wexford, has been officially selected to contest the General Election for the party.
It comes despite emails being sent to the party's members in Wexford stating it had been "overwhelmed" by the level of interest that had been expressed.
Members received an email last month informing them they could register their interest in being selected as a Renua candidate.
A week later, members received another email telling them the deadline to apply had been extended.
"We have been overwhelmed by the volume of CVs and cover letters received since last Monday's announcement and are sincerely grateful for your keen interest in becoming the Renua Ireland candidate for your constituency," the email said.
"The sheer volume of applications has been such that we have decided to extend the deadline for submissions to this Thursday, May 21."
A party spokesperson confirmed three applications had been received in Wexford. One applicant, a teacher who has emigrated after he could not find employment here, travelled back from Abu Dhabi for his candidacy interview. The party said it was happy with the level of interest expressed so far and the selection of Mr Dunphy.
"Lots of people are interested in running in theory but taking on the big, incumbent parties is a hard and difficult road. We are impressed by those who have applied," a spokesperson said."
