Troy Parrott and Lee O'Connor will make their Republic of Ireland debuts against New Zealand after Mick McCarthy named his team a day before the match.
Parrott, 17, will earn his first cap after impressing for the Under-21 side with three goals in as many games.
Celtic defender O'Connor will also feature for the senior side for the first time.
Shamrock Rovers' Jack Byrne, who won his first cap as a substitute against Bulgaria in September, will also start.
The friendly against New Zealand comes four days before the Republic take on Denmark in a crucial Euro 2020 qualifier in Dublin.
"Lee O'Connor will play, the younger lads will play. Troy Parrott will start and Jack Byrne will start," said McCarthy.
Highly-rated Parrott, who has scored three times and picked up a red card in three appearances for Ireland's Under-21s in their European Championships qualifying campaign, has made one competitive appearance for Tottenham Hotspur.
"He's a bright, very intelligent footballer that's very good with the ball at his feet. He did some really good things yesterday," added McCarthy.
"I think he found it tough enough, it was a pretty hard session, but he enjoyed it. He is very capable, there's no doubt about that."
Manchester United goalkeeper Kieran O'Hara, currently on loan at Burton Albion, will also start for the first time.
The 23-year-old made his debut in September's friendly win over Bulgaria in which he came on as a substitute, replacing Mark Travers.
