Due to huge demand for tickets, Take That have added a second date at Croke Park in Dublin.
They will now play on 18 and 19 June.
Around Ireland people queued for tickets overnight.
Due to overwhelming public demand for the tickets, the Ticketmaster website has been crashing in Ireland and the UK.
Promoters recommend that fans keep trying or go to any of the Ticketmaster outlets nationwide.
Speaking to RTÉ News London Editor Brian O'Connell earlier this week, Take That's Gary Barlow said of the tour: "We're going to try and do something for everyone.
"Our message for people who want to come is it's going to be a big stage spectacular. It's going to be a big production show again. We often try to bring theatre to stadiums and that's what we're going to try to do again.
"Hopefully there's something for everyone. If people are coming just to see Rob [Williams] he's going to be doing some stuff on his own. If they're coming to see the four of us we'll be doing stuff on our own and there'll obviously be a section with the five of us."
