The Department of Foreign Affairs believes all of the Irish people who were stranded in the Machu Picchu area of Peru have now made their way out of the area.
15 Irish citizens were known to be among the thousands of tourists left cut off in the region by torrential rain and mudslides.
It is understood all 15 have made their way out of the area, the majority by helicopter, although a small group hiked.
Five people, including two hikers on the Inca trial, have been killed by the floods and mudslides.
Rescue teams stepped up their efforts yesterday as better weather allowed a flurry of helicopter flights.
Yesterday saw 1,400 people rescued from the jungle-covered areas surrounding the Inca site by midday, the Peruvian Minister for Tourism Martin Perez said.
12 helicopters took advantage of a break from the torrential downpours to run some 93 flights laden with weary tourists from the town of Aguas Calientes at the foot of the ruins.
Authorities said 800 tourists were still stranded, either in or near Machu Picchu or along the Inca Trail, a narrow Andean pathway up to the ruins that takes four days to complete.
The rescue operation resumed at 6am local time (11am Irish time), weather permitting.
Heavy rain and mudslides since Sunday have severed road and rail access between the city of Cusco, the ancient Inca capital, and Aguas Calientes.
US ambassador to Peru Michael McKinley said the US was 'supporting, not managing the rescue, which should take two to three more days to conclude.'
Machu Picchu is one of the most popular tourist destinations in Latin America, attracting more than 400,000 visitors a year.
The 15th-century Inca citadel is located on a high mountain ridge, 70km from Cusco.
Peruvian officials defended the slow pace of the operations, saying they were being hampered by the heaviest rains in 15 years.
The Peruvian government has also sent food aid to the 8,000 residents of Aguas Calientes, cut off by landslides and swollen rivers.
