Ireland skipper Andrew Balbirnie won the toss and elected to field against New Zealand as they look to hurt the Black Caps' semi-finals chances at the ICC Twenty20 World Cup on Friday.
Kane Williamson's New Zealand top the Group 1 table with five points and a win in Adelaide will seal their final-four place. They remain unchanged from the previous loss to England.
Defending champions Australia, who play the next match of the double header at the venue against Afghanistan, and England are also on five points.
Ireland, who took down two-time champions the West Indies in round one and then shocked England in a rain-hit Super 12 clash, are already out of the semis race but want to finish the tournament on a high.
They play the same team which lost to Australia in Brisbane.
