Blackcaps fast bowler Adam Milne has been ruled out of New Zealand's European Tour with an Achilles injury.
Milne, 30, will now likely only be available for the final two matches against the Netherlands, after pulling up during the team's first net session in Ireland.
Otago seamer Jacob Duffy has been called into the T20 squad, following his impressive spells with the Test and ODI teams.
Coach Shane Jurgensn expressed his sympathy for Milne, but is confident Duffy will help fill the void left by the experienced fast bowler.
"We're naturally disappointed for Adam. He's a great character in any team and I am sure he'll apply his strong will to this next phase of rehabilitation," he said.
"There is still a lot of cricket to come this year including the ICC T20 World Cup in Australia, and Adam is determined to make himself available to be part of that selection picture.
"We're backing Jacob to step up. He's made an exciting start to his white ball international career."
"He's an established performer in our Dream11 Super Smash and showed on T20I debut against Pakistan that he can transfer those skills to international cricket."
The Blackcaps have just one more ODI remaining against Ireland on Friday, before the T20 squad travels to Belfast for the first game on Monday.
New Zealand have already been bolstered by the arrivals of Mark Chapman, Daryl Mitchell, Michael Rippon and Ben Sears to their T20 squad.
All-rounder Jimmy Neesham will be the final player to join the team after playing for Northamptonshire in the current round of the County Championship.
