“We’re all really feeling for Ben,” said Stead. “It’s always tough being ruled out of a major event at such a late stage, and it’s especially tough in Ben’s case given it would have been his first major ICC event.
“The timeframes for Ben to be fit to play again meant he would likely miss the majority of the group stage, and given the short nature of the tournament, we felt it was appropriate to bring in a player who is fully fit and ready to go.
“Ben is a player with huge potential and given the short rehabilitation timeframe, we’re sure he’ll be fit and raring to go for the home series against Pakistan back in New Zealand.”
Stead said Duffy was a strong replacement in the squad.
“Jacob showed with his performances in the recent home series against Sri Lanka that he is more than capable at international level.
“He’s been part of the squad for the ODI tri-series so he’s fully acclimatised and he’s got plenty of experience in these conditions and is fit and ready to go.
“He’s another player who will be experiencing his first senior ICC event, so it will be an exciting few weeks ahead for him.”
The Black Caps continue their Champions Trophy preparation with a warm-up fixture against Afghanistan in Karachi on Sunday, before beginning their campaign in the opening match of the tournament against the hosts Pakistan on Wednesday.
