Black Caps seamer Tim Southee has been ruled out of the first test against the West Indies, starting on Friday at the Basin Reserve.
The veteran fast bowler is expecting the birth of his child any day now.
Lockie Ferguson joined the squad earlier this week as a precaution, and will battle with Matt Henry for the third pace bowling spot alongside Trent Boult and Neil Wagner.
Coach Mike Hesson said they're gutted to lose Southee, but there's more to life than cricket.
"He's staying at home, and we're very supportive of that so obviously we're family first in this priority. We had a timeline and it hasn't quite worked out."
Mike Hesson says they'll make a call on Ferguson or Henry's inclusion in the XI at training tomorrow.
Fast-medium Henry has taken 22 wickets at an average of 48.5 while Ferguson is an exciting prospect with his pace. Ferguson also took seven wickets against the West Indies in a warm-up match.
Hesson said the decision would be tough as both players were performing well.
"It's nice to have a couple of very good options - obviously Henry did very well in the last Test match he played against South Africa and Lockie is probably bowling as well as he ever has.
"It just depends what we want to go with - whether we want to go with extra pace or whether we think it might nip around a bit and we want someone with Matt's control," Hesson said.
