Shane Bond
Bond, the team's bowling coach, has indicated he will not seek to renew the contract, which runs until the end of the tournament.
New Zealand Cricket head of cricket Lindsay Crocker said his organisation had been anxious to retain Bond's services and had offered him an extension.
"Make no bones about this -- we're very disappointed to be losing Shane," said Crocker.
"He's given great value to the Black Caps programme and we were hopeful of having the benefit of his input over the next few seasons.
"However, we respect his decision and his reasons for making that decision, and wish him well in his endeavours post-world cup."
Crocker said NZC would start advertising for the post-CWC 2015 vacancy immediately.
