“We understand Martin’s position,” said NZC chief executive David White. “He’s been a fantastic batsman for us for a long period of time, and we certainly don’t wish to stand in his way as he explores other opportunities.
“Martin’s been a giant of the white ball game, a committed and well-respected member of the Black Caps, and has earned the right to play out his career on his own terms.
“He leaves his contract with our best wishes.”
Guptill is the third Black Caps player to request a release this year, after Trent Boult and Colin de Grandhomme, but White said he was comfortable with the existing contracting and selection system.
“Players such as Martin, Trent and Colin, with long and successful international track-records, inevitably end up with alternative playing options at this stage of their careers, and we respect that.
“It’s just part of the natural ebb and flow of individual careers within team sport.”
Guptill said playing for the Black Caps remained his ultimate goal, as it had been for his entire cricketing career.
However, he also wanted to continue playing cricket at the highest level possible – wherever, and for whoever, that might be.
“Playing for my country has been a massive honour, and I’m grateful to everyone within the Black Caps and NZC for their support,” he said.
“But, equally, I’m realistic enough to understand the need to consider my options in the current circumstances.
“With this release, I’m still available for New Zealand, I have the chance to explore other opportunities, and I also get to spend more time with my family – which is important.”
A replacement to fill Guptill’s central contract vacancy will be named in due course.
