Wright took over as coach of the national team at the end of 2010 and during that time took them to the semifinals of the World Cup in 2011 and to a historic test win over Australia in Hobart in December. But he's declined an offer to continue in the role, meaning NZC will have to search for a replacement.
"John has been an outstanding servant for cricket in New Zealand over a long time and it is disappointing to lose someone of his calibre,'' NZC chief executive David White said. "We were keen to see him continue his head coach role, however, understand and respect his decision to look for another challenge.
"The fighting performance of the Black Caps at the ICC Cricket World Cup 2011 and again in the test victory over Australia spoke volumes about John as a coach and he can be proud of the way he has advanced the current team.
"We are keen to fill this critical role as soon as possible but are conscious that we need to take the time to find the right candidate who can take us through to the 2015 ICC Cricket World Cup.''
Wright said: "I am grateful to New Zealand Cricket for the opportunity to coach the national team. I had always wanted to coach New Zealand cricketers for New Zealanders and it has been a tremendous privilege for me.
"I appreciate the offer to extend my contract but after much consideration I feel it's the right time to move on and look at other opportunities.''
