John Wright has opted to announce his resignation as New Zealand coach after failing to see eye-to-eye with director of coaching John Buchanan.

Wright's current contract is due to expire after the tour to the West Indies - with New Zealand Cricket chief executive David White having offered the former opener a new deal.

However Wright claims differences of opinion with Buchanan were a key factor in his decision to turn down the extension.

"I think he's probably in a better position to do that," Wright said. "We're probably not that different, we just see things a little differently.

"As I explained earlier, the planning systems that John wants to implement are probably suited to another head coach. I think it's just a difference of style. We see things very differently. I wish him and everyone else success.

"I never really envisaged going through to the 2015 Cricket World Cup, so the change has to be made at some stage.

"During the review process with the current cricket director, we both agreed the planning systems that he (Buchanan) wants to implement don't complement the style and the way I coach, so that was another factor.

"It's part of sport. I've enjoyed the opportunity to coach the New Zealand cricket team."

During his tenure, Wright led New Zealand to the semi-finals of the ICC World Cup as well as a first Test success in Australia for 26 years.

And White hailed the impact Wright has had on the side.
