WELLINGTON, New Zealand (AP) — Former Australia coach John Buchanan has resigned as New Zealand's director of cricket, continuing a major shakeup in the sport's management and administration.

While local media blamed the breakdown of his relationship with national coach Mike Hesson, Buchanan said on Friday he is leaving the position after two years for family reasons.

Buchanan's resignation comes only days after national selection manager Kim Littlejohn said he would not reapply for his role.

In less than a year, New Zealand has announced changes of captain, coach, director of cricket, chief selector and board chairman.
