"I looked at what I have achieved in my time and think that it is the right time to pass the baton on to someone else and explore other opportunities."
Speaking from Hamilton where his side are preparing to take on the Sky City Northern Knights in the Ford Trophy, Hunt said: "I will miss the fantastic team spirit that the Stags have and I'm proud of what has been achieved.
"I also really appreciate the opportunity that CD Cricket has given me."
Central Districts chief executive Hugh Henderson spoke positively of Hunt's contribution in three seasons with the association.
"Alan has made an excellent contribution to CD Cricket, as his results reflect," Henderson said.
"Not only have we had success on the field, but we have also seen the development of a number of our younger players which augers well for the future.
"We are in the process of finalising a new CD-wide cricket plan and want the Stags head coach to be a constant for the next two to three seasons to implement that part of the plan.
"In talking this through with Alan we agreed that this would be too long in the role for him to commit to, and that it was better to make the change now."
The role will be advertised in the coming weeks.
