Mike Hesson has decided to quit as coach of the New Zealand. He stepped down from the post citing family reasons. Hesson believes he isn't fully committed to the job and it is the right to time to make way for someone more deserving.

Under the 43-year-old's tenure since 2012, New Zealand reached the number one spot in the World T20I rankings, and top four in Test and ODI cricket.

According to former Kiwi skipper Brendon McCullum, Hesson was the best New Zealand coach ever. 

"This job requires 100 percent commitment and is all consuming," Hesson told media in Auckland on Thursday.

"I know what’s required over the next 12 months, but if I'm honest, I don't feel I have the capacity to give the job what it deserves.

"NZC, in particular, David White and the board, have given me incredible support, including flexibility and options.

"But the idea of missing a match, a tour or a format, as has been proposed at different times, has never sat well with me."

Hesson gave a special mention to his wife and kids for their support. "I couldn't let this opportunity pass without acknowledging my wife Kate, and our daughters Holly and Charlie, who have sacrificed so much for me over the past six years.

"And I just want to place on record my gratitude to all the players and support staff. I love the team and have great hopes about what they will be able to achieve. I’ll always be a supporter."

New Zealand Cricket chief executive David White said he had tried to persuade Hesson to stay on, but that he understood his reasons for walking away.

"Mike has overseen one of NZC's most successful periods of international cricket, he's more than realized the potential we saw in him back in 2012 and has grown into one of the most respected coaches on the international circuit," he said.

 Hesson's resignation takes effect from July 31.
