After the retirement of Brendon McCullum, the post of the Test captain remains vacant but Hesson is not in a rush to make an announcement and wants to focus only on the upcoming mega-event.
"I don't think that's fair on Kane (Williamson),” Hesson told Radio Sport New Zealand.
“It's something we won't look at until after the T20.
“I think the focus has very much been Brendon (McCullum) going out.”
Kane Williamson has been handed the responsibility of leading the Black Caps in the shortest format of the game and is the favourite to take over in the other formats of the game as well.
New Zealand will play their next Test in the month of July and Hesson stated that the players are also not keen to discuss the appointment of the Test captain at this stage.
“All the players are very keen not to get involved in a captaincy debate.
“The main problem with captaincy is people get into a debate and it becomes one person against another, which is certainly not how this team operates.”
New Zealand will play two warm-up games against Sri Lanka and England in Mumbai on 10th and 12th March before embarking on their ICC World T20 campaign with a game against India on 15th March in Nagpur.
