Henry Nicholls was the surprise inclusion in the Black Caps squad named for the World Twenty20 in March.
The Cantabrian batsman has been picked as the back-up wicket-keeper, meaning there's no room for Tom Latham.
"Henry has shown his talent and versatility with the bat this summer and has also been used as a wicket-keeper for New Zealand A," said Hesson.
"With the Indian conditions in mind, the plan has always been to take three front-line spinners and all three bring something different."
Currently injured trio Tim Southee, Ross Taylor and Mitchell McClenaghan have all been named and are expected to be fit for the tournament.
Elsewhere, there is three spinners in the squad, with Ish Sodhi beating out Todd Astle to join Mitch Santner and Nathan McCullum, who will retire after the tournament.
"It's great to have Nathan available again and his experience in the foreign conditions will be invaluable. Both he and Mitch Santner have the ability to bowl in the first six overs, which gives Kane a number of options to work with.
"On top of our four genuine pace bowlers and Corey as all-rounder, Colin and Grant are also options with the ball for us with their change of pace."
New Zealand's first game of the tournament will be against hosts India on March 15.
