"With a number of our top guys already playing in India, it's helpful to be able to select the squad in two parts. With six spots left, there's an obvious incentive for the players in New Zealand A to perform and put their best foot forward."
Hesson said that while Jimmy Neesham and Neil Broom had missed out on this squad, they still had the opportunity to push their way back into the side for the home summer.
"It will be disappointing for James and Neil, but we've talked through the areas that we'd like to see them work on and if we see development, they'll certainly both come into the reckoning come the home summer.
"Neil was really effective for us batting at three or four last season, but we have quality, established batsmen in those positions and we'd like to see Neil develop his game further to show he has the skills to bat at five.
"Jimmy needs go back and really dominate domestic cricket with both bat and ball. We know Jimmy is a talented player, but we've spoken with him around improving the consistency in all areas of his game."
The team depart for India on 12 October.
