IMO, they will go with 3 pacers and one spinner (plus Ravindra Jadeja, the spin-bowling all rounder). Going with two full-time spinners in addition to Jadeja sounds too much for me. Kiwi batsmen are not very comfortable against the spinners, but then we can't expect spin-friendly surfaces in New Zealand. So 3+1+1 would be a good combination as far as I am concerned.
The pitch I believe would be fast bowler friendly and NZ have good fast paced bowlers then the spinners . So they would like to go with past faces pitch which may trouble Indian batsman more than spinners , as India can play well against spinners. India would also go with 1 full time spinner and then Jadeja would be another option who can bat as well .
