Virat Kohli's sparkling century helped India script a 40-run win against an injury-hit New Zealand to take a 1-0 lead in the five-match series.
Chasing India's challenging score of 277 at the Nehru Stadium, New Zealand were short on experience with skipper Daniel Vettori and explosive opener Brendon McCullum missing out due to back injuries as the visitors were all out for 236 in 45.2 overs.
Stand-in skipper Ross Taylor top-scored for the Kiwis with a fighting 66 from 69 balls studded with three sixes and three boundaries.
At 169 for eight, New Zealand looked to give up easily but Nathan McCullum (35 from 35 balls, 4x4) and Kyle Mills (32 from 28 balls, 2x4, 2x6) produced a 67-run ninth wicket stand to give India some tough time in the middle.
