India crushed New Zealand by 321 runs in the third and final test in Indore to complete a 3-0 series clean sweep.
Resuming on 18 without loss on day four, the hosts declared their second innings on 216 for 3 to set New Zealand a whopping 475-run victory target.
Virat Kohli and his men returned to bowl out New Zealand for just 153, with spinner Ravi Ashwin claiming 7-59 to go with the six wickets he claimed in the first innings.
Kohli said Ashwin's performance was exceptional.
"He's been a champion. I hope he can keep going through this long home season and keep the team at the top where we are," he said.
Ashwin - who picked up his fourth successive man-of-the-series award - said he felt he has been in peak form.
"I feel really good about myself. I've been bowling really well and my confidence is really sky-high," he said.
"It was a wicket where you had to work hard, be patient and bowl good lines.
"This wicket didn't have a lot of bounce. It was not going to short leg or backward short leg, so I had to get them to drive.
Ross Taylor (32), Martin Guptill (29) and skipper Kane Williamson (27) made starts but could not build substantial partnerships to take the match into the final day.
Black Caps captain Williamson conceded their performance was poor.
"Very disappointing. Going into this match we certainly wanted to put together a far more complete performance, that certainly wasn't the case.
"It wasn't though lack of effort, it was..certainly India are the better side in these three test matches and we need to learn a lot from them and be better for it as a young side, I guess getting exposed to these conditions."
The teams now meet in a five-match one-day series starting on Sunday.
