The Blackcaps have crashed to their largest Twenty20 defeat, beaten by 168 runs in the third and deciding match against India at Ahmedabad.
An unbeaten 126 runs from opener Shubman Gill set the platform for India to score 234/4 in their 20 overs, before New Zealand folded for only 66.
While the margin is New Zealand's biggest in the shortest format, going down by 168 runs represents the largest loss between two test-playing nations, but it is only the eighth biggest in the history of the game.
The Blackcaps' previous record defeat came against Pakistan at Christchurch in 2010, losing by 103 runs.
The biggest defeat in the history of the game still belongs to Turkey, who were beaten by 257 runs by Czech Republic in 2019.
After winning the toss and opting to bat first, India were rocked, when Michael Bracewell trapped opener Ishan Kishan with his second ball to leave the hosts 7/1.
But adding partnerships of 80 with Rahul Tripathi (44) and 103 with captain Hardik Pandya (30), Gill reached his maiden international T20 century, taking 35 balls to pass 50 and 54 balls to reach triple figures.
Gill's 126 not out also made him the 21st player to score a century in all three forms of the game - including a double-century in India's 3-0 one-day series win over the Blackcaps last month.
And while the Blackcaps were able to hand a first international cap to left-arm fast bowler Ben Lister, the 27-year-old had a night to forget with 0/42 in his four-over spell.
Daryl Mitchell finished as the pick of the NZ attack, albeit with figures of 1/6 from his solitary over, while Bracewell had 1/8 after a one-over spell of his own.
And despite the all-rounders' success, only captain Mitchell Santner (0/37) conceded less than 10 an over among the frontline bowlers.
Chasing 235 to take the series, the Blackcaps again floundered with the bat, with only Daryl Mitchell (35) and captain Mitchell Santner (13) scoring in double figures.
India's new-ball blitz of Pandy (4/16), Arshdeep Singh (2/16) and Umran Malik (2/9) left the Blackcaps batting order in tatters, as New Zealand lost their first five wickets inside the powerplay.
From there, the Blackcaps could only bat out 12.1 overs, before Mitchell became the final wicket to fall, out to Malik for his innings-high score, and seeing the Blackcaps lose the series 2-1.
New Zealand won't have long to dwell on defeat, quickly returning home to prepare for a two-test series against Brendon McCullum's England, beginning at Mt Maunganui's Bay Oval on February 16.
India 234/4 (Gill 126 not out, Tripathi 44; Mitchell 1/6, Bracewell 1/8) New Zealand 66 (Mitchell 35, Santner 13; Pandya 4/16, Malik 2/9)
India win by 168 runs
