New Zealand handed out India a hammering in the first T20I, crushing them by 80 runs - India's worst defeat in the shortest format of the game.
India's bowlers were bruised, with Hardik Pandya conceding 51 from his four overs, the most expensive, and Yuzvendra Chahal with 1/35 the least expensive. The earlier biggest loss was against Australia in May, 2010 by 49 runs.
Seifert and Colin Munro blazed away at the top of the innings as New Zealand, looking to bounce back after being outplayed in the recent one-day worldwide series, posted their third highest Twenty20 total of 219.
The second of three T20s comes at a sold-out Eden Park in Auckland on Friday night, and as the team arrived from Wellington on Thursday, Southee said he was glad to have played his part in putting the Black Caps 1-0 up.
"As a team we have always chased down targets and we believe that whatever target is set in front of us we can do it". "We failed to get a good partnership".
Seifert, whose previous best innings in eight T20 internationals was an unbeaten 14 on debut, gave New Zealand a flying start alongside Munro, who fell for 34 off 20. Seifert slammed six sixes and seven fours in his audacious knock which included a switch-hit boundary off Krunal Pandya's left-arm spin.
Shikhar Dhawan blazed away with a quick 29, but five wickets fell for 26 runs in 33 deliveries once he was bowled by Lockie Ferguson.
Tim Southee, who was dropped for the last three ODI's against India, marked his return to the side with three for 17 off his four overs. The home team was earlier routed 4-1 in the five-match One-day global series.
