The scoreline blew out in the final quarter as New Zealand rattled in four goals in the last eight minutes.
The last time New Zealand passed eight goals was the 31-0 blowout against Samoa at the Oceania tournament in late 2015, and there was a 12-0 shellacking of Poland a couple of months earlier in Antwerp.
Black Sticks star Stacey Michelsen has had injury issues since returning from last year's Rio Olympics. She put those behind her in grabbing a fine hat-trick and showing some classy touches.
Attacker Sam Harrison snagged two goals with the other three coming from Kirsten Pearce, Maddie Doar and Steph Dickins, the latter two getting their debut international goals.
World No 12 India got goals from Liliana Minz, from a penalty corner in the third quarter and Anupa Barla scored just before New Zealand's late goal burst.
''In the first quarter India probably had the run of most of the play," Black Sticks assistant coach Sean Dancer said.
''We scored our first against run of play. It wasn't a great quarter but to girls credit they certainly stepped it up and scored some good goals."
There are a number of players vying for World League selection. Hands are being put up by players wanting to catch the selectors' eye.
''We're looking at the big picture and trying to give plenty of people opportunities," Dancer said.
''Maddie Doar has certainly had a couple of good games, along with a lot of other girls who are doing a good job at the moment."
There are some niggling injuries in the squad, notably key defender Liz Thompson, while Rose Keddell is battling a virus but no injuries are rated serious.
The third game of the series is at the same venue tomorrow night.
