The White Ferns have lost their eighth straight Twenty20 international against England after a rusty opener to their three-match series in Chelmsford.
Chasing 184 for victory, New Zealand were bowled out for 138 in the 19th over to lose by 47 runs.
New Zealand have now lost 17 of their last 18 Twenty20s against England with their last victory coming in 2015.
With veterans Sophie Devine and Suzie Bates dismissed by the third over what was already a massive challenge became even more daunting for New Zealand. Amy Satterthwaite did her best to right the ship with 43 from 31 balls but when she was caught on the midwicket boundary in the 13th over, New Zealand's chase was effectively over at 82 for six.
Some late hitting by the lower order at least made it somewhat respectable but New Zealand will need to improve remarkably in all aspects if they are to get back in the series.
