Captain Nick Kelly added a brisk 39, while Josh Clarkson provided late impetus with an unbeaten 27.
For Bangladesh, leg-spinner Rishad Hossain was the standout with 2 wickets, while Mahedi Hasan, Shoriful Islam, and Tanzim Hasan Sakib chipped in with a wicket each to keep the visitors in check.
In reply, Bangladesh paced the chase superbly despite a few early setbacks. Towhid Hridoy led the charge with a brilliant unbeaten 51 off 27 balls, anchoring the innings under pressure.
He found strong support from Parvez Hossain Emon, who smashed 28 off just 14 deliveries, and Shamim Hossain, whose explosive 31* off 13 balls sealed the game in style.
Earlier contributions from Saif Hassan (17) and Tanzid Hasan (20) helped set the platform, although New Zealand briefly fought back through Ish Sodhi, who picked up two wickets.
