The result in Rawalpindi also ensured India’s semi-final berth in the 50-over tournament as Bangladesh became the other team from Group A to be knocked out.
Both New Zealand and India have two wins from two matches and will now meet in Dubai on Sunday to decide team one and two from the group.
“Feels nice to qualify,” New Zealand skipper Mitchell Santner said after the win. “Knew Bangladesh would be a challenge.”
Pakistan, who won the previous edition of the Champions Trophy in 2017, lost to New Zealand and then India in the first International Cricket Council (ICC) event they are hosting since the 1996 ODI World Cup.
India refused to tour Pakistan due to political reasons and instead are playing all their matches in Dubai, which will host the final if the Asian giants go the distance.
New Zealand have been the team to beat in this group after they humbled Pakistan by 60 runs in the tournament opener.
Coming in as firm favourites in their second match, New Zealand elected to field first and spinner Michael Bracewell returned career-best ODI figures of 4-36 to restrict Bangladesh to 236-9.
Chasing 237 for victory, New Zealand slipped to 15-2 and 72-3 before Ravindra and fellow left-hander Tom Latham, who made 55, added 129 for the fourth wicket.
Both were dismissed before the end but New Zealand still achieved the target with 23 balls to spare.
The Black Caps had a disastrous start when pace bowler Taskin Ahmed bowled first-match centurion Will Young for a duck.
Bangladesh’s new pace sensation Nahid Rana took down Kane Williamson caught behind for five with a delivery bowled at 148.8 km/h (92.4 mph).
