The White Ferns outclassed Pakistan to go through the group stage unbeaten in the Women's ICC World T20 at Warner Park, St Kitts.
They now face the West Indies in the semifinals on Saturday.
An economical opening spell by spinner Erin Bermingham and seamer Sian Ruck ensured the White Ferns held a firm grip on the game from the start after Pakistan won the toss and chose to bat.
Strike bowler Nicola Browne then ripped out both openers to initiate a collapse that saw Pakistan reduced to 30 for seven.
Browne snared two more wickets to finish with excellent figures of four for 15 while Kate Broadmore, Lucy Doolan and Sophie Devine chimed in with one apiece.
Tail-ender Sania Khan managed to hit Pakistan's top score of 15 at the end of the innings as they struggled through to 65 for nine.
The White Ferns needed only 8.2 overs to complete the rout but did lose the wickets of Suzie Bates (4), captain Aimee Watkins (15), Sophie Devine (23) and Rachel Priest (2) along the way.
Sara McGlashan hit an aggressive unbeaten 16 off 13 deliveries to seal the win.
Watkins said facing the West Indies would be a challenge.
"They are the kind of team that are so unpredictable at Twenty20, one day they could make 80 all out and another 180 for four so I'm not taking the upcoming fixture lightly.
"Hopefully they've watched today's game and seen what kind of a bowling attack we've got in our side."
