25 - Colin de Grandhomme's 25-ball fifty in the 4th game of the series is the fastest fifty for New Zealand against Pakistan in the ODI format.
Matt Henry was the pick of the New Zealand bowlers, taking 4-53.
This season he has seven wickets at a strike rate of 27 and 128 runs at a strike-rate of 152, including 10 sixes, as part of a Central Districts side which faces Auckland at Eden Park Outer Oval on Wednesday for a place in the domestic T20 final.
The only previous time New Zealand swept a five game ODI series was against the West Indies in 2000 but after easily winning the first four matches, the Black Caps had to battle hard to repeat the feat after a lower order batting collapse left the home side defending a total which Pakistan very almost reached.
Kane Williamson of New Zealand holds the series trophy after winning the game. He's played some poor shots but got a good one this time, a gem from Henry at 140kmh that found the edge to Guptill.
Henry was brought into the side to replace the rested Trent Boult ahead of the T20I series.
He was full and straight, shaping the ball away or nipping off the seam, mixed in with the odd lethal short one.
Martin Guptill scored a century as Pakistan limited New Zealand to a modest 271 for seven in the fifth one-day worldwide (ODI) here on Friday.
Pakistan battled to 5-57 after 17 overs, losing Mohammad Hafeez for six and Sarfraz Ahmed for three before Haris Sohail dug in with Shadab Khan to put on 105 for the sixth wicket. Santner (3-40) was excellent on a pitch that gave him some encouragement.
Henry was making his first global appearance since the Boxing Day ODI against the West Indies, coming in for the rested Trent Boult.
Munro stormed out of the blocks with 34 off 24 deliveries before he was dismissed by Rumman Raees (3-67), while Yamin (1-65) got the wicket of Williamson (22) 12 overs later.
After a frustrating morning, Pakistan's attack enjoyed some late success when they took four wickets for 12 runs.
De Grandhomme got a promotion with eight overs left and his 29 off 21 boosted New Zealand to a handy total.
