However, New Zealand did well to hold on to a 15-run lead that saw them complete a 5-0 series victory.
Fellow Stags new-ball bowler Seth Rance also returns to the Black Caps set-up after featuring in two of the three recent T20s against the West Indies, the 30-year-old joining the squad early in time for the fifth and final ODI against Pakistan in Wellington on Friday.
New Zealand managed 66 runs in the final 10 overs and lost five wickets as they went on to post 271 for seven in the 50 overs.
Pakistan batsman Babar Azam's sorry tour continues as New Zealand's Matt Henry strikes and Martin Guptill catches.
Opener Martin Guptill raised his 13th ODi century, 12 innings since his previous ton against South Africa last March.
Pakistan were all out for 256 with one over remaining.
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. There hasn't been that big 300 score yet, we've had to do a lot of hard graft with the bat and it proves that those partnerships we've been able to create have actually got us through to some good match-winning totals.
After scoring 100 off 126 balls, Martin Guptill became the second New Zealand batsman to score ODI centuries against all nine major test-playing nations.
Having witnessed Pakistan's performance in New Zealand by now, it would be hard for someone to believe that this team won the ICC Champions Trophy 2017 just a few months ago, and that also in England.
Henry was brought into the side to replace the rested Trent Boult ahead of the T20I series. Henry pinned dangerman Fakhar Zaman on the helmet and removed him to a rash drive soon afterwards, and ended his opening five-over spell with 3-11.
Wellington turned on a stunning day for the fifth ODI against Pakistan, the Basin Reserve's final worldwide match of the home season.
Haris Sohail (63) and Shadab Khan (54) were the only two players to provide their side with some resistance with their blistering half-centuries. Santner (3-40) was excellent on a pitch that gave him some encouragement.
Munro racked up 34 from 24 balls to get the Black Caps out of the blocks before edging to Mohammad Nawaz.
