With four wickets in hand, Pakistan required 150 runs to win at a required rate of 7.56 per over. Any chance of victory was minimal, but Fakhar looked comfortable against the cunning of Boult and Southee, the pace of Lockie Ferguson, and the flight of Mitchell Santner and Todd Astle.
He played the first of his 10 ODIs against South Africa at the Champions Trophy in June.
By tournament's end Fakhar was man-of-the-match in the final, making 114 off 106 balls as Pakistan trounced India by 180 runs.
The left-hander averages 53.55 and makes his ODI runs at almost a run a ball. He had not been in a losing ODI team until yesterday.
Another variable can be added to Tuesday's equation. Pakistan return to Saxton Oval, the venue they started their tour on Wednesday against a New Zealand XI.
They were sent in and made 341 for nine. Fakhar top scored, retiring on 106 off 84 balls after spending more than two hours familiarising himself with the conditions.
New Zealand must plan accordingly.
