Wellington: New Zealand produced an all-round show to dismiss Pakistan cheaply and then came back to win by 7 wickets in Wellington on Monday.
Stand-in captain Tim Southee (3-13) and Central Stags paceman Seth Rance (3-26) starred with the ball as Pakistan were bowled out for just 105 on a tricky pitch.
Player of the match Colin Munro (49*) anchored the awkward chase and with assistance from Tom Bruce (26) and Ross Taylor (22*), the target was run down with 25 balls to spare.
The series moves to Auckland for game two on Thursday, with the series finale at Bay Oval on Sunday, January 29th.
Earlier, Pakistan's batting woes continued as they bundled out for 105.
Only Babar Khan and Hasan Ali, in a 30-run partnership for the eighth wicket, reached double figures.
Babar was the last man out for 41, with two balls remaining in the innings, while Hasan (23) distinguished himself with a huge six to see Pakistan pass their lowest Twenty20 score of 74 set against Australia six years ago.
Before the late charge by Babar and Hasan, Pakistan had again been let down by their recognised batsmen, just as they were when losing all five one-day internationals against New Zealand.
The tourists had hoped the change of format would bring a change of fortune but they were in trouble in the second over when Tim Southee, standing in as captain for the injured Kane Williamson, removed Fakhar Zaman for three.
