On a day dominated by the openers, New Zealand piled further misery on Pakistan to become the first side to secure a semifinal spot in the 2016 World T20.
With Tuesday's 22-run win over Pakistan, Kiwis,who already defeated India and Australia in the last two matches, made sure of a last-4 spot.
On the other hand Pakistan's chances suffered a major blow. After a disappointing defeat to India in the last match, Pakistan were unable to build on the openers solid platform here on Tuesday.
In the sixth over, Pakistan were 65 for no loss, but poor shot execution from then on resulted in their downfall. As a result of which, now Pakistan have to rely on other team's results to qualify from the Group 2.
After Kiwis opener Martin Guptill scored a majestic 80 off 48 balls, it was Sharjeel Khan's time to return the favour.
Initially, Sharjeel got lucky in the second over when his shot in the deep was not gathered by Guptill and it went for a four.
The 26-year-old made the most of it with a great set of stroke play to score runs at a regular interval. Such was the speed at which he scored, Pakistan reached the 50 mark in just four overs after Sharjeel struck a six of Mitchell McClenaghan.
Overall Men in Green reached 50 off 24 balls in just 17 minutes. Most of the runs were scored by Sharjeel with 42 from 19 balls.
However, his blistering cameo came to an end in the sixth over. Sharjeel mistimed a Adam Milne shot which went straight into the air and this time Guptill made no mistake in gathering the ball. At that stage Pakistan were 65/1.
Santner then handed another blow to their run chase as he picked up the second wicket of Khalid latif, who was a late replacement for not fully fit Mohammad Hafeez, soon after. Then, Shehzad, after playing a patient 30 from 32 balls, threw away his wicket when Men in Green were 96.
On came Shahid Afridi and gave the supporters just what they were expecting with a nine-ball 19 runs, including two fours and a six.
However, he was neither able to stay on to finish the job as Corey Anderson's brilliant catch in the deep from Ish Sodhi's bowling turned the tide firmly in the Black Caps favour.
Pakistan were 123/4 at 15.1 overs, needing another 58 runs from the final 29 balls. It looked a difficult task with Afridi not at the crease.
New Zealand bowled cleverly after that to complete the formality as Pakistan were unable to come up with a late flurry to finish their innings at 158/5.
Milne with 2/26 and Santner with 2/29 were the main stars in New Zealand's bowling department. Earlier, the Kiwis decision to bat first paid off .
The opening duo, mainly led by man-of-the match Guptil, were on fire. They reached their fifty partnership in no time.
With a six from Guptill of Mohammad Sami in the sixth over, the Kiwis reached fifty runs. It was the eight fifty plus partnership between Guptill and Williamson in the last 10 T20Is they opened together. After, Williamson (17-runs off 21 balls) and Colin Munro threw away their wicket in quick succession.
But, Corey Anderson and the settled Guptill steadied the ship as New Zealand reached 100 runs in just 12 overs. In doing so Guptill also reached his half century from only 33 balls.
With a four from Guptill in the fifteenth over of Sami, the duo quickly raised on to a half century partnership for the third wicket in just 32 balls.
But Sami had the final laugh as Guptill nicked the ball on to bring an end to his brilliant knock of 80 from just 48 balls, which included 10 fours and three sixes.
However, Ross Taylor's 36 off 23 balls, including 16 runs off the last over from Amir, helped the Black Caps reach a challenging 180/5. Except for Sami's disciplined 2/23 runs, rest of the Pakistan bowlers struggled to pick the lines. Imad Wasim, who came in place of Wahab Riaz, was economical with 0/26 runs.

New Zealand: 180/5 (Guptill 80, Sami 2/23) beat Pakistan: 158/5 (Sharjeel 47, Milne 2/26, Santner 2/29) by 22 runs.
