Ross Taylor dropped Pakistan skipper Mohammad Hafeez on 0, off the first over, who went on to score 43 off 38 balls.
Moreover, Rob Nicol also dropped Nasir Jamshed on 34, who went on to score 56 off 35 balls, which included 4 sixes and 2 boundaries.
The duo added 76 runs for the second wicket which actually cost New Zealand the match. Had they taken those catches, Pakistan wouldn't have scored heavily at the start of the innings, and Kiwis could have played without pressure.
Moreover, the dropped catch off the first over, brought the morale down, as Kiwis looked out of sorts, throughout especially in the first 10 overs.
"We probably leaked a few too many runs in that first 10 overs," the Sydney Morning Herald quoted Taylor, as saying.
Moreover, the team's batting heavily depends on Brendon McCullum, which is another major reason for top order collapse.
"We could have been staring down the barrel of a 190, 200 score," Taylor said.
Chasing 178 for victory, New Zealand lost a couple of
wickets early in the innings, which put a lot of pressure on the middle-order.
Though the skipper himself played well to help the team reach 150 plus, it wasn't enough to win the match as they choked and did not play well.
Moreover, it was a wake-up call for New Zealand, as they have to improve all the areas ahead of the Super Eights.
