New Zealand can blame themselves. During the 3rd match, they needed 2 runs from the last 4 balls and during the 4th match they needed 3 runs from 4 balls (with plenty of wickets to spare). From that position, they went on to lose the match. I can understand if it happens once. But twice? Common.. you need to find an excuse other than injury for this sham. The Kiwis have been performing exceptionally well till then. Their performance during the CWC 2019 was top notch. But all the reputation that was earned till then was lost as a result of their poor performance in the T20 series.
