Waseem holed out to Tim Southee in the 11th over but Khan ensured the UAE won when he sealed the result with two fours and a six against Southee in the 16th over.
New Zealand didn’t gain any momentum on another slow pitch at Dubai International Stadium as Aayan bowled brilliantly in the powerplay. New Zealand’s ploy to send Mitchell Santner at No. 3 backfired as Aayan chipped in with two wickets off successive deliveries when he clean bowled Santner and Dane Cleaver.
New Zealand was 38-4 in the seventh over when Aayan had Chad Bowes stumped.
Chapman and Neesham tried to rebuild the innings with a 53-run stand but the UAE didn’t allow the Kiwis to accelerate in the death overs. Chapman was one of only three batters to get into double figures.
Fast bowler Mohammad Jawadullah braved cramps in the latter half of the New Zealand innings to finish with 2-16.
The third and final game is on Sunday. New Zealand rested key T20 players for the UAE series, and moves on to England for a limited-overs series.
