New Zealand set a 209-run target for Bangladesh in the tri-nation T20I series at Hagley Oval in Christchurch on Wednesday.
New Zealand scored 208 runs losing 5 wickets in 20 overs.
Earlier, Bangladesh won the toss and chose to bowl against New Zealand in the match.
Bangladesh are in the completely back foot after losing their first two matches at the hands of Pakistan and New Zealand. While they remain win-less so far, both Pakistan and New Zealand won two matches in three and have already moved clearly to confirm the final.
But mathematically, Bangladesh still have the chance even though their road to confirm final will be extremely tougher. They not only have to win both of their return leg matches against New Zealand and Pakistan but also need to improve their run rate, which is so poor following their abysmal batting performance in the first two matches.
Bangladesh lost their first game to Pakistan by 21 runs when they were in good position to win the game. But they were restricted to 146-8, chasing the target of just 168.
Against New Zealand, they again came up with vulnerable batting show to be held back to 137-8, which New Zealand gunned down with ease to win the game by eight wickets.
