Bangladesh reached 51 for two after 10 overs in pursuit of a 248-run target against New Zealand, following a brief top-order collapse sparked by fast bowler Nathan Smith.
New Zealand posted 247 for eight in their allotted 50 overs after winning the toss and electing to bat first, anchored by half-centuries from Henry Nicholls and Dean Foxcroft.
In the chase, Bangladesh encountered immediate trouble in the fourth over. Smith bowled opener Tanzid Hasan for two and dismissed Najmul Hossain Shanto for a first-ball duck on consecutive deliveries, leaving the hosts at 21 for two.
Saif Hassan, unbeaten on 18, and wicketkeeper Litton Das, not out on 15, navigated Bangladesh through the remainder of the initial overs without further loss. The team requires another 197 runs from 40 overs to secure a victory.
Earlier, Nicholls stabilised the New Zealand innings after the early loss of opener Nick Kelly, constructing a measured 68 from 83 deliveries, including nine boundaries. He shared a 73-run partnership with Will Young, who contributed 30, before falling to leg-spinner Rishad Hossain in the 28th over.
Foxcroft accelerated the scoring rate in the lower middle order, striking eight boundaries to compile a brisk 59 from 58 balls. Smith provided late momentum to the innings with an unbeaten 21 off 22 deliveries.
The Bangladesh bowling attack utilised a collective effort to restrict the scoring. Left-arm fast bowler Shoriful Islam delivered the most economical spell, conceding 27 runs and claiming two wickets across his 10 overs, which included two maidens.
Fast bowler Taskin Ahmed and Rishad Hossain also secured two wickets each, conceding 50 and 44 runs, respectively. Off-spinner Mehidy Hasan Miraz and fast bowler Nahid Rana claimed one wicket apiece, though Rana proved expensive, yielding 65 runs in his 10 overs.
