Bangladesh are on the verge of an innings defeat after closing day two of the second Test at 51-5, still 199 runs from making New Zealand bat again.
The Kiwis, who won the first match by nine wickets, were indebted to captains past and present Stephen Fleming and Daniel Vettori, as they posted 393.
Fleming made 87, his 43rd Test fifty, while Vettori was denied a third Test ton after 17 fours in 94 from 87 balls.
Faced with a deficit of 250, Bangladesh soon lost three wickets in three overs.
Resuming only nine runs behind at 134-3, the Kiwis were given a reprieve in the first over when Mathew Sinclair was dropped by Tamim Iqbal at first slip.
Sinclair was dropped again by keeper Mushfiqur Rahim and the problems continued for the Tigers when Shahriar Nafees fumbled a chance above his head after Fleming mis-timed a lofted drive.
The left-hander then hit three successive boundaries in the next over before he was finally caught at deep mid-wicket having failed to give his launch into the leg-side sufficent steam.
Vettori opened his account with four successive boundaries off Sajidul Islam and after the bowler tried to stem the boundaries by sending down a wide, the next legitimate delivery was battered through mid-wicket for four more.
Skipper Mohammad Ashraful was another to err in the field, making a mess of a routine chance chipped to him at mid-on by Vettori when 74.
One hit away from three figures, Vettori got through his shot too early against the gentle Aftab Ahmed and presented a simpe return catch. New Zealand quickly got amongst the Bangladesh batsmen when the beleagured Tigers batted again.
The clatter of wickets began in the sixth over when Junaid Siddique gloved a short ball from Kyle Mills and opening partner Nafees was back with him in the pavilion in the next over when he edged to second slip.
Only veteran Habibul Bashar defied the home attack, with three fours in a patient unbeaten 21 from 49 balls.
New Zealand's certain victory may come even earlier on day three, weather permitting, with Tigers batsman Tamim Iqbal unlikely to feature because of a broken thumb.
