Wicketkeeper Brendon McCullum hit his highest Test score to help New Zealand to take control after day three of the first Test against Bangladesh on Thursday.
Bangladesh suffered early blows in the second innings losing two quick wickets and slumping to 41-2 at stumps, still trailing by 184 runs.
Nafis Iqbal was unbeaten on 24 with Rajin Saleh yet to score at the close of play.
McCullum made 143 in New Zealand first innings total of 402 in reply to Bangladesh's 177.
Left-arm spinner Daniel Vettori then took two quick wickets to reduce the home side to 41 for two at the close.
McCullum was ably assisted by the tailenders after New Zealand resumed on 207 for five.
After Jacob Oram had departed for 23, Vettori (23), James Franklin (23, Paul Wiseman (28) and Ian Butler (15 not out) kept Bangladesh in the field until just after the tea interval.
Left-arm spinner Mohammad Rafique was the most successful bowler with figures of six for 122, his fourth five-wicket haul in Tests, to become the first Bangladesh bowler to take fifty wickets in Test cricket.
McCullum was again to the fore when Bangladesh batted again, catching Javed Omar off Vettori for 14. Vettori followed up by holding a return catch to dismiss Hannan Sarkar for one.
