10:34am - Blackcaps bowlers are warming up out in the middle at Hagley Oval, so maybe that's an indication that Latham will send Bangladesh back into bat.
Another beautiful day in Christchurch and no sign of the inclement weather rumoured for later in the match.
Kia ora, good morning and welcome to Newshub's live coverage of the second test between the Blackcaps and Bangladesh at Christchurch's Hagley Oval.
Milestones fell thick and fast during on Monday, with Devon Conway bringing up his third test century on the first ball, Tom Latham following with his second career double century soon after, Ross Taylor's emotional final test innings with the bat and Trent Boult becoming the fourth Kiwi to reach 300 test wickets (behind Sir Richard Hadlee, Daniel Vettori and Tim Southee) with his ninth five-wicket bag.
By the end of the second day, New Zealand held a commanding 395-run first-innings lead, with captain Latham mulling whether to enforce the follow-on or bat again to give Taylor the chance of one final hurrah.
Less than halfway through this match, you can't help but wonder how the world champion Blackcaps succumbed so meekly - their first test loss to Bangladesh - in the opening encounter at Mt Maunganui.
There was some suggestion the weather might pack up later this week, possibly impacting the fourth and fifth days of this fixture, so don't be surprised if Latham elects to send the Tigers back in to bat, with the prospect of ending this affair as quickly as possible.
New Zealand: Tom Latham, Will Young, Devon Conway, Ross Taylor, Henry Nicholls, Daryl Mitchell, Tom Blundell, Kyle Jamieson, Tim Southee, Neil Wagner, Trent Boult
Bangladesh: Shadman Islam, Mohammed Naim, Najmul Hossain Shanto, Mominul Haque, Nurul Hasan, Liton Das, Yasir Ali, Mehidy Hasan, Taskin Ahmed, Ebadot Hossain, Shoriful Islam
TAB Odds: NZ $1.01, draw $24, Bangladesh $94
Blackcaps bowlers take control of second test after Latham double century
The Blackcaps have taken complete control of the second test against Bangladesh, finishing day two with a lead of 395 runs at Christchurch's Hagley Oval.
Centuries to Tom Latham (252) and Devon Conway (109) paved the way for New Zealand to declare their first innings over at 521/6, before Trent Boult (5/43) and Tim Southee (3/28) shone with the ball, bowling Bangladesh out for 126 before stumps.
Boult also had reason to smile, taking his 300th test wicket in his 75th test match, beating longtime teammate Southee by one game.
Yasir Ali (55) offered the only real resistance for Bangladesh, notching his first test half-century, but ultimately ran out of partners and was forced to give his wicket away in search of quick runs.
The Blackcaps are almost certain to enforce the follow-on heading into day three, asking Bangladesh to bat again.
Resuming on 99 on day two, Devon Conway needed one ball to bring up his third test century, glancing to the fine leg for four, but his innings came to an abrupt end on 109, when he was run out by Mehidy Hasan Miraz, as Latham attempted to steal a run to cover.
The runout broke their partnership of 215 runs for the second wicket, but the captain batted on to reach his second test double century - this one from 305 balls with 31 boundaries.
Conway's exit saw Ross Taylor arrive at the crease for what could be his last innings in test cricket.
Already New Zealand's leading test runscorer, Taylor added another 28 to his career tally, before he fell, caught by Shoriful Islam off the bowling of Ebadot Hossain.
Henry Nicholls came and went for a duck, courtesy of Ebadot, while Daryl Mitchell could only add three runs, before he fell to Shoriful for three.
Wicketkeeper Tom Blundell arrived at the crease at No.7 and desperately needing a score, he combined with Latham for a 76-run partnership in just 78 balls.
Latham batted on past 250, taking the attack to Bangladesh captain Mominul Haque and raising his bat again, after plundering 14 runs from the first four balls of the part-time spinner's over.
Chasing quick runs to set up a declaration, Latham departed one ball after reaching 250, when his top-edged sweep was caught by Yasir Ali off Mominul, and left to a standing ovation from his home crowd at Hagley Oval.
Buoyed by the loss of his captain, Blundell upped his scoring rate to notch his own half-century, finishing with an unbeaten 57 from 60 balls, as Latham declared at 521/6.
If Bangladesh's day with the ball hadn't gone to plan, things were only going to get worse with bat in hand.
With his second ball, Boult landed the first blow, as Shadman Islam edged to Latham at second slip and Bangladesh's top order collapsed.
At the other end, Southee removed Mohammad Naim for a duck, before Boult had a second, when Najmul Hossain Shanto also edged to Latham.
Southee removed captain Mominul, bowled for a duck, as Bangladesh reached tea at 27/4 - still 494 runs behind.
Boult continued the carnage after the break, removing Litton Das for eight, caught behind by a diving Blundell, as the left-armer reached 299 test wickets.
Yasir Ali and Nurul Hasan steadied Bangladesh's innings, adding 60 runs together for the sixth wicket, but Southee broke the stand, as it threatened to defy the Blackcaps.
Southee trapped Nurul leg before wicket for 41, with the Bangladesh wicketkeeper unsuccessfully challenging the decision to become the sixth batter to fall at 87.
Boult returned to take his 300th, bowling Mehidy Hasan for five to leave Bangladesh seven down, before Kyle Jamieson made it eight with the wicket of Taskin Ahmed, courtesy of a spectacular catch from Will Young.
Yasir batted on to his 50, raising his bat for the first time as a test cricketer, but fell to Jamieson shortly afterwards.
With the final ball of the day, Boult knocked over Shoriful Islam for two, raising the ball for his ninth test five-wicket haul and giving Latham the opportunity to enforce the follow-on overnight.
Victory for the Blackcaps would level the two-match series at 1-1 and give New Zealand their first win of the new World Test Championship cycle.
NZ 521/6 declared (Latham 252, Conway 109, Shoriful 2/79, Ebadot 2/143) Bangladesh 126 (Yasir 55, Boult 5/43, Southee 3/28)
