Dawid Malan's half-century came from 94 balls with seven fours in 141 minutes. It's his sixth Test fifty.
A boundary! Hallelujah.
Dawid Malan guides it through gully to the fence to bring up his fifty. A fine knock so far, with some sumptuous shots, in stark contrast to his woeful first innings.

It's been thrilling though, Simon.
It's very hard to score runs when the ball isn't being bowled.

I think I've commentated on 2.4 overs since my commentary stint began.
Lead by 285
New Zealand have seven men on the off side so Root tries to flick one outside off stump through leg but misses.
That's a maiden for Wagner, the game approaching a standstill at the moment.

We've had 17 overs in an hour and 20 minutes of cricket.
The over rate has been pretty dire today. Neil Wagner takes an age to tie his shoelaces before starting his over.
"Get on with it," shouts someone in the crowd, no doubt an England fan.

If England can't bowl New Zealand out in 140 overs, you'd be disappointed, even in these quite benign conditions. There's a lot on Joe Root. He's the central figure in this game from now on.
Still no new ball taken so Colin de Grandhomme trundles in again.
He drags one down and Root cuts it away for a single.

Jack Kelly: As Root reaches 50, I recall the endless comparisons between him and Steve Smith during the Ashes. Where do we stand on that debate now then?

Before Joe Root became captain, he had scored 4,594 runs at 52.8, with 11 hundreds and 27 fifties.
Since becoming captain he's made 1,264 runs at 54.17, with two hundreds and 12 fifties.
Root 52, Malan 48
Wagner gets an attempted slower ball wrong and sends down a full toss that is called a no ball, with Root guiding it away for one. No menace in that from Wagner but he'll have to be careful - another one and he'll be taken off.
Malan scurries a risky single to mid-on, putting in a dive that would not have saved him had the throw hit the stumps. But it slid past and Malan survives.
Root scythes a square drive away for one more.
It's been a very lengthy drinks break. Not good for the game but it has allowed me to polish off a pack of watermelon cubes.
Dawid Malan is fiddling about with his glove. Meanwhile, it looks like Neil Wagner will continue with the old ball.
Just seen a wagon wheel of Root's innings so far - he's not scored a run down the ground and barely any through cover, showing how he's been content to nudge and nurdle square on both sides.

It's a polished innings. By Root's standards, he's taken quite a long time to get there. He's got a chance to get a hundred here but it's probably the last thing on his mind. He's looked good, quite measured.
Lead by 280
Malan slices a drive off a thick outside edge through third man for four.
That's the 250 up and that'll be drinks.

Root's half-century came from 110 balls with four fours in 148 minutes. It's his seventh of the winter and his 39th in Tests.
Root tucks it away square into the leg side to jog through for an easy single and bring up his fifty.
He's looked in fine fettle, happy to just steadily accumulate.
That perennial question for Root - can he convert?
Vic Marks
Ex-England spinner on BBC Test Match Special
Not taking the new ball means that New Zealand don't think they can bowl England out. The new ball, as we know, has worked in this game.
