An over of relative serenity costs three runs.

Kirkstall S Corlett: For best cricketing nicknames, "The King Of Spain" for Ashley Giles has to be close to the top.

Wow. We have seen some shots for the T20 lovers today but this one would have Geoffrey purring.

Harry Brook, with the fullest face of the bat, smacks the seam of Scott Kuggelijn through the covers.

There have been 15 overs this morning. England have scored 104 runs.

Only a four this time! Neil Wagner is taking a pounding at the hands of Harry Brook now.

We should be used to it but England's approach is once again making me reassess everything I have previously thought about the game.

They're taking risks but as they do they're ensuring the lead they have is rattling up towards a number that starts to worry New Zealand in no time.

Eng 166-4published at 29.3 overs

And the third ball is thwacked back down the ground for six!

Neil Wagner is going at almost 10 runs per over.

Harry Brook begins the second hour by drilling a pull off Neil Wagner to the boundary.

David Fisher: We're safe in this match lads - Joe Root has hit a 6. England have never lost a Test in which Root has hit a 6. Which is quite remarkable given that he's scored 29 of them.

The strange thing is Joe Root's chronic back issue seemed to die down in the last few years, just at the time he was carrying the weight of 10 English Test cricketers.

Five singles from the over.

That brings to an end an entertaining first hour.

Bloody Bishop: The thing Bazball hasn’t changed about this England team is that Root’s the best batsman and Jimmy's the best bowler. It’s allowed space for other to contribute and help them out.

And Harry Brook is taking a similar approach against Wagner's bouncers.

He smashes the latest one but only just out of the reach of Tom Latham at square leg.

Latham stuck up a hand but it almost beat him for pace.

Ollie Pope had 15 from 28 balls and was out for 49 off 46. In the time in between, he took 34 off 17.

It has been pointed out to me that Brendon McCullum's middle name is Barrie which could be the source of the Baz nickname.

Does anyone suit a name less than McCullum and Barrie?

Harry Brook has made a nervous start, playing and missing to one from Scott Kuggeleijn.

That wicket brings Harry Brook to the middle.

Gone this time!

Ollie Pope looks to have gloved a bouncer behind.

They're just checking the catch but it looked good.

It's just a change of ends for Wagner who returns to the attack in place of captain Tim Southee.

It's still the bouncer ploy but rather than hook Ollie Pope just steps away and smacks him through the off side.

That's completely safe. There's no fielder there.

Jay: This is why Jos Buttler or Liam Livingstone should be in this team. They'd be on 60 by now with New Zealand looking for the ball on the neighbouring hockey pitches!

Pope and Root bring up the fifty partnership in Kuggeleijn's first over. It has come from just 38 deliveries.

Matt Taylor: Speaking of cricketing nicknames, it's important to state that the maddest thing about Bazball remains the insistence that 'Baz' is somehow short for 'Brendon'. Baz is, and will only ever be, short for Barry.
