Maybe not. The field is a bit of a bluff as Wagner goes full and tries to find some swing.

He does but nothing late enough to trouble Root or Brook. Four from the over.

Neil Wagner is about to come on and replace Mitchell. Two men back on the hook already suggest - green seamer or not - he wants to test out the middle of the pitch.

Tim Southee is back into the attack and starts with a maiden. Nothing for Root to work with.

Tom: This has either 450-plus all out or 120 all out written all over it.

That fielder out at deep backward point is frustrating Root as he twice nails his late cut but, even when he gets the second of them that much finer, he has to settle for singles.

Brook shows him how to find the boundary, front foot down the track and thump the ball back over mid-off! Simple.

Sir Alastair Cook noticed a small technical change from Zak Crawley. We think he might have gone across his off stump - the benefit of doing that as a batter is that you're able to leave the balls that are outside your eye-line.

So maybe pushing outside his body, but it's a green top and it's nipped away, catching the shoulder of the bat. You have to say that where New Zealand lacked discipline in the previous Test they've very much had it here.

Matt Henry continues after drinks and following five dot balls, Joe Root drops the last delivery into the covers and scampers through for a quick single.

That is one of the most compelling first hours of a Test you could ever see.

Tom Blundell is up to the stumps for Mitchell's second over, ensuring Root stays firmly in his crease.

The former England skipper is able to get his favourite late cut out early in the over but there is a fielder out at deep point to keep it to one.

Three singles from the over as the tourists try to calm things down a bit - not something we've seen a lot of recently. Time for drinks.

A missed opportunity, Matt. Still plenty of time for him yet though. Never write him off!

England reach the first marker of the innings, four leg byes taking them to 50.

They're under the cosh but are still going at over four an over.

After nearly getting a full ball through Brook's defences, Henry surprises the England batter with a short ball.

The ball loops up towards gully but falls just short in the end.

If Joe Root gets any further out of his crease, he'll be batting at the non-striker's end.

A maiden to start from Mitchell and I can confirm that he looks a handful on this pitch, nibbling it around.

Root's response is to advance down the track and negate the seam movement where he can.

It's not getting any easer out there, though.

If you want to know what type of pitch this is, New Zealand are bringing on Daryl Mitchell to bowl his medium pacers - and I fancy he'll be a bit of a handful.

Joe Root has his first boundary, driving just backwards of point and the ball races away. It was a little edgy but all along the ground.

Anyway, that's the powerplay done.

Steady on, Stephan!
