Brilliant shots. They are slightly risky but that is Jonny Bairstow.

And that's the best of the lot, Bairstow cutting it just behind square for the third four of the over.

And another! This time he drives it more in front of the wicket to drill another boundary, following it with two to third off the next.

That's more like it, Jonny!

Boult goes wide and Bairstow leans into it to guide the ball to the boundary past point.

Ouch! Jamieson gets one to climb back up the hill and into the under edge of Root's bat and into his inner thigh. That's got to sting.

Ollie Pope has faced 47 balls from left-arm pace bowlers round the wicket in Tests and has been out three times.

Here's how New Zealand got stuck in after lunch.

Jon: Since when has an innocuous ball outside off, become as vicious & dangerous as an in-swinging yorker? England's 90s batsmen, facing Younis, Akram, Donald & Ambrose must be wishing they could have a bat today.

David Merson: Did England really think they just had to turn up to beat the current World Test Champions?

Dan: Ah 46-3, hello my familiar friend.

If I had bowled a ball like that I'd have done a lap of Lord's.

Second ball in, and Bairstow wafts horribly at a wide one from Boult. It's not a good look at any point, especially after just deliveries.

Michael Vaughan's also just said that was alike a fast Derek Underwood, not many better tributes than that. Pope also may have just got touch to it.

Here's Jonny Bairstow, but this all has a very familiar feeling to it.

That is a peach. Round the wicket and you are expecting it to come down the slope. It is a like a sharp leg-cutter from Boult.

Pope was looking nice. If you get a ball like that there is not a lot you can do.

This time it is Pope who repeats the shot Root essayed just earlier. It goes a bit closer to the boundary but yet again Kane Williamson drags it back.

Tristan. Hook Norton

Shot! Root cover drives Jamieson past mid off for three, it wasn't perfectly timed so did not quite have the legs.

New Zealand are just relentless - experienced, different styles of bowlers.

England have to take a leaf out of Mitchell's book. After 30 or 35 overs the ball did get a bit soft. If they could just not lose a wicket for 10 or 15 overs they could get their rewards.

Boult is now coming round the wicket from the Pavilion End, given the slope and being a left-armer that must be a weird sensation.

But it doesn't bother him as he zips the ball between Pope's bat and midriff and over the sumps.

Ollie Pope chops down on a wide Boult delivery, squirting the ball towards third to grab a scampered two runs.

Joe Root comes into this innings exactly 100 runs away from becoming the second Englishman, after Sir Alastair Cook, to score 10,000 Test runs.

Here are some figures behind the Yorkshireman's career so far...
