Sean Broughton: Stokes opening the bowling off a few paces? What's wrong with the conventional choices of Broad and Anderson?

They're holding Broad and Anderson back for the second new ball, which is due in three overs.

These are some cracking shots from Southee. Maybe it's because Mark Wood isn't used to doing it but when he does bowl short, it's a little wide. If it's wide, and you've got a great eye, then you've got room to swing those arms.

Mark Wood continues and BJ Watling gets his first run of the day, driving wide of mid-off for a single. The Kiwi keeper stumbles over as he makes his ground but he was easily safe.

Shot! Tim Southee batters a full ball straight back past a startled Wood and down the ground for four. He's going to play some shots before the new ball.

Four more! Short this time and Southee swivels a pull in front of square to the fence. The lead is already under 100.

Better from Stokes. Three dot balls to finish.

Southee's the danger man for me. He doesn't like the short ball much but he's got a very good eye, and he can hit a clean ball.

NZ 200-6published at 75.3 overs

75.3 overs

It'll be Ben Stokes to bowl some of these final five overs until the new ball.

Southee tucks off his legs for two before he clatters a long hop over mid-wicket for six! Cracking shot.

That's the 200 up for New Zealand.

There isn't a cloud is the sky. It's a beautiful day. A good day to bat, you'd imagine.

Full. Blocked. No run. On we go...

Here is Mark Wood to bowl the first ball of the day and the last ball of his over that he started yesterday...

This is the moving day. At the end of today we will know the course of the rest of the match.

Talking of Tim Southee - he's striding out to the middle alongside BJ Watling in Christchurch.

England are out there too and play will be under way shortly.

Ruth Brooksbank: We need to get Southee out quickly as he could add some valuable runs - remember that 77 off about 40 balls in 2008 at Napier?

Stuart Broad was our best bowler yesterday because of how full he bowled. If you bowl full, the batsmen cannot help but drive - and even if it only moves half an inch, you entice the drive and it gets the edge.

England pace bowler James Anderson on TMS: "Stuart Broad's a great example for the rest of the team - a senior bowler with 400 wickets is still putting in hard work on his action, and he was fantastic yesterday - we're hoping for more of the same today.

"They [BJ Watling and Colin de Grandhomme] both dug in pretty well yesterday - I don't think we could have done much more. If we can get a lead of 60-80, that would be terrific, but that means we'll have to bowl very well. We'll have to be right on the money with that second new ball."

We've seen how the likes of Boult, Starc and Southee how they're happy to risk a couple of boundaries early on by bowling fuller, in the hope of getting movement. Maybe cricketers get cagier as they get older?

England pace bowler Stuart Broad on TMS: "It's the best I've felt for a while. I felt strong at the crease, my wrist was in a good position and I got the ball moving."

Despite what Stuart Broad said, that bumper barrage didn't work yesterday. Just because it works against England's batsmen, doesn't mean it will work against everyone else! I was surprised how quickly they went to it - even with New Zealand five down, De Grandhomme got that bumper barrage and hit three boundaries.

Who should England use to bowl these five overs before the new ball is due? Do you save Anderson and Broad for the 81st over?

Broad has been the most dangerous bowler, so he's your trump card with the new ball. So I might go with Wood at the start - while Southee might not know whether to take Leach on.

Graeme Swann adds: I'd go Wood and Leach for the first five overs. Southee won't like the extra pace of Wood.
