"Yesterday Southee looked as though he was struggling. Today he's finally found his rhythm. The luck has changed around as well - edges that were dropping short yesterday are carrying today."

"This slip cordon is working very nicely and confidently together with each other."

"That's the best catch of the lot. What an opportunity New Zealand now have to win this match and level this series."

Another one gone, and another slip catch! Moeen edges, this time it's third slip Martin Guptill with safe hands and it's seven wickets lost for 52 runs. Southee has three wickets in 17 balls this morning, figures of 3-1-6-3 today., and England are 31-6 with the new ball.

"Stuart Broad has 23 runs in his last six Test innings."

New batsman Stuart Broad - who looks a world away from the man who scored 169 in a Test in 2010 - is nearly out first ball as he jabs the ball just wide of short leg and they run one.

"Southee's just starting to hit form. At Lord's he looked just short of a gallop, but now he's starting to get back to using the crease very nicely, and getting the right line so that he draws the stroke."

Buttler goes! Again a Southee late outswinger does the trick as Buttler plays defensively, this time it's Ross Taylor at first slip taking a regulation catch. England have lost six wickets for 51 runs.

"There's a lot about slip fielding that isn't apparent. You're constantly adjusting. For me the key is to see the ball got through to the keeper, watch the pace, and imagine it coming to you every ball."

Wisden editor Lawrence Booth: Since his 143 in the first innings in Antigua, Bell's Test scores are: 11, 1, 0, 0, 1, 29 and now 12.

Barney: Ian Bell rarely looks out of touch but this series he has looked all at sea with the willow; and in the slips. Worrying times.

While a certain breed of England fans are sharpening their knives and prepare to throw them in the direction of Ian Bell (it's clearly his turn to be the "batsman under pressure", a role which is a mainstay of any England side), there are also reports of rain on the way... meanwhile, Moeen Ali sees off a maiden from Boult.

Merlyn: Ian Bell once again proves that he is not the man for any kind of tough situation. Can we dispense with his services?

Adam Wheeler: Some poor form from Bell. Will he be looking over his shoulder.

Joe Robinson: Ian Bell having an absolute nightmare. Lucky for him there's no outstanding middle order batsmen who could replace him...

"New Zealand's third innings could be England's best chance of winning, if they go at it in a headless fashion."

Finally England put bat to ball in the runs department, as Moeen is off the mark with a nudge off his legs for one. Buttler drives at an outswinger and gets an edge... and the ball sails just wide of Kane Williamson at gully. England survive, and Buttler is in double figures.

Simon Goodall: I hope we do a NZ here and play a few shots. Defending and defending will only cost wickets.

Tom Holmes: Big wicket that. England need these two to counter punch because there's not much coming after them.

"I'm surprised they haven't got the lights on. They've got them, why not use them?"

Some Minions, external take their place in the stands as Boult pings in a bouncer which flies over Buttler's head and over the grasp of keeper Luke Ronchi, who is unlucky to be charged with four byes for a delivery which he had little chance of reaching, though he gets the very tip of his glove to it. Next ball, it's Buttler's turn to suffer as an inswinger whacks him in the unmentionables. Three maidens so far today.

"I thought at the beginning of the day that parity would be the most likely scenario. But with the ball swinging, now you think there's the possibility of maybe a bit of a lead for New Zealand."

Stephan Shemilt
BBC Sport at Headingley

"That's poor from Ian Bell, almost an exact replica of his second-innings dismissal at Lord's, when England were in similar peril. If some pieces of the Ashes jigsaw are in place, then Bell's form is one that doesn't quite fit at the moment. Still, Moeen Ali is 108 not out at Headingley."

Moeen Ali returns to the scene of his heroic backs-to-the-wall hundred against Sri Lanka last year, with three slips, gully and a short leg in attendance. He sees off a wicket maiden, Southee takes his cap with the smile of a cheeky schoolboy, and England are yet to score a run off the bat today.
