Third Test, Trent Bridge (day two, close)
England 364 v New Zealand 96-6
Brendon McCullum surveys the damage as Anderson strikes
James Anderson took a Test-best 6-42 as New Zealand closed day two of the final Test 268 behind England on 96-6.
Anderson struck with his third ball and produced a superb spell of swing.
Ross Taylor and Daniel Flynn fell in the same over to rock the tourists' hopes of levelling the series, before bad light ended play at Trent Bridge.
Anderson's dream day began with his highest Test score (28) in a 76 stand with Stuart Broad, who hit a first Test fifty as England added 91 to reach 364.
Broad and Anderson would no doubt have arrived at the ground thinking it was a good day to bowl, given largely overcast skies and the notorious swinging conditions beside the River Trent.
But they were first intent on giving themselves plenty of runs to bowl with as England, who lead the series 1-0, resumed on 273-7.
There was a fair amount of good fortune, and several shots came off the edge through the slip and gully area, but the left-handers dug in to produce an admirable partnership.
In the third over, first-choice wicket-keeper Brendon McCullum, playing as a specialist batsman because of a bad back, but promoted to number three, fumbled a regulation catch at second slip when Broad edged on 21.
That would have made it 279-8 and the left-handers made the tourists pay for the profligacy.
For all the elements of luck, there were far more genuine strokes, from both players.
Broad passed his previous highest of 42 with two classical boundaries reminiscent of his father Chris in his pomp during the 1986-87 Ashes, a back foot punch followed by a dreamy cover drive.
McCullum also dropped a catch that allowed crucial extra runs
The 21-year-old, playing in his sixth Test, spent 25 balls on 49 either side of lunch but duly recorded what England hope will be the first of many half centuries before he was the ninth wicket to fall.
Monty Panesar received a tumultuous reception but failed to trouble the scorers, and although he appeared harshly done by when given out caught at silly point, his duck is unlikely to be of great significance.
Having mustered a strong total, not the 477 they made at the ground in the 2005 Ashes but considerably better than 198 against India last year, it was time for England to exploit the helpful bowling conditions.
Although Ryan Sidebottom was unable to find his best rhythm, Anderson was immediately in tune, pitching the ball on a full length and finding reward with prodigious movement.
The Kiwis could not cope with the swinging ball and Aaron Redmond was first to fall when he tried to flick through mid-wicket, missed the swinging ball and had his off-stump taken out.
The same pole was soon cartwheeling out of the ground again as McCullum, promoted up to number three despite his back concerns, also tried to turn one to leg.
Anderson was a constant threat, swinging the ball away but shaping the occasional surprise ball back in off the seam.
It was also done at pace, and the 25-year-old Lancashire star touched 90mph on occasions in spells from both ends.
Jamie How played in a more circumspect manner than his colleagues, but even a straight bat could not negate Anderson in the form he was in.
More movement found How's edge and Tim Ambrose took an excellent low catch diving forward behind the stumps.
The Kiwis were reprieved for the day when the skies turned to charcoal greyl, but their batting will have to brighten dramatically if they are to avoid a 2-0 series defeat.
