Bairstow continued his remarkable scoring streak with an unbeaten 71, including the second fastest half-century by any Englishman in Test cricket, as the home side romped to a sizeable victory target without ever really appearing to be in trouble
Headingley (final day of five): New Zealand 329 & 326, England 360 & 296-3 - England won by seven wickets
England completed a whitewash of the world champions in their first series under new management, as Jonny Bairstow led from the front on the final day at Headingley.
Bairstow continued his remarkable scoring streak with an unbeaten 71, including the second fastest half-century by any Englishman in Test cricket, as the home side romped to a sizeable victory target without ever really appearing to be in any kind of bother.
The Leeds crowd, who had been made to wait for the action until 1.30pm on Monday because of rain, enjoyed their free day out - Yorkshire gave away all tickets to the last day - immensely as Bairstow and Joe Root jogged their way to the 113 more runs they needed for victory in less than an hour and a half's playing time.

Once again, New Zealand could do little to thwart this combative, apparently fearless new England under Brendon McCullum and Ben Stokes.
While Ollie Pope was dismissed in the first over of the day for 82, bowled through the gate by a tremendous delivery by Tim Southee, Bairstow and Root were once again in serene nick.
Bairstow took a liking to Trent Boult, square and straight driving the left-armer at will, and spinner Michael Bracewell came in for similar treatment, as Root simply allowed his partner to go about his business.
And he did so in some style, smashing Bracewell for a six to win the game at his home ground. He made his runs from just 44 deliveries. Root was 86 not out at the other end.
For England, this was another extraordinary recovery after they found themselves 55 for 6 in their first innings, responding to the Kiwis' 329.

It was Bairstow then, just as it had been in the victory at Trent Bridge, who provided the power and passion to turn the game on its head, coming together in a huge stand for the seventh wicket with Jamie Overton.
Overton made 97 and Bairstow 162 to give England a narrow lead and, though Daryl Mitchell and Tom Blundell again combined to give New Zealand something to defend, the Blackcaps simply had no answer to their hosts across the final day of the match.
England, who had won one Test in 17 before this summer, have now won three in a row. Next up is India, in Birmingham from Friday.
It will be a fascinating encounter.
