Not for the first time, it was the bowlers who put England in contention, restricting New Zealand to 223 all out. Martin Guptill was the only batsman in the top five to provide any resistance with 47, before Nicholls and Santner ensured New Zealand had a total to bowl at but it was never going to be enough against the powerful England batting lineup. In the end, it was Ben Stokes who finished with a couple of huge sixes off Ish Sodhi and stamped England's authority on what was a thoroughly competitive series barring the last game.
They looked assured in their pursuit of New Zealand's total and played smartly, led by Bairstow as he registered his second century of the series.
But however, this two teams have returned from the last T20I tournament which was Trans Tasman Tri Series where Australia and New Zealand were the local team and England was the guest team.
"(Then) the way the spinners bowled through the middle was really impressive".
Hales reached his half-century in 67 balls before picking out Williamson at mid-wicket in the 24th over to give Santner a wicket.
After achieving one milestone, Bairstow stepped up a gear.
Pace from Trent Boult was pulled for four, while left-arm spin was swept for six.
Bairstow said: "They set the platform as they have done first up all the way though the series".
New Zealand seemed to struggle to read the pitch.
Chris Woakes was the pick of the England bowlers in the fifth ODI with his figures of 3/32 and he would earn the man of the series award. They got victory in the first match. Nicholls hit Root's off-spin for six but he top-edged Tom Curran to short leg at an inopportune moment. But Bairstow's dismissal by part-time medium-pacer Colin Munro, from whom he had just previously hit a six over the gabled grandstand at the University Oval, precipitated a collapse which saw England lose 6-19 in 6.1 overs.
After New Zealand got victory in the first match, England won number two and number three matches consecutively and so, guest team went ahead than New Zealand by 2 - 1 games.
Their patchy play with bat and ball against England, the form ODI side in world cricket, and the comprehensive nature of the defeat in the series decider in Christchurch leaves the Black Caps with more questions than answers. Besides, team England is now travelling Australia and New Zealand for long and so, they have already familiar with the environment.
"Jonny Bairstow's batting was of the highest class. It was a brilliant innings by Jonny - hitting the ball cleanly like he has all series". "No bowler was been able to contain him".
"That's what we're planning on", Bayliss said. "We didn't get a complete performance all series, but England were outstanding, a very good one-day unit, and deserved to win the series".
"It's really pleasing for me to go out and score hundreds - because that's your job".
