FIRST ONE-DAY INTERNATIONAL, Riverside:
England 307-5 bt New Zealand 193 by 114 runs
Pietersen salutes the crowd after striking his sixth ODI century
Kevin Pietersen's century led England to a 114-run win in the first one-day international against New Zealand.
The big right-hander timed his innings perfectly after the loss of Ian Bell had England limping in the 20th over.
Paul Collingwood and Owais Shah also played their part, but Pietersen's 110 was the mainstay of England's 307-5.
New Zealand rarely looked set, Stuart Broad, Graeme Swann and Collingwood sharing eight wickets as the Kiwis fell to 193 all out in the 43rd over.
The defeat continued the Kiwis' demise on this tour, following their 2-0 defeat in the Test series and crushing loss in Friday's Twenty20 international.
And despite coming into the match ranked third in the world in the 50-over format, Black Caps skipper Daniel Vettori will know his side have work to do if they are to get back in the series, with their confidence clearly shattered after seven weeks in England.
The tourists' lack of a killer instinct was clearly evident as they witnessed Pietersen craft a superb sixth one-day international century after a decent, if unexplosive, start from England's other top-order batsmen.
To his credit, Bell picked up where he left off in Friday's Twenty20 international, making the most of a reprieve when he was caught behind off a Kyle Mills no-ball first up to take 11 off the seamer's opening over.
As he continued to play his shots, producing a wonderful pick-up six off his legs in the fourth over, Luke Wright struggled to get the ball off the square at the other end and, after just one four in 33 deliveries, the Sussex man lost his cool and spooned a catch straight to Vettori at mid-off to go for 11.
That brought Pietersen to the crease, but he refused to take chances off the powerplay overs as he and Bell nudged and nurdled England towards 100.
Bell continued as the main aggressor, but he fell for 46 to a fine direct hit from Taylor at mid-wicket to end an encouraging innings.
Ravi Bopara, fresh from a stunning 201 not out against Leicestershire for Essex 10 days ago, seemed the ideal man to pick up the pace for England, but when he fell for just four, offering a return catch to Scott Styris, England's innings looked in danger of stagnating.
However, without the accurate pace bowling of the injured Jacob Oram, New Zealand were always going to struggle to shore up the scoring from both ends and Pietersen and Collingwood took their time in building a big score.
Despite taking three early wickets, New Zealand could not contain England
Collingwood, so out of touch in the Test series, looked a man reborn on his home ground and he drove Styris to long-on and cut him down to third man for successive boundaries to kick off his innings.
The pair increasingly took the attack to the Kiwis and shared a 126-run fourth-wicket stand.
And Pietersen underlined his brilliance, and his confidence, by reverse-sweeping Styris for two huge maximums, one over mid-wicket and the other over mid-off.
Even when Collingwood fell, chopping Daniel Vettori onto his own stumps for a well made 64 that had included four fours and two sixes, England continued apace with Owais Shah providing a brutal cameo.
The Middlesex man only had six overs in which to do the damage, but it was all he needed as he crashed three huge sixes on his way to 49 off 25 balls.
At the other end, Pietersen brought up his century with a flick on the pull for a single, and despite Shah falling in the final over, chipping Tim Southee to How at long-on, England's total always looked too much for New Zealand.
New Zealand's hopes rested, almost solely, on the shoulders of Brendon McCullum, playing as a batsmen only because of problems with his back.
He came to the crease with typical abandon and, with the opening few overs flying to all parts, England fans could have been forgiven for wondering if their side's total was enough.
Both James Anderson and Ryan Sidebottom came in for some stick, McCullum hitting a six and four fours over and through point, and only eight overs had been bowled when the Kiwis raced past 50.
The introduction of Broad paid immediate dividends, though, as McCullum fell to his first ball - Bell taking an easy catch at extra cover - and the impetus of the Kiwi innings was never regained.
Stuart Broad, centre, was superb in his opening seven overs for England
James Marshall was the next man out, Collingwood throwing down the stumps from backward point, and when Broad had James How caught at extra cover, New Zealand had lost three wickets for 20 runs in 10 overs.
Thereafter, with the asking-rate building all the time, Collingwood was able to manoeuvre his field and change his bowling options at will, typified when Wright had another dangerman in Ross Taylor caught at mid-on.
Swann, impressive in the Twenty20 match on Friday, continued where he left off and he induced a false stroke from Styris, Anderson holding a simple high catch at deep mid-wicket.
Daniel Flynn and Gareth Hopkins did their best to keep New Zealand hopes alive, the former battling impressively with three fours - including a fine sweep through mid-wicket - to delay England's victory march.
But when he was caught behind off Swann, replays suggesting it may have come off the thigh pad, Collingwood introduced himself to instigate a woeful Kiwi collapse.
The England skipper took the final four wickets, including two in his first over, Hopkins cutting straight to backward point and Vettori top-edging straight to deep mid-wicket.
Kyle Mills's four through long-on held up the inevitable, but only for an over as Collingwood returned to account for the tail-ender, caught over his shoulder well by Wright, and Tim Southee was the last man out when he dollied a top-edge straight to Bell at cover.
It rounded off a one-sided match and England will hope for the same again when the two sides meet in the second one-dayer at Edgbaston on Wednesday.
