A 5-0 series victory would take New Zealand to second in the world, a 3-2 loss would keep them third.
England have revamped after missing the World Cup quarter-finals. That tournament included arguably the most comprehensive mismatch between the countries, when England were dismissed for 123 in Wellington and New Zealand reached the target with eight wickets, 226 balls and a floodlight power bill to spare.
Forget batting averages or bowling economy rates. This team have forged a reputation on aggression where, in most circumstances, an innings of 40 runs off 25 balls trumps 70 runs off 100 balls, and 4-60 beats 0-40 from a 10-over spell.
Expect the boundary to take an early peppering with the bat, and at least three slips and a gully to be in place with the ball.
Of the eight frontline batsmen in New Zealand's squad who have played ODIs, most sustained or upped their strike rates last summer compared with their careers. McCullum (141 per 100 balls v 94) accelerated the most, but Grant Elliott (100 v 79), Kane Williamson (89 v 82) and Martin Guptill (88 v 83) made significant gains.
Corey Anderson suffered the biggest drop (103 v 123) followed by Ross Taylor (76 v 81).
In Anderson's defence, he set himself a difficult task after his sixth ODI innings in January 2014 when he reached a century in a world-record 36 balls and eventually made 131 not out from 47.
Taylor's strike rate has dropped but his average last season (50.37) overshadows that of his career (41.40).
The batting of left-arm orthodox all-rounder Mitchell Santner also intrigues, as New Zealand seek to fill the void left by the retirement of Daniel Vettori.
Santner impressed with 94 as a makeshift No 3 in the first-class match against Somerset and his record suggests he's capable of scoring quickly.
Strike rates have also been a feature of New Zealand's bowlers.
Of the seven frontline bowlers, most sustained or lowered their numbers last summer compared with their careers. Trent Boult (28 balls per wicket v 33), Tim Southee (31 v 35) and Elliott (23 v 30) made the biggest gains and McClenaghan, the second-equal-fastest bowler to 50 ODI wickets, dropped (34 v 26).
The upshot is to expect some spectacular cricket by a New Zealand team with a carte blanche approach to pursue new ODI boundaries.
