New Zealand booked their place in the Super 8 phase after comfortably beating Kenya by 148 runs in St Lucia.
Kenya's top-order quartet David Obuya, Maurice Ouma, Steve Tikolo and Tanmay Mishra all fell early while superb Kiwi fielding engineered three run-outs.
Only Ravindu Shah (71) and Thomas Odoyo (42) provided resistance as Kenya were bowled out for 183 in their final over.
Ross Taylor, Stephen Fleming, Scott Styris and Craig McMillan earlier hit half-centuries in New Zealand's 331-7.
Kenya captain Tikolo had elected to field after winning the toss on a slow-looking wicket, and Odoyo had opener Lou Vincent caught at slip for a duck in the first over.
But then Fleming and Taylor put on 105, and the Kiwi skipper hit three huge sixes and seven fours before running himself out for 60.
Mishra, who had dropped Taylor in the fourth over, then spilled a seemingly comfortable catch from Styris off the bowling of Tikolo when he was on 20.
The Kiwis' total was also boosted as Kenya sent down 21 wides.
Taylor pulled up with a hamstring problem - which will rule him out of their final group game against Canada - while 72 not out and required treatment.
Vincent briefly re-emerged as his runner, and Taylor lofted a six over midwicket before he pushed a soft return catch to Tikolo's gentle off-spin for 85.
It left Styris and McMillan to push the score along before Styris holed out in the deep for 63 off 62 balls.
The bearded McMillan's destructive qualities took the score over 300 with his 71, including five sixes, coming from just 48 balls, leaving them on course to book their place in the second phase.
Seamer Michael Mason, preferred to spinner Jeetan Patel in the line-up, struck early for the Kiwis when he trapped David Obuya lbw in the third over.
Odoyo celebrates his wicket from the fourth ball of the day
Ouma was then superbly run out by a direct hit from Vincent as Kenya pushed for a quick single in the sixth.
Despite a couple of brief rain delays, Mason soon claimed the key wicket of Tikolo, who spooned a catch to Vettori, while Mishra failed to atone for his fielding errors when he edged James Franklin to Fleming at slip.
As New Zealand hurried on to make sure the game reached the 20-over mark in order to constitute a match, it left Kenya vulnerable to a heavy defeat under the Duckworth-Lewis formula if the rain came again.
Collins Obuya (21) was comically run out going for a second run when Shah stayed in his crease as the Kiwis removed the bails with both batsmen stranded at the same end.
Shah and Odoyo gave the score respectability, but Shah's dismissal at 122-6 left Kenya looking unlikely to force an upset.
Jimmy Kamande was bowled by a slower ball from Vettori while aiming an agricultural swipe across the line, while Lameck Onyango became the third run-out victim of the innings after another direct hit from the livewire Vincent.
Odoyo was ninth man out when he lifted Shane Bond to Jacob Oram in the covers, and Franklin picked up his second wicket when Peter Ongondo skied a bouncer which the bowler caught himself.
The heavy defeat also leaves Kenya's net run-rate well adrift of England's in Group C, which would send Michael Vaughan's side through if the weather were to wash out their final group game on Saturday.
