ICC World Twenty20, Guyana: New Zealand 36-1 (8.1 overs) beat Zimbabwe 85 (15.1 overs) by seven runs
Styris captured three wickets in his opening six deliveries
New Zealand defeated Zimbabwe by seven runs under the Duckworth/Lewis method to reach the ICC World Twenty20 Super Eights after more rain in Guyana.
Zimbabwe were 58-1 before Nathan McCullum took three wickets in an over as five fell for five runs in 15 balls.
Scott Styris also enjoyed a three-wicket over as the final nine went for 26 in a sorry procession and Zimbabwe were 85 all out with 29 balls unused.
New Zealand were ahead of the required rate at 36-1 when rain ended the game.
So the infamous Guyana climate disrupted another match - the third in succession to fall foul of the elements at Providence - but there was little doubt that New Zealand would have completed victory had the weather not intervened.
Zimbabwe failed to hit a boundary in their unsuccessful revised five-over run chase against Sri Lanka on Monday but both openers hit fours within the first two overs as they started fluently.
The diminutive Tatenda Taibu used the pace of Shane Bond effectively with some inventive shots and a lofted Andy Blignaut boundary followed by five wides from Jacob Oram helped them to a useful position at 54-1 after the powerplay.
But there were to be no more boundaries for Zimbabwe in a false dawn beginning with Taibu pulling a slower ball bouncer from Bond to mid-wicket.
Oram atoned for his wayward delivery with some nimble fielding on the boundary, pirouetting and fizzing back to wicketkeeper Gareth Hopkins, who threw down the stumps from close range to beat Hamilton Masakadza's pursuit for a second run.
Skipper Daniel Vettori, who conceded only 10 singles from his 19 deliveries, struck with his second ball, bowling Bilgnaut round his legs via the glove.
McCullum, older brother of Brendon, had bowled two overs for 13 before his remarkable third over, which began when Elton Chigumbura holed out to long-on.
The bespectacled Charles Coventry, who struck an unbeaten 194 in a 50-over international against Bangladesh in 2009, tamely chipped a return catch to the spinner and left-hander Craig Ervine was drawn out of his crease by a flighted off-break and easily stumped.
The evergreen Styris, looking rather more trim than in previous years, then had a devastating impact with his innocuous looking slow medium-pace variations.
Maruma lofted his second ball to long-on, Cremer's timid poke resulted in a inside edge on to pad and then stumps, while Prosper Utseya was plumb leg before wicket prodding forward.
Vettori inflicted the final blow when Ray Price tried an agricultural sweep and saw the top of his off stump knocked back.
Remarkably given such a low target, New Zealand made a nervous start, perhaps wary of the ever darkening skies.

Jesse Ryder top-edged a slog sweep when Utseya got one to turn and Taibu claimed the catch.
The rain did indeed arrive on a stiff breeze with the score on 36-1 in the ninth over but by then Brendon McCullum, who became the first man to pass 1,000 Twenty20 international runs, whipped Utseya through mid-wicket for four and flicked over his shoulder for three in the fifth over to get his team ahead of the required rate.
After more than an hour's delay due to heavy rain there was another Duckworth/Lewis calculation to confront the players, but this time it befitted the balance of play and New Zealand's target became 45 from 11 overs.
The simplicity of that did not last long as another squally shower cut the match further and it became 40 from 10.
In the end there was to be no further action at all as amid much confusion the umpires called things off and the Kiwis moved through from Group B with Sri Lanka.
The complexities of the revised method meant that the winning margin of victory was measured in runs even though New Zealand batted second, with the Kiwis seven runs ahead of the rate.
Vettori was delighted with his team's performance and said: "After a tough start it was good to fight back in those middle stages particularly with Nathan McCullum and Scott Styris, those two three-wicket overs really helped us.
"I think we knew it would be a difficult wicket to bat on later on with Zimbabwe having so many spin bowlers but the confidence in the middles stages, which we have shown in in a number of T20 games, was there and we were pleased with it again."
Counterpart Utseya lamented his side's capitulation and said: "We are disappointed, we had a good start but didn't make use of it.
"I think it was a bit of inexperience, in the two warm-up games we had been struggling up front and I thought the guys in the middle order tried not to play themselves in.
"The potential is there it is just consistency that's lacking at the moment. If you want to play at the highest level you have to mature as a cricketer."
