Johnson is greeted to to bowling crease by Ronchi rocking onto the front foot and cracking it through the covers for four. The left-arm quick is really bending his back as one flies through to the keeper at nearly 150km/h.
Australia fought it out in the face of some good bowling and a very slow wicket, which made stroke-making extremely difficult. At the end of 50 overs, New Zealand have been set a target of 244 runs for victory. It is probably a par score as it will be hard work for the Black Caps to knock off the runs. It is difficult to pick a winner, as Australia will be fighting for survival in the tournament when they come out to field. New Zealand however, will be the slightly happier of the two sides at the break. I think we could be in for a really close finish this evening. One this is for sure, there will be nothing held back, as each side would love to get one over their neighbour.
McCleneghan bowls the last over and will be looking for one more wicket in order to claim a five wicket haul. The wicket he was looking for does not come, but he does a great job in restricting the runs in this final over.
Maxwell eventually connects with a Williamson delivery and sends it over mid-wicket for a six. A reverse-hit earns the batsmen four more runs. The gamble to keep the part-timer going has back-fired as another one sails into the crowd.
A clever sweep brings Johnson his first runs. He then backs away and hits a McCleneghan full-toss through wide mid-off for another boundary. WICKET. The bowler lands the ball, which sticks in the surface and causes Johnson to hit it straight to cover.
WICKET. Faulkner advances and slaps Wialliamson straight to mid-off. The Aussie batsmen are really finding it difficult to come to terms with the lack of pace in the wicket. Another good over for New Zealand as Australia limp towards to end of the innings.
Faulker advances done the pitch in an attempt to make something happen. The left-arm quick from New Zealand is doing a good job though as the batsmen are not reading his change of pace at all.
Williamson is starting to get some serious turn from the pitch. It is another very good over for New Zealand. The spinner's overs at the death must be seen as a bonus.
WICKET. The set batsman is gone as Voges hits a McCleneghan full-toss straight to short cover. Faulkner is the new man to the crease. Australia now have two new batsmen at a time when they would like to launch, which is far from ideal. A single gets Australia to 200 which would have been their first target.
Maxwell is the new batsman. he can also hit the ball along way and will want to make his mark. Williamson is showing how much more difficult it is to attack against the spinner as only a couple singles come from the over.
McCleneghan is back into the attack as we near the stage where Australia will look to tee-off. Voges plays effective straight drive and gets the boundary that is required off the over. WICKET. Marsh attempts to swing across the line. He gets the top edge which goes straight up and is caught by the keeper.
Voges plays a clever reverse sweep and is rewarded with another boundary. This partnership is started well and will look to press on, as McCullum's spell comes to an end.
Marsh gets a top edge and is rewarded with a streaky boundary. He then plays a cover drive and picks up another four runs. The gap between balls faced and runs scored has now closed.
The first choice off-spinner is starting to get the ball to grip and turn. A rare short delivery is delt with as Marsh pulls for a boundary.
Willianson is doing a wonderful job. Every over that he gets through is an over than the seamers won't have to bowl later in the innings.
McCullum continues as two off-spinners defend the powerplay. A sloppy over-throw gifts another run to Voges. Marsh eats up a few dot balls, but if he gets it, he can hit a long ball.
Marsh, the new man to the crease, is welcomed by the batting powerplay. Williamson continues, even in the powerplay. Pressure is being applied to the new batsman in the form of a silly-point. A great start to the powerplay for the Black Caps only costs them one run.
McCullum comes back into the attack and continues the threat of spin. Good rotation of the strikes takes Australia past 150 and brings up Voges 50. WICKET. Bailey walks across his stumps and is bowled behind his legs.
Vettori completes a wonderful spell. it is probably a good thing for Australia that he isn't 100% or who who's what kind of damage he could have caused. Going for just 23 runs off his 10 overs, he has done his bit for the team.
The part-timer backs up his ex-captain by bowling a good over. The batsmen aren't taking any risks and may be thinking about the batting powerplay.
Vetorri comes back into the attack to bowl is last two overs and try to hault the rate of scoring. The crafty spinners does the job straight away. New Zealand needed that maiden because this partnership is threatening to take this game away from them.
The part-time spin of Williamson is proving much harder to get away than the front-line seamers.
The left-arm seamer strays onto the pads and is glanced for a boundary by Voges. The dose is repeated and to make matters worse, it is a no-ball. A poor over adds to Australia's momentum.
Williamson comes into the attack to try and get some more overs of spin in. He will probably be helping Southee to complete the required 10 overs. A sweep for two brings up a second consecutive 50 for the captain.
The ball is making a cracking sound as hit hits the bat. The quick bowlers are extracting very little movement and need to be targeted. Voges cashes in as it is his turn to hit a drive down the ground. Southee remains too full and this time is dispatched through cover.
McCleneghan is brought back into the attack.He always gets a little bit out of the wicket and immediately gives the batsman something to think about. A lovely straight drive beats the fielders this time and adds four to the total.
A leg-bye brings up the 100 for the Aussies. Some wonderful cricket see's a straight drive that desrved four, brilliantly fielded by a diving McCullum.
McCullum is let down in the outfield, the first mistake by the Black Caps in the field. It results in an easy two where there should have been one at the most. Its small margins that separates teams at this.
Southee comes back into the attack. The batsmen will not be unhappy to get a little more pace to work will. It is still early days, but a score of 250 looks like it will be tough to chase.
McCullum tries his version of the one that goes the other way. It is not very well disguised though and is easily worked for a single.
Vettori is flying through his spell and has given away very little. It can be expected that the old lad will be rewarded with a spot in the shade of the change room after his 10 overs are done.
New Zealand seem be be in control as the suffocation of the Australian middle order continues. There isn't a great deal of turn, but the batsmen are very tentative.
The wiley Vettori gives Bailey a single and new attacks the new man, Voges. He eats up a string of dot balls before geing given one off the last ball to retain the strike.
Some tight bowling combined with athletic fielding in the ring is making run scoring a very difficult business. WICKET. The pressure has told as Wade is out lbw. He has called for the review. The decision stands and Wade is McCullum's first victim.
The two spinners opperating in tandum with start a very important part of this innings. New Zealand will look to strangle the run rate and create wicket taking chances through pressure. Australia on the other hand will look to turn over the strike and keep wickets in hand for an onslaught later in the innings.
Wade runs down the wicket and beats mid-on with a swing across the line. It's a very risky shot but he will be happy with the result. Even with the boundary, just five come off the over.
Vettori continues to make life difficult as he mixes up his pace well. A quicker ball nearly squeezes through Bailey's defence. A wonderful over takes the players to drinks.
McCullum comes into the attack to bowl some off-breaks. The skipper's brother does a good job and should get a long spell in these conditions.
Bailey has found is confidence and is now using his feet to the spinner. The experienced bowler does well to adjust his length though and no real damage in inflicted.
Southee comes into the attack and over-pitches while looking for some swing. Bailey capitalises and drives straight back past the bowler for four. The run rate is starting to move in the right direction for the Australians. Bailey repeats the dose to round off a poor start to Southee's spell.
The wiley left-arm spinner is taking all the pace off the ball on this slow pitch and is getting a nice loop. Vettori has always had a good cricket brain and he understands that it will be difficult for the batsman to make the pace on this dry deck. The over is ruined with a boundary off the last delivery.
The end of the powerplay, and the resulting fielding changes, should allow the chance for the strike to be rotated more frequently. The batsmen take advantage as they tick the scoreboard over nicely.
Vettori ends the first powerplay with another quality over. The batsmen are show some urgency and manage to collect four runs.
Wade tries to transer the pressure as he attempts to pull a Mills delivery which isn't short enough. He is struck in the mid-chips, but shakes off the pain and collects a single so that he can rethink his plan from the bowler's end.
Mr experience, Dan Vettori comes into the attack. He extracts some turn from the dry pitch, even with the new ball. His accuracy means that just two runs come from his first over.
Wade survives a wonder over from Mills. It included everything except the wicket. Multiple plays and misses, but no edge it found. The bowler gets a maiden as a slight reward.
The left-arm bowler is using the natural angle to his advantage against the new batsman, Bailey. The Aussie skipper gets off the mark and then the strike is rotated well by the two in the middle.
Mills drops slightly short and a picture perfect back-foot drives results in Wade's first boundary. Another one is dragged down and is pulled powerfully for four. The Australian's are the best in the world at cross-bat shots, so the bowlers need to be right up to the bat.
WICKET. The pressure makes the batsman look for a quick single that isn't there. Guptil swoops on the ball and a direct hit see's the back of Hughes. The bowler over-steps, which will allow Wade a free-hit. A slow yorker is produces and the free-hit produces no runs. A missed opportunity for the batsmen to get going.
Mills will be excited by the early wicket, as he now has two left-handed batsmen to bowl at. Immediately he goes past Wades outside edge and the Black Caps are buzzing in the field. Wade gets off the mark as he nudges a single down to third-man. That should calm him down after looking out of his depth early doors.
McClenaghan shares the new ball. The left-arm seamer has been a wonderful find for New Zealand as he has developed a habit of taking early wickets. Watson shows his class by playing a pleasing straight drive resulting in the first boundary of the day. WICKET. The bowler fixes his length and he has grabbed an early wicket once again. The big fish, Watson is caught behind by fellow Australian (originally) Ronchi.
Mills opens the bowling the New Zealand. He took a wicket off the first ball of their last match. Watson misses out as he firmly punches consecutive deliveries off his pads to fields on the leg-side.
The sky is overcast, but batting first is the way to go. It is the same wicket that was used for the Pakistan vs South Africa match and should therefore start to turn especially in the second innings. Both teams have read the pitch the same way as Australia bring in another spinner in the form of Doherty and New Zealand have retained the slightly tender Vettori. The best time for scoring will be against the new, hard ball and at the death if the batting team has wickets in hand. The spinners will however strangle the middle overs, which will be a test for the batsman.
Shane Watson, Matthew Wade, Phil Hughes, George Bailey, Adam Voges, Glenn Maxwell, Mitchell Marsh, James Faulkner, Mitchell Johnson, Clint McKay, Xavier Doherty.
Luke Ronchi, Martin Guptill, Kane Williamson, Ross Taylor, Brendon McCullum, James Franklin, Nathan McCullum, Daniel Vettori, Tim Southee, Kyle Mills, Mitchell McClenaghan.
George Bailey triumphs in the flip of the coin and Australia will bat first. Bailey says spinner Xavier Doherty has replaced Mitchell Starc - and all-rounder Glenn Maxwell is in for naughty Warner. Vettori, after all, is fine - so New Zealand's XI is unchanged.
Australia, again, will be without Michael Clarke, who is nursing a back injury. David Warner, too, will miss this match - after an alleged altercation with an English player (Joe Root, reportedly) recently. No Daniel Vettori for New Zealand - he is still tending to an Achilles heel niggle.
The Black Caps will be all but guaranteed of a place in the final four if they win today - thanks largely to their victory over the West Indies recently. The Aussies, meanwhile, will be pretty much knocked out of the competition if they lose - in the wake of defeat to England last week.
