What a performance. They have thrashed Australia. That is a mighty effort.

There is some soul searching to do for the Australians. The tournament isn't over but they are going to have to improve their performances. Their next match is an absolute crucial match.
New Zealand win by 89 runs
Cummins c Conway b Southee 21 (Aus 111 all out)
And that is that.
New Zealand have hammered hosts and defending champions Australia in the opening game of the World Cup.
An 89-run margin is an absolute mauling.
Pat Cummins skies Tim Southee into the gloves of Devon Conway to complete the rout.
A Kiwi win is no surprise, but who saw this thrashing coming?
Aus 111-9
Target 201
This is on course to be Australia's biggest T20 loss in terms of runs to New Zealand and against allcomers in a World Cup match. Quite the shallacking.

Trent Boult was too smart. The old knuckle ball. He's bringing out all the party tricks.

Two in two!
A swipe from Adam Zampa sees his furniture rearranged. Trent Boult on a hat-trick to finish the match....
WICKET
Starc b Boult 4 (Aus 109-8)
Trent Boult wins the battle of the left-armers. Mitchell Starc swings at Boult and has his stumps splattered.

Phillips has been very good in the field. We saw a big superman dive earlier. I'm very impressed with him.
Aus 109-7

Just for the record, Ferguson is bowling at about 90mph. Imagine how quick he would be without a moustache to slow him down.

Pat Cummins is still giving it some humpty. Ferguson has been whalloped over mid-wicket for a maximum.

The story out of this is the brilliant performance from New Zealand.
Aus 97-7
Target 201
Australia won't have long to pick themselves up from this. They have to make the long trip to Perth to play Sri Lanka on Tuesday. All of a sudden, that is a must-win.
Aus 94-7
Target 201
This match is continuing, but the contest is done. It's just how these two teams can alter their net run-rate. England's game against Afghanistan is less than an hour away.

The Australians have been outplayed in bat and ball by New Zealand in their opening game.
Aus 91-7
Target 201
Mitchell Starc is the new man. Earlier this week I saw Aussie coach Andrew McDonald touting him as a reserve wicketkeeper, probably because he could get some tips from wife Alyssa Healy.

They then backed that up with some stunning catch and dead-eye bowling.
The Aussie were skittled for just 111.

I wonder what England will make of that? Across Australia, in Perth, they are about to start their campaign against Afghanistan.
