In what was a rematch of last year's final, the Black Caps defeated the hosts by an enormous margin of 89 runs at the Sydney Cricket Ground.

Devon Conway was the driving force for New Zealand as he scored an unbeaten 92 from 58 deliveries.

He was also involved in an opening stand of 56 runs in just four overs alongside team-mate Fin Allen before the Kiwis ended their innings on a total of 200 for three.

Australia were expected to put up a respectable chase on a good batting surface but they were outclassed by the fielding side who dismissed them for 111 with 17 balls remaining.

Glenn Maxwell and Pat Cummins were the only players who went past 20 in the Australian innings, with scores of 28 and 21, respectively.

The second fixture of the day saw England take on Afghanistan at the Optus Stadium in Perth.

Sam Curran produced a memorable performance with the ball as he took five wickets to help his side skittle Afghanistan, who were all out for 112.

England's chase got off to a steady start with Alex Hales and Jos Buttler putting on an opening partnership of 35 runs.

They suffered a brief scare midway through the innings, losing four wickets for 46 runs.

However, Liam Livingstone stepped up to score an unbeaten 29 runs from 21 deliveries to see England across the line.

New Zealand and England are level on two points apiece but the former's net run rate of 4.450 sees them take pole position in Group 1, in front of England.

Competition is set to continue tomorrow with Ireland facing Sri Lanka in Group 1 in Hobart, while India and Pakistan play in the eagerly-anticipated Group 2 opener in Melbourne.
