Kane Williamson, the New Zealand captain top-scored with exactly 100 after winning the toss in a match reduced by rain to 46 overs per side. The captain struck eight fours and three sixes by the time he was run out with 6.5 overs remaining.
The 24-year-old made his worldwide debut in 2011, yet the fact he's played just three Tests and 28 one-day internationals since then is testament to how much time Cummins has spent on the treatment table.
The bowling for Australia revolved around one man. Josh Hazlewood was scintillating as he took six for 52 in nine overs.
The Black Caps pool also features hosts and tournament favourites England and Bangladesh. Jose Mourinho might settle for a solitary point against a close rival but in cricket's Champions Trophy any such hiccup can help others in the group and England now have only to win one of their next two games to qualify for the semi-finals.
"I think if we look back at the last MoU, players gave back $10 million to grassroots cricket, which is quite significant", Smith said. The two teams had played out a draw at the same venue in the last edition of the Champions Trophy, and there is no doubting which side would have been the happier one when this Group A game was abandoned.
With the Chappell-Hadlee Trophy on offer, both Australia and New Zealand will be keen to grab the award and move further into the Champions Trophy with momentum on their side.
However, his run out was the first of seven wickets to go down in just 5.5 overs as New Zealand crumbled. "So we probably won't end up going with the four big quicks to begin the series".
And when Henriques was caught and bowled by Adam Milne, Australia were three down.
With a couple of high quality pace bowling all-rounders in Marcus Stoinis and John Hastings in their ranks, the Australia bowling line=up could prove hard to handle in the swing friendly English conditions.
Williamson fell soon after to a careless run-out, and Neil Broom followed for an ineffectual 14 from 18 balls as New Zealand threatened to lose some momentum, especially with Cummins returning to rattle helmets and deposit batsmen on their backsides.
Hazlewood clinched the wickets of Adam Milne, Mitchell Santner and Trent Boult in the 45th over to bring the curtains down on the New Zealand innings.
Smith criticised his seamers for "one of the worst bowling displays that we've put on for a very long time", as New Zealand amassed 254 for three at the end of the 39th over. Williamson was joined by Ross Taylor and there was a mid-innings lull as the batsmen attempted to set a platform for a total above 300. Smith will spearhead the middle-order, expected to be supported by the likes of Glenn Maxwell and Moises Henriques.
The cricketing rivalry between Australia and New Zealand is ranked as one of the toughest battles in worldwide cricket.
