New Zealand captain Brendon McCullum admitted his side were not as sharp as expected despite going into their Champions Trophy Group A match against Australia as marginal favourites.
Australia posted a score of 243-8 after winning the toss and opting to bat first at Edgbaston.
But with their opponents having reached 51-2 in reply the match had to be abandoned as a no result with the Black Caps only able to complete 15 overs of their innings.
"We were confident heading in," said McCullum.
"While Australia may not be the great team it once was, it's a very good cricket team and it's got match-winners throughout the line-up.
"We prepared well and planned well but maybe didn't execute as well as we could have with.
"But I thought we did an okay job with ball in hand and had two very good batsmen in Ross (Taylor) and Kane (Williamson) at the crease.
"We definitely would have preferred a full game but we'll take a point and know we're one good performance away from the semi-finals."
