World Cup Super 8, Grenada: Australia 348-6 beat New Zealand 133 all out by 215 runs
Matthew Hayden's bat has produced a glut of boundaries
Australia continued their ominous form to beat New Zealand by 215 runs in the final Super 8 match for both teams.
Matthew Hayden's 103 made him the third batsman to hit three centuries in a single World Cup as the Aussies won the toss and hit 348-6 in Grenada.
Hayden also went up to 580 runs for the tournament, just 93 runs behind Sachin Tendulkar's 2003 World Cup record.
Brad Hogg's 4-29 saw the Kiwis bowled out for 133 in the 26th over, with Peter Fulton last man out for 62.
There was no obvious need for either team to win the match.
It was already clear before the contest began that Australia would play South Africa in the St Lucia semi-final, with New Zealand facing Sri Lanka in Jamaica.
But Australia had a score to settle after being humbled 3-0 in a one-day series in New Zealand in February.
And they also wanted to keep their unbeaten run in World Cups, stretching back to the middle stages of the 1999 tournament.
Their life was made considerably easier by the absence of New Zealand speedster Shane Bond, who was ruled out of the match with a stomach virus.
Ricky Ponting won the toss and elected to bat first in the final contest of the tournament in Grenada.
The seventh ball of the innings ballooned off Adam Gilchrist's bat to third man, but progress was smooth thereafter.
Hayden and Ponting (66) put on 137 off 131 balls, forcing the second powerplay to be delayed until the 24th over - when the Aussie skipper was caught at mid-wicket off Jeetan Patel.
Michael Clarke plundered three off-side boundaries off a Mark Gillespie over before Hayden cut loose in similar fashion off Daniel Vettori.
Finally, Hayden was caught and bowled by Scott Styris, Clarke (49) was bowled by a James Franklin delivery and Patel grabbed a second wicket from the first ball of the 41st over when he had Andrew Symonds caught at long-off.
Aussie fans helped swell an overall attendance of 12,249
That made it 257-5 and Patel continued to bowl tidily to finish with 2-48.
But Shane Watson, on his return from injury, clobbered Gillespie for two sixes and two fours in the 48th over to finish with 65 from 32 balls.
He and Michael Hussey (37) put on a breezy 77 over the closing overs.
New Zealand had successfully chased 347 to win in Hamilton in February, but on a wicket beginning to slow up and taking turn, this was a different prospect.
As soon as Stephen Fleming was wrongly given out caught in the fourth over - the ball deflected off his shoulder rather than bat or glove - there was an air of inevitability about the outcome.
The Kiwis went for their shots but it meant Glenn McGrath was more or less gifted a couple of wickets, including the in-form Styris for 27.
The veteran seamer extended his record World Cup wicket tally to 67 and needs just one more to match Chaminda Vaas' 2003 haul of 23 in a single tournament.
Hogg enjoyed the surface and grabbed three lower-order wickets, while Shaun Tait continued his excellent World Cup with 3-32.
