KEY POINTS:
As wakeup calls go, this one just about takes the biscuit.
New Zealand went into their opening match of what will be a lengthy summer under-prepared, over-confident and got done by Bangladesh.
There should be no complaints about the seven-wicket loss. Bangladesh did have the better of the bowling conditions and used them well. Put that into the mix alongside some ordinary, undisciplined batting and less than inspired bowling and this is what you get.
Daniel Vettori and Brendon McCullum will be fuming, on at least two counts.
First, they'll have known that a 3-0 win would have bumped New Zealand up to second on the ODI world rankings behind Australia, whom they play in February in what would have been a terrific series. It could still be, but without that 1 vs 2 element.
I still believe New Zealand deserve to be ranked second or third based on what we've seen in the past few seasons, but even if they win the series 2-1, which they should do with this rough start out of the way, it won't do the trick on the rankings list.
And secondly, they'd be embarrassed at turning in a half-arsed performance when they'd have wanted to hit the ground running. They'll know there will be teams around the world chuckling at their slip-up, and that will sting.
But if you don't have any preparation to speak of, this is how teams can come unstuck. Some players were in India with New Zealand A and should have been match ready. It didn't show.
They'll deny it, but it is easy to imagine New Zealand went into the match expecting a comfortable 3-nil stroll in the series. The mindset was wrong. All the pre-tour speculation had this trip down as a soft lead-in to the two tests in Australia.
But Bangladesh might have read the previews too, and they were smart.
They bowled wicket to wicket, took the pace off the ball, ran hard in the field and had one batsman, opener Junaid Siddique, who was prepared to be patient, work the ball about to keep the runs ticking over - remembering they were only chasing four an over, therefore didn't need to chance their arm - and got his fair reward.
New Zealand teams tend not to start a summer in full stride. They need some meaningful cricket under their belt. Even so, they still expect to at least be competitive. My pick is they won't really get going until the two-test series starts next Friday.
New Zealand will be too good in the tests, but one-day cricket is a different beast. You can get two teams who appear mismatched, but if the superior side are off their game and the supposed weaker team play to their optimum the gap between the two is significantly reduced.
My money will be on a victory at the same ground today and the series wrapped up in Chittagong on Tuesday.
But Bangladesh have done themselves proud and the result is good for the international game.
Vettori and co won't see it that way but the newest test nation are chipping away at the established countries.
If their five-day prowess is still limited, they are showing they are learning the ODI lessons, and New Zealand have just had a sharp reminder of that.
