Despite the Black Caps' edge in the ICC one day rankings the New Zealand cricket captain reckons the upcoming series with the West Indies will be close.
After squaring the Test and Twenty 20 instalments of the Windies tour the two teams now head for Queenstown and Wednesday's opening one dayer.
New Zealand are ranked three places above the West Indies in the one day rankings but Vettori says the tour so far indicates there's little separating them.
Vettori's men can climb one place to fourth in the ICC ODI Championship table but could drop to as low as eighth after the series.
They currently sit in fifth place on 113 ratings points and a 5-0 series win will put New Zealand ahead of Pakistan in fourth place on 118 points. A 4-1 series win will also be enough for the Black Caps to improve upon their current standing.
However, if the 5-0 series result goes the other way, New Zealand will concede 11 ratings points and the West Indies will gain 11 points, putting both teams level on 102 ratings points.
In that event, Chris Gayle's side would be placed higher than the Black Caps in seventh place when ratings are calculated beyond the decimal point.
