The shocking 0-4 drubbing at the hands of Bangladesh on Sunday pushed New Zealand to the seventh spot behind Pakistan in the latest ICC one-day rankings issued in Dubai.
On the other hand, the upset series triumph helped Bangladesh earn 13 rating points but the team remained ninth alongside the West Indies.
Bangladesh are still placed behind the Caribbean side when the ratings are calculated beyond the decimal point. The West Indies have 67.06 ratings points while Bangladesh have 66.68 ratings points.
Bangladesh had started the series on 53 rating points.
New Zealand has plummeted to 96 ratings points after starting the series on 112.
Bangladesh next host Zimbabwe in a five-match ODI series from 1-15 December and can aim the number-eight position as the West Indies will play five ODIs against Sri Lanka from December 9.
Meanwhile, the abandonment of the first ODI between India and Australia in Kochi on Sunday has given South Africa a chance to briefly move into second place on the championship table.
For this to happen, they will have to beat Zimbabwe in the second ODI in Potchefstroom.
However, if they lose the match, the Proteas will drop to as low as fifth -- one point behind fourth-placed England.
