The Black Caps are about to spin the selection wheel after their drubbing in the final one day match in India.
But it was going to happen anyway, according to coach Mike Hesson, as they look ahead to the the 2019 World Cup in England and Wales.
Hesson described the 190-run defeat in the deciding match at Visakhapatnam as "a huge step backwards" although he emphasised how hard it is to win any form of cricket series in India.
"We lost over 1000 matches from our World Cup squad - we have got 36 ODIs coming up and we will try some different players," he told the Radio Sport Breakfast.
"It will be similar to the last World Cup where we will look at a lot of different players then pull them all together towards the end."

Hesson said New Zealand had depth, but not when it came to competing in India which was an issue they needed to address.
"We need to replace five or six key players and have been able to blood some new ones - Tom Latham and Mitchell Santner in particular have shown they are good enough.
"We won two of our last three games which suggests we did get better but last night was very, very frustrating. We have spent time dwelling on it, making sure that sort of thing doesn't happen again."
New Zealand scored just 79 in the final innings of the five-match one day series.
Hesson said: "When things went bad we made some very, very poor decisions. We expect more of the new players as well as the experienced players in those situations
"But the reality is, every team struggles in India whether they are from the sub continent or not. They are incredibly difficult to beat at home."
Kane Williamson's side begins a two test series against Pakistan - ranked number two behind India - in Christchurch on November 17, followed by three one dayers in Australia. Bangladesh, who have just beaten England in a test for the first time, begin their tour with a one day match in Christchurch on Boxing Day.
