Yadav and Chahal combined to pick up 13 wickets in India's recent 4-1 ODI series victory over Australia.
"We need to find our best bowling combination before we reach the World Cup (in 2019) stage," Kohli told reporters on Saturday.
"We always had in mind to bring wrist spinners into play. We honestly did not think of playing the two together but they are so good together, it is tempting to play them in every game.
"Ashwin and Jadeja have played limited-overs cricket for last six-seven years regularly. These youngsters have stepped up and it creates a strong pool for us before the World Cup."
New Zealand skipper Kane Williamson believes his side face an uphill task to beat India in their own backyard.
India hold a dominant record in bilateral ODI series at home, having lost just two out of 16 played since their defeat by Australia in 2009-10.
Last year, the Kiwis forced a decider on Indian soil but the hosts recorded a convincing 190-run victory in the final Visakhapatnam ODI to claim the series 3-2.
"India's record is very good at home. They are a very hard team to beat. We know that, at home in particular, they are the strongest team in the world," Williamson said.
"People talk a lot about adjusting to the conditions in India, and that's is really important. We did that fairly well last time we were here and it would nice to do that better (this time)."
