A year on, they're back in the country for yet another ODI and T20I series.
The Kiwi skipper spoke of how his team was bracing itself to face a lot of slow bowling.
In that previous series, MS Dhoni was still the leader of India's One-Day side - it was his last series as India captain - and Anil Kumble was the head coach.
Cut to date. Virat Kohli has taken over the reigns of Indian cricket completely, with Ravi Shastri in tow as the chief coach.
Williamson is aware of the effect of Yadav and Chahal in Indian conditions and it was one reason he had kept his eye on the India-Australia series.
Williamson at 27 has already played 214 internationals comprising 61 Test matches, 114 ODIs and 39 Twenty20 matches. █ █ Kane not surprised by Pandya's evolution Hardik Pandya is a vital cog lending balance to the Indian squad, says Kane Williamson. We played some good cricket, but I don't think it was a complete performance. "It was disappointing. It's nice to be back here again and the guys are looking forward to the tour". You're required to adapt from ground to ground. We saw it in the IPL. At times you've seen a series with scores of 350 or 380, and at other times you've seen a winning score being 250. Being flexible with your approach is very important. You have dew factor and you had a number of things that came into it. "So, it is important that you have flexibility, adapt well".
Part of that adaptation factor will come against Kuldeep and Chahal, the spin duo which has bamboozled the Aussies with its craft. Some of them even played in the same team. We know it will be a tough challenge, but one that guys are looking forward to. "It's not too many Chinaman bowlers going around and those coming in have all been fairly successful. It's a challenge that the guys are looking forward to", said Williamson referring to Kuldeep. Part of the adapting to the surface and conditions is also the climate that you're in. "So it is important that we remain flexible and adapt well", said the Kiwi skipper. The New Zealanders do not want to take too much baggage from past results. It's impossible for everyone to play all formats all the time because the schedule is so dense.
"But you always know that the team India will put out will be very strong".
It was precisely a year ago that New Zealand made their last trip to India. "Now, we're seeing him come along with the bat and making contributions that any team would be pretty happy to have from their all-rounder", said Williamson ahead of the limited over series against the hosts.
Williamson's team will be playing a first global in almost four month's time against India at the Wankhede Stadium on October 22 and the small group - majority of whom have played the IPL - must be happy that they were able to make a good start to their preparations for the 17-day series involving three ODIs and as many Twenty20 internationals.
"He's a very vital player for India.to have a fast bowling all-rounder that bowls good pace and hits it out of the park is always exciting to have", added Williamson.
