As well as diving, Malhotra body-boarded on sand dunes, learned to do the haka at the Waitangi treaty grounds, visited Cape Reinga and Tane Mahuta and cooked seafood.
He also appears to be an All Blacks convert, tweeting "good luck to NZ for today's match v France" ahead of Sunday's quarter final.
"I have seen the haka before during the All Blacks rugby matches. It gives strength and power to the players before their games. It is highly inspiring and I am glad I got to try my hands at it," Malhotra said.

"As soon as you set foot in the forest you know that you are in a special place with a lot of history and culture," Malhotra said.
"To top it all, the pounamu given tome was absolutely beautiful. I know how much this stone means to the Maori people, I will treasure and cherish it forever."
