The teenager from Pune completed the feat in eight hours and 37 minutes.
Starting from the North Island in temperatures of around 19 degrees Celsius, More battled inclement weather and a sudden drop in temperature to complete the task.
With this feat, More became the ninth person in the world to complete the Ocean's Seven marathon.
The Ocean's Seven consists of seven long-distance open-water swims, which includes the North Channel, the Cook Strait, the Molokai Channel, the English Channel, the Catalina Channel, the Tsugaru Strait and the Strait of Gibraltar.
