The South Island of New Zealand is part of New Zealand.

The South Island of New Zealand is one of the two main islands that make up New Zealand. It is located in the south of New Zealand, separated from the North Island by the Cook Strait to the north, facing Stewart Island across the Foveaux Strait to the south. It is 1600 kilometers west of Australia and borders Tonga and Fiji to the east. The South Island coastline is 6,900 kilometers long and has many beautiful beaches. From Cape Farewell in the north to Bluff in the south, it is 840 kilometers apart, and the widest east-west distance is 336 kilometers. The total area of the island is 154,037 square kilometers, making it the largest island in New Zealand and the twelfth largest island in the world. The Southern Alps on the west coast of the South Island are the largest mountainous area in New Zealand, with Mount Cook being the highest peak at 3,754 meters above sea level. There are narrow plains along the eastern coast, with the Canterbury Plains being the most important. In Maori, the South Island is called "Te Wai Pounamu", which means "greenstone water" in Chinese.
