New Zealand in the future


When it comes to the geography of an area we know that over time it changes. Areas go from an aquatic area with many marine animals and fish to an arid desert, or vice versa. There are many factors that can change the geography of an area over the course of time. So with that in mind we can speculate into the future of New Zealand, we can look at various possibilities on new formations and erosions processes that will change the land many years from now.

It is no secret that New Zealand over the past millions and billions of years has formed and shaped. Every piece of land that is visible now at one point either was not there or drifted from its original spot, New Zealand is no different. It being an island means it either broke off of a bigger land mass and drifted away due to plate tectonics or that it was created by under -water volcanoes and hot-spot migration. It is generally believed that New Zealand broke off a larger section of land and drifted (www.teara.govt.nz). 

That being said in the future New Zealand will continue to drift, as will all land masses, that is just how plate tectonics work. It will most likely collide with another continent. This will create an opportunity to create new mountains when the two land masses collide, one part of land will fold under the other part. The creation of new geographical formations does not stop there. Many of the rivers on the South Island are braided rivers, and are very thin, in many years’ time it is possible that these small rivers could dry up, possibly creating a more dry and arid landscape than what we see now. Meandering rivers could eventually erode away existing formations and create a large lake, or they could dry up and create a desert. There are many possibilities the future holds.

An interesting possibility to consider is what if an earthquake or another natural disaster greatly alters the landscape? Earthquakes have great force and can be devastating to the land; a seismic quake could easily tear one or both of the islands apart. New Zealand is part of the Pacific Ring of fire and more than 20,000 earthquakes occur each year(Wikipedia.org), although most of them are fairly tiny. Over time this can add up, also it is possible that a giant one would happen and greatly impact the islands. How the islands are impacted could vary, it would no doubt hurt many people, that is, if we are still around hundreds of thousands or millions of years from now.

We have heard a lot about global climate change and the melting of polar ice. If that is true and all (or most) of Earth’s ice melts then a lot of islands (including New Zealand) will most likely be under water. Most of the land we see today could be beneath the ocean if ice continues to melt at the rate it is currently melting at.


There is no definite ways of knowing for sure just how New Zealand will be impacted in the future. All we can do is make educated guesses and speculate based on the past and the current information we have available to us. The only thing that is for certain is that things will change and the world will look very different in a million years, if only we could be around to see how different.
