Aurora borealis are easier to spot because places like Scandinavia, Iceland, and Alaska are above 60°N and they’re relatively easy to visit. It is very rare to see auroras outside these polar latitudes.

New Zealand and Patagonia, the southernmost inhabited places, only reach about 50° and 56°S respectively. These regions are extremely remote and difficult to travel to, and conditions are always less than ideal. The only place you can reliably see aurora australis is Antarctica, which is pretty much inaccessible.
