They are found throughout the country, particularly in the North and South Islands, but are most common in moist, temperate forests. You can find them growing in a range of habitats, including:

* Rainforests: Silver tree ferns thrive in the shady, humid conditions of New Zealand's rainforests.

* Bush areas: They are also common in bush areas, particularly along streams and rivers.

* Gardens: Due to their beauty, they are popular ornamental plants and are commonly cultivated in gardens throughout New Zealand and other temperate climates.

While the Silver tree fern is primarily found in New Zealand, it can also be found in other parts of the world where the climate is suitable, including Australia, Tasmania, and the United Kingdom.
