During the winter the weather can range from 14 Fahrenheit to 52 in the summer. This island has an average of 115cm. of rainfall a year

add The geographic range of forests covers the whole country, apart from a few dry or desert areas.

Central Otago used to be forested, but fires coincident with the arrival of the Maori destroyed the forest cover over perhaps half the province. This is well dated by C14 techniques.

Unfortunately, the forest concerned can survive down to 200 mm of rainfall, but it needs about 400 mm for a new forest to establish. Thus in the drier periods, somewhat after the local ice ages, the forest could not re-establish.

In the North Island there were two significant desert areas, one near Waiouru, and the other in Kiangaroa to the east. These were desert because of volcanic ash fall. The Kaingaroa Desert has subsequently been planted out in coniferous forest.
