Mount Taranaki, or Mount Egmont, is an active but quiescent stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. Although the mountain is more commonly referred to as Taranaki, it has two official names under the alternative names policy of the New Zealand Geographic Board. The 2,518 metres (8,261 ft) mountain is one of the most symmetrical volcanic cones in the world. For many centuries the mountain was called Taranaki by Māori. The Māori word tara means mountain peak, and naki is thought to come from ngaki, meaning "shining", a reference to the snow-clad winter nature of the upper slopes. It was also named Pukehaupapa and Pukeonaki by iwi who live in the region in ancient times. In 1881, a circular area with a radius of six miles (9.6 km) from the summit was protected as a Forest Reserve. Areas encompassing the older volcanic remnants of Pouakai and Kaitake were later added to the reserve and in 1900 all this land was gazetted as Egmont National Park, the second national park in New Zealand. With intensively-farmed dairy pasture reaching right up to the mostly-circular park boundary, the change in vegetation is sharply delineated in satellite images. There are parts of the national Park where old growth forests are found.
