The range includes a number of summits between 300 and 500 metres above sea level. The range is of significant geological, environmental and scenic importance.

History

The volcano is one of two from which Banks Peninsula was originally formed 12 million years ago. The area was first populated by Māori during the 14th century. During early European settlement some 500 years later the Port Hills presented a challenging barrier between the harbour and the planned settlement of Christchurch, their steepness and ruggedness making access extremely difficult. For many years the majority of settlers used the precipitous

and a separate rail tunnel connect the port and the city suburbs, and three road routes crossing the range – via Evans, Dyers and Gebbies passes – are connected by the Summit Road. In February 2017, bush fires in the Port Hills burned for days, destroying over 2000 Ha of bush and several homes.

Geography and conservation

The Port Hills are a prominent feature of the central Canterbury landscape, being visible for many kilometres from the north and west. The crest of the Port Hills varies somewhat in height, being lowest at the eastern (seaward) end. Two road passes traverse the Port Hills from Christchurch. Dyers Pass (elevation c. 330 m), almost due south of central Christchurch is the more prominent of the two passes. Evans Pass (elevation c. 200 m), which is near the eastern end of the Port Hills, normally connects

West of Dyers Pass, the Port Hills curve away southward and become even higher, rising to 573 m at Coopers Knob. From Coopers Knob the crater rim descends to Gebbies Pass (elevation c. 160 m). The hills south and east of Gebbies Pass are regarded as part of Banks Peninsula proper rather than the Port Hills. Several suburbs of Christchurch extend onto the northern slopes of the Port Hills, including Cashmere, Mt Pleasant,

Other parts of the hills are used for farming and forestry, as well as a significant number of scenic reserves created for recreational and conservation purposes, following an initiative by Christchurch councillor Harry Ell at the turn of the 20th century. In 1948 the Summit Road Scenic Society was formed to continue development and maintenance of the reserves. The hills are an important recreation area for Christchurch residents, with several public parks and reserves, including tracks for
