Mount Cavendish, Mountain summit in Port Hills, Christchurch, New Zealand.

Mount Cavendish is a summit in the Port Hills near Christchurch that rises 448 meters above sea level. It forms part of the crater wall of an extinct volcano responsible for creating Lyttelton Harbour.

The Morten Brothers transferred the land to the Crown as a scenic reserve in 1910. In 1912 Harry Ell named the peak Hill Morten to honour the family's gifts for the Summit Road and reserves. The name Mount Cavendish, first applied to nearby Mount Pleasant in 1848, was later transferred to this peak after the Hon. Richard Cavendish of the Canterbury Association.

The peak's name honours the Hon. Richard Cavendish of the Canterbury Association, though the title was first applied in 1848 to today's Mount Pleasant and only later moved to this summit. The Morten Brothers transferred the land to the Crown as a scenic reserve in 1910, and Harry Ell named the peak Hill Morten in 1912 for the family's gifts along the Summit Road.

Visitors can reach the summit by taking the Christchurch Gondola or walking trails such as the Crater Rim Walkway. The site is accessible year-round, though weather conditions can change quickly and affect visibility.

Visitors can see ancient lava flows on the mountain that are clearly visible and thousands of years old. These geological formations rank among the finest examples of volcanic activity preserved in this landscape.
