Mount Herbert / Te Ahu Pātiki is, at 919 metres (3,015 ft), the highest peak on Banks Peninsula, New Zealand.^[1] It is south of Lyttelton Harbour with the township of Diamond Harbour at its northern foot.

The peak is named after Sidney Herbert, a member of the Canterbury Association.^[2] The official name of the peak was amended to become a dual name by the Ngāi Tahu Claims Settlement Act 1998.^[3]

In the 1860s, the mountain gave its name to a general electorate for some years. In the 1865 electoral redistribution, the Mount Herbert electorate was formed; it was first used in the 1866 election. In the 1870 electoral redistribution, the electorate was abolished.^[4]

According to the Köppen Climate Classification, Mount Herbert is a dry subpolar oceanic climate, with slightly more precipitation in the winter than in the summer.
