The following are lists of mountains in New Zealand ordered by height. Names, heights, topographic prominence and isolation, and coordinates were extracted from the official Land Information New Zealand (LINZ) Topo50 topographic maps at the interactive topographic map of New Zealand site.
All summits over 2,900 m are within the Southern Alps, a chain that forms the backbone of the South Island, and all but one (Mount Aspiring) are within a 10-mile radius of Aoraki / Mount Cook. Some of these summits are mere shoulders on the ridges of Aoraki and Mount Tasman.
These are all the mountains over 2,400 m with a topographic prominence (drop) of at least 300 m (985 ft), closely matching those on the list of mountains of New Zealand by the New Zealand Alpine Club. Five peaks overlooked on that list are indicated with an asterisk. Of these 100 mountains, all but two — Ruapehu (Tahurangi Peak) (19th highest) and Mount Taranaki / Egmont (65th highest) — are in the South Island. Tapuae-o-Uenuku, in the Kaikoura Ranges, is the highest peak outside the Southern Alps.
