Abstract: The presence of periglacial phenomena and activity in New Zealand is controlled primarily by altitude, especially as modified by topography and lithology. Thus, the alpine‐type mountains that form the backbone of the South Island (Southern Alps) show little in the way of patterned ground, while the block mountains of Otago and less sharply peaked mountains in Canterbury and Marlborough display these features on varying scales. Some forms are considered to be fossil, while others are at present active. This paper reviews the distribution and character of periglacial phenomena in New Zealand, as well as the broad factors controlling their origin and development. L'occurrence des phénomènes et de l'activité périglaciaire en Nouvelle Zélande est réglée par l'altitude, surtout modifiée par al topographie et la lithologie. Ainsi les montagnes de type alpin formant l'épine de l'ǐle du Sud (Alpes du Sud) ne montrent pas beaucoup de sols à figures géometriques, alors qu'on les trouve à plusieurs échelles dans les montagnes d'Otago et celles moins pointues de Canterbury et Marlborough. On pense que quelques unes de ces formes seraient fossiles, mais que d'autres seraient actives actuellement. Cette communication passe en revue la répartition et le caractére des phénomènes périglaciaires en Nouvelle Zélande ainsi que les facteurs généraux qui contrǒlent leurs origines et leur developpement.
