Common names
Hokitika skink

Length: SVL up to 85mm, with the tail being longer than the body length

Weight: unknown


A mysterious species known only from three specimens. Two museum specimens exist, and a live subadult was detected during DOC monitoring of Kapitea skinks (Oligosoma salmo) on the West Coast region of the South Island.

Head has a short, blunt snout, and distinctive denticulate markings on edges of the mouth. Dorsal surface is grey-brown with heavy lighter and darker speckling. Flanks have a dark-brown lateral stripe which begins on the snout and continues along the length of the body and tail. Lateral stripe is notched at upper margin and bordered above by a fawn-coloured dorsolateral stripe, and below by a cream-coloured mid-lateral stripe with regular light spots on upper and lower margins. Flanks below mid-lateral stripe are heavily speckled with cream coloured spots which fade into a cream coloured ventral surface with fine black flecks. Flecks on ventral surface are arranged into streaks which become more prominent on the underside of the tail. 

Hokitika skinks may be confused with other species from the speckled skink complex (e.g. Kapitia skink - Oligosoma salmo), but can be distinguised by the presence of strong denticulate markings on the edges of the mouth, speckles on the belly arranged into streaks, and an additional scale separating the prefrontal scales on the snout.

Life expectancy



Known only from discrete locations near Hokitika, in the West Coast region of the South Island.

Ecology and habitat

Virtually nothing is known about the ecology of Hokitika skinks. They are likely to be diurnal and heliothermic in common with other members of the speckled skink group.

Nothing is known of their habitat preferences. Has been found in habitat which includes rank grass, pasture and river terrace.

Social structure


Breeding biology



Unknown, but likely to be omnivorous in common with other members of the speckled skink species complex.



Conservation strategy

The Hokitika skink is currently classified by DOC as 'Threatened - Nationally Critical'.

Interesting notes

Hokitika skinks are members of the speckled skink cryptic species complex - a group of related taxa with similar morphology that were previously regarded as one highly variable species (Oligosoma infrapunctatum).
