Oligosoma is a genus of small to medium-sized skinks found only in New Zealand, Norfolk Island and Lord Howe Island. Oligosoma had previously been found to belong to the Eugongylus group of genera in the subfamily Lygosominae; the Australian genus Bassiana appears to be fairly closely related.
The Otago skink is a rare, endangered species of large skink in the family Scincidae, found in the rocky canyons and grassy patches of Central Otago, New Zealand.
The copper skink is a skink of the family Scincidae that is endemic to the North Island of New Zealand.
Oligosoma alani,, also known as the robust skink is the largest endemic skink to New Zealand. The robust skink is in the family Scincidae and found in the protected nature reserves of the Mercury Islands in the North Island of New Zealand. The robust skink has an at risk - recovering conservation status.
McGregor's skink is a species of lizard in the family Scincidae. The species is endemic to New Zealand.
The marbled skink is a species of skink in the family Scincidae. The species is endemic to New Zealand.
The chevron skink is a large species of skink that is endemic to New Zealand. Previously found across Northland and the northern Auckland Region, it is now found only on the Great Barrier and Little Barrier islands in the Hauraki Gulf. A cryptic forest dweller, it can hide underwater. The chevron skink is the longest species of skink in New Zealand, reaching lengths of up to 340 mm (13 in). It is under threat from introduced rats.

Hardy's skink is a species of skink, a lizard in the family Scincidae. The species is endemic to the Poor Knights Islands of New Zealand.
The slight skink is a skink of the family Scincidae, endemic to the far north of the North Island of New Zealand. The precise distribution is unknown; currently it is only known from localities in the Te Paki region of Northland. It closely resembles the copper skink, Oligosoma aeneum, and was considered to be a member of this species until recently when it was described as a new species using morphological, allozyme and DNA methods. O. levidensum is difficult to distinguish morphologically from O. aeneum, which is probably why it had not been recognised until recently. The main distinguishing feature is the slighter overall body form of O. levidensum compared to O. aeneum. The limbs of O. levidensum are reduced compared to O. aeneum and O. hardyi, the other members of the O. aeneum complex.
The ornate skink is a rare species of skink endemic to New Zealand. Once widespread across the North Island, habitat destruction and predation by introduced species has now reduced their range to scattered localities throughout the North Island and offshore islands.
The Barrier skink is a species of medium-sized skink, a lizard in the subfamily Eugongylinae of the family Scincidae. The species is endemic to New Zealand, where it lives in the alpine habitat of the Darran and Takitimu Mountains of Fiordland. It is one of only two species of New Zealand skinks that live exclusively in the alpine zone, the other being the "Sinbad skink", Oligosoma pikitanga, a closely related species of similar appearance which is found in the same part of the South Island. The Barrier skink was first collected in the 1960s but was overlooked until rediscovery by a pair of mountain climbers in 2005; the species was scientifically described in 2009.
The Mokohinau skink, also known commonly as Towns' skink and the Hauraki skink, is a species of lizard in the family Scincidae. The species is endemic to New Zealand.
The Aorangi skink is a species of lizards in the skink family. The species is native to New Zealand.
The Te Kakahu skink is a critically endangered species of skink native to New Zealand. When discovered, the entire species was inhabiting a single patch of clifftop vegetation on Chalky Island in Fiordland National Park.
The Burgan skink is a nationally endangered species of skink native to New Zealand. It was described from a specimen found near the Burgan Stream, in the Rock and Pillar Range, Central Otago.
The cryptic skink is a nationally vulnerable species of skink native to New Zealand.
Oligosoma lineoocellatum, commonly known as the Canterbury spotted skink, is one of a species complex of several related spotted skink species from New Zealand.
The Chesterfield or Kapitia skink is a species of skink found in New Zealand. Only discovered in 1994 and for years not recognised as a distinct species, it is endemic to a narrow 1 km strip of coastal vegetation on the West Coast of New Zealand, 15 km north of Hokitika. There are fewer than 200 individuals remaining in the wild. Oligosoma salmo is the only New Zealand skink with a prehensile tail, suggesting it was once arboreal and inhabited coastal forest, which was subsequently cleared for dairy farming. Following the partial destruction of its remaining habitat in 2018 by a cyclone, a small captive breeding population was established at Auckland Zoo.
