Frogs & Lizards

New Zealand’s distinctive herpetofauna

The discipline of herpetology in New Zealand includes lizards, frogs, tuatara, sea turtles, sea snakes, and in rare instances involves the capture of stowaway snakes and turtles/tortoises from other parts of the world. New Zealand rivals temperate Australia in terms of lizard biodiversity, and our herpetofauna have many ancient traits that make them unique internationally; e.g. all New Zealand geckos give birth to live young (usually twins) every 1-2 years.

There are currently c.100 species of lizards recognised for New Zealand, one species of tuatara and three species of native frogs. New Zealand also has three species of sea snakes and five species of turtles in our seas; these species frequently turn up on northern beaches.

Threatened species

Archey’s frog, CoromandelArchey’s frog, CoromandelNew Zealand lizards are threatened by habitat modification and destruction, predators, and in some cases poaching. Large-bodied lizards tend to be most threatened as they tend to be longer-lived, have fewer young, and require more specific habitat to avoid predation than smaller-bodied species. All New Zealand herpetofauna are assigned a threat ranking by the Department of Conservation every 3-4 years (most recently in 2015). There are now 37 species of “Threatened” herpetofauna in New Zealand including eight “Nationally Critical” species. There are 52 “At Risk”, seven “Data Deficient”, and 10 “Not Threatened” species. Over 80% of Threatened and At Risk species have at least one record on private land, and some occur exclusively on private land.

Assessment of Environmental Effects (AEE)

Lizards must be considered in scoping reports and in AEEs in order to achieve an “adequate” assessment of environmental effects (as per Section 88, clause 3 of the Resource Management Act 1991).

Wildlife Act 1953

All New Zealand lizards, frogs and tuatara and all vagrant and migrant species of sea snakes and sea turtles are absolutely protected under the Wildlife Act 1953, and consequently:

  • A Wildlife Act Authority from Department of Conservation (DOC) is required to undertake activities within New Zealand herpetofauna habitat that may result in a significant impact on a species or habitat
  • A handling permit from DOC is required for handling and/or disturbance to any New Zealand herpetofauna
