Notes
- The scientific name means "smooth back".
- Notes about 2008-10 cycle of NZ threat classification for Reptiles (Hitchmough et al 2010): Greatly improved knowledge, Aotea population appears stable, status of Hauturu population still unknown but predicted to be increasing.
- Notes about 2012-14 cycle of NZ threat classification for Reptiles: (Hitchmough, et al.
- 2012): Distribution patchy on Aotea - 4 catchments have reasonable populations.
- Repeat survey done on Aotea in 2012, 74 individuals found, including 1 recapture from 2010 (none from 2008).
- Similar numbers relative to effort from 2008 and 2010, so inference is that populations are stable in these areas.
- 1 more found on Hauturu (not confirmed); likely to be slowly increasing.
