Conservation
According to records in the Te Papa database, Haupatoto Bush has been sampled for land snails only a few times in the 1980s, 1990s, and early 2000s. More than 370 samples from the surrounding area of NZ 260 map sheet N02 (Fig. 2) have been checked for occurrences of S. haupatoto for this assessment. This species is probably restricted to the Haupatoto-Whareana area, SW of North Cape. The 2010 NZTCS assessment ranked this species as ‘At Risk: Relict’, with the qualifier ‘Range Restricted’ (RR). A change to ‘At Risk: Naturally Uncommon’ is suggested here, with the qualifiers ‘Data Poor: Size and Trend’ and ‘Biologically Sparse’.
