I think this tiny shell is a diloma. That is a mussel shell that it is cruising on.

Was Zediloma atrovirens [Philippi] a common tidal zone shell where rocks are present. Listed AWB Powell, Shells of New Zealand, Plate 8 #11.
Can't be found in WoRMS or NZ Mollusca by either Genus or specific epithet. Mystified as to why it isn't in WoRMS at least as an antiquated name. Appears Suter p. 117 [= morio Suter non Troschel, 1851]
WoRMS lacks D. morio.
NB Close examination shows hole exposing umbilicus is damage. Please ignore this feature.
Some distinguishing features. Blue, freckled, apex turns through two distinct pitches [common in Diloma sp].

In beach drift in gravel and shell fragments at low tide. First one of this species for me...! Very fresh, possibly washed up because of the Tsunami. Found when I was digging the gravel to find some shells. Very rare to see them in Auckland. There are also some records of this species in Rodney, mainly by diving.
I will upload a photo of this specimen later.
