Phenatoma zealandica, common name the New Zealand turrid, is a species of predatory sea snail, a marine gastropod mollusc in the family Borsoniidae.

The acuminate spire has a dark brown apex.

The large body whorl is somewhat inflated and contracted towards the base.

This species is remarkable for the tabulated whorls, the tabulations being very strongly radiately striated, and sometimes furnished with a spiral liration, and the conspicuous sulcations encircling the body whorl.

The slit in the lip is situated just below the broad furrow which grooves the upper part of the whorls.
