Zieria abscondita was first formally described in 2020 by Paul Irwin Forster from a specimen he collected in Bloodwood Creek Nature Refuge in Crossdale in 2017. The specific epithet (abscondita) means 'hidden' or 'concealed', and "alludes to the occurrence of this species in a rocky gorge and to its late discovery".
This zieria is only known from Crossdale, where it occurs in in a more or less continuous linear strip along a waterway in rocky terrain in low woodland with an overstorey of Eucalyptus dura and Lophostemon confertus.
Zieria abscondita is listed as of "least concern" under the Queensland Nature Conservation Act 1992.
