  The large level limit of the N=2 minimal models that appear in the duality
with the N=2 supersymmetric higher spin theory on AdS_3 is shown to be a
natural subsector of a certain symmetric orbifold theory. We study the relevant
decompositions in both the untwisted and the twisted sector, and analyse the
structure of the higher spin representations in the twisted sector in some
detail. These results should help to identify the string background of which
the higher spin theory is expected to describe the leading Regge trajectory in
the tensionless limit.
