  Meta-conformal invariance is a novel class of dynamical symmetries, with
dynamical exponent $z=1$, and distinct from the standard ortho-conformal
invariance. The meta-conformal Ward identities can be directly read off from
the Lie algebra generators, but this procedure implicitly assumes that the
co-variant correlators should depend holomorphically on time- and space
coordinates. Furthermore, this assumption implies un-physical singularities in
the co-variant correlators. A careful reformulation of the global
meta-conformal Ward identities in a dualised space, combined with a regularity
postulate, leads to bounded and regular expressions for the co-variant
two-point functions, both in $d=1$ and $d=2$ spatial dimensions.
