  Extending the results of \cite{Heem}, \cite{KLRS} on the holographic
representation of local gauge field operators in anti de Sitter space, here we
construct the bulk operators for higher spin gauge fields in the leading order
of $\frac{1}{N}$ expansion. Working in holographic gauge for higher spin gauge
fields, we show that gauge field operators with integer spin $s>1$ can be
represented by an integration over a ball region, which is the interior region
of the spacelike bulk lightcone on the boundary. The construction is shown to
be AdS-covariant up to gauge transformations, and the two-point function
between higher spin gauge fields and boundary higher spin current exhibit
singularities on both bulk and boundary lightcones. We also comment on possible
extension to the level of three-point functions and carry out a causal
construction for higher spin fields in de Sitter spacetime.
