  We present near-infrared broad-band polarization images of the nuclear
regions of the Circinus galaxy in the J, H and K bands. For the first time the
south-eastern reflection cone is detected in polarized light, which is obscured
at optical wavelengths behind the galactic disk. This biconical structure is
clearly observed in J and H band polarized flux whilst in the K band a more
compact structure is detected. Total flux J-K and H-K colour maps reveal a
complex colour gradient toward the south-east direction (where the Circinus
galactic disk is nearer to us). We find enhanced extinction in an arc shaped
structure, at about 200pc from the nucleus, probably part of the star-formation
ring.
  We model the polarized flux images with the scattering and torus model of
Young etal, with the same basic input parameters as used by Alexander etal in
the spectropolarimetry modelling of Circinus. The best fit to the polarized
flux is achieved with a torus radius of ~16pc, and a visual extinction Av,
through the torus, to the near-infrared emission regions of >66 mags.
