We present J-band spectropolarimetry of NGC 1068. We observe polarized broad Pa β and, for the first time, polarized broad Pa γ and HeI. Assuming electron scattering as the polarization mechanism, the polarized broad lines suffer little or no extinction. All the polarized broad lines are redshifted with respect to the narrow lines, attributed to an outflow velocity for the scatterers of 900 ± 200 km s-1.
