  "abstract": "We map the kinematics of the inner (200 pc) narrow-line region (NLR) of the Seyfert 2 galaxy NGC 1068 using the instrument NIFS and adaptative optics at the Gemini North Telescope. Channel maps and position-velocity diagrams are presented at a spatial resolution of $\\sim$ 10 pc and spectral resolution $\\sim$ 5300 in the emission lines [Fe II] {\\lambda} 1.644 {\\mu}m, H$_2$ {\\lambda} 2.122 {\\mu}m and Br{\\gamma}. The [Fe II] emission line provides a better coverage of the NLR outflow than the previously used [O III] {\\lambda} 5007 emission line, extending beyond the area of the bi-polar cone observed in Br{\\gamma} and [O III]. This is mainly due to the contribution of the redshifted channels to the NE of the nucleus, supporting its origin in a partial ionized zone with additional contribution from shocks of the outflowing gas with the galactic disc. We modeled the kinematics and geometry of the [Fe II] emitting gas finding good agreement with the data for outflow models with conical and lemniscate (or hourglass) geometry. We calculate a mass outflow rate $1.9^{+1.9}_{-0.7}$ M$_{\\odot}~$yr$^{-1}$ but a power for the outflow of only 0.08% L$_{Bol}$. The molecular (H$_2$) gas kinematics is completely distinct from that of [Fe II] and Br{\\gamma}, showing radial expansion in an off-centered $\\sim$ 100 pc radius ring in the galaxy plane. The expansion velocity decelerates from $\\sim$ 200 km/s in the inner border of the ring to approximately zero at the outer border where our previous studies found a 10 Myr stellar population.",
