We study the gas distribution and kinematics of the inner kpc of sixmoderately luminous (43.43$\leq$log$L_{\rm bol}\leq$44.83) nearby ($0.004 \leqz \leq 0.014$) Seyfert galaxies observed with the Near-infrared Integral FieldSpectrograph (NIFS) in the J(1.25$\mu$m) and K(2.2$\mu$m) bands. We analyse themost intense emission lines detected on these spectral wavebands: [Fe II]1.2570 $\mu$m and Pa$\beta$, which trace the ionised gas in the partially andfully ionised regions, and H$_2$2.1218$\mu$m, that traces the hot ($\sim 2000$K) molecular gas. The dominant kinematic component is rotation in the disc ofthe galaxies, except for the ionised gas in NGC 5899 which shows only weaksignatures of a disc component. We find ionised gas outflow in four galaxies,while signatures of H$_2$ outflows are seen in three galaxies. The ionised gasoutflows display velocities of a few hundred km\,s$^{-1}$, and theirmass-outflow rates are in the range $0.005 - 12.49$M$_{\odot}$yr$^{-1}$ . Theirkinetic powers correspond to $0.005-0.7$ per cent of the AGN bolometricluminosities. Besides rotation and outflows signatures in some cases, the H 2kinematics reveals also inflows in three galaxies. The inflow velocities are$50-80$km\,s$^{-1}$ and the mass inflow rates are in the range $1 - 9 \times10^{-4}$M$_{\odot}$yr$^{-1}$ for hot molecular gas. These inflows might be onlythe hot skin of the total inflowing gas, which is expected to be dominated bycolder gas. The mass inflow rates are lower than the current accretion rates tothe AGN, and the ionised outflows are apparently disturbing the gas in theinner kpc.
