In recent years, Circumnuclear Star Forming Regions (CNSFRs) have been studied in different frequencies and telescopes, diverse studies about connection between nuclear activity and star formation in the CNSFRs were doing using optical data, IFS and models. We obtain data of the Seyfert 2 galaxy NGC 1068 at J band between 1.35-1.32$\mu$ using the 8.1m Gemini telescope and GNIRS IFU mode. We found the radial velocity and intensity maps for [FeII]$\lambda$12570, Pa$\beta$ $\lambda$12814 and FeII $\lambda$13201 lines of all the components. The gas emission has a double origin associated with photoionization by young stars or excitation by collisions, we found a high influence of shocks produced by the jet. The intensity of Pa$\beta$ emission show that this component is ionized by a younger cluster or more massive stars. From the analysis of the velocity fields, the data related with the component one of Pa$\beta$ are consistent with the presence of rotation which is displaced from the maximum continuous, our observations may point to the presence of a bar.
