We present near-infrared narrow- and broad-band imaging of the field of GRB021004, performed with ISAAC on the UT1 of the ESO Very Large Telescope. The narrow-band filters were chosen to match prominent emission lines at the redshift of the absorption-line systems found against the early-time afterglow of GRB021004: [OIII] at z=1.38 and Hα at z=1.60, respectively. For the z=1.38 system we find an emission-line source at an impact parameter of 16'', which is somewhat larger than the typical impact parameters of a sample of MgII absorbers at redshifts around unity. Assuming that this tentative redshift-identification is correct, the star formation rate of the galaxy is 13±2M_☉/yr. Our study reaches star-formation rate limits (5σ) of 5.7M_☉/yr at z=1.38, and 7.7M_☉/yr at z=1.60. These limits correspond to a depth of roughly 0.13L^*. Any galaxy counterpart of the absorbers nearer to the line of sight either has to be fainter than this limit or not be an emission-line source.
