We present preliminary results of our ongoing programme to obtain subarcsec resolution near-infrared (NIR) images and colour maps of the central regions of a sample of barred galaxies with circumnuclear starbursts, using the CFHT. In those cases where structure is seen in the broad band images, the NIR colour index maps confirm the location of dust lanes and regions of star formation. In those galaxies where the NIR broad band images appear featureless, the colour maps do show evidence for tightly wound spiral or ring structure, as hinted at in the optical.
