In order to test if the molecular ``shells'' observed by Charmandaris et al. (\cite{ccv00}) could be due to a molecular outflow, we have mapped CO in J=1->0 and 2->1 along the jet axis of Centaurus A. Where our map coincides with their observed positions, like them, we obtain 4sigma detections with a similar antenna temperature for CO 1->0, although both transitions appear to be somewhat wider in velocity dispersion than theirs. As well as these, we have several tentative detections at distances of ga 5 kpc from the nucleus, and although these results are of too poor quality in order to verify or refute the shell model in favour of a molecular outflow, our observations of the inner kpc do suggest that at least a small-scale outflow is a possibility. Whether this would be a component of a larger-scale outflow or exists in conjunction with the molecular gas shells will have to wait for a much more extensive mapping of the large-scale gas distribution in Centaurus A, for which these and the results of Charmandaris et al. (\cite{ccv00}) will hopefully provide sufficient motivation. Based on results collected at the European Southern Observatory, La Silla, Chile.
