I report detections of four new HI 21-cm absorbers associated with sources at intermediate redshifts, 0.7 1. Three detections show strong blueshifted features, indicating cold gas outflows. These three sources also tentatively show excess [O II] line luminosity compared to a bulk of the remaining sample, possibly suggesting that the hosts of these AGNs harbour different environments, either due to interaction with the radio jets or due to excess star formation in the host galaxy. Further, a cold HI mass outflow rate of \approx 78 M_{sun} yr^{-1} , assuming T_s = 1000 K, is estimated for the detection towards SDSS J014652.79-015721.2, at z = 0.95904, which is the highest till date in comparison to similar estimates available in the literature.
