The Northern HIPASS catalogue (NHIC AT) is the northern extension of the HIPAS S catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of +2 300 kms -1. Sources with -300 < hel < 300km s -1 were excluded to avoid contamination by Galactic emission. In total, the entire HIPASS survey has found 5317 galaxies identified purely by their HI content. The full galaxy catalogue is publicly available at http://hipass.aus-vo.org. 2006 RAS.
