Results for the remaining zones of the Edinburgh-Cape (EC) Blue Object survey are presented. These are incomplete, but lie in that part of the South Galactic Cap between 50deg and 90deg from the Galactic plane and south of about -12.3{deg} of declination. This part of the survey comprises 79 UK Schmidt Telescope fields covering about 2150deg^2^, in which we find 536 blue objects - including hot subdwarfs (~33 per cent), white dwarfs (~30 per cent), binaries (~12 per cent), cataclysmic variables (~1.5 per cent) and some 'star-like' galaxies (~12 per cent). A further 254 stars observed in the survey, mainly low-metallicity F- and G-type stars, are also listed. Low-dispersion spectroscopic classification is given for all the hot objects and UBV photometry for most of them. Either spectroscopy or photometry is listed for the cooler types.
