Abstract We report the measurements of branching fraction (B) and time dependent \CP-violating asymmetry (\ACP and \SCP) in the charmless decays \BzK0π0 at Belle~II. A sample of \ep\en collisions, corresponding to 361.5\invfb of integrated luminosity, recorded near the Υ(4S) resonance is used for the study. We find XXX signal candidates, and measure B(\Bz\Kz\piz)=[XX±YY\stat±ZZ\syst]×106 and \ACP=XX±YY\stat±ZZ\syst.
