Abstract We report the measurements of branching fraction (B) and direct \CP-violating asymmetry (\ACP) in the charmless decays \BzK0π0 at Belle~II. A sample of \ep\en collisions, corresponding to 189.8\invfb of integrated luminosity, collected near the Υ(4S) resonance is used for the study. We find 135 signal candidates, and measure \ACP=0.410.32+0.30\stat±0.07\syst and B(\Bz\Kz\piz)=[10.8±1.2\stat±1.0\syst]×106.
