Abstract We present the results of the re-discovery of the decay B0π+ν in 34.6\invfb of Belle II data using hadronic B-tagging via the Full Event Interpretation algorithm. We observe 21 signal events on a background of 155 in a fit to the distribution of the square of the missing mass, Mmiss2, with a significance of 5.69σ, and determine a total branching fraction of (1.58 ± 0.43stat ± 0.07sys) ×104
