Abstract: We present a search for the rare decays B -> h* nu nubar, where h* standsfor a light meson. A data sample of 535 million BBbar pairs collected with theBelle detector at the KEKB e+e- collider is used. Signal candidates arerequired to have an accompanying B meson fully reconstructed in a hadronic modeand signal-side particles consistent with a single h* meson. No significantsignal is observed and we set upper limits on the branching fractions at 90%confidence level. The limits on B0 -> K*0 nu nubar and B+ -> K+ nu nubar decaysare more stringent than the previous constraints, while the first searches forB0 -> K0 nu nubar, pi0 nu nubar, rho0 nu nubar, phi nu nubar and B+ -> K*+ nunubar, rho+ nu nubar are reported.
