We use the semiclassical Boltzmann equations to describe the exciton-polariton relaxation in a bulk ZnO microcavity at room temperature. We present kinetic phase diagrams which report the lasing threshold versus the main sample parameters, such as the polariton lifetime or the value of the Rabi splitting. We find that the polariton laser is operating close to the thermodynamic equilibrium in most cases which makes advantageous the use of microcavities showing very large Rabi splittings as it is the case in ZnO structures. We find that room temperature polariton lasing could be observed in the samples presently available.
