In this paper, the lepton flavor violating {tau}{yields}lP(V) (P, V={pi}{sup 0}, {eta}, {eta}{sup '}, {rho}{sup 0}, {omega}, {phi}) and {tau}{yields}3l (l=e, {mu}) decays are studied in the framework of the type-III seesaw model, in which new triplet fermions with a zero hypercharge (Y=0) interact with ordinary lepton doublets via Yukawa couplings, and affect tree-level leptonic Z-boson couplings. We investigate the experimental bound from the leptonic Z decay to get constraints on the existing parameters space. We predict that the upper limits on the branching ratios of {tau}{yields}lP(V) and {tau}{yields}3l can reach the experimental current limits.
