We use a data sample of 2.8{times}10{sup 6} produced {tau}-pair events, obtained with the CLEO II detector, to measure {ital B}{bold (}{tau}{sup {minus}}{r_arrow}{ital h}{sup {minus}}{ital h}{sup +}{ital h}{sup {minus}}({pi}{sup 0}){nu}{sub {tau}}{bold )}, where {ital h} refers to either a charged {pi} or {ital K}. These branching fractions are measured with samples of lepton-tagged and 3 vs 3 events. We find {ital B}({tau}{sup {minus}}{r_arrow}{ital h}{sup {minus}}{ital h}{sup +}{ital h}{sup {minus}}{nu}{sub {tau}})=0.0951{plus_minus}0.0007 m*0.0020 and {ital B}({tau}{sup {minus}}{r_arrow}{ital h}{sup {minus}}{ital h}{sup +}{ital h}{sup {minus}}{pi}{sup 0}{nu}{sub {tau}})=0.0423{plus_minus} .0006{plus_minus}0.0022. We also measure {ital B}({tau}{sup {minus}}{r_arrow}{omega}{ital h}{sup {minus}}{nu}{sub {tau}})=0.0195{plus_minus}0.0007{plus_minus}0.0011 {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
