The branching ratios of the τ- → h- ντ, τ- → h- π0ντ and τ- → h- ≥ 2π0ντ decays have been measured using the 1991-1995 data recorded with the OPAL detector at LEP. These branching ratios are measured simultaneously using three selection criteria and are found to be BR(τ- → h- ντ) = (11.98 ± 0.13 ± 0.16)% BR(τ- → h- π0ντ) = (25.89 ± 0.17 ± 0.29)% BR(τ- → h- ≥ 2π0ντ) = (9.91 ± 0.31 ± 0.27)% where the first error is statistical and the second is systematic.
