  The decay width $\tau \to K^{*-}(892) \eta \nu_{\tau}$ was calculated in the
Nambu--Jona-Lasinio model. Four channels were taken into account: the contact
channel (the final states are directly producted from lepton current without
any intermediate meson states), the axial-vector channel with two intermediate
physical states $K_{1}(1270)$ and $K_{1}(1400)$, the vector channel with
intermediate $K^{*}(892)$ meson and the pseudoscalar channel with intermediate
$K$ meson. It is shown that the first two channels give the dominant
contribution to the decay width. Of the remaining two channels, the
pseudoscalar channel plays a more prominent role. The final result is in
satisfactory agreement with experimental data. Prediction for the differential
decay width is presented.
