  We present measurements of $\rho^0$, $\omega$ and K$^{*0}$ spectra in
$\pi^{-} + $C production interactions at 158 GeV/c and $\rho^0$ spectra at 350
GeV/c using the NA61/SHINE spectrometer at the CERN SPS. Spectra are presented
as a function of the Feynman's variable $x_\text{F}$ in the range $0 <
x_\text{F} < 1$ and $0 < x_\text{F} < 0.5$ for 158 GeV/c and 350 GeV/c
respectively. Furthermore, we show comparisons with previous measurements and
predictions of several hadronic interaction models. These measurements are
essential for a better understanding of hadronic shower development and for
improving the modeling of cosmic ray air showers.
