  We present an on-shell renormalization scheme for the neutralino and chargino
mass matrices for two R-parity violating models, namely bilinear R-parity
violation and the munuSSM with one right-handed neutrino superfield. We discuss
in both models how to obtain neutrino masses and mixing angles correctly as
well as differences to the existing DRbar calculations. Both models predict
correlations between neutrino mixing angles and ratios of R-parity violating
decays such as neutralino_1 -> l W which can be tested for example at the LHC.
We point out that there are cases where one has to include the complete NLO
corrections for the decays neutralino_1 -> l W to predict reliably the
correlations between neutrino- and collider-physics. Moreover, we discuss
briefly the implementation of these decays in the public program CNNDecays.
