Recent laboratory measurements of isotopologue ⁵⁸NiH by laser excitation around 17000-18000 cm^-1 in a magnetic field have allowed us to study several electronic systems of this molecule. Zeeman patterns were analysed using literature values for ground state Landé factors. Effective electronic Landé factors g_ eff have been determined. They show strong variation with parity in the rotational levels in some '=3/2 states, giving evidence for extensive mixing between excited electronic states. \newline
