  In this paper, we study the long-time dynamics of 3D non-autonomous
Navier-Stokes-Voigt(NSV) equations with delay. Inspired by [36], we use the
contractive function method to prove the pullback D-asymptotical compactness
and existence of the pullback attractors. Furthermore, we verify the regularity
of pullback attractors by the method in [14, 43, 47] and there exists a unique
family of Borel invariant probability measures which is supported by the
pullback attractors.
