  We present the results on the stellar Initial Mass Function (IMF)
normalisation of 68 massive ($M_\ast=10^{11}-10^{12}$$M_\odot$) Early-Type
Galaxies (ETGs) at redshift of $\sim$1. This was achieved by deriving the
stellar Mass-to-Light ratio (M/L) of the galaxies through axis-symmetric
dynamical modelling and comparing it to the same derived via stellar population
modelling through full spectrum fitting. The study also employs an Abundance
Matching technique to account for the dark matter within the galaxies. The
results demonstrate that massive ETGs at high redshifts on average have a
Salpeter-like IMF normalisation, while providing observational evidence
supporting previous predictions of low dark matter fraction in the inner
regions ($\lesssim$ 1R$_{\rm e}$) of galaxies at higher redshift.
