We present results derived from a high-resolution cosmological N-body simulation in which the equations of motion have been changed to account for MOdified Newtonian Dynamics (MOND). It is shown that a low-Omega0 MONDian model with an appropriate choice for the normalisation sigma8 of the primordial density fluctuations can lead to similar clustering properties at redshift z=0 as the commonly accepted (standard) LCDM model. However, such a model shows no significant structures at high redshift with only very few objects present beyond z>3. For the current implementation of MOND density profiles of gravitationally bound objects at z=0 can though still be fitted by the universal NFW profile.
