Bulk NdNiO{sub 3} and thin films grown along the pseudocubic (001){sub pc} axis display a 1st order metal to insulator transition (MIT) together with a Néel transition at T = 200 K. Here, we show that for NdNiO{sub 3} films deposited on (111){sub pc} NdGaO{sub 3}, the MIT occurs at T = 335 K and the Néel transition at T = 230 K. By comparing transport and magnetic properties of layers grown on substrates with different symmetries and lattice parameters, we demonstrate a particularly large tuning when the epitaxy is realized on (111){sub pc} surfaces. We attribute this effect to the specific lattice matching conditions imposed along this direction when using orthorhombic substrates.
