We investigate the tensor correlation in neutron halo nuclei 6He and 11Li. We use the extended (4He/9Li)+n+n models for two nuclei and a special attention is paid for core nuclei (4He and 9Li) to incorporate the tensor correlation in the shell model type wave function. We discuss the Pauli-blocking between core nuclei and last two neutrons and its effect on the spin-orbit splitting of halo nuclei. For 6He, 0{sub 2}{sup +} state is affected by this blocking from the 0s1/2 {yields} 0p1/2 excitation in 4He. For 11Li, the blocking makes the (1s)2 and (0p)2 configurations close to each other in energy and hence mix equal amount of two configurations to develop the halo structure.
