Nuclear magnetic resonance (NMR) studies using $^{11}$ B and $^{69,71}$ Ga have been performed on the tetragonal Ce-based ferromagnet CeRuGaB. The Knight shifts for the nuclei show an Ising-type anisotropy along the axis, similar to results from the static susceptibility. From the Knight shift measurements, the hyperfine coupling constants have been determined. The anisotropy of the spin- lattice relaxation rates indicates that the anisotropy of spin fluctuations are also Ising-like along the axis. The localized character of the electrons in this system is discussed.
