  A cerium containing pnictide, CeNiAsO, crystallized in the ZrCuSiAs type
structure, has been investigated by measuring transport and magnetic
properties, as well as specific heat. We found that CeNiAsO is an
antiferromagnetic dense Kondo lattice metallic compound with Kondo scale $T_K
\sim$ 15 K and shows an enhanced Sommerfeld coefficient of $\gamma_0 \sim$ 203
mJ/mol$\cdot$K$^{2}$. While no superconductivity can been observed down to 30
mK, Ce ions exhibit two successive antiferromagnetic (AFM) transitions. We
propose that the magnetic moment of Ce ion could align in the G type AFM order
below the first transition at $T_{N1}$=9.3 K, and it might be modified into the
C type AFM order below a lower transition at $T_{N2}$=7.3 K. Our results
indicate that the 3$d-4f$ interlayer Kondo interactions play an important role
in Ni-based Ce-containing pnictide.
