We report on the magnetic phase diagram of a hole-doped cuprate Ca2-xNaxCuO2Cl2, which is free from buckling of CuO2 planes, determined by muon spin rotation and relaxation. It is characterized by a quasi-static spin-glass-like phase over a range of sodium concentrations (0.05 <= x <= 0.12), which is held between the long-range antiferromagnetic (AF) phase (x <= 0.02) and the superconducting phase where the system is nonmagnetic for x >= 0.15. The obtained phase diagram qualitatively agrees well with that commonly found for hole-doped high-T-c cuprates, strongly suggesting that the incomplete suppression of the AF order for x > 0.02 is an essential feature of the hole-doped cuprates.
