We study pseudo-Goldstone dark matter in the ℤ3 complex scalar singlet model. Because the direct detection spin-independent cross section is suppressed, such dark matter is allowed in a large mass range. Unlike in the original model stabilized by a parity and due to the cubic coupling of the singlet, the ℤ3 model can accommodate first-order phase transitions that give rise to a stochastic gravitational wave signal potentially observable in future space-based detectors.
