The Onewa set was released in 2001 as one of the six Turaga sets. The set consists of thirty pieces.
By combining pieces from Onewa with 8540 Vakama, 8541 Matau, 8543 Nokama, 8544 Nuju, and 8545 Whenua, one can build a Turaga Nui, though official instructions were never released. The set could also be combined with 8531 Pohatu to create a Dikapi.
The set was included in K8533 Find the Power Kit, and could be included randomly packaged in K8532 Ultimate Toa Collection Kit. The set was also included alongside a distribution of K8531 Ultimate Toa and Turaga Collection Kit through the Fall 2001 issue of the LEGO Shop At Home catalogue.
A lever is present on Onewa's back, connected to his right arm, so lowering it causes him to lift his Stone Hammer. The arm is automatically lowered due to a rubber band connecting the lever to his neck.
Onewa wears a tan Noble Komau.
