Kaukau

The Kanohi Kaukau was the Mask of Water Breathing. It allowed the user to breath underwater up to a certain depth. The Kaukau Nuva allowed the user to extend the depth at which this mask would work, and allowed the user to share this power with others.

Tahu, Onua, Pohatu, Kopaka, and Lewa all found Great Kaukau masks, but lost them when they became Toa Nuva.
