The first Kanohi Nuva were the Kanohi formed when the Toa Mata transformed into the Toa Nuva and the thirty subsequent Kanohi Nuva made by the residents of Artakha that were teleported to Mata Nui for the Toa Nuva. After the Bohrok-Kal's theft of the Nuva Symbols, the Turaga Metru advised the Toa Nuva to seek out the thirty hidden Kanohi Nuva. With the Turaga's instruction, each Toa Nuva successfully obtained these Kanohi Nuva, which remain at their Suva as secondary masks with the exception of Tahu Nuva's, which were destroyed along with Ta-Koro by the Rahkshi.
The Kanohi Rua Nuva was formed when Lewa Nuva, Gali Nuva, and Kopaka Nuva merged into Toa Nuva Kaita Wairuha Nuva to battle the three Bohrok-Kal Gahlok-Kal, Lehvak-Kal, and Kohrak-Kal. When Wairuha Nuva was forced apart into the three Toa Nuva who had formed him, the mask ceased to exist. The Kanohi Aki Nuva would likewise form if Tahu Nuva, Pohatu Nuva, and Onua Nuva were to merge into Akamai Nuva, although such a fusion has never occurred.
Artakha later gave each of the Toa Nuva an environmentally shape-shifting Kanohi Nuva along with the rest of their new Adaptive Armor, replacing the Kanohi Nuva they had worn as their primary masks. Together with the thirty Kanohi Nuva previously obtained, these are the only Kanohi Nuva in existence aside from the Zaethos Nuva.
As Kanohi Nuva are more powerful than standard Kanohi, they have have certain differences that set them apart:
- They grant their user the ability to share their mask power with nearby beings, even Matoran and Rahi, although the range for this is limited.
- Only a Toa Nuva can directly use Kanohi Nuva.
