Wahaika are short club-like weapons usually made of wood or whalebone and are used for thrusting and striking in close-quarter, hand-to-hand fighting.
[2] Wahaika translates to "mouth of the fish",[3][4] in reference to the notch on one side which is used to catch an opponent's weapon.
On the other side just above the handle the concave tip above a carved humanoid figure is the primary striking edge,[5] particularly used against the opponent's temples, face, and ribs.
In addition to being a fighting weapon, rangatira would hold wahaika during ceremonies and speeches, especially if they wanted people to pay attention to something important.
[8] The resemblance of the wahaika to the Chilean Mapuche people's clava hand club has been cited as "soft evidence" for Pre-Columbian Polynesia-South America contact.
