Paikea, Kewa, and Ihupuku are names of whales, used mythologically to denote the beings by whom Hema was slain; they are generally called Ponaturi. Paikea was one of the sea monsters, the children of Te Ha-puku, slain by Tāwhaki with hail brought from heaven. Other companions of Paikea were Paraoa (sperm whale), Kekeno (seal), Upokohue (porpoise), Ao.
A paikea, or water-monster, was used by Kahu as a conveyance from Waikato to Manukau, along the seacoast.
