Ka tū mai tētahi o aua wāhine rā, ko te patu parāoa i te ringa, ka hāpainga mai tana patu ki a Puhihuia, ā nō ka tata, ka whiua te patu rā ki te upoko o te kōtiro nei. Karohia ake, tērā te haere rā, tahi anō te whiunga o te arero o te taiaha rā ki te poho o tērā, koropeke ana, noho ana tērā ki raro (TAH 46:20). / One of those women stood up with a whalebone patu in her hand and raised her patu against Puhihuia and when she was close she aimed a blow with it at Puhihuia's head; but Puhihuia parried it and with one thrust of the point of her taiaha to the chest of that one, she doubled up and sat down.
