 However, while testing the channel to see if it was safe for Kupe's canoe, Te Kawau-a-Toru got caught in the tidal rip, broke a wing and drowned.The broken reef adjacent to the channel is Kupe's loyal bird turned to stone – Te Aumiti a te Kawau-a-Toru (the currents that swallowed Toru's shag).A nearby rocky point where a lighthouse now stands is the bird's petrified bones.
