Mahuika crater is a submarine bolide impact crater, 20 ± 2 km wide and over 153 m deep, on the New Zealand continental shelf named after the Māori god of fire. It was discovered by Dallas Abbott and her colleagues from the Lamont-Doherty Earth Observatory of the Columbia University.
Based on elemental anomalies, fossils, and minerals, which are interpreted to be derived from the impact, found in an ice core from the Siple Dome in Antarctica, it is believed that the impact which created the Mahuika crater occurred around 1443 AD.
