Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...
