Zealandia

In our own world, New Zealand is an often overlooked nation within the anglosphere. Overshadowed by mainly Australia, New Zealand’s sibling in the region. Although around 100 million years ago, New Zealand was much bigger, a continent like Australia, though smaller, it rivalled the land down under in size and potentially in its unique wildlife. Zealandia was it's name, a majestic mess of peninsulas, plateaus, tundra and monsoonal rainforests. Though before it got its chance on the world stage, it sunk into the ocean about 80 million years ago. Flushing away the dreams of a rival landmass to Australia.

Though what if Zealandia never sunk into the ocean, and stuck around into our modern civilisation? What if Zealandia still existed?
