Map of the lost continent of Zealandia

"Zealandia — or Te Riu-a-Māui, as it's referred to in the indigenous Māori language — is a 2 million-square-mile (5 million square kilometers) continent east of Australia, beneath modern-day New Zealand. Scientists discovered the sprawling underwater mass in the 1990s, then gave it formal continent status in 2017... 

Now, GNS Science — a geohazards research and consultancy organization owned by the government of New Zealand — hopes to raise Zealandia (in public awareness, at least) with a suite of new maps and interactive tools that capture the lost continent in unprecedented detail."
