Forty million years later India (with Madagascar) broke away and the Atlantic Ocean opened up, separating Africa from South America. Eighty million years ago, the landmass that was to become New Zealand, broke away from Gondwana, splitting away from Australia and Antarctica as the Tasman Sea opened up.
Does New Zealand fall under Australia?
New Zealand is part of a region known as Australasia, together with Australia.
Is New Zealand a country of Australia?
Australia and New Zealand are part of the Oceania continent, and are on separate tectonic plates to Asia. That’s why when people talk about the two countries, they may not think of them as being part of Asia. But they are an integral part of the Asia-Pacific region, also known as Apac.
