Question: is new zealand part of the australia continent

Answer: No, New Zealand is not part of the continent of Australia, but of the separate, submerged continent of Zealandia. New Zealand and Australia are both part of the Oceanian sub-region known as Australasia, with New Guinea being in Melanesia. The term Oceania is often used to denote the region encompassing the Australian continent, Zealandia and various islands in the Pacific Ocean that are not included in the seven-continent model.
