To understand about the continent to which countries like New Zealand belong to, we need to know more about the continents and its history. We all have been learning from schooldays that our planet consists of seven continents, i.e., Asia, Africa, North America, South America, Europe, Australia, Antarctica and five oceans Pacific, Indian, Atlantic, Southern and Arctic ocean on our planet Earth. The best way to know where New Zealand lie is to study each continent one by one. Let's start with the largest continent, Asia.

However, we cannot be so sure of this because with time theories regarding this are evolving. Some theories suggest that New Zealand is a part of Oceanic Country and some theories say that it is a neighbor of the continent Australia.So, to get the exact answer, we will have to keep digging the history of the continents and keep learning about the geography of our planet Earth.
