New data suggests that New Zealand may be part of it's own continent, dubbed "Zealandia." For over a decade some scientists have been studying this possibility, finding that Zealandia has many of the characteristics of a continent. For instance, continental minerals such as granite form much of Zealandia's crust. Although much of this landmass is submerged under the Pacific Ocean, it is not seafloor because ocean crust is made of volcanic basalt. Scientists think that at one time this continent was on the surface. If Zealandia were coined to be a continent, it would be the smallest one by far. Zealandia is the Earth's pluto.
