New Zealand is a sliver of the supercontinent Gondwana. The islands are only the visible part of a much larger submerged subcontinent that separated from Australia, on the eastern margin of Gondwana, around 85 million years ago.
Since the Cambrian geological period (over 500 million years ago), sea levels and the land have risen and fallen many times. Periods of mountain building have been followed by epochs when mountains eroded away. Huge volcanoes erupted and massive earthquakes and landslides have ravaged the earth. Great glaciers have lain over much of the land, melted away and then returned as the climate has repeatedly cooled and warmed over time spans hard to comprehend.
