Geography

During the Last Glacial Period when sea levels were over 100 metres lower than present day levels, the North and South islands were connected by a vast coastal plain which formed at the South Taranaki Bight. During this period, most of the North Island was covered in thorn scrubland and forest, while the modern-day Northland Peninsula was a subtropical rainforest. Sea levels began to rise 7,000 years ago, eventually separating the islands and linking the Cook Strait to the Tasman Sea.
