Timeline of New Zealand history

Before humans (before c. 1300 CE)

• 85 mya: Around this time New Zealand splits from the supercontinent Gondwana.
• 5 mya: New Zealand's climate cools as Australia drifts north. Animals that have adapted to warm temperate and subtropical conditions become extinct.
• 26,500 BP: The world's most recent supereruption occurs at the Taupō Volcano. The eruption covers much of the country with volcanic ash and causes the Waikato River to shift course from the Hauraki Plains to its current path to the Tasman Sea, while its caldera becomes modern Lake Taupō.
• 18,000 BP: New Zealand's North and South islands are connected by a land bridge during the Otira Glacial Maximum of the last ice age. Glaciers spread from the Southern Alps carving valleys and making fiords in the South Island. The land bridge is submerged around 9,700 BCE.
• 181 CE: Hatepe eruption of Lake Taupō.
