Earlier outbursts at Taupo had been even larger. An eruption 330,000 years ago buried 2,500 km of land and formed the vast plateau that dominates the centre of the North Island. Much of this region remains a near desert even now.
But New Zealand’s volcanic influences go back even further. Although part of the ancient Gondwana super continent, New Zealand has been adrift and isolated as a volcanic raft for 60 to 80 million years - so long that most animals never reached its shores.
