A volcano that has been dormant for more than a century has erupted on New Zealand's North Island, leading to ash clouds, road closures and flight cancellations.
Mount Tongariro, one of three volcanoes in the centre of the North Island, erupted just before midnight local time, with reports of loud explosions, spewing rocks and steam.
Rocks and ash were hurled more than a kilometre in the air, but there are no reports of casualties or damage.
Air New Zealand flights to Gisborne, Rotorua, Taupo and Napier and Palmerston North, were delayed or cancelled following the eruption, affecting flights to and from Auckland, Wellington and Christchurch.
The airline said services are resuming, however flights to and from Napier are still affected. The main state highway has since reopened.
