At the same time, the aviation warning was raised from yellow to orange because of the potential risk to aircraft in the area.
According to the GeoNet update of October 21, 2026, new observations indicate a weak and continuous eruption, during which small amounts of volcanic ash are being emitted. This is after an update of October 19 reported intermittent emissions of steam, gases, and ash.
Despite the limited activity at this time, authorities warn that a more powerful eruption could occur without warning. The main risk is centered in the crater area and the waters surrounding the island, especially to the southeast.
Volcanic ash may pose a risk to aircraft, including the potential for damage to aircraft engines and systems. However, raising the alert level does not in itself indicate widespread disruption to aviation. As of this update, there have been no reports of closures of major airports in New Zealand or widespread cancellations of commercial flights.
The volcano is located in the Bay of Plenty, about 48 kilometers off the coast of New Zealand's North Island, and is also known for the disaster in December 2019, in which 22 people were killed in an eruption that occurred during a tourist visit to the island.
