Ash fall has been reported from an eruption on northern Mount Tongariro at 11.50pm on Monday 6 August.
Central North Island regions may be affected including: Waikato, Hawke's Bay, Gisborne, Manawatu-Whanganui, Bay of Plenty, and Taranaki.
People living in these areas should:
Stay indoors: volcanic ash is a health hazard, especially if you suffer from breathing difficulty. If outside, seek shelter (e.g. in a car or building).
When indoors, close all windows and doors to limit the entry of volcanic ash.
If caught in volcanic ash falls: Wear a dust mask or use a handkerchief or cloth over your nose and mouth; protect your eyes by wearing goggles. Wear eyeglasses, NOT contact lenses as fine ash will get under the lens.
Listen to the radio for updated emergency information and instructions.
