National Advisory – Volcanic Activity
Potential threat
________________________________________
No.: 01
________________________________________
Summary: Minor volcanic activity is occurring at Tongariro - Te Maari craters and could be hazardous in the immediate vicinity of
the craters. Light volcanic ash fall can be anticipated downwind of Tongariro and may impact the following
areas/regions:
• Waikato
• Hawkes Bay
• Gisborne
• Bay of Plenty
People living in or near the affected areas should:
1. If experiencing ash fall, stay indoors. Volcanic ash could be a health hazard, especially if you suffer from
breathing difficulty. If outside, seek shelter (e.g. in a car or building)
2. When indoors, close all windows and doors to limit the entry of volcanic ash.
3. 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.
4. Listen to the radio for updated emergency information and instructions.
5. Do not tie up phone lines with non-emergency calls.
6. Stay out of designated restricted zones. Effects of a volcanic eruption can be experienced many miles from a
volcano.
Detailed safety advice will come from the Department of Conservation, local authorities and emergency services in the
area. People should act on it promptly.
This National Advisory will remain in effect until a cancellation message is issued by the Ministry of Civil Defence & Emergency Management.
