Whakamaru - No idea why the site you link has that listed as a supervolcano , it's an area of high seismic activity, but it's no supervolcano.
Whakamaru is where we have a few of the main hydroelectric and geothermal power stations which supply a large chunk of our national grid.
Whakamaru isn't even listed as being active, or potentially active .
New Zealand’s active or potentially active volcanoes:
Those volcanoes that have erupted within the last 10,000 years, especially those with multiple eruptions in that period, are the most likely to erupt
again. Together with Taranaki (Mt Egmont) and the Tūhua caldera (Mayor Island), most of the active volcanic centres are in the Taupō Volcanic Zone,
and include Ruapehu, Ngāuruhoe, Tongariro, Taupō caldera, Okataina caldera, Mt Edgecumbe (Pūtauaki) and Whakaari (White Island).
Taranaki (Mt Egmont) has erupted at least a dozen times since about 1300 AD, the most recent (Tahurangi) occurring probably around 1755. Taranaki has
generated a series of lahars in the last few thousand years, as well as eruptions, and part of the volcano's summit probably collapsed between 1860
Mayor Island (Tūhua), 25 kilometres offshore in the western Bay of Plenty, has erupted several times in the last 10,000 years. A caldera-forming
event about 7,000 years ago spread tephra over part of the North Island. The latest eruption, of lavas, took place possibly about 3,000 years ago.
Mt Edgecumbe (Pūtauaki), an andesitic cone volcano, was active about 3,200 years ago.
Small eruptions have occurred irregularly over a large area in the Auckland volcanic field, the latest being the formation of Rangitoto Island around
1400 AD. Past experience suggests that future eruptions in Auckland are likely to come from new vents rather than existing cones.
If you can provide evidence that worldwide we are seeing more frequent volcanic activity than in previous years then please provide the information to
us here so we can see for ourselves.
Every volcano has geological events - I think you need to do a bit of research into how active we are here. We have a ridiculous amount of volcanoes
and we have multiple fault lines running straight up the country.

Only one of those was felt or even mentioned on our news here, and we don't get alot of news. If an earthquake is felt, it's all over everything
from TV to newspapers.
If you go to magma.geonet.org.nz...
you can search for a complete listing of seismic activity in New Zealand as far back as
I can't link the information here because the way it works is it puts all the info into a text file for you to download, these can get quite
We have an average of 2-3 earthquakes per day here, very rarely are any of these felt, not including the recent events in Christchurch.
If we have even the slightest chance of heightened geothermal activity or volcanic-related sesmic activity it's plastered all over the news
