Earthquakes are continuing to rattle Mount Tongariro.
The mountains alert level was bumped from zero to one nearly two weeks ago, after a series of small earthquakes under the volcano.
GNS Volcanologist Dr Brad Scott said they have seen a drop in the number of shakes under the volcano.
He said it started off having around 20 shakes a day, but it is now dropped to between three to 10 a day.
