The level of volcanic tremor had started to decrease, but hybrid volcanic earthquakes had appeared.
Hybrid earthquakes were typically associated with the movement of molten material (magma) within an active volcano.
The current episode of activity started in August 2012 with explosions and ash emission and was followed in November 2012 by the extrusion of a small lava dome.
Volcanic unrest has been increasing at White Island since about January 14.
This unrest has been described as some of the most vigorous activity seen at White Island for many years.
GNS Science continues to closely monitor White Island through the GeoNet project.
Weather permitting a 'gas flight' will be made tomorrow morning to ascertain if there have been any changes in the gas flux from the volcano.
