GNS Science said the volcano has historically high levels of sulphur dioxide - the second highest since regular measurements began in 2003.
Duty volcanologist Agnes Mazot said there have been clusters of earthquakes nearby recently, but the relationship between them and the high gas readings was unclear.
She said the change in gas readings was significant, and there was potential for an eruption.
White Island is about 50km from the mainland near Whakatane.
