No further eruptive activity has occurred at White Island since the moderate eruption last month.
Seismic activity and gas flux from the volcano have been at a low level since the eruption on October 11.
The Aviation Colour Code has been lowered to Green from Yellow.
The potential impact of volcanic activity on aircraft has decreased and GNS Scientists have lowered the Aviation Colour Code to Green from Yellow. The Aviation Colour Codes are based on four colours and are intended for quick reference only in the international civil aviation community.
GNS volcanologist Nico Fournier said despite the seismic activity and gas flux from the volcano being at a low level, White Island remained in a state of volcanic unrest with instability in the volcano-hydrothermal system.
