The level of volcanic unrest at Mt Ruapehu has decreased from heightened to moderate, but it can still erupt at any moment.
GNS Science reported volcanic tremor strength at Mt Ruapehu has declined to weak levels over the past week.
The volcanic alert level will stay at level 2 which indicated the primary hazards are those expected during volcanic unrest: steam discharge, volcanic gas, earthquakes, landslides, and hydrothermal activity.
While level 2 was mostly associated with volcanic unrest hazards, Mt Ruapehu is an active volcano and has the potential to erupt with little or no warning.
The aviation colour code remains yellow.
