Mt Tongariro alert downgraded
Scientists have lowered the alert level on Mt Tongariro, nearly two weeks after the volcano erupted.
Though some ash was emitted in the first few days following the eruption on August 6, there has been no significant activity since.
Vulcanologist Steven Sherburn said the alert level had been changed from two to one because the volcano was no longer erupting.
Level one indicates there are "signs of unrest'' and a "departure from typical background surface activity''.
Sherburn said: "volcanic gas flux measurements after the eruption were high, but poor weather has prevented any recent measurements.''
He said any further eruption could occur with little or no warning, but it was unlikely.
"Over the next seven days the scenario considered most likely is that there will be no further eruptions.
"The next most likely scenario is that any eruptions will be of similar size to the eruption on August 6,'' Sherburn said.
"The scenario considered least likely is that larger eruptions will occur.''
Scientists will continue to monitor the volcano, he said.
The aviation colour code remained at yellow.
