It's now at level one which means minor volcanic unrest.
It was between moderate and high after temperatures in the crater lake reached 46°C in May, but it has now dropped to 23°.
Climbers and trampers had been warned to stay out of the summit hazard zone.
GNS Science said gas levels were now at a typical level for Mount Ruapehu and volcanic tremors had also declined.
