A number of people are taking to social media tonight to report what they believe sounded like explosion noises around the Bay of Plenty.
Two people have messaged SunLive's Facebook to say they heard what sounded like huge booms.
"We and many others heard across the BOP. It shook our door and others houses too. What's happening?" says one reader in Ohauiti.
"There was a big one about 20 minutes ago."
People from Mamaku, near Rotorua, are also reporting the noise.
A number of different posts have appeared on the Mamaku Notice Board Facebook page describing a loud muffled bang "that made the house shake".
Some people say it may have been an earthquake, but nothing has been reported by GeoNet so far.
SunLive will provide an update when more information comes to light.
