A new eruption of steam and mud at Wai-O-Tapu Thermal Wonderland south of Rotorua has caught a man by surprise but a specialist says while it is uncommon it's not unexpected.
Thomas Rodda drives a shuttle from Rotorua to local sites and was taking passengers to Wai-O-Tapu on Saturday when he saw the mud spurting into the air.
"I go past that pool pretty much every day and I've never seen it do that."
There is a large mud pool at Wai-O-Tapu but Rodda said the hot mud and water seemed to be erupting from next to it.
