A police spokeswoman said officers were currently helping with traffic management and they were putting cordons in place around State Highway 41 and State Highway 1.
There was a diversion along Puataata Rd, she said.
A St John spokeswoman said one ambulance was at the scene on standby.
Taupo District Council senior customer officer Alex Good said a staff member was on scene monitoring the flow of water from the fire hoses going into the stormwater.
"No water is going into the storm water. If there is anything it's just coming straight from the fire trucks themselves"
"The water is under control and shoudn't be contaminating the drinking or stormwater," she said.
