A car has crashed into Tikitapu (Blue Lake), near Rotorua.
A police media spokeswoman said they were called at 2.40pm.
"Police have just arrived, there are two people out of the vehicle but we don't know yet if there are any injuries."
She said a tow truck was required to remove the car.

She said at least three fire crews and police attended.
Staff at the Blue Lake Top 10 Holiday Park said they did not see or hear the incident.
