A motorcycle and car have collided on Amohau St, outside Valentines, in Rotorua.
A police northern communications spokeswoman said police were alerted of the crash at about 4.15pm.
A witness, who didn't want to be named, said he heard the sound of the motorcycle accelerating from the lights at the corner of Amohau and Tutanekai Sts and looked up to see the driver "get the speed wobbles" and fall off.
His bike crashed into the rear of a car about 50m from where he fell off.
The witness said a police car was just a few cars ahead at the lights. He said the rider was able to get up and walk to his bike.
