Police say motorists should expect the road to be closed while responders attend the crash.
Fire and Emergency northern communications shift manager Paul Radden said two fire crews from Matamata were helping police at the scene.
A photographer at the scene earlier this afternoon said traffic from Tauranga was banked up to the Ruahihi power station and vehicles were being turned around.
