Police in Hawke's Bay on Thursday had a busy day responding to three separate vehicle smashes in the region, with multiple people seriously injured.
A Police spokeswoman said officers were called to a two-vehicle collision on Taihape Rd at around 3pm.
She said there were initial reports of one person being trapped inside one of the vehicles.

A St John Ambulance spokeswoman said it had three ambulances and a rapid response vehicle at the scene treating three patients - all in a serious condition - who were taken to Hawke's Bay Hospital where they continued to receive treatment.
