A hospital spokesman confirmed the man was discharged yesterday from Hawke's Bay Hospital.
The crash was caused when the southbound vehicle driven by a Napier woman went out of control on a bend and crossed into the path of an oncoming vehicle, the driver of which was unable to avoid a collision despite taking evasive action.
Police highway patrolman Brian Farquharson said the seven people were very lucky to escape without serious injury.
Mr Farquharson wanted to commend the passing motorists for assisting before emergence services could arrive.
"They did everything I would have asked of them.
They comforted and tended to victims and helped divert traffic."
Mr Farquharson said this was a timely reminder for motorists to slow down when the road is wet.
"Especially after a hot day when the tar has been bleeding a lot of pollutants and other residue can make its way to the surface after a shower."
He said this makes the road slicker and therefore more dangerous.
"Be sure to give yourself that extra safety margin."
Police are now pleading with motorists to take care after at least seven people died nationally in a deadly weekend on the country's roads.
Five lethal crashes on both Saturday and yesterday brought this year's road toll to at least 303, compared with 271 at the same time last year.
The weekend's toll was higher even than the three days at Labour Weekend.
