No other people were injured.
One of the park's neighbours, who owned the fence that was ploughed through, said she had just pulled up the driveway when she heard the commotion.
Her attention was drawn to the damaged car, which she thought was being used as a training exercise for emergency services.
However, after seeing people running to the scene she quickly grabbed some towels and pillows and rushed to help.
"There were quite a few people running over and quite a few Hurricanes players."
It was only after the incident was over that she realised the car had ploughed "straight through" two of her fences.
Despite the damage to her property she was light-hearted about the situation and said she just hoped the man was okay.
Last night a Hawke's Bay District Health Board spokeswoman said the man was in a stable condition and a police spokeswoman said inquiries were ongoing.
Mr Campbell said he wished the man all the best for a speedy recovery.
