The Westpac Helicopter crew from Auckland were called about 1.10pm and flew the man to Whangarei Hospital. He had some bruising to his face and was released.
The incident has drawn a strong warning from Northland's top traffic officer.
Inspector Murray Hodson said the incident could have been disastrous and more care was needed when driving on 90 Mile beach which was considered a road.
"He may well have been trying to impress the females but it's lucky he didn't end up in a much more serious condition," Mr Hodson said.
"The terrain on 90 Mile Beach is very unpredictable. Even though it's straight it's hard to see the changes in the contours."
He also said it was the driver's responsibility to ensure passengers were abiding by the law.
