Ocean Beach Kiwi SLS Club lifeguarding director Matt Mannington said two young volunteer surf life savers administered first-aid and oxygen aid to the motorcyclist until emergency services arrived.
Mannington said the volunteers were conducting a beach education course when bystanders alerted them to the crash.
"The driver broke his collarbone and suffered other injuries."
Mannington said two access points to the beach were recently closed, and since then it has put pressure on the remaining access points.
"We've seen a lot more traffic up and down the beach as a result, which is a bit more of a worry.
"And we think it could become more of a problem in the future."
There is a 20km/h speed limit on Ocean Beach. Hastings District Council said driving rules are the same as on a road, except for the speed limit.
A HDC spokeswoman said there were signs with the driving rules present at the beach.
Mannington said Ocean Beach had got busier year-on-year, helped recently by the lack of international travel, and he urged beachgoers to adhere to the rules.
"We just ask the public to use common sense and respect beachgoers.
"We will sometimes make comment to drivers, but we can't tell our young volunteers to confront someone who's abusing the beach. We're not there to enforce the road rules."
