Classified as a public road, the speed limit used to be 60km/h. It is one of only two beaches in the region where driving is allowed.
Police conducted Operation Beaches at Karioitahi and Muriwai at the beginning of summer.
Counties Manukau South area prevention manager Matt Hoyes said a number of vehicles were impounded at Karioitahi, including a pink-stickered vehicle on Boxing Day for driving in the “no drive zone” of the beach.
A pink sticker indicates a car is unsafe to drive and should be taken off the road.
Police didn’t provide the figures for how many cars were impounded or the number of speeding tickets issued.
Officers also issued a number of infringements to drivers who were driving in a manner liable to cause injury, damage or annoyance.
“Although a number of vehicles were impounded, most drivers had a current warrant of fitness, registration and permit to drive on the beach.”

Although Operation Beaches had concluded, Hoyes said police would continue to regularly patrol Karioitahi, “to make sure it remains a safe and secure environment for everyone this summer”.
Franklin Local Board chairwoman Angela Fulljames, in an earlier interview, said Karioitahi has been mistreated by careless drivers for a long time.
“Every year we receive complaints from beachgoers, often families, about driver behaviour and their determination to treat the beach as their private speedway despite education campaigns and calls for restraint,” Fulljames said.
