A police car has been hit by a flash flood and washed off the road into a swollen creek, stranding an officer on top of the vehicle.

The car was washed away on Clevedon-Kawakawa Rd, as heavy rain continues to drench areas near Auckland.

Counties Manukau South Area Commander Inspector Mark Rowbottom said two police officers were returning from Kawakawa Bay about 1.30am when their vehicle was hit by flood waters.

"Their car rapidly filled with water and the officers had to abandon the vehicle," he said.

"They exited the car and sought higher ground where they waited until they were rescued by the Clevedon Fire Service.

"A big thanks to the Fire Service for their assistance."


Resident Russell Heenan said the police car was almost completely submerged when he passed by.

Heenan spotted the vehicle after an officer in another police car flashed his lights as a warning.

He said the flood water was about 1.5m above fence height.

The police officer managed to scramble out of the car but had to stand on the car for about half an hour before the water had subsided, Heenan said he was told.

Heenan said he's never seen such flooding in the area before, and a neighbour compared it to severe flooding 50 years ago.

Keith Pye, who works at the Kawakawa Bay garage, said flooding near the town was "bad" and between 10 and 12 homes have been evacuated.

He said power to the seaside town east of Auckland had been intermittant, and only four-wheel-drives were able to access Kawakawa Bay.

Pye said his garage had been partially flooded, and children have been unable to go to school in Clevedon or Howick.

He said the road to Orere Point was completely cut off.

Kawakawa Bay Store and Takeaways manager Yougesh Patel said flooding in the town's streets wasn't too bad, but people were unable to get in or out.

He said the road west to Clevedon was partially flooded, and the polo grounds near Clevedon were completely flooded.
