A parking sign in an Auckland carpark says SUVs, vans, utes and commercial vehicles are prohibited from parking there.

The "tractors" of upmarket Auckland suburb Remuera have been banned from a local car park.

The top level car park on Clonbern Rd, near Remuera's local shops and supermarket, recently had signs put up stating there was "no entry for SUVs, vans, utes and commercial vehicles". There was also a vehicle weight restriction of 2000kg.

Auckland Transport (AT) put up the signs and is now considering a height barrier to further stop drivers of vans, utes, commercial vehicles and SUVs - also known as "Remuera tractors".

Ōrākei Ward councillor Desley Simpson said she was concerned about the sign's location and AT putting "no SUVs" as it had not been defined.

"There are a lot of four by fours in Remuera," Simpson said.

Last Wednesday, Simpson posted about the car park on her Facebook page.

Simpson was still seeking clarification on what AT meant by "SUV" but in the comments section of her page, she told commenters to "think 'Remuera tractor'".

"I mean, no one knows how much their car weighs," she said.

"We've got all this trouble with the buses in the ward because a lot of kids go to private schools - we've got St Kentigern's College, Baradene, Kings...all within it.

"People use that kind of vehicle to transport their kids and of course they shop in Remuera, particularly at the supermarket and local retailers."

SIMON MAUDE/STUFF Ōrākei Ward councillor Desley Simpson says there were a lot of four by fours in Remuera.

The car park had no evidence of "structural distress but there has been things like cracks in the top level and beams", Simpson said.

"What they're saying is we just need to try, where possible, not add too much weight to it - so if you had a large car, it'd be better if you parked at the bottom."

The ban has raised concerns for the Remuera Business Association and its business development manager Cecilia Ngo said she was organising an "urgent consultation" with AT.

The association had not been told about what was happening to the car park, Ngo said.

"We're a bit concerned about losing the car park for Remuera - it would really affect all the businesses and retailers," Ngo said.

AT spokesman Mark Hannan said the car park had been assessed several times since it was built in 1982.

Repairs had been undertaken but there was still an issue with water ingress, Hannan said.

"We must make it clear there is no evidence of structural distress and there is no need to close the carpark," Hannan said.

The weight restriction was implemented in 2014 but "as the weight restriction was not being adhered to, we have recently made the signs more visible to reinforce the need for this weight restriction to be complied with", he said.

Larger SUVs can weigh about 2500kg. ​
