Grey sludge cakes Point Chevalier streets

A mysterious grey sludge has been spotted stretching down a number of roads in Point Chevalier.

The suburb's Meola Rd, Jervois Rd, West End Rd, Pt Chevalier Road and Great North Rd have all been caked with the substance.

The culprit appears to be a rogue sucker that "dropped its load" along the many streets, Auckland Transport spokesman Mark Hannan said.

Also @AklTransport @AklCouncil - the same muppet who showed concrete all over Meola Rd appears to have visited Countdown Pt Chev and left his deposit on Huia Rd and Tui St as well...

"The spill appears to be concrete slurry, probably from wash off, concrete saw cutting or concrete drilling," he said.

An AT contractor went to the slurry-splattered roads last night, cleaning up some of the affected intersections so the line marking is visible to motorists and will return this evening, Hannan said.

But the driver of the offending vehicle is proving hard to find.

"We have a CCTV shot of the vehicle we believe caused the problem, but the photo quality is not that good, so we can't clearly identify the vehicle from the registration number," Hannan said.

"Without a clear ID of the possible offender we would struggle to recover any of the clean-up costs incurred.

Hannan said the general policy is, if AT can identify the individual or vehicle involved, it will seek recovery of the clean-up costs.

He said AT would love to hear any details about the offending vehicle.
