Labour's calling the Government road cone complaints hotline a complete waste of public money.

It's wrapping up six months early - after site visits showed 86 percent complied with the rules on cone quantities. 

Labour Transport Spokesperson Tangi Utikere says the pilot cost $150,000 by September, after beginning in June.

He says there were and more effective solutions to the issue.

"They should have picked up the phone, had a conversation with councils, worked with them to get the information that they needed - it certainly wouldn't have cost them more than $150,000."
