Fears some of our roads are just not safe enough, after reports a section of State Highway 1 north of Auckland has been peeling off and sticking to cars.

Police say there were more than 40 complaints from motorists with tar stuck to their vehicles from the highway in Dome Valley on Saturday.

It will be closed overnight for repair work.

Transporting New Zealand Chief Executive Nick Leggett told Tim Dower that there's a couple of different issues at play for drivers.

He says it adds costs for all motorists and also compromises safety, making it important that our roads are smooth and well-maintained.
