Temporary traffic management contractors are on notice as Mayor Wayne Brown seeks to address the proliferation of road signs and cones in Auckland.

Mayor Brown has commissioned a report to the Government, highlighting the need for changes to the rules governing road signs.

The Mayor has expressed frustration, stating that the current situation is "not only a waste of money, it's annoying to people".

It's estimated that there are approximately 1 million road cones in use across New Zealand, sparking calls for reform.
