Vector supports moves by Auckland's mayor to reduce road cones and temporary traffic management.

Wayne Brown says he wants savings from the $145 million Auckland Transport spends on traffic management, which he says is too disruptive.

Vector Chief Executive Simon Mackenzie says it costs them $30 million a year, which is passed on to consumers.

He says current regulations around traffic management aren't flexible enough.

"It's not kind of a risk-based assessment based on the circumstances at that time of day or traffic volume or what else is going on in the surrounding area."
