Claims of overwhelming public support for a new 110 kilometre per hour speed limit on part of State Highway 1 - north of Auckland

The speed limit on the 5.5 kilometre stretch from Orewa to south of the Johnstones Hill Tunnels is being raised - from today.

NZTA consulted on the proposed speed for the modern motorway last year - with 93 percent of submissions supporting an increase.

Northland Council's Regional Transport Committee Chair Joe Carr says it's a clear win for Northland and Auckland.
