The speed limit around Auckland's Waterview Tunnel is going up to 100km/h again.
The NZ Transport Agency announced late this afternoon that the variable speed limits will be extended on sections of State Highway 16 and 20 around the tunnel.
Since opening in July, the limit has dropped to 80km/h in the area. Authorities have said the drop in the speed limit is in keeping with international best practice.
However, it has proven to be unpopular with many motorists.
NZTA's transport agency system design manager Brett Gliddon said: "We want to ensure that people's journeys on the motorway are as safe and easy as we can make them.
