​Local firm United Civil Construction has been awarded a $1.8M contract to upgrade the busy intersection of Tarewa Road and Porowini Avenue.

It is part of a package of projects in the southern part of the city over the next two years to reduce congestion and delays.

The upgrade will provide extra approach lanes on Porowini Avenue, at the western side of the Porowini/Tarewa intersection and on Tarewa Road, at the northern side of the intersection.

“This will allow the traffic signals at the intersection to operate much more efficiently and will make traffic move much more smoothly during the evening peak,” said Council Roading Manager Jeff Devine. The work will start late in August and should be completed in December.

At around the same time the New Zealand Transport Agency’s $17M State Highway One (SH1)/Tarewa Road intersection upgrade will start.

Also, in the next few weeks, Council contractors will demolish the former paint shop on the corner of Maunu Road and Porowini Ave as a first step in the widening of this intersection. Work on the intersection will start in December and should be completed in May 2019.

Whangarei District Council and New Zealand Transport Agency are coordinating the projects in this relatively compact area to reduce the impacts on commuters.

Instructions for drivers

Porowini Avenue

Each end of the section of Porowini Avenue between Maunu Road and Tarewa Road will become worksites over the next 10 months.

Work at the Tarewa Road/Porowini Avenue intersection will begin at the end of this month and will finish in December.

Road works on the Maunu Road end will begin in December and will finish in May 2019. It will include widening the bridge across the Raumanga Stream.

Traffic management will be in place, but it may be best to take other routes and avoid these areas.

State Highway One/Tarewa

This work will extend from the Information Centre to the intersection with Tarewa Road, along Otaika Road past the bridge and across the Raumanga Stream.

People heading north and south along SH1 will travel through roadworks on this stretch.

People coming into the centre of the city from parts south of Rewa Rewa Road may wish to use Rewa Rewa Road and Kioreroa Road to avoid the roadworks.
