Waipu's 'kamikaze corner' could become $1m roundabout

Turning a notorious Waipu intersection into a roundabout will be voted on this Thursday by Whangārei District Council's infrastructure committee.

Councillors will decide whether to approve an unbudgeted $100,000 for detailed design work on the roundabout, which is estimated to ultimately cost between $500,000 and $1 million.

The committee will also consider whether to support the project's inclusion in the council's proposed 2027-2037 Long Term Plan.

Waipu's Neil McLeod who served as a Whangārei district councillor for six years from 1998 to 2004, said it was crucial councillors moved fast to include the project in the 2027-2037 Long Term Plan.

The residents' association member said there was a risk the project could become a lower priority when Whangārei District Council, Kaipara District Council and Northland Regional Council functions were merged into a lower Northland unitary authority by 2028, before a later following move to a single council for the region that included Far North District Council.

McLeod acknowledged the funding was unbudgeted but said it was relatively modest in the context of the council's overall budget.

He said the intersection would become even more important if proposed new four-laned highway connections from SH1 into Waipu meant more traffic using the township's road network.

Thursday's vote follows a local residents' campaign, culminating in a Waipu Residents and Ratepayers Association petition signed by about 1300 people in October calling for a roundabout to address what supporters say are growing safety and traffic-flow concerns.

Petition organiser and association member Ross Boyd of Waipu, said he had dubbed the busy four-way intersection of The Centre (SUBS: correct, this IS the name of a road), Nova Scotia Drive, Cove Rd and South Rd "kamikaze corner" because negotiating it was "like taking your life in your hands".

Boyd said it was encouraging to see what people power could achieve.

When presenting the petition to council in November, he borrowed from The Lord of the Rings, describing the proposed roundabout as "one ring to rule them all".

"On a daily basis, this intersection is frustrating, confusing, awkward and scary. Some drivers are so anxious they avoid using it as much as possible," Boyd told the meeting.

He said it was common for drivers to ignore the intersection's compulsory stop controls on Nova Scotia Drive and South Road.

Whangārei District Council strategy and planning lead, transportation Nick Marshall said with ongoing residential growth in the area, the intersection was likely to play an increasingly important role in moving both local and visitor traffic through the township,

An April feasibility study found the intersection handles traffic volumes of more than 11,000 vehicles a day across its four approaches. The Centre was the busiest road, carrying an average 3562 vehicles daily, ahead of Nova Scotia Drive (3167), Cove Rd (3023) and South Rd (1593).

Marshall said crash data from 2021 to 2025 identified six non-injury crashes within 100m of the intersection.

"While the safety record is not considered severe, the intersection exhibits high conflict potential due to its skewed four-leg geometry and multiple turning movements," Marshall said.

He said the intersection was a critical link in Waipu's transport network, providing internal circulation, an eastern gateway to the commercial centre, and a key route connecting SH1, Waipu Cove and Mangawhai.

The recommended permanent roundabout was selected from four options as the best balance between cost, durability and traffic-flow benefits.

Council staff said it offered the best balance between cost, performance and practicality. 

It would convert the existing four-way intersection into a permanent urban roundabout with some kerb realignment and road layout changes to improve traffic flow, while stopping short of the raised crossings and other pedestrian features included in the quartet's most expensive option.

It would retain most existing pedestrian facilities while adding a courtesy crossing on The Centre.
