Transmission Gully update – 18 February 2022


Waka Kotahi NZ Transport Agency says recent on-site investigations by Waka Kotahi roading experts shows significant progress has been made by the builder, CPB HEB, towards fixing construction defects and pavement issues required for the Transmission Gully motorway to open.

The builder has had more than 150 people on site since December working on a range of tasks.

Remedial work to manage water seepage on the asphalt surface is underway and the warmer temperature and lack of rain in recent days  has allowed rollers to resume the task of rolling the chipseal road surface. 

Good progress has also been made on contractually required safety and quality assurance tests, with many close to completion. As at 11 February 2022, 57 final safety and quality assurance test submissions have been received from CPB HEB, of which 45 have now been accepted by the Independent Reviewer as meeting the required standards. All three remaining consent tasks have been submitted to Greater Wellington Regional Council for certification or confirmation.

Waka Kotahi is continuing to work with the Public Private Partnership Contractor Wellington Gateway Partnership (WGP), and WGP’s subcontractors CPB HEB and Ventia, to reach a pragmatic solution that meets the legal requirements of the PPP contract to ensure the long term safety and reliability of the road and safeguards public liability, while also getting the road open to the public as soon as possible.

Waka Kotahi expects the builder will provide an update on the timeframe for road-opening in the next few weeks.

Plan ahead for a safe, enjoyable journey. Keep up to date with:
