Transmission Gully update - 11 March 2022


CPB HEB, the company subcontracted to build Transmission Gully, has now had 67 of the 81 remaining safety and quality assurance tests required before the road can open accepted as meeting the required standards.

As at 10 March 2022, fourteen assurance tests are outstanding -  13 with reduced requirements, and one with no change to the contractual requirements for road opening.

The three remaining consent tasks are being worked through with regional and territorial authorities for certification or confirmation.

To facilitate an earlier than otherwise possible road opening, Waka Kotahi agreed to defer 19 outstanding quality assurance tests that were originally required under the contract to be completed prior to the road opening, leaving a total of 81 tests required.  Waka Kotahi also agreed to reduce the requirements for a further 33 assurance tests. These deferred and reduced assurance tests will be completed to the contractually agreed standards after the road opens to traffic.  

Waka Kotahi is not prepared to compromise on the long term safety of the road but we are working to balance this along with the road’s reliability, safeguarding the public from any future financial liability for defects not remedied now, while doing everything we can to ensure people can use this vital transport connection as soon as possible.

Once the road opens, Waka Kotahi will start paying Wellington Gateway Partnership (WGP) for construction, operation and maintenance of the road. WGP have financed the project and have contracts with CPB HEB to build the road and with Ventia to operate and maintain the road. 

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