The construction companies behind Transmission Gully are suing Waka Kotahi over the roading project, which remains unfinished.

While the road is open, the project is still incomplete after missing multiple opening dates and has exceeded its initial $850 million budget. 

Waka Kotahi claimed there's a clear disagreement about the outstanding work and standards that need to be met to complete the project- aligning with the contract.

Infrastructure NZ CEO Nick Leggett says problems and miscommunications were present throughout all the stages of this project.

"This is the lesson from Transmission Gully- we need to build more, we've got a massive $200 billion infrastructure deficit. We've got to be better at renewing the assets we've got."

Transmission Gully resurfacing is causing disruption for businesses, in the lead-up to Christmas.

After just eight months of being open, parts of the major highway are being resurfaced to prevent future damage, reducing stretches of the road to one lane.

Kapiti Coast Chamber of Commerce co-chair Heather Hutchings told Heather du-Plessis Allan that businesses are going through enough stress at this time of year — and this just adds to it. 

She says businesses are gearing up for a break after a long few years, but product still needs to be delivered between Wellington and Kapiti.
