Waka Kotahi NZ Transport Agency hopes it will be able to provide an update in mid-February as to just when Transmission Gully will finally open.
Late last year Waka Kotahi conceded the new $1.25 billion motorway out of Wellington would not be open by Christmas.
This was put down to the builder running out of time to complete safety, quality assurance, and consent tasks for the road to open in time for the holidays.
The four-lane motorway is being built through a public-private partnership (PPP), the Wellington Gateway Partnership (WGP), with CPB Contractors and HEB Construction subcontracted to carry out the design and construction.
Waka Kotahi transport services general manager Brett Gliddon said in a statement today they were working with the road's contractor and subcontractors to support getting the new motorway open as quickly as possible.
