Waka Kotahi, the NZ Transport Agency (NZTA) has started an open tender process to select a consortium for the detailed project design and construction phases of the Penlink project.
A spokesperson says at this stage, the design work is expected to start in the middle of next year, with construction starting towards the end of that year.
As a next step, NZTA will engage with relevant developers, iwi, property owners and the community to share project updates and the timeline of the Penlink project.
The project scope includes a new 7km two-lane tolled highway corridor, a separated shared path and south facing ramps to SH1.
It will be future proofed for extra lanes.
