Representatives from two groups opposing the project will also make submissions.
The man heading the privately funded side of the SkyPath project, Bevan Woodward, said he was always confident it would pass the testing and the it was just "one of the many thousands of steps" it had to go through.
Now the testing is complete, the design team is finishing the detailed design plan before the Transport Agency can grant a license to occupy.
The Environment Court also has to settle a dispute with the project's resource consent brought by three associations.
Mr Woodward said if everything goes to plan, the path could be open by next summer.
SkyPath proposal
• What it is - a tolled walking and cycling path under Auckland Harbour Bridge's citybound clip-on lanes.
• Cost - $33.5 million, from a private loan to be repaid over 25 years by a toll of about $3 each way, and partly underwritten by Auckland Council.
