Work on the extension of the shared path has increased in recent days, beginning at the Port Chalmers end as well as at Sawyers Bay, Roseneath and further towards St Leonards.
NZ Transport Agency senior project manager Jason Forbes said working at different locations along the project site was "the most efficient way of managing a sizeable and complex job".
Reclamation was needed in several areas to create space for the shared path, after which land would have to settle before the railway line could be moved and the shared path constructed.
Reclamation settlement was expected to take about six months, during which time the contractor would work on other sections of the path, Mr Forbes said.
In the meantime, a temporary path had been built between Sawyers Bay and Roseneath to cater for pedestrians and cyclists while vegetation was cleared and construction of the permanent path began.
In Port Chalmers, a project site board had been installed and an area formed for the storage of equipment and material and the development of project-related facilities.
The next steps would include more clearance work which was about to start at St Leonards and either side of the Roseneath cutting, and was expected to take several weeks.
Reclamation work would start at St Leonards, Sawyers Bay and Mussel Bay once new safe rail crossing points had been installed in those locations.
