The boardwalk was not part of the initial plans the council sought feedback on and would be out of scope for the Innovating Streets project itself, which is limited to temporary works within the road reserve, in line with Waka Kotahi NZ Transport Agency's funding requirements.
Commission chairwoman Anne Tolley said the idea of extending the boardwalk had been around for some time and it would address many of the opportunities identified through the Innovating Streets project.
"Although the trial's community co-design approach received good support, we felt opinion was too divided to make a convincing case," she said.
"We felt it would be better to prioritise the potential extension of the existing Marine Parade boardwalk."
Project leader Guy Protheroe said the council's transportation team would investigate how to address and fund current safety concerns regarding the Tay St intersection outside of the original project.
NZTA urban mobility manager Kathryn King said they were impressed with the way the council approached the trial with a strong co-design approach, which would provide "key learnings" in the delivery of future projects for them and other councils.
