There were also questions as to why the path took such a sharp turn - making it difficult for those in wheelchairs or mobility scooters.
In a statement, the council said the installation of the bollard was a mistake by the contractor.
"The pathway was designed to improve accessibility to the domain from the Rangiora St pedestrian crossing," the spokesperson said.
"The original design did not include a bollard, however. This was installed in error. The issue has now been rectified by the contractor. The path is also being realigned."
The council said it was too early to determine the cost of the mistake.
Work on the realigning the path is expected to be completed on Wednesday.
