Walkway users jumping safety barriers to stick to their normal routes have raised the ire of the New Plymouth District Council.
Joggers and walkers are being warned to stay off the path leading from Brooklands Park to Vogeltown Park while a wetland is being created in the area.
But people using the Struan Walkway have been seen jumping barriers to continue along their normal routes.
NPDC parks programme manager Steve McGill said the warning signs were in place at either end of the path and it was up to the public to pay attention to them.
"There's machinery and localised work going on and we'd really appreciate the public's assistance while it's under way.
"At the end of the day when the work is done there are barriers in place and paying attention to them really is the key part of keeping safe."
Mr McGill's message to park users was simple.
"Please be mindful of what's going on and please find an alternate route to take."
The project, which started last month, should be completed early next year.
