This included a total ban on fishing, swimming and collecting shellfish.
A council spokeswoman said staff and contractors removed the blockage, cleaned up the area, and erected the temporary health warning signs.
Leonard said the contamination levels were being monitored regularly and the council would remove the warning signs once the water quality level returned to normal.
When the Bay of Plenty Times visited Memorial Park yesterday not everyone was heeding the warnings.
One visitor told the newspaper she had seen young children swimming in the water.
Another woman in a family group eating fish and chips on the foreshore said she had not seen the warning signs but no one in her group intended going into the water.
Leonard said it was not the first time people had ignored the vital health warnings, and they did so at their own risk as the signs had been put there for a good reason.
In January, the council banned people from swimming in Pilot Bay after wastewater overflowed in Adams Ave because of a blockage believed to be caused by wet wipes.
