Bay of Plenty Regional Council Regulatory Compliance team leader Alex Miller said it received a call about bead-like material having washed up on Papamoa Beach via its Pollution Hotline on Monday afternoon.
The beads were very likely to be the same beads that washed ashore following the grounding of the Rena in 2011, he said.
The regional council had received more than 20 calls about the beads washing ashore since the Rena grounded on Astrolabe Reef in 2011. The calls generally coincided with storms or heavy seas.
"At the end of the day, we don't want these small beads floating in the sea, however they are not an easy item to collect and they generally wash up sporadically with other debris across a long stretch of beach in an area home to diverse flora and fauna."
A protocol had been developed which set a threshold to trigger a clean-up response based on the number of beads that had washed up,
"Basically, this protocol says when there are enough of them in one area we are justified in disturbing the shoreline to clean them up."
A Department of Conservation spokeswoman said there was no specific scientific research completed on the impacts of plastic beads from the Rena on wildlife.
If people see beads along any stretch of shoreline call the BOPRC 24/7 Pollution Hotline on 0800 884 883.
