A clean-up of the floating wetland in Lake Rotorua is under way after it was damaged by this month's wild weather.
In a statement a Rotorua Lakes Council spokeswoman said post-storm checks had found two sections had broken away from the main structure and small pieces which looked like foam or pieces of sponge, had broken away.
"A team from the company which is responsible for structural maintenance of the wetland is undertaking the clean-up now," the spokeswoman said.
The wetland was constructed in 2012 as an environmental enhancement initiative to help improve water quality in Lake Rotorua.
More than 20,000 hand-sewn native plants grown from Rotorua-sourced seeds were used in its construction.
