Rodney Police are investigating the arson of a Maori carving at Whangaparaoa College.
The carvings, which had been commissioned by the college, had only been installed on Monday at the entrance to the Te Maramara a Tane Maori Studies block at the school.
After their installation they were covered with black plastic so they could be unveiled today, but sometime between 7.30pm on Monday night and 6.30am on Tuesday morning the black plastic covering was set alight.
The carvings were scorched and damaged by the black plastic dripping onto them.
Investigations are now underway and police would like to hear from anyone with information.
