An attack on two carved pou is an attack on Māori and a successful conservation effort, an iwi leader says.
The posts, which mark either end of a rāhui, or customary ban, at Tauroa Pt west of Ahipara, were cut down and sawn into pieces, most likely last Friday night.
The pou were erected 1.6km apart about 10 years ago amid grave concerns for marine life, especially pāua, in the area. The attack has angered the local iwi, Te Rarawa, as well as conservationists.
Te Rūnanga o Te Rarawa chairman Haami Piripi said it was clear the ''very malicious'' attack had been planned because the pou were hard to reach and the vandal had brought a chainsaw.
