A Maori trust in dispute with Bay of Islands tourism operators over access through Motu Kokako says further protests are possible but it won't stop everyday boaties going there by barricading the entrances to the scenic attraction.
Rau Hoskins, who chairs the Motu Kokako Ahuwhenua Trust, says the island also known as the Hole in the Rock has great cultural significance to the trust, local hapu and Ngapuhi.
Maori collected kokako feathers there for their clothing and Captain James Cook anchored nearby in 1769 when Mr Hoskins' tupuna (ancestor) Tapua threw a haul of fish to the British crew before leading them to an inlet where his people hosted them.
But any co-operation that existed then has gone, and the trust is in dispute with tourism operators who they say are taking thousands of tourists to and through the site without paying the trust a cent.
