Politics have scuttled an event to celebrate the discovery of the "ghost ship" SS Ventnor, which sank off Hokianga in 1902.
Thirteen New Zealand seafarers died and the remains of 499 Chinese men - most of them goldminers - being repatriated to their homeland, were lost in the disaster.
The Ministry of Culture and Heritage was to have this month acknowledged the Ventnor Project Group, which found the wreck about 18km off Hokianga Heads last year.
Using high-tech gear, divers descended 150m to survey the wreck.
While this feat may seem worthy of recognition, complications were probably inevitable. Two parties have competed in recent years to control aspects of the Ventnor narrative.
