KEY POINTS:
Organisers believe the stage is set for the former Navy frigate HMNZS Canterbury to be sunk as a diving and marine tourism attraction in the Bay of Islands.
Barring any last-minute holdups, the 3000-tonne, 113m warship will begin its short plunge to the bottom of Deep Water Cove just inside Cape Brett around 2.30pm after a series of explosive charges scuttle the vessel.
