Northland Coroner Brandt Shortland has described the death, "probably" by drowning, of Roydon Rangituatea Tapu at Cable Bay on January 8, as a real tragedy for his partner, his son and whanau.
At the conclusion of the inquest he said he was satisfied on the balance of probabilities and from the evidence that 25-year-old Mr Tapu, of Mangonui, drowned on the day he went diving.
His body was found in the surf near where he had disappeared on March 2.
The court heard that Mr Tapu had been wearing a full wetsuit, dive belt, flippers, snorkel and mask, and was carrying a spear gun attached to an orange buoy when he entered the water. He told a local man that he intended to dive in about five metres of water at the eastern end of the beach.
A friend, and members of his whanau, saw him enter the water and watched as he snorkelled around the rocks. About an hour later, noticing that the buoy had not moved for a while, the friend swam out to the buoy and pulled up the rope, which was attached to Mr Tapu's dive bag, full of kina, and spear gun.
