John O'Connor Whyte looked in Raetihi for the father who died when he was 2 - but found him at Waiinu Beach.
His father, Brian O'Connor, died in a boating accident at the mouth of the Waitotara River on December 2, 1956. The others from his boat were saved, but four out of five in another fishing boat were drowned crossing the same bar later that day.
Mr O'Connor and his sisters Sonya and Brenda kept vigil at Waiinu Beach for a day last year, 60 years after the boating accidents that claimed five lives. This year they had a memorial rock erected at the beach, and on Saturday the plaque on it was unveiled.
Teddy Tamou, the only one still alive from Brian O'Connor's boat, uncovered it with Ruth Allen, the sister of Malcolm Myhill, who drowned in the second boating accident.
Brian O'Connor's son John O'Connor Whyte, who now lives in Melbourne, has hankered to know his father.
