She was "blown away" to be contacted by the only one of the nine men still alive, Teddy Tamou, now a fit 87-year-old living in Gonville. His name had been spelt Lamou in the newspaper report of the time.
Mr Tamou is to be the guest of honour on December 2.
"He wants to tell the story," Mrs Collins said.
The December 3 1956 Chronicle records that the other men in her father's boat were Mr Tamou, Bing Apou and Paul Bush. None of them could swim well. So when the boat was overturned by a wave as it crossed the Waitotara River bar Mr O'Connor swam to shore to get help while they clung to the boat.
He never made it. They found his body when the boat was washed ashore about half an hour later. They tried to resuscitate him, but could not.
After that they tried to warn the second boatload of fishers from the area that headed out that day. That boat contained Graham Meads, Maurice and Keith Lupton, Malcolm Myhill and Walter Rosewarne.
It was also overturned by a wave on the bar, but not until its return in the evening. Graham Meads, helped ashore by Alan McConachy, was the only survivor. The bodies of two of the other men were only recovered later.
It was a terrible day for the Waitotara/Waverley community, and Mrs Collins becomes tearful when she speaks of it. Others who have contacted her about the vigil have wanted to tell her their stories.
She's not sure how many will show up on December 2, but she and her brother will be there from dawn to dusk.
They are to spend the Thursday night at the Waitotara Hotel, get to Waiinu Beach at 6.30am and set up a pergola and seats on the grass. Many of those attending will be elderly, and there will be quad bike rides toward the river mouth during the day.
Lunch, with some food provided, will be from 11am to 1pm. At 5 there's a ceremony, when people can talk about their memories and wreaths for each family are to be set afloat on the sea. The day ends with drinks at the Waitotara Hotel at 7.30.
