"I was here when they closed in 1992 though. My husband started around the same time as I did and worked right through. He ended up being the truck driver.
"It was sad when it did close, but I had enough biscuits to last for the next 12 months."
Bennett, who oversaw New Zealand's first ever batch of Chit Chats, said he and his wife began working at the factory in the early 1970s.
"I did 10 years," Bennett said.
"My first job was running the chocolate machine, and after a few years the guy who was in charge of that, John Matoe, he left, and I took over from him.
"I ended up in a white coat, looking after the chocolate room and the assorteds as well."
Edwards said most people in Whanganui "worked there or knew someone who worked there".
"It was like a big family.
"Everyone knew everyone, and everyone helped each other out. It was an awesome environment to work in.
"We had a really active social club. Every long weekend we'd try to have trips away, and there were even sporting events with the other sites in Nelson and Lower Hutt.
"Twice a year we'd have two big social functions as well."
The factory had produced a lot of marriages, as well as biscuits, Edwards said.
"A couple of divorces too, probably."
Unsurprisingly, working at a biscuit factory meant there was never a shortage of snacks in the smoko room.
"All the biscuits had to go through the cooling tunnel," Bennett said.
"You'd fill the base trays up with chocolate, get some coconut from out in the shop, and mix it all together. Then the trays would go through the cooler and you'd check them on the first door, check them on the second, pull them out, cut them up and have a feed of chocolate.
"The girls on the line would say 'what was that gap for?'.
"It was always 'oh, nothing, nothing'."
There had been some "real characters" at the factory through the years, Edwards said.
"There are some great stories to be told, and we're hoping they will be told at our reunion.
"I remember an Island chap who used to work in the chocolate room up the top, and I'd be down the bottom packing the biscuits. Every now and then this thing would come through and you'd be like 'what the heck is that?'.
"He had put his banana through to get it covered in chocolate. We always knew who it belonged to."
Edwards posted about the reunion on Facebook last week, and she said the pair had been overwhelmed by the hundreds of responses they had received.
People from across the country are already planning on attending.
"At the moment we are holding it at Barracks Bar, but if it carries on like this we might need somewhere bigger," Edwards said.
"The cut-off date for reservations is August 27, so that gives us a month to organise numbers and things."
Bennett will begin the reunion with a karakia to commemorate those who could make it and those who have passed on.
It will be the first gathering of its kind since 1999 for the Griffin's staff.
The event will be held at The Barracks Sports Bar on Saturday, September 25, starting at 2pm.
