Both educators had seen about four principals go through their respective colleges and, in their final year, were teaching alongside teachers who were now the same age as their children.
Their retirement comes as the couple prepares to sell their family home of 42 years on Oceanbeach Rd and makes the move to Wellington.
"We are going to be grandparents," Paul said.
Reading through the messages his students had penned in his thank you card; Paul said it was those words that stick.
"It is one of the reasons why you are a teacher," he said.
Paul often wondered if advancing technology would threaten the future of schools, but quickly dismissed the thought.
"It is about relationships," he said. "That's what it is built on. I don't know if the computers can replace that."
Lita can't help but smile when she talks about her students, past and present.
"When people ask me why I have stayed at the college for so long, the answer is the students, the kids of Mount College," she said.
The former Mount Maunganui College teacher from Tonga said she had felt proud that the school had just appointed its third Pasifika head girl.
"To me, it was like a retirement present," she said.
Lita's career highlights included entering her senior history students in the first national research history competition for The New Zealand Historical Association special studies award in 1988.
She was also proud of the success her students had achieved in the Bay of Plenty Times newspapers in education competition.
Another highlight was seeing their children William and Seini go through their education at both Mount Maunganui and Otumoetai colleges.
Following a family meeting, after their children graduated from intermediate school, the children decided to attend "mummy's school" for their junior years and "daddy's school" for their senior levels.
When their children left school, Lita and Paul decided to be host parents to international students from Japan, Thailand, Brazil and Germany from 1996 to 2003.
"It was culturally enriching," Lita said.
While it had been a 40-year promise not to talk about school at the dinner table, the couple now get to share the thank you messages from students and reminisce about the good times.
"It was time," Paul said.
