"I think Rob had the qualities that I was kind of looking for," she says casually all these years later.
"I wonder what those qualities were," Ron says with a laugh.
"Might have been your bank account."
The banter is loving. Everything about the Smeeds is loving.
On the dining room table sits an unfinished jigsaw puzzle they have been working on together. It's only the third one they've ever done.
"I was actually engaged to another girl at that stage," Ron says of the pea factory days.
But that is a story for another time, he quickly adds.
"Best thing that ever happened."
Dian has a story of her own.
"My dad was absolutely disappointed because he reckoned that school teachers went into the country and he had this theory – you married a sheep farmer. When he turned out to be a dairy farmer, well ..."
Dian and Ron were both from Tuakau and that is where they got married in 1957, in a small Presbyterian church just two years after first kicking it off.
Ron was 24 and Dian was 20.
Today is their wedding anniversary.
The couple has had four children – two daughters and two sons – including a foster son and an adopted daughter.
They have lived on dairy farms in Tuakau and Matamata, a lifestyle block in Horsham Downs, and have been in the Western Bay for about 20 years.
Some of that time was spent in Katikati, where they ran a BP service station, and the rest has been in Tauranga.
