In fact, if Eileen Mary staff don't make Fairlie's bed properly, she strips it and remakes it, living up to her nursing standards.
After marrying Tom, in Havelock North, the couple ran a sheep and beef farm at Tipapakuku on the outskirts of Dannevirke.
"You're never too old for farming," Fairlie said.
The couple's only child Jack was at Fairlie's side for her birthday celebrations and said his mother was renowned for her scones. Nephew John McLennan of Wellington said Fairlie's 100th was an incredible achievement.
"No one else in our family has lived this long," he said.
"Fairlie has always helped others and delivered meals on wheels to people decades younger than herself."
Fairlie also dedicated a lot of her time to St John the Baptist Anglican Church in Dannevirke, where she was choir mistress and organist.
"She was also responsible for all the holy hardware and everything was done perfectly," retired vicar Delaney said.
At 94, Fairlie was still chopping her own firewood and it was as a result of an accident while chopping which saw her "retire" to Eileen Mary.
"She's seen some phenomenal changes in those 100 years," Tararua District mayor Tracey Collis said.
