Their photo appeared in the Bay of Plenty Times the next day, accompanied by a story that said their classmates celebrated the birth with painting and craft.
Hyslop, now a panelbeater, still lives in the area, although he doesn't remember the day or Richardson.
"My mum's got the photo, so I do get reminded of it."
He'd just turned 4 and is now 34.
"I wasn't overly happy about having my picture taken."
He doesn't really class himself as a royal-watcher but it's hard to avoid the saturation coverage of Prince William and wife Kate's own baby news. "I think they've got it pretty tough don't they?"
Hyslop is now a dad himself to daughter Samantha, who is about to turn 5.
Another child is expected in March.
Hyslop says he isn't sure whether there will be the same re-enactments going on in kindergartens when the next royal baby arrives.
"I think everything's a bit more PC now they're not allowed to do as much.
"You can't do much without offending someone nowadays, can you?"
Hyslop has fond memories of kindergarten.
"Finger-painting, the bag room where you used to get a little sticker to remind you where you left your bag, playing with friends, riding trolleys and slides and that sort of stuff.
"It was nice and easy, eh?"
