* LifeImitatesArt: There have been a lot of coincidences between Shortland Street storylines and real life, that it has become known as the "Shortland Street Curse".
** In 2003, Shortland Street Hospital had its back-up generator fail during a power outage - less than two weeks later, the same thing happened at Auckland's Starship Children's Hospital.
** The feature length 20th anniversary show featured a helicopter crash, and by coincidence, the day the episode aired, there was a fatal helicopter crash in Canterbury. The show went to air with a last-minute ContentWarning since they couldn't pull the episode without breaking continuity.
* TheOtherDarrin: Justine Jones was recast with Lucy Wigmore in the role, who replaced Laurie Foell who had played Justine for the character's first two years on the soap.
** Chris Warner's son Harry Warner has been played by four different actors since his birth: Joshua Thompson (2002), Callum Campbell Ross (2002-2006), Henry Williams (2006-2009), and Reid Walker (2009 onwards)
*** Daniel Potts was played for his first 3 years by Jarred Blakiston. When the character returned as a full member of the cast in 2009, he was turned into a "heartthrob" and so was recast with Ido Drent in the role instead.
