For the mothers at the centre of the drama, the discovery would have life-changing consequences.
What followed was not simply a matter of correcting a hospital mistake, but navigating the complicated relationships, emotions and realities created by years of believing one child was their own.
The story attracted significant public attention, bringing intense scrutiny to the families as they tried to make sense of what had happened.

For Sandra, one of the mothers involved, the consequences have endured long after the initial discovery.
The public attention made an already difficult situation harder, and relationships within the families changed in ways that could not simply be undone.
The case remains one of New Zealand’s most extraordinary stories, raising questions about how such a mistake could happen and the lasting impact on those involved.
It was not a crime, but it left a profound mark on the lives of two families.
In the latest episode of A Moment in Crime, host Anna Leask looks back at the Timaru baby swap, exploring the circumstances surrounding the mix-up and speaking to Sandra about her recollections of the events and their aftermath.
The episode revisits a story that continues to challenge any easy understanding of family, identity and the meaning of being a mother.
