A couple have discovered the much-loved baby they brought home from a foreign fertility clinic is not theirs.
They are fighting to find out what happened to their own embryo - but through the ensuing legal battles, they have also come to love the child, now aged 2.
The couple had struggled to conceive a baby, so a friend offered to be a surrogate. A relative's egg and the father's semen were used.
When the couple commissioned DNA tests to get a visitor's visa for the baby to come to NZ, the results revealed no genetic link to the father, egg donor or surrogate, the NZ Listener reports this week.
