A baby has died in hospital just days after her mother died during a difficult childbirth, police say.
The baby had been in critical condition.
Earlier, police named the 20-year-old Hamilton woman who died at Waikato Hospital after a difficult birth.
Casey Missy Turama Nathan died at the hospital on Monday after giving birth at a Huntly birthing centre.
Her death is being attended by police on behalf of the Coroner, but Detective Sergeant Michele Moore of the Waikato Coronial Investigative Team said police involvement in cases like this was standard procedure.
