Middlemore Hospital in Auckland has beefed up security after a woman entered the maternity ward and snatched a two-day-old baby in January.
Neha Narayan, 25, yesterday pleaded guilty in the High Court at Auckland to a charge of kidnapping after trying to take the infant from the hospital on January 4.
The incident sparked an immediate review of hospital security, which has resulted in several changes.
A hospital spokeswoman said an additional security camera had been installed and security cameras on the maternity ward had been reviewed and amended to ensure they covered all entries and exits.
The time it takes for swipe card-controlled doors to close has decreased from 30 to 15 seconds to prevent unauthorised people entering, and parents are required to sign out when leaving the ward.
