His partner had many wakeful night hours because of their baby's feeding problems and needed her hot drinks to keep her going, he said.

When visitors pressed the admission button, staff operated the buzz-in system from the nurses' desk so there were few checks on who or how many people came in, Trow said.

Sometimes large numbers of visitors at one bed in a room of four patients were very noisy or took up all the room.

''The nurses are that bloody busy they shouldn't have to take on more pressure. They need to have security guards or at least more CCTV monitors on those wards.''

After visiting his partner and baby one evening this week, Trow and their two other young sons passed three men outside the hospital's main door who were openly talking about a drug deal, he said.

Posts Trow put on social media have attracted accounts of similar experiences of food thefts and other bad behaviour at the hospital.

The NDHB said it would not comment on other issues raised or the negative activity on social media following Trow's posts.
