The nurses' organisation is concerned about hospital visitor rules in Auckland, which are allowing hundreds of people to visit patients every day during Alert Level Four. It says hospital staff are having to deal with poor visitor behaviour, including people refusing to wear masks and turning up in groups. It comes as a renewed focus is put on staff and patient safety, after a Covid-positive patient was admitted to Middlemore Hospital's general ward at the weekend. Michael Cropp spoke to RNZ reporter Katie Todd.
