Waikato district nurses say they're at the end of their tether as demand for their services soars. District nurses, who provide care for patients in the community rather than in hospitals or clinics, say they're severely understaffed and it's causing in burnout, stress and leading to widespread resignations. They also say it's putting their safety at risk. It comes as WorkSafe considers a complaint from the New Zealand Nurses Organisation that Health New Zealand's failure to improve district nurses' working conditions amounts to a breach of the Health and Safety Act.
